Does switching back forth between different gas companies for my car affect it in a negative way?
Not only does it have no effect on your car, but sometimes it’s exactly the same gas. Oil companies have for decades engaged in the practice of buying gas off each other. If its stations in Kansas are running low, a company may buy excess gas from a nearby company in Kansas rather than having it shipped in from a distant plant at greater cost. Chevron with techron is your basic gasoline with some after-market detergents poured in almost moments before you pump it. If it makes you feel better, put in the cheapest gas you can find and, about once every ten tankfulls, pour in a buck or two of that over-the-counter gas tank cleaner. It’s the same thing.
