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.

I also run the mystic snowmobile oil in my seadoo hx mixed 40/1 .

I've been using this in my 2005 Mercury 40 hp 3 cylinder engine for years. The engine still runs strong on my 13' Boston Whaler so I guess it's okay. Get it at WalMart.

Actually it does. You might not use your boat in the winter but lots of commercial guys do. In the marine construction and dredging business these work skiffs and other outboard powered small boats are used year round. Dredging season up here is November through March. I can tell you about working 18 hour days where I was running back and forth from land to barges in a skiff fixing crap where temperatures hit -20F degrees at night with 30 kt winds. Best part was everything was not only covered in ice but has a layer of oil and hydraulic fluid on top of that ice. Went in the drink a few times over the years as a result. Talk about miserable work, but the money was good primarily due to the insane amount of OT. 125 hour work weeks of hard labor in miserable conditions were pretty common in that job, and they had to pay us OT on the perdiam as well as our base pay rate so no one was complaining.
