I have an 02 CTD with 33,000 miles. I've been running synthetic oil (Amsoil) in the motor for about 10,000 miles and am considering changing back to regular oil. Are there any issues (mechanically) in doing so??? I know that there are arguments for, and against, using synthetics, but I just need to know if I will damage anything by going back to regular oil.
Thanks,
Marek
