How Long Can Syn Stay Good In A Dd Piston Car?
#3
is it the original oil? Cause if it is you should have changed it aftert the engine broke in.. If not.. It can be left in there but it is just better to change every 3k to 5k miles.. Just as preventative maintenece..

Synthetic oils can last MUCH longer then that, the filter on the other hand needs changing regardless.
We used to change filters every 2500 miles and change the oil every 20,000 miles, using Amsoil and one of those cars had over 500,000 miles on it when it was retired from Limo use and still runs today.
Change the filter, then top off the oil a bit to compensate for any loss of oil.
