I'm due for my first oil change since I've had my truck, it is a '03 Ram with a 3.7 V-6. What grade, and quanity of oil does the truck take...and what Fram oil filter Number should I use? Thanks in advance.

The oil cap will specify grade of oil to use. Mine says 5w20. However, I personally use Penzioil Platnum 5W30. I think the fram # is 3600. However, I would recomend using the Bosch Premeum filter or the OEM Mopar filter. NAPA GOLD is also a really good filter. Im not knocking Frams, just do not personally like them.

How many Quarts does it take, I use Valvoline, is NAPA's oil any good, I don't want to go to two stores to get the stuff I need

I used 4.5 qts. It says 5 in the manual, but my needle stays put in the middle at 4.5.

yea im on my seocnd oil change and i have been puting 5 quarts....i decided to check the stick and it is reading almost a quarter passed the full mark...something for everyone to check..... im going to drain some out today

2Nd that Fram you paying for the name there lot better filter for the money Napa Gold is what I Use and Mobil One oil.

4.5 qts royal perpul mopar filter
