How to increase your MPG buy almost 2
- Thread starter SwampAss
- Start date
The trip computer is optimistic by 2-3 miles for me as well. I always compare it (yes...I can't help it) to the miles traveled / gallons put in. I just got the MS CAI put on yesterday, so I will have the rare opportunity to see if increases, decreases or has no effect on the gas mileage in two MS3s.
anyone figure out what brand fuel walmart/samsclub/costco/7-eleven etc is most like?
supposedly the fuels coming through the fuel pipe lines going state to state are the same (ie. there is only 1 pipe line - not 1 for each brand/company?) - the additives get added and tweaks performed by the local refineries to give it the branding flavor (techron, etc)?

I think variety is the spice of life, so I get gas from all sorts of places. Mobile is one of the ones I stand by when it comes to a high quality imagination of performance and mileage gains.
Unless it's an emergency, I buy from whoever has the cheapest gas. I've never noticed a difference in mileage.
However, I recently changed my driving style, and my mileage went up from ~25 to 30 mpg. Yeah, a 20% improvement, all from my right foot.
I check my mileage at every tank. Like clockwork, I got 24-26 mpg. (If I did a lot of highway driving, I might get 28.) My driving route hasn't changed, and now I'm consistently getting over 30 mpg. With a lot of highway, I get 32-33 mpg.
I'm not driving slower either. A Miata isn't exactly comfortable to drive at 80+, even with the top up. I still do 70 on the highway and I push it in the twisties. The difference is, I look ahead. Way ahead. I pretend I don't have brakes.
If I know there's a stop light ahead, and I'm going to have to stop, I let off the gas immediately. Depending on how far away it is, I may coast (step on the clutch) all the way to the light.
Sounds boring, right? Well, on the curvy back roads I drive to work, I try not to brake either. So I get to pull some g's through the turns.
Years of autocross have helped, with the cornering ability for sure, but even more with the looking ahead.

I use shell exclusively and still average liek 18 mpg 
However, I drive short distances mostly... work like a mile from my home, plus I get on it every chance I get.
When I did do a long trip (from VA to MD to DC), I got 30+ mpg's.
wish I got to do more long trips...

what i meant to say was that walmarts gas is like their products...cheap and crappy....sorry i thought that would be obvious
aaaah, ok
that is a pretty big generalization though as they carry a lot of name brand items in addition to the el-cheapo's. (have not tried the wally brand gas)
as I stated - have used costco & sams premium gas for years in my 3 high performance vehicles - never had issues - hence my curiosity for who manufacturer/mixes it for them.

You guys blow me away. Pretty much, gasoline is gasoline, brand to brand. It is so closely regulated and scrutinized that really the difference from brand to brand will be incredibly small. It all comes from the same basic oil tankers, to the same basic oil refineries. Shell is doing more then a fair amount of off-shore oil drilling, and trying to break ties w/ the Oil Sheiks, so I almost expect their fuel to cost a bit more. However, I usually buy from ARCO or whomever has the lowest price for 91 (the highest it goes around here) that is still a power-player in the oil industry (Shell, BP, Mobil, etc.), and I don't see a difference.
Just as a thought, the difference you are seeing could be explained from the use of "oxygenated" fuels, or through the use of higher ethenol content. Both of these changes could result in less energy per gallon, which might be causing your right foot to put more into keeping the car at the acceleration and power levels you are used to, as well as a car on cruise-control using more fuel to maintain speed. It would be a small difference, but it could add up.

Ahh, you are partially correct. It comes from staying out late, and while on the way home, Fourthmeal is the only meal available.

Filled up yesterday, so I will have some comparo numbers up next week. Of course it isn't going to matter as I didn't look at the toptier list and filled up at an Exxon. For some reason (the billions of dollars of profit per quarter they have been raking in) I thought they would be in the toptier. Oh well, real data will have to come later. lol
