WASHINGTON - States no longer will have to add corn-based ethanol or MTBE to gasoline to fight pollution — a requirement that costs as much as 8 cents a gallon — under rules announced Wednesday by the Environmental Protection Agency.

Was it ever in marine gas?

Noticed Amsoil has 2 different Marine Gaer oil's, which one?

[QUOTE=Hydrocruiser]

Well I decided that if a company deserves your business they should make a product specific to marine use.

Does this mean that you wont run v-twin (motorcyle oil) in a hi-perf marine engine?

Kind of contradicts what the whole thread has been about

Limiting our choices to marine approved products would dramatically shorten this topic

An out-drive IMO is just a gearbox. If it is properly sealed then any good gear oil, or great gear oil like the HD Shockproof will work very well. If your drive is leaking the best "marine" oil in the world isn't going to avoid problems down the road.

A pressure and vacuum test annually + good gear oil is the best bet

Well I heard pressure and vaccuum testing can actually stress seals...only do it if you think you have a leak they tell me..

Amsoil Gear Lube in it's new formulation was out most of last season and it performed very well. Teagues gave it very high ratings when used in thier Platinum drives. It is a great product and the one I would personally go with. It's made for offshore applications and it will extend your drive's life.

-Excellent Gear and Bearing Protection even
when contaminated with 10% water
-Reduced Friction and Wear
-Rust and Corrosion Protection
-Long Seal Life ...additives for drive seal materials!
-Superior Foam Prevention

This plus a drive shower and you are good to go....Fred will give you a shower just ask him..

[QUOTE=Wobble]I see your point and it is well taken. It happens that motorcycle oils are the toughest beasts out there.

As far as out-drive lubes go there is more specific chemistry needed I feel for an outdrive vs. an axle. That plus testing. Auto lubes are not tested with water contamination or foaming as drives are much more punishing and subject to different environments and temperatures. The seals are also different.

The Mobil1 V-twin has lots of anti-corrosion agents and a load of ZDDP. It should be labeled "marine" as well as it is perfect for the application.

I was asked why additives such and Zinc..Phosphorous..Calcium..Antimony..Molybdenum etc are so important...

Well these agents are known as "Boundary Lubricants"...they say a picture is worth a thousand words...any questions??

How does Synergyn gear oil stack up? I did a search on this thread, but it only came up once.

No idea..
