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.

 

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:

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.

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.
