I have not used it yet. I believe Cummins recommends Valvoline oil. I am REAL happy with the Shell Rotella T 5W-40 Synthetic in my Cummins. It stays clean looking much longer. I changed the filter and oil back in November and the oil is still clear on the dipstick when I check it. The Walmart price per gallon is a nice advantage too.

waltmart has a good price on rotella saw it for 12.88 a gal. I picked up a 5 gal pale of valvoline extreme for $70.00 just could not pass it up .did you notice anything different with synthetic 5w40 as far as milage, motor noise etc.

Prior to using the Rotella I have used nothing but John Deere 15W-40 Plus 50 Synthetic Blend. The only difference I have notice so far is that the Rotella 5W-40 Synthetic gives a slightly lower oil pressure at idle and gives off a signature Rotella sulphur like smell. Hence the nickname "Rosmella". It may hit full oil pressure on start ups slightly faster as well but not much faster. Fuel mileage may be a bit better but it is tough to tell in cold weather. Diesels fuel economy drops in cold weather. Pretty much it has been the same or slightly better.

the 2003 model came out with higher pressure in the fuel rails so more hp and quiter motor . mine is the 2003 but 250 hp, later that year they came out with the 325 hp and different pressure again in the rails . had 2001 diesel cummins and I do know what you mean , but the synthetic did make a big difference in cold starts as to valve train noise , the synthetic starts at 5w, and the dino oil I was useing was 15w 40 much heaver when cold , but it does seem quiter as 60 mph also

This is a Class 3 synthetic. It is derived by hydrocracking process on mineral oil. It is better than the normal class 2 mineral oils.
If you are going synthetic, a class 4 such as Amsoil will be a better product. The TBN package in the oil is better. The base oil is chemically engineered and has a better shear rating.
Overall, you will benefit by going to a synthetic. The properties are just plain better. If you are looking at extended oil changes as a reason, I would advise you use an oil analysis program. It is advisable anyway because it is like having a blood workup by your doctor. It will usually detect a problem that is starting to occur within your engine so you can get a jump on it before it ruins the engine. (such as a coolant leak or air that is bypassing the intake filter).
