Two stroke oil

Hi
I am in the process of buying what looks like a nice 5hp tohatsu 2 smoke from fellow rib member mattwarner, my question is I have a stilh chain saw and hedge cutter which are also 2 strokes, can I use the stilh oil in the tohatsu ?,if not could I use the marine oil in the garden tools, or should I just keep separate supplies
Thanks for any advice
Regards
Mick

No, keep them separate - marine oil is a different formula as the two engines are designed to run at very different temperatures.

What Max said.

The stilh oil is for air cooled engines that burn at a much higher temperature. If you put that in the outboard it'll gunk everything up. Buy proper marine 2 stroke oil and keep everything separate.

Curiously, does anyone know about the very small air cooled outboards? Do they use normal marine 2 stroke oil? or do they burn the higher temp oil? I've never owned one...

>>> does anyone know about the very small air cooled outboards

20yrs ago I owned a 3.5hp air cooled Yamaha version of this...

On the theory it ran more like a chain saw (re temp) I used chain saw 2-stroke oil. Noisy thing but very reliable.

That makes sense about the oil.
I guess the water cooling acts as a noise absorbing jacket.

Hope your happy with the outboard Mick, good to meet you and wish you many happy hours with it! Had I read this beforehand I would have given you one of my spares that I only use for pre-mix.


As said stick to a good quality TCW3 (I only use Quicksilver)

Very happy the the tohatsu, when I had to give up boating I had a yam 40hp two stroke, on returning I found 2 strokes were now banned having tried a Honda 2.3, Suzuki 6 hp, mariner 6hp 4 strokes I am over the moon to have a motor that smells like an outboard, sounds like an outboard and hopefully goes a lot better than any of the 4 strokes I have tried, only wishing now I still had that yam 40, loved that motor
