I just had a 351/408 stroker built by Keith Craft. They recommend Joe Gibbs Driven HR 10-30W As a matter of fact they require I use it to maintain their warranty

What kind of oil should I use?


This is a fantastic article written by Dr. A. E. Haas at Ferrarichat.com. The poster has edited most of the spelling errors and grammar, and shortened the article to just the first four chapters/lessons.

Wow, impressive! I was concerned about cold start. So guess I will give 10 or 15W-40 a try then see what oil pressures it gets me.

Now I only need to find an oil in that class with high ZDDP content, available in Europe. AAAAAAAAAHHHHH

someone stated in another thread that an engine with a main bearing clearance of .0027 or more needs heavier weight oil.

Same here on my KC FE - however, when I commented about the 15 psi at hot idle they said I could switch to the Joe Gibbs HR 20W-50 to increase it. At first I was planning to but after some further thinking I may stay with the 10W-30 and watch my idle pressure. I wish Joe Gibbs made a 10W-40 HR oil.

Most of our cars are kept in garages and don't see sub-freezing temperatures (some of you Northerners may be an exception). My garage doesn't typically see anything below about 55 deg in the winter. So, I'm not sure the concern about using a 0 or 5 winter weight oil in these cars is as great as for a daily driver that may be parked outside overnight.
