if this has been answered somewhere, I'm sorry for the redundancy.
What Octane should I be running in my SS???

The engine is so noisy, I wouldn't notice knocking if it were on my head.

JIm

Min 91 is recommended fuel. I run 93 and my computer shows virtually no knock at all. The fact that it does detect even an occasional small amount at high load levels tells me that running 87/89 octane will drastically reduce performance and even fuel economy due to the spark being retarded during acceleration.

BTW - one persons noise can be another persons music to their ears!

How are you displaying the knock detection from the computer? Do you have a scanner or something else connected to the diagnostic connector?

I thinky snoopy tested this theory out over 4000 miles. Maybe 1-2 miles per gallon difference in mileage 87 vs 91 in the 2.4. I didn't notice any difference in normal driving with my SS running 87 vs 94. If it is a difference, it's small so I can't tell if it's octane or just my driving that specific day. I get 36mpg overall out of my SS running 87 btw.

As far as performance I have no Idea.

I have HP Tuner suite and it has the ability to monitor in real time and log up to 56 things at one time while the car is in use. You can then play back the run/trip in super slo-mo for detailed analysis or fast forward to get max levels of things. Still learning how to use it but it's pretty cool stuff. Bought a few books to help with the learning curve.

Basically the software runs on your laptop and connects via a usb connection to a "black box interface" which plugs in to the cars data port.

how in the hell are you getting 36mpg best I have ever seen is 28

Im with crazy steve. (Down hill doesnt count)

I normally average 27 with city/highway driving.

That sounds very cool! What was the approximate cost of the software and interface? Is it a USB or Serial connection to the laptop? Could you post the link where you got them?

I've read about some of the interface chips that can automatically translate data from the on-board computer and just dump it out as Serial data. I've been thinking about using a micro-controller to get some of those stats and display ones I am interested in. Thing like the knock sensor detecting knocks would be extremely useful to know. If we see a lot then we can try using higher octane fuel, etc to see if it goes away. At the moment I'm not concerned with trying to install a new performance "tune" while the HHR is still under warranty but I would love to get access to all the other stats the computer has on board. That would be awesome.

It's real easy :)

After I do my anti-hypermile tank, i am going to imagine that I will land between 26-28 mpg.

I really can't wait to get back to hypermiling. Going from 36mpg back to 27mpg is torture. I thought it would be easier.
Nope it sucks, I catch all the red lights, i can't time the lights, people are forever in my way, i seem to constantly hit my brakes, I shift more, i have to watch for the cops, and my average mph has is currently 1-2mph faster than my hypermile tank. GRRRRRRRRRR

I can't believe more people don't hypermile with a manual hhr. You guys really are missing out.

I'm going to try to get 38 mpg out of my next tank. But no drive throughs, racing eclispes, and no parking garage and ill use 94 sunoco. So my new goal is to not fill up until i reach 550 miles. and fit less then 14.51 gallons back in the tank.

I thought the whole idea of buying the SS was to have fun! I am cool with my stop and go-fast, have fun without being an ass, 22 mpg avg commute trips. If I wanted a true gas sipper I would have bought a Mini Cooper base model.

how in the hell are you getting 36mpg best I have ever seen is 28

I am averaging 29.7 around town. The 08 SS does just a bit better that the 06 2LT with the 2.4L engine. The 06 LT averages 25.3 with the wife's driving and 28.5 with me driving.

A drivers driving style has a lot to do with average miles per gallon.

The part that everyone seems to miss is that inefficient driving is not inherently "fun". It's just inefficient: read poor. My average speed while I was hypermiling is a couple miles an hour slower then when i am not. That means that all my "fun" doesnt add up to much speed. I get to my destination nearly at the same time...like within 10-15%, however my mileage is 25-40% lower.

Thats not fun, that's just poor driving.

