Re: Oil question
I found this in article concerning ultra light air craft ;
" So, how do some oils claim to be multi-purpose or formulated for water and air-cooled engines? These oils have usually been formulated to meet the National Marine Manufacturers Association (N M MA) TC-WI I TM or TC-W3 TM specification. These specifications require the oils be tested under rigorous test conditions. An air-cooled engine test is part of these requirements."
Now, not taking it into direct context, what I have is not a multi purpose0, but considering specification requirements, it doesn't sound as if it will do me any harm ?
