I got word the other day that an independent lab had tested most of the pre-packaged fuels out there and Stihl Moto-Mix was the only one that consistently tested at or above the listed octane rating. All of the others tested in the low to mid-80's. Stihl is supposedly putting up some big bucks to have this verified so they can use it in their advertising.
The Stihl MotoMix is based on an engineered fuel from Germany..It is shipped thru the port of Houston, Texas, trucked to Shreveport and canned by TruSouth Oil Company using Stihl's HP Ultra Oil.
Every shipping container of fuel is tested and Stihl's claims are based on fact, not fiction.
