Several hundred gallons and he is complaining?? Im sorry but thats not bad to get that much out of an engine. Its not the oils fault on that engine. As far as the others go, it sounds like I am going to stick with Penzoil.

Thats my friends DA100 after several hundred gallons of Amsoil at 80:1
The engine was low on compression. Spool up was slow. The rings were both stuck. Plenty of HARD black carbon build up on the pistons and in the combustion chamber.
We cleaned the ring grooves slightly and installed new rings. Put it back together and broke the rings in with 2 gallons of Husqvarna oil at 32:1.
The jury is still out on weather or not it will help the engine. It's coming alive and spool up is quicker now. It'll probably be run on Red Line or Penzoil at 50:1 from now on.
