[quote name='Lynn E. Hanover' date='Jul 27 2005, 11:06 PM']The bearing area to load ratios are so good in the rotary that lubrication quality in normal use in not a factor. Almost anything will work....



Since one of the features of synthetic oils is resistance to heat breakdown, there is little chance that complete burning ever happens.



I use 40 Wt. Redline synthetic in the drysump tank and premix Redline synthetic 2 cycle oil as a premix at one ounce per gallon in 93 octane pump gas. Shifting at 9,600 RPM since 1980.

Wow Lynn, 40w with a drysump and pre-mixing sounds good. But it also sounds like a track car set up for warm weather. And you shifting points are just a bit higher than mine typically are.

Actually, If I had an NA car I'd probably stay with the mineral oil, and I wouldn't know a "bearing area to load ratio" if I ran over it. But with the turbos, synthetic's shear strength and resistance to heat breakdown is the attraction. The added expense is definitely an issue, but I'm just hoping to get a little more time out of my stock twins...trying to save up for a set of BNRs.

Articles about the Zinc and Phosphates, which are the components in oil that are supposed to provide the magic antiwear barrier. This is also known as ZDDP. You must understand that the type of Synthetic as a base oil comes in two types of defined parameters. One, which is defined by Mobile, Amsoil and Redline and those of Castrol.

However here is some reference material regarding the ZDDP additive as a nonfactor due to degradation by heat and usage. There is so much involved that we can read for ever but check out the last link.

But you guys may want to buy this! I think I will just cause.

I use Idemitsu 20W50.

Oil developed specifically for rotary engines.
