1994/95 pickup help

[AKTikki]

I'm going to change the oil and put a clear line on the return line see what i can see. glow plugs are next week. trucks been sitting for a few years without running and the oil was changed but it sat for 2 years with fresh oil in it... if I have a lifter collapsed im going to throw some engine flush in before i do the change and add some lucas stabilizer to the new oil. I usually use delo 400 15-40. this thing has no leaks so I may look for a synthetic oil instead.. any advise as to which oils to stay away from? also i have seen diesel oils that are 5-40 synthetic... are these safe in the older diesels?

I've run it in mine. oil pressure is on the low side when hot at idle but not terribly so

I've run nothing but 5w30 Amsoil. diesel engine oil in all of mine. I am going to start running Mobile1 5W40 diesel engine oil, only because of the bargain prices I got on it. I will run it 10,000 miles and send samples to Blackstone.

If you really want to know how your engine oil &/or engine is doing send samples to Blackstone.

I would recommend the Amsoil 5w30 any day of the week

I agree get a 5w-40 Diesel oil for AlasKa which is a very cold area.

The store should have at least Mobil1 or Shell Rotella Synthetic.

Or Amsoil if you can get mail order in.
