Did I just waste 2 gallons of gas? Fleetwin oil mix.

[Britcheflee]

So does the following information taken from another site be followed for the fleetwin I have? Just put in 1 pint of 30 wt oil in the gas - should I have used the marine two stroke oil instead?

Oil - Oil Mix
Never, ever, use automotive oils in your air-cooled outboard. Yes I know the instruction decal says "automotive SAE 30" however today's automotive oils have additives that make them completely unacceptable. You should use the original recommended fuel mix ratio of 1/2pt of oil per gallon of gas but with modern TC air cooled 2-stroke oil. On my motors, I use 3/4pint of air-cooled 2-stroke oil per gallon of regular gas for added security. I've had very good luck with the Sthil brand of 2-stroke oil and Golden Spectro 2-stroke - this is the same stuff I use in my mopeds and yard equipment. People always ask me "do I really need to use so much oil" and the answer is always the same - YES!! Oil is still cheaper than parts or a new outboard: USE THE CORRECT 16:1 ratio and the correct type of oil - period!

It says for air cooled engines but concerned I used the wrong oil in the 7.5 fleetwin which says exactly that under the cowl.

I'm a bit confused. Did you mix car oil or did you mix air cooled two stroke oil?

Either way, just two gallons isn't going to kill your outboard. If it blows, it was going to blow anyway. But if you make a habit of it over a long time, it will cause excessive carbon build-up, piston ring sticking, and spark plug problems.

TC-W3 oil is engineered, tested and proven for outboards. Don't be trying to improve upon what's the best---use the right stuff.

Btw, your old Fleetwin probably already has the results of years of use of car oil or non-detergent oil in it. Take advantage of modern technology and don't be adding to it.

Use a 16:1 ratio (1/2 pint per gallon) for your motor. Use 2-stroke oil marked TCW-3! You could always "dilute" your earlier mix with properly mixed fuel.

This is really confusing. You say you have a Fleetwin, which is a water cooled, 7.5HP Evinrude twin. Then you talk about 16:1 oil ratios in air cooled 2 stroke engines.

None of the above is of any value for a water cooled, 7.5HP twin of unknown age.

Tell us the model number of your Fleetwin. Then maybe you can get some useful advice on fuel mix.

Sorry, I agree that was confusing. Basically I was asking if the information given regarding air cooled engines also pertains to water cooled engines - I think I might put that fuel aside and use it for cleaning stuff and start again with updated oil additive.


Thank you,

Thank you, will do.

Lee, on those older motors, non-detergent SAE-30 auto oil is fine to use. Is that what you mixed in? The multi-vis and detergent SAE-30 is not acceptable.
