I agree with the article and never believe snake oil salesmen. They all sound like Obama to me. Great picture. Automobile repair is where most snake oil is sold. Not one thing works. Cow magnets, water for fuel, tornadoes, miracle additives, etc.. I will add, changing your oil too often can cause premature catalytic converter failure, and as far as good fuel goes, some car manufactures call for top tier fuel.
“changing your oil too often can cause premature catalytic converter failure,”
Huh!?! I never heard of this one, but I’m willing to learn something new. Can you tell me why this would be? Lower initial wear on the engine, which would increase blowby perhaps? Just guessing.
