Synthetic is great for Rollers but it can wipe a flat tappet.





Use the right oil with the proper additives, valve train set up correctly and break it in right and you won't have a problem. I've done it for many years.

FWIW, I run their Dominator 5w-20 all the time. I'm hoping to swap the engine out soon after about 4 season to play it safe because of fatigue concerns, not wear. Oil pressure might be considered a little high, around 70+ through the lights. But me and the engine are happy.
