I've been adding 2 quarts of new motor oil to every tank full whenever possible for the last couple of months. I get about 1/2 mpg more out of ever tank than without the oil. Are there any negative effects to doing this? I get the oil for free, so it's not something that I could change buying.

 

I dont see anything wrong with it. I run 2-stroke in mine. Id probably run new oil if I could get it for free.
Hows the smoke factor?

 

It doesn't smoke any more than usual. Does anyone know if it is safe to run power steering fluid. I have a lot of that.

 

Only run Non-detergent with no additives.
