Two Stroke Oil

[VicS]

No, we used proper 2t oil even in the 60s. As Vic says - use the makers specified oils.

Unless you have an old 10:1 Seagull of course! :-(

The current recommendation for Seagulls is to use TCW3 !

No, we used proper 2t oil even in the 60s. The difference between m/cycle oil and o/b is the combustion and operating temp of the engine. Most water and air cooled outboards are fairly low revving and run fairly cool. Bike engines can rev up to three times the speed and run much hotter. Their oils are designed to work at higher extremes. Using the wrong oil either way can result in incorrect burning and ashing fouling the plug, which stops the engine, sometimes quite quickly. It may also not provide the right level of lubrication. 2 strokes always run on the edge of oil starvation. As Vic says - use the makers specified oils.

Air cooled outboards do run pretty hot ! So hence my original question. But I will stick with water cooled outboard oil as that seems the consensus

Yes, sorry about that.

I had an yamaha RD350LC motorbike back in the 1980s. That was a water cooled 2 stroke.

nice bike, I had suzuki's both two strokes the 250 was fun but the 380 gt was omg I wonder if the smoke screen would blur out modern day speed traps