An I still cannot fathom how anyone here could get 22mpg overall. I hit over 100mph (yes it's dangerous...and no don't do this at home) on every drive on my way home from work for at least a mile. I try to average on the 9 mile stretch 70 (10 over the posted) to and from work. I don't turn off my car ever at stop lights, no ice-off coasting, no slow accelerations, and i pass cars like they are obstacles. I attempt to be the second fastest thing on the road everyday.

I mean this is my anti-hypermile tank.

So far, I have found that its just stupid.

1. I burn fuel at a stupid rate

2. I technically am 10 over the speed limit always, and do very short burst at 40+ over the limit. Which is seriously breaking the u-no-what

3. I wear out my suspension, brakes, oil, tires, and engine for no real reason. I am not in a race and moreover I don't get to my destination faster

4. I might get a ticket...I very good a loking for them, but I tire of this stupid cat an mouse game where if they win i get higher insurance and a hefty fine, and If i win i get ---see above item #1 and #3. That is a lose-lose

5. If i am involved in an accident, you don't need to be an engineer to figure out how my survival rate goes down for every mph over 35mph I drive. Remember your kinetic energy equations....the "v" is the biggie.

At 70mph or faster that some of you drive you better hope GOD, not onstar, not airbags and crumple zones saves your A$$.

As I always say, do what you want with your HHR because its yours. But SS stands for Super Slow in my book.

Found a few other links that may be helpful in finding out what the brain of the HHR is thinking about:

http://www.digimoto.com/

http://www.ozenelektronik.com/

http://www.scantool.net/

I'm thinking about using one of the ELM chips to build my own instead of using one of the canned software/hardware packages. Keeping my options open at this point.

http://www.elmelectronics.com/index.html

I run at least 92, sometimes 94.

Where did the rest of the posts go that were in this thread?? Several had to do with tools which could display more information from the HHR's computer and in particular if the knock sensor was detecting anything. That relates to the Octane level of the fuel and would show that performance is lost and a better grade of fuel may help.

If the posts are going to be removed would the person who deleted them be kind enough to provide an explanation? There was nothing I could see in them that violated the forum rules.

The link post was restored.
Stay on topic!

I usually run 93 Marathon. For a trip to the track last week, I put in a few gallons of 100 Octane unleaded as knock insurance, and the mileage declined noticeably.

I am just shy of 10,000 on my SS. After the first 1,000 or so miles I tried 87 octane and then back to 93 and then back to 87 where I have stayed. I really can't tell any significant difference in either performance or milage. I took a 3,500 mile vacation in early July and averaged 30 mph for the entire trip and frequently traveled at 70 to 80 on the Interstates. I drive pretty conservatively to work and often back home when I use it for that which is not too often but on the weekend and evenings I drive it to enjoy it. The SS gives the option of working well as an economy vehicle but it also does well as a performance vehicle. I am a motor head, use to race dirt ovals, have a Harley, 32 Ford roadster with three dueces and a F-100 with a 302 roller motor and the SS is definately an enjoyable car to drive. By the way, I use 93 octane in both the Harley and hot rod but they run measurably better with it.

not being an ass here,but why even get an ss if you're going to do this??? as you said,do whatever you want,but i find it silly to try to save gas on a performance vehicle. just get a regular hhr and save all the hassle...

In regards to someone looking mainly toward economy I can see several reasons to buy the SS over the regular HHR:

- Ground effects make it cut through the air a bit easier (probably a little less wind resistance.
- Smaller displacement engine (only 2.0L) which can help economy when taking it easy.
- Engine came with Mobile 1 which several people claim can get you an extra mile or two per gallon.

- The SS handling package is awesome and it just drives great (why not have something that handles great and gets good mileage)
- The SS just looks cool and the interior rocks.

- If you ever get into a tight spot the extra HP is there if you really NEED it. I think it is better to have it an not need it than need it and not have it.
- Ah yes, every once in a while you can jump on it and have some fun. After all got to make sure the turbo still works.....

To get back to the spirit of the original post we need to get more data on how the Octane of the fuel plays a role in the performance/economy of these turbo charged HHR's.

