Which 2-stroke oil...

... for Yamaha 90?

I have always used Quicksilver but have 5 litres of Comma 2-stroke oil which is labelled:

"Low ash, monograde oil for 2 stoke petrol engines (motorcycles, mopeds, cars, chain saws, lawnmowers and small air cooled outboards etc.)
Helps prevent plug whiskering.

Service Classification: API TC CEC: TSC-3 SAE30"

Is this OK to use or should I stick with Quicksilver?

Stick with what.....

......you know. Although Quicksilver ain't cheap, it's bloody good stuff. How much is the other stuff ? I'm currently paying £19.99 for 5 litres although I've seen it at £21.99.

I have tried the comma two stroke oil and i have to say it aint as good as Quicksilver. I found that the performance was not as good and the plugs did foul up alot quicker so my conclusion is stick with the Quicksilver.

Plus

If you read the quicksilver packaging it says in is combustable which i asume it does not just lubricate it has some additive to make it burn with the petrol!

Don't use it... it's not the correct stuff. Use only TCW-3 spec oil in marine outboards. I'm told that the Comma stuff will burn at a higher temperature.

Good point but remember a lot of the TCW-3 spec is for environmental reasons for boats using inland waters!

Motorcycle 2 strokes rev a lot higher than outboards and are higher tuned.
They do not use inferior oil, I would have thought the only difference would be for emmissions. With the exhaust exiting in the water the residue left from the oil is probably the difference.

If you wanted to save money then I would buy shell Nautilus oil. Comma oil isn't famous in the Marine industry and you should use the right spec oil.

how much did your motor cost/is it worth?.

If you really want to save money and on the basis that all oil burns then I have a couple of thousand litres of Derv ,,,,come and help yourself to a Gallon or three!

RIBase
OIl for Outboards is TCW-3

As it says above - the correct oil for conventional two stroke outboards is TCW-3. I believe that the W stands for water cooled. A water cooled engine will run much cooler than an air cooled engine and needs a different oil. This is probably to reduce plug fouling and gumming up of other parts but I am only assuming this.

Have just bought some Esso TCW-3 for £2.50 per litre in my local chandlery. However it is green rather than blue - does this mean that I will get green smoke?

Thanks for replies. I'm not looking to save money. Just happened to inherit this oil from a friend who I think used it for go-kart engines. I was a bit dubious about using it - thus this thread. Based on above, I'll stick with the Quicksilver.
