As the title says, I'd like some opinions of different oils and filters. I'm currently running Rotella because it was in the truck when I bought it. I'd really like to hear your opinions and stories of your experiences. Thanks in advance!

most everyone is going to say use Amsoil. for engine trans
I'm using Valvoline 15w40 for engine and Cummins engine oil filter. only because its free to me
if i had to pay i'd probly use the same.
I used to use Fram filter but not anymore the Crimp leaked on a oil filter i had on my truck once and never used it again. I guess that could happen to any filter maker. But since cummins filter is free i use it

I also use Valvoline synthetic ATF+4 trans oil. Again Free to me so.

i run cummins approved valvoline. and a guy i know that works for UTA the transit system in Utah. he said thats the only thing they run in the 5.9 and 6.7 cummins busses that drive around all day everyday ..

also if your pocketbook can handle it royal purple is great but for $130 a change i think i'll be fine with the valvoline

I run the AMSOIL of course. Kinda depends on what you want out of your oil. Are you good with changing it at OEM intervals or are you interested in stretching it out a bit? I currently have 24000 miles on my oil. Just got an OA back yesterday. All is still ok.
Synthetics have their advantages but they come a little price. That price can be negated if used how they can be.

Thanks folks! Heath, I'll be giving you a call in the near future. I have some things I would like to discuss with you.

I now run Valvoline 15w/40 Cummins oil and add two bottles of ZDDP with every oil change. I run WIX oil filters.

I used to use Rotella until they changed their formula reducing the Zinc. The '07 and up engines are fine running the newer oils but the 06 and earlier engines need the old formulas with the higher zinc levels. The newer oils comply with new government standards to help with emissions.

I've long been a fan of Valvoline oils, and was intrigued by their new formula that is specific to Cummins engines. To ensure that I'm getting sufficent zinc to protect camshaft and lifters I add the ZDDP.

If you read closely on the Valvoline bottle it is specifically for the ISM and ISX Cummins, no mention of the ISB engine that is in our trucks.

The ISM and ISX engines are heavier duty engines. Is there a concern with using this oil in our lighter duty ISB engines?

Does anyone have any information on the OEM Mopar oil that came from the factory, or that perhaps the dealers use?

Since were talking oil, just curious how long most of you guys go between changes? I do not do much pulling but living in the mountains causes a little more work. Also, does it matter having the aftermarket mods done

Thanks

I run Amsoil in my truck with an Amsoil filter. For stock trucks the normal service mileage recommendation is 25,000 or 1 year, but if you have mods or tow heavy or any other reason to consider it severe duty then they recommend 15,000 miles. I usually change mine around the 15,000 mile mark. I don't run my truck hard, I only tow about 12,000 lbs 2,500 miles or less a year, but I do have a programmer.

Doug

Thanks Doug, souds like Amsoil and use the severe duty guidelines is the way to go. I plan on changing the oil when I get home from Iraq in early Feb even though the oil only has about 5000 miles on it because it will have been in there for over a year.

Chet

Well at the moment im using delo and running a fleetguead filter. I will be puting a bypass on in the future when it starts to warm up agian. Been thinking of the amsoil. I have that in my 96 dodge and its good stuff. Shell aint bad stuff neither is the mobil delvac. Realy as long as it conforms to the API standards to your engine you should be fine. Seeing as all the brands stated above do I say you should be fine.

Well if you are fueling hard like from bigger injectores and working it hard ex sled pulling, raceing , heavy towing, extended ide time then yeah its a good idea to change it a little sooner. Least thats what I would do.
