Jens, as you may recall, Jan sells a certain synthetic. Perhaps that would account for a degree of bias

He sell the synt. oil but the oil can not use in all modelengines, some engines need castoroil.
Interest to learn out how many modelengines are damaged/worned out after Jan recommented the synt. oil as replace for castoroil in new and old engines with other material than common modelengines with modern material such as ABC and ball bearing.
Better to care the engine and follow instruction about fuel with castoroil or synt.oil recommented by modelengine factory and modelengineer or the warranty will be void in case the engine are damaged or worn out in short period cause wrong oil.
