So my seadoo 800 calls for an api tc jaso fd oil. They say not to use tcw3, because it can’t hold up to the heat. Klotz skicraft says it’s a tcw3 and jaso fd oil. Can I use that? It also says safe for rave valves.

Klotz is fine. Oil specs are for big oil companies so they can produce the cheapest possible product that works in a particular application. Klotz and every one else who blends "racing" oil just mixes up a batch of who knows what, and puts their sticker on the bottle. Of course their products always "meet or exceed" all past and future specs. Some of them are actually very good, others questionable at best. People often buy more expensive products base on advertising alone.

I was running 2t redline in my rotax 447 powered airplane. I was informed by numerous a&p that I should switch to a tcw3. Because it would handle the same heat, but provide much better corrosion protection. These are air cooled engines. So I'm doubting your water cooled engine is seeing more severe usage.

They recommended wal mart super tec. Or amsoil 100:1. No joke. And that is what everyone I fly with uses to lubricate the engine that is holding their life in the air. They have the money to buy any oil they want.

After I heard that. I stopped believing all the hype about this oil vs that oil. It's all a grain of sand in dubai.

Thanks everyone. I called klotz. They said their tcw3 also meets jaso fd, and will hold up to the heat no problem. And I’m running klotz for the smell too.

Big oil companies made aircooled spec oils in the past. They may still but its getting difficult to find. One really good oil that has aircooled detergent and still works well in PWC is Maxima Super M.

Always fun oil debates.

Your numerus A&P's seem to contradict the Rotax engineers...

"Our Rotax aircraft engines operated at high load, high rpm and high piston temperature for prolonged periods. For our application the correct oil specified is API -TC (low ash) rated oil, period! This applies to to the aircooled (503) as well liquid cooled (582) aircraft engines equally.

A boat or watercraft engine is cooled by cool lake water and this engine application experiences much lower piston temperatures. These craft use TC-W3 rated oil.

A boats engines exhaust exits under the surface of the water. This reduces the exhaust sound level, however the products of combustion enter the water directly. TC-W3, (ashless boat oil) has an additive (detergent) package made up of organic substances to reduce water pollution. TC-W3 organic additive package will not withstand the much higher piston area temperatures our Rotax aircraft engine experience.

Our API-TC (low ash) oil for use in our aircraft Rotax aircraft engines has a additive (detergent) package made up of metallic substances (heavy metals) . This additive package is what allows piston area protection at much higher temperatures.

True API-TC oil users make up up a small percentage of the market, so oil companies have reformulated TC-W boat oil to also pass the minimum API-TC test standards. This fits all engines oil blend is like a “one size fits all” piece of clothing. I believe this dual purpose oil blend must contain the low temperature operation organic additive package or it couldn’t be used in a watercraft.

I would recommend you use only a specified standalone API-TC oil to protect your Rotax aircraft engine. Rotax has documents referring to correct operating fluids, including two stroke oil. "

I love this site

Rotax doesn't even recommend their engines be used in airplanes. Rotax techs recommend amsoil. Or super tec. I've talked to many. You can fly whatever you like. Or type at your keyboard.

Any aircraft powered by a Rotax 447, that was registered, would be touched by an a&p. Lol

Your oil sucks. Mines better

Two stroke oil is often application specific so use whatever is working for you. What I mean is I have tested several types and brands in several types of engines and the results were often puzzling. Mainly with the way some would be perfectly clean in one application and really gunk up a piston and exhaust in another. Keep an opened mind and do a lot of testing!
