miles: 245
mpg: 30.6x city driving, and 33mpg highway in the past with turbo
EPA: 26/33
% improved ~18%city and 0% highway? this is including spooling my turbo while rolling around town on 14" delsol wheels. 32psi front 36 psi rear tires. 10"sub in the trunk, and spare tire. should i up my tire pressures a little more?

 

Can't give you "credit" for approximations, not that I'm really keeping the list updated any more, anyway.

Yeah, more pressure will help. It'll help more than you think. It's pretty surprising. Try something like 42-48 psi. Hardcore hypermilers will tell you to run 60! More pressure keeps the tire rounder and you lose less energy to heat in the flexing of the tire, less rolling resistance and all that.

Fun fact, car was rated at 250/258 at the crank when it was new, and it dynoed at 280/316 with the mods I have, and I'm still seeing a higher percentage improvement over my civic which wasn't modified beyond the engine swap. I've yet to hypermile the car on the highway, though I am seeing about 20mpg in the city, which is a 33% improvement over the EPA rating of 15 for the 6-spd. I do all my calculations with a nifty little app on my droid, tracks mileage stats and cost per day cost per dollar figures. It costs me about $4.50 a day, or $0.166/mile to drive the S around town.

Not too shabby for a cement salesman's saloon.

 

Okay, I finally found the TRMPG spreadsheet. (ya got me... I finally LOOKED for it, it was actually easy to find) Updated the PDF in the first post with omgwtfbbq's Audi and IwinUlose's F150.

Let the games continue! Nobody's cracked the top 10 in a long time, I guess gas is too cheap.

 

Still 17th? Man I'm gonna disconnect half of my fuel injectors.

 

I'm thinking about wiping the list and starting over. Give people (myself included) incentive to work toward a more achievable goal for a while. Maybe reset it every quarter?

 

I'd be in a better position if we went with combined fuel economy, I rarely make all highway trips anymore. I'd be at like 32% using a combined mpg of 18 for my car.



Hint.

 

Ah, but everyone else would be using combined, as well. So you'd be in about the same place.

I like using the HWY number because it's the highest published number... and anybody can exceed it by 10-20% in any vehicle in ANY driving environment if they try.

It's easy to NOT get good gas mileage. I drove to Starke last weekend and was in more of a hurry than I usually let myself be in, so I just drove "fast". Accelerated briskly, drove 10-15 mph over the limit everywhere, and when I got there, I had just under 32 mpg. That might sound good, but my car is rated at 36 mph highway and I almost always exceed it!

 

That was in the yaris right?

My MFD has instantaneous MPG, and trip average MPG, as well as time driven, and average speed. If I get on the gas the instantaneous can quickly get down to single digits. The numbers are a little off because I'm running more boost and using a different fuel map, but they're usually pretty close.

The first tank I went though after I got the car while I was enjoying my first forced induction vehicle came out to 14.91 mpg. But every time I hit the gas my face did this
