Synthetic Oil

Synthetic oil ?

I seem to have a different opinion to other users. A buddy spoke about the positive benefits of synthetic oil in his aeroplane so I tried it in mine. The oil remained clean and after quite a number of hours I realised it wasn’t scavenging the carbon. I returned to the usual detergent oil and it got very black very quickly. I continued to change frequently until normality returned.
It is for this reason I never used it again. Has the composition changed? Or am I being obstinate? I have an open mind to logical criticism and positive suggestion.
