Mobil Delvac
Re: Mobil Delvac
if you use Mobil Delvac i would use Mobil Delvac MX. the others are all CJ rated which is not all that great for older engines. its mineral oil not synthetic by the looks of it.
Re: Mobil Delvac
no problem running semi synthetic oil and provided its not burning oil a full synthetic is fine. however a 10k oil change is not advised unless its the manufactures interval. the only way i would be doing extended oil change intervals is if a bypass oil filter was fitted.
the other thing is not run CJ or any oil suitable for DPF's. these oils have the old good additives removed and replaced with others. the older motors work better with the older additives.
