5.7 Hemi 0W30 GC

I ran 375-425 HP Chevy engines at the drag strip and on the street for quite a few years. The Hemi engine while not as powerful is of the same basic build and design. Never ran into anyone running a light viscosity oil (5w20)then or now. Guess I'm just old school when it comes to oil viscosity. I'm still not convinced that it (5w20) serves any purpose other than slightly better gas mileage. And possibly less protection in some applications.
Changed my differential fluid out at 18,000 and other than some discoloration it looked pretty good. The gear housing was clean, hardly any signs of wear.
I use the K&N filter because I have always had good results and it decreases the frequency of filter changes, drop it in and clean every 50,000.
Running the Redline I'm going to about 4500 on the OCI. I must agree $7.95 is alot, I'm looking for other options as we speak. But I'll probably never go back to conventional oil...to many good syn's for less than $5.00 a qt.

Just put in MC 5W-20 in my '03 2500 Ram last week. I will do a used oil analysis at around the 5K mark. Looking foward to seeing how this thin oil will do. I went thin this time becasue of the weather here in Indiana, and I will not be towing nearly as much during the winter months. (5th Wheel in storage)
The last oil I had in the HEMI was Mobil 1 0W-40. Had to use 3/4 Qt of Mobil 1 5W-40 make-up oil over the 5500 hard miles I ran it. I did not do a used oil analysis because of the make-up oil. By changing the oil type, the used oil analysis would not reflect its' true #s.
I did a lot of heavy towing and a lot of Hyway driving in the hot Gulf Shores area. As such, I don't think that < 1Qt of makup oil was that bad. I run Shell gas too switching between reg and V-power. I use V-power when I tow.
I get a true 12.6 MPG. For a 3/4 ton, Quad cab 4X4, I think that's OK. At 55 MPH, I can get up to 22 MPG. After hitting 60 MPH, the MPG goes south VERY fast.
Hope Motorcraft come thur.. I also use it in my 03 Sable and 89 Honda..

Buster,according to the mech at my local dealer there was a bad production run of valve springs for the Hemi. He was pretty vague about it but said they only had (1) out of the dozens of Hemi's they have sold that broke a spring. The production run was probably in late 2002 or early 03). The dealer mech said they haven't been inside a Hemi engine other than the one mentioned. Said they have had no problems with the 545rfe trans. I've only read of one 2004 that broke a spring, all others were 03's. (Hopefully there ain't none in the late 04's)
Dodge really hammered this engine during testing. IMO it's going to prove to be pretty bulletproof, got my fingers crossed anyway.
I went from Redline 5w30 to Mobil 1 10w30 on the last change(Redline oil sample got contaminated, so no UOA)and by a "seat of the pants feel" the Hemi loves it. Still got a case or so of GC that I'm going to try and the Synergen looks mighty appealing.
Not sure which forum this info should be on so I threw the oil stuff in for good measure.

One out of "dozens" of new engines breaking a valve spring and having a valve eat the engine is a serious problem if the fleet wide ratio is one out of dozens.
Are you refering to the Hemi valve dropping problem that shuts down all the cylinders
Yea, only time will tell and I have a tendency to worry about this kind of stuff. But I believe that the valve thing was a production problem and not a design issue, not that that makes me feel any better. When and if I get tired of worrying about it I'll trade for a vette and get out of the truck thing all together.
You sound like me. Thanks for the update. If I run into problems, I'm going with the Tacoma or RSX next time.(manual) The Dodge trans is good. Much better then the previous Rams.
I want to wait about 2 years for the Tacoma bc it's a new vehicle.(Work the bugs out, if they have any.) I bouth my Ram in August of 2004. Currently have 4,800 miles on it. My car pool buddy is out on leave temporarily. I think my truck was assembled in July.
