What weight oil?

NAPA has a Valvoline Oil they can order for you called Valvoline Racing Oil and the bottle will have printed on it NOT FOR STREET. Otherwise you will be getting the new low zinc low additive package they have out to protect catalytic converters even the diesel oils are affected. It might say racing oil on it but it must also say NOT FOR STREET. I run Brad Penn myself. I don't know what autozone or advance have.
