I am not trying to give a plug to a manufacturer, but have you noticed how often Chevron products get mentioned in a positive light at this web site? Chevron conventional motor oil, based on VOAs and UOAs, is considered to be one of the best conventional motor oils. Chevron Techron gasoline additive is one of the top performing fuel system cleaners. BOBISTHEOILGUY did some testing of some fuel system cleaners and Techron looked good along with Neutra and Lucas. Chevron makes some of the top tested diesel engine motor oils. I would use Chevron gasoline if I could buy it locally. From what I have been able to find out, Chevron makes some good products.
