Thanks for that!!
-Slightly lower fuel consumption.
-Engine slightly quieter.
-I monitored the carbon on the MAP sensor (I clean it every service) from the EGRs before 2SO and then after. Definitely less carbon after using 2SO.
-One unreal difference is the EGR's themselves - after not using 2SO for a while, my EGRs start to make a weird noise (when they're operating) that sounds like a bunch of cicadas has descended upon the engine. After about 1000km of driving with 2SO that noise mostly disappears. I admit I haven't used it for a little while and the noise has slowly returned. I will be getting back on it ASAP.
-Less smoke or no smoke when booting it. After not using it for a while and easy driving, my car characteristically will emit a cloud of black smoke upon booting it.
-If this is all the case, I assume there is a similar effect on the combustion chamber and turbine housing.
I saw a pic of a TDV6 stripped down by a guy in South Africa after it had spun a bearing. He had been using 2SO in his diesel - no carbon to be seen inside the cylinders!
It's well documented, try searching for 2 stroke oil or 2SO in diesel.
