Bought this 98 GL ATX at 85K and love it. Uses no oil, runs great! (90K now) I can not find out what oil the previous owner used.
I have been using dino oil. Should I or should I not switch to a synthetic. What would the pros and cons be?
I have been told if you switch to Synthetic you should NEVER go back to dino oil,(RUINS SEALS). How true is this??
