Bought my first diesel, an 06 dodge 2500 mega cab. I love it so far! Have some questions; what oil, gear oil, what filters are recommended? And when should I change them? Also is there anything else i should do to it or anything else i need to know? My truck has just under 100k, completly stock as of now.

 

All I can say is 5000 miles. Learn it, Love it, live it. I dont care what you use or how long you have used it, change every 5000 miles. TRUST ME!!!
