The question was ask what oil would be the best!! I ran 1100+ HP on #3s and was doing the rebuilds,, even was making large shafts to upgrade the 3s&4s..
They would only live with amsoil!!! Not Mercs green crap and Royal Purple was worst!!
and Ran that Shadow Cat at 155-165!!

Here is some good info. I used to run Royal Purple in everything I had but then got sick of seeing it fail test after test.
Look at page 6 of this link.

This is what I run and will be running for the forseable future.

AMSOIL
500 hp or less,you can run anything,merc hi performance,what ever.500-750 hp,minimum of a synthetic and shorten change intervals.
Start making some hp (750 plus),AMSOIL severe gear,cryo and polish the gears,change it OFTEN (mainly to remove metal and debris). I tested ALOT using royal purple and I learned more than anything that it was less than ideal for high hp applications. I also found the thicker 75/140 royal purple seemed to slow boat down over the thinner stuff and gears failed just as fast although I never did a true back to back test on the same day as far as the speed difference,Smitty

AMSOIL makes a "marine gear lube", which is a 75/80w-90. Now, if you've got some rediculous HP, you can use the Severe Gear 75w-110, or Severe Gear 75w-140.

I like this stuff better than the Amsoil I used to use.

Picked up almost 100 rpm in back to back testing.

I just switched to Amsoil (http://www.amsoil.com/storefront/agm.aspx) from the Merc HP lube and I think that I lost some rpm/speed. Anyone know the viscosity difference between the merc lube and the Amsoil?

I have read the study that racerngr1 posted the link for. It is very informative. Short story:
1-Amsoil
2-Mobil 1
3-GM Synthetic Gear oil
I am running Mobil 1 as its great oil and easy to come by. And I had a couple cases lying around. I won't run merc hp as it is a conventional oil priced higher than a synthetic. What a rip. For the guys running real power, the best oil will be application specific. There is no one perfect oil for everyone.

What's nice about this product is it's designed to retain viscosity with up to 10% water contamination.
I'm an Amsoil dealer and can help purchase if need be.

Im interested in a 5gall pail, I guess they would drop ship from the closest warehouse to me?
