    They have these things called owners manuals, try reading it.

    I knew a guy that did that once, old farmer. Would but weedeaters at garage sales and use what life they had left in them. I actually watched him do this: Put a shot of motor oil in the fuel tank (not sure what weight) then topped the tank off with gas, put the cap on it and gave it a shake. Fired 'er up and trimmed away! I have NEVER had the guts to do that to an actual good 2 cycle engine, too valuable to me! If the one he had wasn't junk already I wondered how long it would last... If you have more than 5 bucks invested in your trimmer I'd advise using 2 cycle mix.

    What brand of motor oil did you have in mind?

    Back in the day before they had special 2 cycle oils, you would just mix in SAE 30 weight motor oil in with the gas. I had an old Homelite chainsaw that took a 16:1 mixture. Talk about smoky!! There's no way I would do that with a modern 2 cycle engine that I wanted to last for any length of time. Do what the manufacturer recommends.

    Yes, back in the day...1960's in Germany with my Uncle Sam...Had an Audi DKW car...3 cylinder/ 2 stroke. One quart of 30W oil and 5 gals gas and I was off for another couple of days of driving. It ran and ran for 2 years, then I sold it for $200...I paid $ 100 for it originally. NOW, I own Stihl and Redmax, all worth a lot more than that old car. Don't think I will ever resort to the old 30W oil trick again.

    Never thought of it - What is the make up of 2 cycle oil?

    I would assume with using regular motor oil, you will have a much higher carbon content, compared with 2-cycle mix. Which will lead to high carbon build up in your exhaust port and muffler. Also being of a much thicker consistency you might have more problems with the new carbs plugging their jets.
    Not to mention you would probably void any warranty if the unit is new.

    Nothing bad about good 30 wt. non detergent oil. it mixes fine, and I have not had one blow up yet. I normaly mix stronger than the manufacture says. 50 to one ,is not enough oil for any thing that runs that fast. The big boys tried 100 to one and are still paying for it.
    I usethis in all of my 2cyl. when needed, or if I have reg 2cyl I use it and or mix the mixes. If they have a slight blue haze after them you know they got oil to all the right places. 30wt. is fine as long as its non Detergent. Not going to stop now every thing I have still runs and has out lived all waranties. As far as mixing in the tank as was told,,, works,,, been there done that and still do once in the while in a pinch,, I would rather mix in a glass jug and then you can see whats in it at all times, then strain and put in clean plastic for later use.
