    Does it hurt anything if I use my mixed oil/gas for my 4 cycle engines as well as my 2 cycle?

    Probabally not.May make them smoke some. But why would you want to waste expensive 2 cycle oil?

    The main problem I'd think you'll have is detonation.. and deposits, and a lot lighter pocket book...You are asking us because you ran out of straight gas in the middle of a job and just wanted to make sure you didn't hurt the motor, right?? If so, I'm sure you'll be fine, I've done that in a pinch myself, with no ill effects.

    We have been selling commercial mowers for 19 years and have not allowed straight gas in the shop.

    Everything that burns gas has always been serviced with mixed gas for 19 years with no problems.

    We use only Amoco (BP now) 89 octane and Shindaiwa or Stihl oil.

    For several years we used Optimol 100-1 in all new equipment (2 & 4 cycle) and everything we serviced in our shop. I'm not sure why we changed to 50-1.

    If your help isn't any smarter than that, maybe you should consider new help. Color code the gas tanks...maybe that will help or don't carry any straight gas on the trailer.
