What brand(s) of gas do you use? Is it all the same?

I've been doing a lot of reading online of debates regarding differences in gas quality, additives, gas sources, etc. among the various tiers of gas retailers. What brand of gas do you use and why? For example, is a Chevron/Shell/76 likely to provide "better" quality gas (cleaner, more additives, etc) for our cars than say Arco, Valero, or some lesser known retailer?

In my four fill ups on my I2 so far I've used Shell twice and Costco twice (regular grade). Am I getting a lesser quality gas by getting it at a retailer like Costco? Or is it all the same?

gas is fungible. which means all gas stations get the gas from the same pipeline throughout north america. there is no costo gas or shell gas. The shell gas stations add the shell additive which makes it shell gas.
so, no difference except for the additives which may or may not help. i normally buy shell additive (techron or some such) separately in those bottles and add it to the fuel every 10K miles when i do the oil change. much better to do that and it keeps the engine equally clean.

Awhile back my internet search told me that for regular gas Texaco puts the most addative in, and Chevron is second. Shell only puts addative in their midgrade and premium. So when out of my area I seek out Texaco or Chevron at the lowest price.

Within my area I've found that the difference has more to do with the particular station where I buy then the brand. For example the local Chevron station sometimes gives average mpg and other times very good mpg. One local Texaco always gives great mgp, another one doesn't. I found an Exxon in near-by Florence which always gives great mpg. Oddly the Chevron is always highest price, the Texaco and Exxon always low. I think ownership is a factor. The Chevron owner owns several stations and is an a.h. to his employees. The Texaco guy is fair to his employees and is always trying to undercut Safeway gas.....which can be good or bad, but is always crowded.

gas is gas is gas. The only thing that differs is price and the turban heads that sell it.

Gas is made from oil from a variety of countries, some who wear baseball hats, etc. We water it down with ethanol to make use of our surplus grain.

I try to buy the cheapest for the card I have, which is wawa. I get a sandwich and points on my purchases and reciepts that double as coupons for use in the store. Some of my coworkers say that wawa gas makes their check engine light come on.

When I had my supercharged tacoma, it loved shell v power of all. Otherwise I use wawa. Some poeple say top tier is the only gas you should use as well as little to no ethanol as possible.

Its not going to damage the car, so keep that in mind before you pay more or drive out of your way to get it.

There was a lengthy discussion on this in this thread.

What gas brand does everyone use??

I usually use Chevron for all my vehicles. Shell and Costco would be a substitute when it isn't available.
