So having these extra additives aren't really essential. It's all marketing. All I'm saying is that you can go to any gas station (branded or unbranded) and your engine and injectors and whatever will still be cleaned.
This...I had a friend who worked for Chevon as well as Atlantic Richfield CO or ARCO who basically told me the same thing.
Especially here in Cali, where all the fuel comes from the same refineries.
