Don't use outboard engine oil in any 2 stroke air cooled hand tools. They don't last long if you do, as the repair man at the tool shop said as he handed me back my multi tool that had seized.😳

This is for the reason already explained that the air cooled tool runs much hotter.


last year I ran my Tohatsu 9.8 exclusively on Aspen 2T it seemed very happy.

Fed up with stripping outboard carbs and putting them in the ultrasonic cleaner.
Should you not be using the Aspen 4 stroke fuel and add TWC3 oil for the outboard?

Indeed it has !
It’s to do with the male alter ego of “ I don’t need to read the manual “
.. and the confident belief that I - that is ME, at home in the gravel - am smarter than the thousands of experienced engineers and scientists working for the car manufacturers.
What they have spent tens of thousands of hours developing, I can do better from my armchair.

Go figure.

Or you can just sit in your armchair, Spout or copy and paste a little theory or go out there and get you hands dirty and realise that much of what those corporate Engineers spout is driven my money, Profit and Marketing

When you use your natural scepticism, the marketing blurb quickly gets sorted out. It's often obvious.

The talk was about oil and I have trouble understanding why people don't just buy a product that meets or exceeds the manufacturer's recommendations.
Like using TCW3 when this is recommended.

Whether the brand is known or unknown is not important if it meets the certification.
All IMO, of course

If someone personally has more confidence in a particular brand, they can buy that. He who decides pays - and vice versa.

Hi,

I think manufacturers of two-stroke outboard engines almost always recommend using two-stroke oil specifically designed for outboard engines.

The outboard is typically cooled by water that is sucked from the water, which keeps the engine operating temperature relatively low even at heavier loads.

In this case, the oil must be designed so that it burns particularly cleanly and without cremation at low temperatures.

Maybe full shyntetic 2 stroke oil burn nice vs dino oil.

Many yrs ago I had a Mercury 50 OB on a Broom Scorpio, I bought a 25ltr drum of quicksilver 2stroke and put it into 1tr bottles. I had two tanks and would add the oil when filling.
I was towing the boat for a Sunday out, stopped at a garage about 50miles and realised I forgot the oil,anyway I thought I'll put a good 2stroke oil in and it wont hurt this once....WRONG..pistons melted in the bore....

I don't understand what the reason or justification would be for not using the TCW3 oil that has been certified by the manufacturers for use in outboard engines?

For me, it's a crazy waste of money to have to pay for a new litre of e.g. Quicksilver 2-stroke every two or three years. I just don't get nearly enough use from the engine to need that much 2-stroke oil, which is reckoned not to last once opened.

I found this thread after looking for smaller containers of 2-st oil. I accept that it's necessary not to use the non-outboard variety, but why isn't the right stuff available in much smaller sealed quantities? Or if it is, where?

I haven't actually used this but I would give it a try. It does say outboard on the bottle?

Thanks, but it's still far more oil than I need at 50:1.

If they sold 125ml or 250ml cans, I'd buy straightaway. A quarter-litre would easily lube two season's worth of fuel. Not purely a matter of cost, just a crazy waste of oil.
