Hybrid synthetics/Dino oil may help the longevity of the cone clutches but full synthetics may protect the gears better. I would rather rebuild a cone clutch that have gears implode. 
I just had a Shelby rear end customized by a shop that specializes in drag race 9 inch rear ends and his warranty is voided if you don't use Torco GL5 mineral oil.

I don't know the asnwer to what Teague uses. The Amsoil tech guys says he uses the Marine Gear Lube and the "People who have talked to Teague" says Severe gear. They are both good products.

I now prefer the M1 75/140, readily available and no apparent artificial coloring.

I do not mind putting up with the messy nature (definately messy) and slow drain rate (I use a vacuum pump system) as long as it provides the best protection and does not cause performance problems elsewhere as in the clutch cone issue implied herein regarding other syn lubes.

Has anyone got any information or test results back on Mercury's new full 20-40 synthetic oil? I seen some on the shelf the other day at a Merc, service center. The only thing that concerned me about it, was the claims I read on the quart of oil. It said something to the effect of being formulated to protect the new catalyst systems ( emission) of there new engines. Isn't that the reason the new automotive engine oils don't protect as well because there lacking anti wear additives ( zinc) etc. because of damaging emission controls?
