Fossil oil is fossil oil and synthetic oil is synthetic oil...so all oils aren't the same. TCW3 is your most important requirement due to additives for moisture. Personally the penzoil synthetic blend gives me that warm and fuzzy feeling (here comes the perverse jokes lol) and hasn't let me down yet, and it's reasonably cheap.

Don't use walmart brand oil.Why do you think it's cheeper ? Use pennsoil/Valveoline/Quicksilver anything but walmart oil. I'm a certified heavy equipment mechanic and I know all oil is not the same............

Can you explain that a bit more? I will only use Castor927 in my ski. Well, the 701 anyway. The 650 gets SuperTech. The quicker it blows up the quicker I can put a 701 in there...

Castor927 is not TCW3, but it is biodegradable. I always assumed that the TCW3 rating had more to do with controlling water pollution than it did marine engine protection, but I've got nothing to back that up...

Really? I guess you don't work on 2-strokes so you are forgiven in advance...

Walmart oil burnes up in the combustion process and does'nt lube the engine properly and you will burn your engine up.

By the time the oil is burning in the combustion chamber it has ALREADY DONE IT'S JOB. ALL 2 stroke oils burn up in the combustion process (why do you think you have to add oil to EACH tank of gas?). The oil comes in with the fuel and air through the carburetors. It passes THROUGH the crankcase and lubricates the bottom end before being pushed into the cylinders through the transfer ports. Then it gets burned up and blown out the exhaust.

Not all oil is the same quality, but WalMart oil is TCW3 rated. If your ski is close to stock and not running on the ragged edge then feel free to save a few bucks.

Who has the oil sampling/testing hook ups? We should send in samples of popular 2 stroke oils and get hard scientific evidence for ourselves.

I did some checking and found that as usual i was wrong...

"

The standards most used in this country are the National Marine Manufacturers Association (NMMATCW3) standard and the American Petroleum Institute (API API-TC) standard. Both of these standards address the oil ability to prevent wear, keep the engine clean and biodegradability. Since these standards were written for different types of 2-stroke engines it stands to reason these standards would be different. Hence, the oils developed from these standards would also be different. The NMMA TCW3 standard was designed by the various manufacturers of outboard motors (Mercury, OMC, Yamaha etc.). These manufacturers so not utilize power valves, limit their max rpms to about 6800 and have excessive cooking capacity. They also must be able to operate at lower rpms for long periods of time without oil fouling the spark plugs.?"

found that on "bobistheoilguy.com"

true... but synthetic is still different than non synthetic. I still say that all non-synthetic is basically the same. I'd assume that all synthetics are basically the same also.

actually syntheitcs take all different forms
mineral oils are just refined- seperated using heat in a distillation column
to set grades of fuels/lubes then additives like detergents are added
synthetic are mineral oil run through chemical reactors
to form different molecules
these molecules are as different as lubes, nylon, rayon, plastics, synthetic gasses, etc
slick 50 is a synthetic that incorporates a part of the teflon molecule for lubricity
just stick to TCW-3 for your 2 smoke application and it is all good!!!!
