stays mixed in gas, burns clean even in tight trails at low RPMs. I haven't fouled any plugs yet while using this oil. excellent lubrication and very little carbon deposits.
I have used klotz since I was 16 I'm now 38 still using is from weed Wacker to fourwheeler,and dirt bikes its the only kind I will ever use. I ran an 86 250r for 2 years on piston and rings, that says a lot right there
