Outboard oil??

7 posts in this topic

I have a question. I have a 96 90hp evenrude. my question is this. Do I have to use the omc oil or can I use the oil sold at wal mart?I think if it has tw-3 it is ok to use. Am I right or should I continue useing the omc oil. Don't want to damage thie engine.

thanks Bruce. I think I'll stay with omc oil, not worth blowing a motor to save a few bucks

I used tcw 3 for years and finally blew the motor. Stuck a ring I believe it was from excessive carbon deposits after tearing into it. I would use premium non ethanol fuel and amsoil to help prevent this. Also make sure you decarb the motor at least once a year. The amsoil will help get rid of the smokescreen the old evinrudes are famous for.

FWIW, the Merc Quicksilver PRemium Plus oil contains small amounts of what merc calls QucikClean (I think that is is it, their decarboning agent) so you never really need to do a big "treatment" of decarboning. Otherwise isn't the Yammie product called RingFree that is a real popular product, that I think many people use.

Our 82 merc 50hp has only been fogged like twice for storage, we stopped doing it cause it was always a bear in the spring to start after fogging, but we only use Premium Plus and it is running strong after many hours - now it usually only gets used a lot in spring and then a ton during duck hunting season. And we have never really done a "decarboning" except using Prem. Plus... Not sure if that is advised, but that 25 yo motor is still as strong and reliable as when it was new.
