my 2 cents worth. i run all my engines on motul grand prix 2t special comp oil at 80/1. full synthetic been running it for years on my airplanes and my weed eater and blower. one can serves them all. and all engines still look like they are new off the showroom floor. brisons for the a/c.. echo for the lawn equip. all engines were run at this ratio from day one. and run better with time. thats my combo and i am sticking with it.
RCIGN and silversurfer.... 2 people on here that know.....listen to them!!!!
