Never have tried it, but I have heard from jet-skiers and outboard guys that it is the "best" there is.

water cooled engines don't need the same protection as an air-cooled engine does....................I would take what those "guys" said with a grain of salt..........jet-skiers don't necessarily work on their machines,nor do "outboard guys"........................Remember,until something is proven;you're just being a ginuea pig,to the manufacturer's

I just checked out their website; I think it sounds like hog wash;I read the testimonial,and the guy says"I could not detect any noticeable wear"...............as soon as I read that;I knew it was HYPE...........then he goes on to say"There was hardly any oil anywere inside the engine,and yet it spun so easily"...........Any Good mechanic knows that ball bearings spin without drag....................then the clincher was the company says this is the best oil for ALL kinds of engines;motocross,atv;jet skis,outboards,etc.................when there's clearly a different rating for water cooled engines,and air cooled engines..............I don't buy it............

Jammer,

Since you are obviously the lubrication expert on this forum I suppose that you can answer my questions, right?

What validates your assumption that this statement "I could not detect any noticeable wear" is hype other than your kneejerk gut reaction? Did you correctly apply precision measuring instruments to the components in question and in fact prove there was wear?

Next question. In this statement "Any Good mechanic knows that ball bearings spin without drag" are you saying that ball bearings have no drag, or frictional losses whatsoever? That`s what your statement implies. Your statement also implies by extension that oil qualities such as viscosity, film thickness, and shear strength have no effect, good or bad, on the bearing`s inherent resistance to rolling because as you`ve stated "Any Good mechanic knows that ball bearings spin without drag". I`d like to see your answer to this question.

Third question. Although I agree that anyone making a statement that anything is "The best" is generally a huckster, your statement "when there's clearly a different rating for water cooled engines,and air cooled engines" apparently totally disregards the fact that an oil with higher standards of quality or a rating can infact be the better choice for both air cooled and liquid cooled engines. In other words, TCW-3 outboard oil will not be a good choice for an air cooled shifter cart engine because it won`t handle the higher temps that the cart engine normally sees but a good oil suitable for the cart engine will infact perform very well in a liquid cooled or boat engine in regard to low deposits, power output, and wear protection and might actually prove to be the best oil in a boat engine.

The way that you seem to shoot from the hip and make such strong and authoritative statements while turning a blind eye to obvious possibilities, even probabilities, makes you seem no more credible than the person who`s testimony that you have chosen to denigrate.

Ball bearings are also know as anti-frictional bearings: so for someone to say" they spun so easily" sounds funny to me;kind of like "the glass window broke so easily when a rock hit it"................have you ever seen a ball bearing spin hard before? If you have then you should know it was no good...............As far as wear goes you won't see noticable wear;you'll have to measure it to know how much wear is in fact taking place...........so that statement is hogwash too...........and last ;the best oil for air cooled motors won't burn completely in a lower temp. motor,(Watercooled)and will leave a residue behind,and gum up the piston,rings,etc. Pretty accurate shot Eh?