- When driving in a mild mannered way with an eye toward economy is there any difference using the higher octane fuel or will plain 87 octane work just fine? This assumes someone has a light foot.

- On the flip side if someone has a heavy foot and is into the turbo a lot then how noticeable is the difference (if any) when using lower octane fuels. Does it really cut down on the performance?

Did you read anything I wrote..It was a long post lol????

First I already have an SS

I've explained why many times.

A "performace" vehicle does not inherently get poor mileage. It takes a poor driver to accomplish that.

I find it silly to waste gas, why waste gas and money and the integrity of my vehicle for NO-GAIN. There isn't a sinlge person on this forum having more fun with their SS than myself.

I would not hypermile at the track, or strip.....but I-90 is neither.

And my above post explained why poor inefficient driving is a hassle imo.

Why would I get an LS OR LT, I still have yet to find a single person on this ir any other hhr forum who gets better mileage city or highway. In fact my 100% city mpg is probably better than 90% of hhr owners (ls,lt, and ss) average highway. An I take short trips, from cold starts, and parking in a lower level garage......three MPG destroying conditions.

Please if you can take only one thing from any of my post. Let this sink in.

1. My average speed over my hypermile tank (517.5 miles 14.4 gallons) was 37mph @ 36 mpg

2. My average speed through my anti hypermile tank is 39, maybe I'll get it to 40 or 41mpg by the end of the tank @ currently 27.8mpg and going down...lol


Anyone getting lower then 20%+ of my anti-hypermile FE is either taking a lot of 2 mile trips from cold starts, spending a great time idling in parking lots and fast food line, is running their car airconditioning for 30 mins before they pull away,

OR NEEDS TO LEARN HOW TO DRIVE!

And mighymouse...seriously, where is the rule that states "anyone driving a performance vehicle is required to drive like a idiot, burn gas profusely without actually going fast, and wear the tires off it while driving to work and such"????

Seems robotworkshop "gets it". Thanks for summing it up without me having to beat it into someone. :bow:

My "Absurd Mileage" Pursuit was done on a full tank of 87. I cannot attest to dyno numbers on hp loss due using 87 in an SS. However I noticed ZERO problems over that 517.5 miles and 14.4 gallons. I always have more HP then I ever need to pass, merge or drop a fool in my rearview.

I will probably never use anything else, ever again, unless I am carrying a heavy load, driving in extreme heat, at altitude or get that tune.

And mighymouse...seriously, where is the rule that states "anyone driving a performance vehicle is required to drive like a idiot, burn gas profusely without actually going fast, and wear the tires off it while driving to work and such"????

My 2¢ is you're not an idiot if you drive a vehicle the way the manufacturer designed them to be driven. I don't know why you have to flame a person for driving a performance car like it is capable of being driven. Mightymouse didn't flame you in his post he stated he wasn't trying to be an ass and only stated he found it silly. These type of statements are why I have been on a sabbatical from this forum. I may need another one.

Hey ChevyMgr,

I hope you don't take a sabbatical from the forums just because a couple members may not see eye to eye on a few issues. I for one enjoy reading your posts and you have added a lot to these forums.

The HHR SS is a great machine and it is a rare package in that it handles awesome, can get great mileage, and can scoot right along when you kick the turbo in. It seems to be a fantastic balance and since it can sip gas or fly down the road I think it is cool to discuss both options and let people drive it however they like. No reason get into which it best overall. It just boils down to what is the best for the individual owner/driver. Either way is fine.

I've got an Automatic myself as a daily driver but if I had the extra $$ would love to get a second one with a manual as a toy that would get tuned, tweaked, etc just for fun.

I agree. It's just the way they state their disagreement...Lets see, that brings some quotes to my mind... hmmmmm....

To each their own...

Live and let live...

