I just had to reply, even if I'm barely a believer in it. But... I gotta say been using Mystic 2 stroke Synthetic for 20+ years in Saws, motorcycles, outboards, weedwhackers and as a Diesel additive on older diesel engines Mainly to protect the Injection pump from low sulfur fuel. When my two gallon can of 32/1 mix gets old- 60-90 days, guess where that gas goes. My experience with 2 strokes is This oil is the best and cheap too. High output engines, no ring sticking and clean inside. Diesel pump experience is A few hundred thousand miles, no failures at around 100-150/1. Inside of the 2 stroke engines are very nice, bearings wearing extremely well, combustion chambers and exhaust ports no carbon buildup, only an occaisional light cleaning of the exhaust screen. (small amount of ash. )Thats why it's not TCW2/3. But it is JASO FD, which is a way higher standard, and nearly smokeless. Not too many Oils meet JASO FD, Most are repackaged Mystic.
