I haven't read the replys so I apologize if I duplicate. Delo is formulated withe a lot of zinc just like motor oil for gas engines used to be. Zinc is important for engines with lifters sliding on cam lobes for wear as well as cylinder bores and wear in general.
When they developed true ester based synthetic oil it was far slipperier than that. However that is gone mostly and we ahve a higher refined dino oil labeled synthetic.
Diesel oil is formulated or was to adsorb or hold more ash, a good thing too.
Run Delo. If I were running a racing engine I would or a diesel. I considered switching to dino synthetic high dollar for the diesel.
However after all the lies about everything from EPA, Im trusing my logic until someone that knows more shows me better and run high zinc additive oi in the diesel.
