Day 3..... I stunk it up on the way to work...it's been so windy. I rode my bike yesterday, so I didnt need to pull out the SS. I did put 42 miles on it, I only drank a half gallon out of my camelback....so thats 84mpg, can I count that??

The real trick to getting 40 mpg is to convert from L/100km to UK/Canadian gallons. The 40 mpg stated is actually 34 mpg in american gallons.

This is interesting! I wish you could do a tank on almost all city driving rather than highway. Compared to my low 20's mpg, this looks amazing...but I do 95% city and average 18-20 mph. 75% highway driving is a totally different animal.

What I'd be interested in seeing is a fuel efficiency coefficient(?) (rating) based on your average mph, distance, mpg, etc., in order to extrapolate, for example, 22.5 MPG at 20 MPH into X MPG at 35 MPH.

I've been trying to think of a way to do that, but got stumped.

LOL....
I've been bashed before for being too negative, or a know it all, so I let the conversion slide. 34.1mpg actually.
I am seeking input, not just to correct others math.
No problem, but as you can see ..you can do better if you have the inclination

Clevelandhhrss

Don't be stumped, I'll make a spreadsheet for you in excel. I only posted the first few parameters of my excel spreadsheet because it would not fit on the sceen, in one single line. When I get through with the tank, i'll begin to put together a correlation between speed, average trip distance, and %city/highway mix...so that anyone can check how well they drive for efficiency regardless of there specific driving environment.

One thing to remember is that I change my techniques based on the situation. For example, if I am stuck in city traffic, but the lights are short, I'll pulse and glide(coast), ill slightly annoy the drivers behind me, but we'll all get there exactly the same overall speed, and save a little gas. What is the point of racing to a red when you are 100% sure it will be red when you arrive. If the lights are long, ill cut off the engine until the cross light turns yellow, then turn the key and pull away in 1st........2nd on a downhill of course. If the lights are not always red, or I am the last to arrive at the light (happens a lot and i like that), I'll time them and maintain a constant slow speed, coasting and braking slightly , so that when it is green i can pull away in 2nd or 3rd while the gas hogs in front of me race of to the next red light.

All this means is that for nearly any situation short of new york cabbies (honking when the cross light is still green so you will be the first through) you can get 27+mpg. Pulse and glide is great in stop and go highway traffic, even better than cruise at 65. If you do stop for a long time, just turn your car off.
Hint: make sure you turn your lights to manual from auto at night so as not to alert anyone to you gas sipping ways.

Lol...newsflash....get up too late to make breakfast, and Mcdonalds will crush your mpg.

I actually turned my car off three seperate times in the drive through (it is actually faster than walking in at this location) and use idle to pull forward each time. I probably doubled the mileage by this alone considering it took them 12 minutes from start to finish to get me fed. It would not be much of an experiment if I just drove back and forth to work at 36.3 mpg anyway, so I actually wanted to see how bad it would be. 17.6mpg is REAL BAD.. Anyway Now you know tat if you drive a couple of miles to the local drive through, and leave you car on the entire time, after a cold start up----12-17mpg is probably what your getting. Ill mix it up this weekend with some longer trips to see if i can do a 40mpg drive at some point.

Day 5? i think...lol Mysteriously my trip to and from work has dropped from 12.2 miles to 12.1 then 11.9 and now 11.6. I think I have discovered a worm hole in route 90.

Ignore the trip mph....as the mileage racks up, the resolution of the avg mph (1mph) is screwing with the split odo (0.1mile) so this parameter will be inaccurate.

Ok I am not trying to a smartelic but just making a statement. I drive 31 miles one way to work as of right now I am getting 32.6 mpg NOW when the wife drives we get about 29mpg but I have noticed that she likes to accelirate quikly when she takes off. Will that alone explane the milage differance?

Drops to 24 when my wife drives.

As for the wormhole on I90, they filled in some potholes, decreasing the up and down distance. Potholes in Cleveland have been known to swallow cars.

And.... a Real engineer would have posted an Excel spreadsheet with graphs.