Chill-axx dude.
That was definitly not a flame.
You would know if I flamed, because i would be promtly banned afterwards:D

I feel that to many people tell me how to drive my SS. I understand that some is SS jealousy (in a good way) for those that bought in 06 and 07, and some is (lets call it like it is) an anti-green inclination to those that abhor hybrids, hypermilers, speed limits and the like. For some this is there first turbo car, or first fast car, or most affordable American sportster. I understand that many have waited an anticipation for the chance to drive an SS, or just to see one. It is "telling" that you have a feeling about how this car is "capable to be driven" I didn't tell you or any of the other (remember cill-axx) pedal mashers to buy ZR1's did I?????. I have been told no less then 7 time about "what hhr i should have bought", mightymouse is just the most recent.

This is an hhr forum not a EVO forum or Z06 forum. Many more people care about mileage then HP. Look at what is selling, and what GM is making. I want to HELP people that get poor mileage. I want to help them without buying some bull$#it bolt on that doesnt do crap. I want to tell them that you CAN get 36mpg overall without breaking laws and causing a crash on the highway.

No one needs to know how to step on the acclerator until it stops going down. And no one needs to know how get 22mpg or less...lol

I have answered the question with science about Octane. My mileage proves it. I do better then sticker with 87 in all conditions WITHOUT hypermiling. Moreover the tune works on 91....that should be a big hint that those of us without it dont need 91.

And lastly, sorry if I offended anyone. Seriously.
But I realize how aggresive i would have to drive my SS to get 22mpg or even 25 overall. I only hit 90mph on the way home ....twice....stupid avg mpg saids 27.9......i can't even get poor mileage when i try. Good thing this tank only lasted 400 miles....i can't wait to shoot for 38mpg overall...lol
I've never said chill-axx in real life before, but it felt appropriate here...lol

Don't be cheap if you have the SS. Buy the good stuff, don't just try to get by with regular. Let's throw down a little chart for those who think it costs so much to fill up with Premium VS. Regular.

Using the Chevron by my house I can get 87 octane for $3.79. If I fill up 14 gallons at that price I pay $53.06

If I go reckless and put Premium (92 octane) in at $3.99 a gallon, 14 gallons I spend a whopping $55.86. That's a whole $2.80 more! Filling up 3 times a month, over 12 months, that's $100.80 more than filling up with 87. If you are telling me that you cannot spend 27.6 cents per day extra on Premium fuel, than please, sell your $24,000 HHR SS and get a Hybrid.

Get the good stuff, drive the performance car like it was meant to be, use the turbo and get over it!

That's a bit of a bigoted statement. There's only the good people (you), and the bad people (people who accelerate faster than you do). As for the self-righteous ones who sell their SUV to buy a hybrid (or other "economy car") and then claim their "greenness"... uh... you ain't any greener than the guy driving your old SUV. That vehicle didn't go away. It's still burning gas and emitting carbon. But you get to be self-righteous (read as "moral relativism") about you paying less for gas... under the guise of being "green." Just for you, I think I'm going to pour a gallon of gas on the ground the next time I fill up. That way, all your hard work at making this planet a better place (your "greenness") will be wasted in one fell swoop. Or... maybe just be a little more realistic about what you promote to others as "being green."

I want to tell them that you CAN get 36mpg overall without breaking laws...

I must have missed your scientific analysis of octane. Can you point me to it? Also, your assertion that a tune works with 91 octane means that an untuned engine doesn't benefit from 91 octane is a logical fallacy that confuses correlation and causation.

I know that I take the risk (major sarcasm here), but I am a big boy. I also took the risk by only changing my oil in my s10 every 3000 miles *2 or 3 or even 4. Still runs like a champ.

how in the hell are you getting 36mpg best I have ever seen is 28

thats for sure my best is 24 overall. there are 2 things guys lie about the most #1 the size of there "unit" and #2 the mpg on there cars from Maxum mag a few years back:lol:

That way, all your hard work at making this planet a better place (your "greenness") will be wasted in one fell swoop. Or... maybe just be a little more realistic about what you promote to others as "being green."



