Ram Diesel Problems

This link has a diagram that might help.

 

im new to diesels i just bought mine its a 1998 5.9L 12 valve how long can you go with an oil change. when i bought it there wasnt a book for it.

 

I go 5k at most

 

My habit is 3K-ish. A great many will run synthetic oil for really long intervals, while changing the filter and replacing that volume about every 3k.

Total volume is about 10 liters, or 11quarts. I once brain-cramped the whole 3 gallons into the crank-case with no obvious ill effect, but a proper fill is only 11, not 12, quarts.
