I just moved into a new house and area in El Monte, CA. I've lived in LA for the most part of my life and I rarely see USA Gasoline brand gas stations. Now here, I see them a lot more. I looked up on Google and it appears these USA Gasoline stations are formerly Arco, owned by Tesoro which also owns Shell. Right now gas prices are climbing up again, average is like $4.30/gal for 89. The prices at USA Gasoline stations are far cheaper. I've seen $4.17-$4.20/gal for 89. I would prefer pumping cheaper cost gas but I'm not very familiar with this brand USA Gasoline and their quality of their gasoline. Anyone have experience pumping your car with USA Gasoline brand? I know each gasoline brand uses their own additives in their gasoline to prevent harm to your car's engine. So what's the deal with USA Gasoline? No need to be concern?
