Wich oil do i use or addtives?

[workaholic]

I have a 1981 Merc 200hp outboard that I just recently purchased. I filled the fuel tank mixed 50:1 cheapy oil.

Wich oil would yous suggest, also how about using additives to "revive" the performance a little.

Thanks

Re: Wich oil do i use or addtives?

Any outboard oil that is rated TC-W3 will do just fine, Eric. I use Wal Mart's SuperTech so I won't have to pay for somebody's advertising and promotion of oil that is no better.

Synthetic TC-W3 oil will give you less smoke, pollution and carbon buildup but at a lot more cost.

The only additive I would recommend is Seafoam, but it is to help keep your engine clean. It does nothing for performance.

Any additives for " improving " compression that anyone know of that works with 2 strokes..

Thanks

Re: Wich oil do i use or addtives?

If carbon builds up on the rings it can cause some compression issue and Seaform may help and certainly won't hurt .... but if you have a cylinder that's down over 10% from the others you have other issues that no additive can fix

Also if you aren't going to use the fuel within two weeks some Stabil would be a good idea, if you are one of the unfortunate ones that can only buy 10% ethanol then get the Marine Stabil and use it for every fill up so the ethanol doesn't separate from the gasoline which can/will happen in a highl moisture application like boats
