Have you tried out Gas from different Gas stations? I've tried out Gas from Chevron and Shell and found out that the Quality of Shell is slightly better than Chevron. Whereby I'm able to go on more miles than chevron at the same price. What about the other gas stations? Such as 76, arco, costco.. etc. Is there really a different on the quality of the gas? Why is it so?

I prefer Shell compared to other gas station in my country. The price is the same in my country but I do feel that there's a different of the quality compared to others.
