Re: No-name brand 2.5 out-board
Jb if it is calling for 25:1 10w40 oil what do you think I should use with the tc-w3 oil?
If it's calling for 25:1 10w40 then use that. If you question it, contact the manufactorer or the ebay seller or any dealer of that particular product.
Nobody here is going to be an expert on chinese outboards.
But go with the outboard oil most likely a translation thingy 10/ 40 = tw-c3
It's tough to even call this thing an outboard. It's a motor that comes from china that has a shaft and propeller attached to it.
I wouldn't be surprised if it really did call for 10w40 though. Alot of jap/china motors run very hot, watercooled or not, TCW will cook off at higher temps, you'd be better off using chainsaw 2 stroke oil as a substitute than TCW oil. But if it calls for 1040, don't substitute.
