What brand gas do you use?
I've filled up with Chevron with Techron the past two times. The last tank gave me about 30 more miles before the low fuel light went off. I usually get about 300 miles to the tank, and this time I got 330. Although I did not change how I drove, I'll admit I didn't strictly keep track to see if there was any difference in the highway vs. city miles I did.
Will keep using Chevron and see if this is a consistent result. Besides the added peace of mind that the Techron additive is possibly keeping my engine cleaner, the improved fuel efficiency, if real, would more than offset the cost difference.
What brand of gas are you guys out there using? Any good or bad experiences with a particular brand?
I would probably use Arco AM/PM except they do not take credit cards, only debit as a cost saving measure. I have several "cash rewards" type cards and one of them always gives at least 3% (and up to 5%) back on fuel, so that puts them about equal to everybody else. For the same price, I get a "top tier" gas.
In California and most parts west of New Mexico, we can not get 93 Octane, we get at most 91. I'm not sure why that is.
ARCO in Seattle accepts credit cards, although it's 10 cents more per gallon than their cash or debit price. Even so, their price is 20-40 cents cheaper per gallon than a top tier gas.
I shop at Safeway, and for every $100 I spend, I get 10 cents/gallon off at Chevron for that fill-up.
