Last time we spoke Dave advised me that the oil injection system really doesn't "inject" the oil in the sense that it enters the combustion chamber as a mist or stream, rather that it causes a droplet of the oil to emerge from the injection port and then be wiped away by the apex seal. FWIW. I've had my disagreements with Dave Atkins, but when it comes to hands on experience with these engines (racing, flying and otherwise), you'd be had pressed to find someone with more (well; maybe Leon, but I don't know his experience). I'll accept his word that carbon buildup problems mainly occur in cars where cheap oil is used, and/or not changed regularly. His experience shows that injecting engine oil using high quality synthetic (Amsoil) with our duty cycle es no problema. Al
