[QUOTE="zukkev, post: 1419691, member: 17121"] Rotella 15w-40 Synth is a good oil, as long as it's rated for diesels....I have a 97 PSD, and use Mobil1 Delvac 15w-40HD with no issues at all... As for coolant, this yr uses standard green ethylene glycol coolant (Prestone or equivalent)...Just be sure to add something like Pencool (a nitrate additive) to help with keeping cavitation at bay....basically conditions the system & makes the coolant more slippery! :redneck: All pretty straight forward stuff...:awesomework: EDIT: One thing to keep in mind---just because you use synth oil, doesn't mean you can extend your oil service intervals...the oil is basically the heart of the fuel system, and undergoes a tremendous amt of strain as a result. Running extended service intervals thins the oil/ loses it's lubricating qualities, potentially causing galling of the injectors... Keep your service intervals at 3-4K MAX, and you should be good.:; [/QUOTE]
