Which Schaeffer oil is best to use in Harley Davidson Engines?


This is a queston we are always asked by our customers.  Hands down we recommend our V-Twin approvesd Schaeffer Harley Davidson engine oil#707 20W-50 racing oil.  This product has the extra zinc these Harley's need for the main rod bearings.  The oil is great for the seals to prevent leaks becasue of its conditioning package added to the oil.  Most Schaeffer customers can see aproximately a 9000 mile change interval no problem.

Here is a list of Harley engines:

ENGINE: Twin Cam, Evo, Ironhead, Sportster, V-Rod   

Recommendation: #707 Schaeffer Supreme V-Twin Synthetic Plus 20W-50

ENGINE: Flathead, Knucklehead, Panhead, Shovelhead 

Recommendations: #707 Schaeffer Supreme V-Twin Synthetic Plus 20W-50 or #110 Schaeffer Micron Moly Racing Oil SAE 50
