I've always used Chevron and Shell and plan to continue... But, is it going to make a difference in the long term health of the car? I know both have additives that are supposed to help keep the engine cleaner... I wouldn't go away from any of the top tier brands. http://www.toptiergas.com/ What do you guys use? Thoughts?

Im sure someone is gonna jump in here and say there is no difference between fuel supplies...... not sure I agree with that by any stretch but, I typically use Shell as a primary, and then Chevron (or BP) if needed. I think any of the three are fine but seems I also squeek another 1-1.5mpg out of Shell for some reason.

I stick with Top tier brands. Chevron, 76 and Shell in that order.

Sunoco 94 (now Petro Can) Shell second

I was however a bit disappointed last week when I hit a Sunoco and noticed a sticker which said it contained up to 10% ethanol, Oddly enough it was the only Sunoco where I've ever seen that on the pump

BP Gas okay? BP and Chevron is all we have up here... both are 93 Octane.

As for "long term" health of the engine? Do you plan on keeping the car for 20 years?

I usually keep a car 3 years or less, then I'm looking for something new.

It's on the pumps at Cheveron, too.

Chevron/Shell/76

And if the Gov has its way it will soon be E15 and all engines will suffer. See it HERE.

How could you even think of using BP gas?

If one keeps the car only for three years then you could argue why go with the top tier brands. I only use Chevron or Shell. I am known to keep my cars for atleast 8 to 10 years.

Sunoco 93, no 94 down here Also use Shell and BP when able. No probs w/ any of my cars.

I have yet to see any evidence that the oil processing techniques employed by various oil refineries vary enough in any significant way to effect the quality of gasoline produced from the process. Sure, additives can be a concern or a blessing depending on your "beliefs" but that is about the only factual difference I believe anyone could argue.

In reality, one could argue the real concern would be storage and filtering techniques employed by your local gas stations. In essence you could say we should really be looking for the more modern gas stations not just name brands.

If you really wanted to be **** you could bring a glass jar with you to the gas station and pump a small amount of the fuel into the jar prior to putting any in your gas tank. Shake up the fuel and check for debris and or water within the fuel. If not, there is no reason to think that one refineries process is going to differ enough from another.

I don't use any of the lowest grade gasoline but with the major brands (shell, chevron,BP, Mobil) --I try to select a gas station with new and clean pumps. when I see an old , run down gas station -I don't care what gas they have --I won't fill it.

I agree with the last post. Gas is gas, stick with major brands and stay with the modern, updated stations.......................................... ........

Forgetting the BP issue, all gas companies are benefitting from our dependence on 3rd world countries for the much needed fuel!

If Somalia or any other African countries was a major oil supplier instead of just pirating ships, selling "blood diamonds" or promoting genocide in their own borders we would surely be there "assisting" um, protecting our interests....................

The storage tanks on those old stations have got to have some debris, rust etc that has collected over the years. I also try to go to the busier stations.
