The 50:1 ratio is correct, nikmisko.

Any outboard oil rated TC-W3 will work just fine. I use WalMart Supertech.

If you are willing to spend more money (a lot more) to get less smoke, pollution and carbon buildup, get a full synthetic outboard oil (still needs the TC-W3 rating).

Thank you very much JB

I definitely look for a cheaper choice but i don't like to shop at wal-mart and support the corruption but definitely will look around to get a good oil for decent price . Thank you

It might sound silly but does it make a difference what octane of gas i use? once again. Thanks

What octane you use makes little difference except to your wallet.

In 1970 the preferred gas was 80 octane AMOCO "white".

FYI, I was in Academy the other day and they had a TC-W3 2-stroke oil for ~$18 a gallon. Not bad compared to $30 for Evinrude branded. Another option is some boating repair shops sell bulk oil (usually BYOJ - Bring Your Own Jug). There's a Suzuki shop near me that sells Suzuki's TC-W3 oil, bulk, for ~$22 a gallon.
