Go to a library or find a a back issue of the March 2004 Trailer Boats
Magazine. They reported on and lab tested both specialty 4-stroke
outboard oils against ordinary car oils, including Mobil 1. The
results were suprising..

Other than paying off some NMMA bureaucrat for "certification", what's so
special about this wonderful lube oil, Bill?

This scam reminds me of the TC-W3 scams....





Hey Larry,

Welcome back. It's been quite a while since you've been active here. Hope
everything is OK with your organs, both musical and internal! How are things
up North in Charleston?

You will love the Trailer Boats oil article on the differences between the
expensive special 4-stroke lubes and the "el cheapo" car stuff. It's right
up your alley. Yamaha oil did the worst in the non-scientific rust test,
while Mobil 1 and the semi-synthetic Evinrude oil did the best. Followed by
Pennzoil 10W-30, Sierra, and Merc lubes. For anti-wear additives, once again
Pennzoil came out on top and was named "best buy". That is a $1.29 per quart
oil outperforming most $3.95 and up special lubes.

This oil test was done just before the NMMA 4 stroke specs came about. The
things that concern the motor companies was the lessening of anti-wear
additives in regular car oil due to EPA regs and that car oils do not have
to pass anti-rust, anti-foam, and fuel dilution tests.

The main thing is to change outboard oil often due to the motors environment
and high-speed rpms, compared to a car that loafs along at 2500 rpm @ 70
mph.
