Two Stroke Oil Question

[thefasterfish]

Good Morning

I have a Mercury 97 1997 20hp that calls for TC-W3 2 stroke. Our outboard two Stroke in town has been pricey lately and saw that super snowmobile Castrol was on sale and TC-W3 approved. Just wanted to confirm if I could use the super snowmobile oil for the outboard gas mix.

Thank You

It'll work fine though they're not made for the same environment before someone on here tells me off.

Marine oil doesn't need to have the cold performance snowmobile oil has. Marine oil has a bit more corrosion inhibitors but I doubt you'll have any issue in the short term. Is there a canadian tire or walmart near you? I buy gallon jugs of tcw3 at walmart to use in my ope and I've had no issue with it.

Should work just fine. Not sure if you have access to Mystik oil but I have found it to be excellent in 2S applications and they usually have a rebate going to make it even cheaper.

If you were in the US , I'd say Supertech TCW-3 is an option . There's also a name brand one (I think Pennzoil?) for nearly the same price.

If it's TC-W3 rated that will be the right stuff.

I ran snowmobile oil in my old Seadoo 800 2 stroke for years. One jug for 2 machines, no issues. And the Klotz smells good.
Snowmobile oil has a low temp pour point for injector use, only difference. I used TCW oil in older premix snowmobiles also since they were not injected so no injector issues in the cold and no engine issues.
