Well I guess I will jump in and hit the dead horse too. I just bought a new Dodge Ram 1500 extended cab truck and it has the 5.7L Hemi engine. I have done a search and havent found much info on what seems to work well or is recommended. I changed the factory fill at 450 miles with a mopar filter and Penzoil 5W30. I am right at 1000 miles now and am preparing to make my 2nd breakin change. Here in Balto the temps are starting to climb and I will be pulling a small travel trailer this summer (3000 lbs). I was going to change to a Pulolator filter and Chevron Supream 10W30 because of the towing and heat. After finding this board though I am thinking of just going to Mobil 1.
I might mention that this is mostly a weekend and vacation driver so I change the oil every 4 mos regaurdless of milage which is usually less than 2000 miles. I am more concerned with preventing sludge and varnish and protection on startup than with cost of oil. Given this is a fairly high compresion engine at 345 hp 345 cu/in, what would you reccomend.
Thanks
Sam
