Also had problems trying to put diesel in the tank. Could not get fuel to flow smooth through the opening. kept shutting off. This is only the third time to put fuel in? Any history/help here?
15K is the upper limit for an oil change with Diesel. The solution is of course an oil analysis for the oil/filter combo you plan on using.
People will talk out their a**es (put two s letters in) about motor oil - but if you want THE TRUTH, for your diesel - have an oil analysis done.
