Synthetic oil just means it is man made, so there is going to be all sorts of different compounds. A splash fed engine relies on the oil compound sticking and working it's way into the moving parts.

As I understand it modern car based synthetics simply fall off before they get this far. Ironically the degoverned engines probably mean the oil works better than in a standard engine, because it's thrown around more.

Regarding Dyno results differing from those seen on the track. The comment about a certain pair of engines coming good at a certain track is illuminating and shows that the Dyno results are not being analysed properly, or at least used to their potential. You will hear people talking about peak power and then others saying that only area under the curve gives a good comparison. In reality though both of these are only reading the results 2 dimensionally, the only way to use Dyno results conclusively is to compare the whole trace with the rpm trace from the track you are running at.

Sounds more complicated than it is and certainly when you have gearing to consider as well, you could spend an unessasary amount of time just choosing an engine. However when we ran in a class with fixed gearing, I had 4 good engines and for each I printed the power curve on a card and laminated it. From the Mychron, after only a couple of sessions it was quite easy to work out where the engine spent most of its's time and choose an engine apropriately.
