Its about that time, I've been reading up on this subject on here. I noticed a lot of people have been using thicker oil on their bronco. I have a 302 don't know what oil was used, I bought from a used lot. My oil pressure is fine right now runs normal. Should I go all out and use the 20w50 that I see a lot people on here running, or should I go thinner? What was recommend for this engine?
