After reading all these warrenty issues on here, I was wondering if I could be denighed for using rotella. What oil is recommended on here?

if it means saving money, DC will void as much as they can, yes DC has done it to several people-----------nobody is safe any more

So does that mean that the Valvoline Premium Blue I just put in my 06 will void the warranty? I would think that as long as the oil is an API certified diesel oil that is appropriate for the application, that they couldn't void warranty. If I recall, the dealer I bought my 05 at said that they use Valvoline and the dealer I just bought the 06 at said that they use Mobil or some such oil. Regardless, if the dealers aren't using the same oils how could warranties be voided?

I'm not saying you are incorrect by the way, just trying to understand.

If the oil you use meets the Cummins specs, ie. API performance and SAE oil grade, you should be OK no matter what oil brand you use, and it can be a synthetic or petrolium type!

They will not void your warranty for using Shell Rotella. You must use CI-4 Plus and keep records of the change intervals. If you do extended drains you must do oil analysis.

The oil has to be API approved not just meet or exceed API requirements or you could run into a hassle with warranty issues.



That being said Rottela is API approved.

Just to expound on this, the Engine oil DOES NOT have to be "APPROVED" by anyone! It just has to meet or exceed the API specs for that application! When the oil Companies put the specs on the containers, they are saying the contents within meets the specs.



Oils are tested using ASTM or ISO standards, and the API sets the standards for Engine Service Classifications, currently Gasolene (SM) Diesel (CI+4).



The SAE sets the standards for Viscosities.

What does this mean? I right it down in the book, but what is CI-4

The API CI-4+ rating is a Diesel Engine oil rating. The "C" in the rating simply means Compression ignited Engines. (DIESEL) The "I" in the rating is the latest Service Applicaton, and the -4 means 4 cycle Engines. The + means it is applicable for the latest fuels out there which means the oil address "Soot".

I have moved in the last couple of months and I had always gotten my oil changed at the dealership cause I got a good deal. It would have been 70 or 80 dollars to get it done at the dealership here so I called my service manager at my old dealership about which oil to use and he told me to use rotella.

Wayne,

I'am not going to argue with you about meet or exceed or approved, which can lead to interpretation questions. The company you sell oil from does not certify with API so obviously you can say what you want.



I will say I think amsoil is a very good oil, it's just I would not and will not personally use it until my warranty is over. I don't want to give DC any leverage on warranty issues.

So Amsoil will is not a Certified oil?? I thought it was aproved for are trucks. Alittl insight would be good. I have been using Schaffers 5-40 series 9000 but was thinking to go to amsoil since my dealer isn't around any more.

That's were marketing comes from. Approved, meet, or exceed oil recommendation does not mean it's certified and tested by API. If the oil jug does not have the API donut with the oil catagories stamped on it the oil is not API certified no matter what the oil manufacturer claims it is. Not having the API donut could (could, not will) lead DC to void the engine warranty.

If you will look into this, you will find that NO oil is TESTED by the API! Oils are tested using the API standards, and then the Oil Company may have that oil "CERTIFIED" IF they pay the price that API requires for that particular oil.



As far as Amsoil having oils that are certified by the API, there are oils that they offer that are, in the Diesel oils as well as in the Gasolene engine oils. These oils that are "certified" are not as high quality however.



As far as the oils Amsoil offers that are not certified, I have never heard of an Engine manufacturer that has voided the engine due to the fact the oil is not certified, and Amsoil has been offering these oils for some 34 years! That should say something as far as API certification is concerned, wouldn't you think? Don't beleive me? Check into it yourself.
