you have a point adam however if the "protective coatings" (often AKA marketing) are in one reputable oil and not in the other, yet "required" wouldnt you expect to see multiple failures in that particular asset when using the oil lacking that particular additive?
Or one oil which over time provides significant and noticably better lifespans of engines?
This would be noticable especially in a situation of a large fleet of vehicles, machinery or vessels?
Personally as a marine engineer, I havent seen this from any of the major brands used in the past through our fleet of MTU, cats, wartsilas and cummins.
In some cases such as the old 2.8l hilux I believe your far better off using cheaper oil and change more frequently than trying to use synthetics etc and get a longer interval. Of course this isnt turbo'ed and hence oil is under lesser heat stress.
I would also expect that if the "protective coatings" are stripped away to any detriment, wouldnt they show up in an oil sample?
Without doubt Fuchs is a good brand though, and while I was fishing, cheaper than most. We used the same 15/40 in engines, gearb's, hydraulics and steering on suppliers recommendation. 100%.
