There was a lot I didn't know about oil before Josh sent me this link.
All you ever wanted to know about oil for your BOSS 302 (and your daily driver). Granted it is a little focused on older cars, but there is so much good information from somebody who is extremely knowledgable on the subject. Much to learn. Might have to come back later and read it again. Some of the points might be a little over my head at this point. Check it out!
