The Brad Penn boys are claiming Sterling has switched to their oil..

The last thing I want to partake in is a battle over which is best. If UAO's are to be meaningful you have to switch to an oil when the engine is new; do repeated samples every 20 hours for the life of the engine and have others do the same. We need apples to apples...same size and weight of boat...same degree of use...everything logged...then a mechanic inspection...it's too much work for us...

As far as I am concerned Sterling did it already. If they use M-1 now great if they switched they still found it to be a great oil in their machines. People switch for lots of reasons.

I already agreed to the fact that 20W-50 Kendall; Castrol and Exxon SuperFlow are great multi-vis oils. Their straight weight oils possibly even better at retaining Cst's...

Volvo-Penta is now offering synthetics..Illmor and Sterling and several others.

About 50% of offshore boaters use synthetic and 50% conventional.

V-Twin seems to give us stories of main bearings looking like new..over and over...UAO's are UAO's...teardown's where the autopsy results come into play

Everybody is right.

It's easier to get data from cars as most are run kinda of in the same routine manner. Offshore boat use can vary a lot from boat to boat. Same with motorcycles.

Everybody is entitled to their opinion...

Hmmm.. I saw Mike at SOTW, it seemed that they were still using Mobil 1 in July. Everyone is always changing. I wonder

They are always evaluating new products..a guy I know has 1059's was told..15w-50 M-1 is a good choice..that was in mid-July too.

Vegetable based engine oils...

Mobil-1 and iron in UAO's (test samples)...must read.

"You will find tha Mobil 1 will clean your system and the detergent/dispersant system will hold more particles in suspension (ie your normal oil may be dropping out wear metals in sludge at the bottom of the sump which is not seen in your oil sample). You should also remember that the wear metal analysis done by most UOA labs is based on ICP and the wear metal particles reported are less than 10 microns in size. Some of the iron you are seeing is in the form of metal soaps which will be more soluble in a good detergent/dispersant package.
Mobil did some engine tests switching from a mineral oil to Mobil 1 and saw increased wear metals in UOA. Engine strip down actually showed less wear in comparison to the mineral based engines"

SO it's saying iron in this oil is due to the chemistry holding it suspension to protect parts from wear. Other oils let it settle out...interesting theory..

Teardown not UAO's is where you see how an oil performs.

That's why I look at UAO's with a grain of salt...I have seen engines with no wear on UAO's look like chit when taken apart and vice versa..

Speaking of Vegetable based lubricants and this is somewhat off the subject. ExxonMobil has a full slate of vegetable based lubricants called EAL's or Environmental Awareness Lubricants.

Hydro,
How do you know so much of oils
Do you work in the industry?
