Air Cooled Engne Oils

[effvee]

Hi, I've read where there is a special oil for the seats/guided for the air cooled engine. Can some confirm this? Am I to understand the Castro oils and Havoline, Quarker State oil won't supply the needed lubrication?

I generally run bradpenn, royal purple, or royal purple max cycle motorcycle oil ($$$). There's also different additives from archoil or nanolube but I haven't had a chance to run those yet, though I do use archoil tungsten-disulphide grease in my assembly lube recipe.

Joe Gibbs make a great oil also. ANY engine that runs a flat tappet cam (non roller) you need zinc or ZDDP (zinc dialkyl dithio phosphate) to keep the lifters and cam lobes from wearing out too fast.

I've used the Brad Penn "Green Oil" for years, but have heard good things about the Joe Gibbs "Driven" oil. Some good reading -- http://lnengineering.com/resources/2...ut-motor-oils/

How much per quart? How about having your cam hardened.

Brad Penn is usually around $6-7 a quart in the parts stores/race shops. I get it thru a local oil distributor for $61 per case retail; ~$5 a quart. I'm running a standard Engle FK47 and SLR-treated German lifters. No issues.
