This is the oil we recommend for break in on all of our engines. It has Zinc (ZDDP) to help break in the cam and rings. Give your engine every chance to seat the rings and break it in properly.
**We’ve talked with the engineers over at Joe Gibbs and they recommend running it for up to 400 miles for break in. After that, stick with your normal oil change schedule. Mineral based oil only, remember? NEVER SYNTHETIC!
priced per quart (you’ll need between 4.5 to 5 quarts)
