Oh, c'mon. Differential equation -- give me a break.i've never noticed and hard to imagine unless you were really refined and anal in your driving habits being 100% repeatable, etc.
*if* gas did cause variation in gas mileage i would assume it could vary wildly, like an indeterminate differential equation.....meaning for some vehicles it does make a difference based on engine type, engine condition, others it doesn't.....and then in some cases it might not make a difference and others it might...like city verses highway, flat land verses highway, towing or hauling heavy loads, heavy go pedal foot or not, big brake user...etc.
that was a joke, was making fun of the idea...hence the "*if*" at the beginning of my comment. should have added aOh, c'mon. Differential equation -- give me a break.
Dunno that I would expect that with arco. They are (were?) a big oil company. No idea what their setup is for gasoline production though.the reason i ask is that i seem to get about 2-3 mpg less with a gas like Arco compared to Chevron. Both stations are close to my home.
Ah, good. I'm reassured. :29:grossgary said:that was a joke...
The truly cheap places (and I don't know about Arco either) purchase gas from whatever trucker comes along with some and I've heard (on the Internet so it must be true) that they get discounts for taking the stuff at the bottom of the tank, meaning it could be literally dirty. Between that and the unknown source, it just seems risky, for a high-performance engine, at least. HPHNWSub said:the reason i ask...
A number of years ago I had a job which in which I had a company vehicle. My boss at the time always told us to use Chevron gas because of better MPG's. Anecdotal evidence at best, although I do seem to get slightly better mileage using it in the OB but not enough to justify the .30 or more cost per gallon.the reason i ask is that i seem to get about 2-3 mpg less with a gas like Arco compared to Chevron.
