Re: 100:1 Mix
Doggone if my CAG engine just does not like Opti-2. Ran it for the first time with the new piston and cylinder and it overheated again at 36:1, but did not seize or score. Could not restart until it cooled off. Called Duane at Dax and he said to go with Valvoline at 20:1. So no more Opti for this engine. Have not run it yet at that ratio. Been too busy with the engine rebuild on my 1990 Geo Metro.