Except that you ARE breaking the law (http://www.dmv.ca.gov/pubs/vctop/d11/vc21710.htm) (at least in CA, and almost certainly in most other states).



I must have missed your scientific analysis of octane. Can you point me to it? Also, your assertion that a tune works with 91 octane means that an untuned engine doesn't benefit from 91 octane is a logical fallacy that confuses correlation and causation.

/that is all.

:roll:

?? Wow ..LOL

I am Brown..not green actually
I stated early on that I could care less about the price of gas. At my wage, I'm not feeling the pain. But many others are, and obviously my posts are for them.
I never said anyone was bad. I hope you all put as much gas into your HHRs as you like. Its your hhr and your money. You can use all the gas that I do not, I'm cool with that.
If your gonna spill a little gas for me. Spill it somewhere else than on the ground please.
I've helped build many many SUV's, trucks and cars. I took my check with a smile, regadles of the fuel economy of the cars I was building :)
My concern is with my vehicle and anyone else that want my opinion.
Lets say i do work hard to save a litle gas (i don't so i wont take credit), and a small amount of emissions, and keep a few pennies in my pocket. Is that a bad thing?
I'm not saving it for you....why waste it for me.

I won't waste time debating octane. My sticker saids 21-29 the small print saids a high of 34 can be expected on the highway. A reduction in power or mileage can be expected if I run lower than 91. Obviously I get a lot better than that, that is all the proof I need. I said n all my posts that I don't know about power, and don't care. But your a very educated peron (you mentioned some acomplishments in another thread) so I know that you just threw that last sentance in to get me wound up,.:nuts:

thats for sure my best is 24 overall. there are 2 things guys lie about the most #1 the size of there "unit" and #2 the mpg on there cars from Maxum mag a few years back:lol:

It's really not at hard. Or any feat. There are many people doing much more with less. I jut haven't met any here.... yet. I DID IT just because. Now I DO IT because I like it :smile:. I am not sure what is illegal about Hypermiling accoding to XXL...but the cops that have occasionally pulled behind on the highway after giving out a few tickets dont seem to mind at all.

The ladies tell me its the guys with the loudest exhaust, bigest HP engine, or red sports car always chirpin the tires are the ones making up for something... :lol:

I you really care. PM me. This thread is ong enough ..lol

WOW Didn't mean to start an epic battle. I forgot to read the owner's manual and didn't notice the sticker (DUH!) inside the fill-up hatch.

FYI, in Buffalo,
87 is $3.89
89 is $3.99
91 is $4.06
93 is $4.15

When I last filled up in PA, 93 was $3.81. I just wanted to hear what you guys were running and with what results.

Using 87 I can get low 30's on the highway if I keep it under 70. Round town, I'm getting 24. I occasionally "drop the hammer" for the sheer grin factor or to get in/out of traffic.

As for the "Green" discussion, I ride my bicycle to work.

Right on Jeda. My bike is my "real" performance vehicle, well bikes, since I own three. I use to ride my bike to work on the weekends (old job was 25 miles from my apartment) but alas my new job is 12.2 miles away now and they have showers i'd wouldn't even wish on my worst enemy.
Gas is cheap to me. I don't even read the price when I roll into the gas station.
Low 30's is pretty good at 70. I just finished my anti hypermile tank as i was driving home with my son. 39mph at 28mpg. Tomorrow i'll fill up with 94 and go back to hypermiling, It's been a little cooler so warm-ups will take longer, and ill have to up the pressure in my tires. But i am way, way better at this after 500 miles. Maybe i can crack 37 overall. The real money saved is by the gallons that I don't use, not by the price of gas. Driving an extra 125 miles per tank adds up much faster then $0.25 per gallon...lol

Although it looked like a battle, my absurd mileage thread has over 2000 views, so somebody cares about mileage....It will really twist their noodles when i hypermile my SS with a full hahn kit. That will bring a new meaning to drop the hammer.
