Might be a dumb question but its my first diesel, but its time for an oil change for me, What type of oil should i use?? Is there a specific oil for diesel motors?? Im in miami FL so i dont have to worry about freezing temperatures or anything.

 

Yes there is. Rotella or Delo or a few others. I use the Delo 400 myself.

 

What about synthetic oil, should i stay coventional or go syn? ive got 59k miles on i assume conventional

 

Yes! It does have to be oil specified for Diesels... Delo and Rotella are good oils. If you're new here, try a search on oils and you will find a million opinions! I mention it to give you a good start to diesel education. We call it CTD U.

 

Redline, Royal Purple are a few. I've never run it before. But alot of guys here have with very good results.

 

I run Royal purple 15-40. It is ci-4 plus and meets cummins 20078 engine oil specifications. I have used it the life of the truck with no problems.

 

I have always used Mobile 1 in my other gas vehicles, I was think of doing the same for my truck. Any reason why i couldnt/shouldnt do it?

 

You could use mobil delvac.

 

YES!!! Oil for gas engines and diesel are not made the same. Specifically, Diesel oil is formulated to hold soot in suspension and the detergent and lubrication additives are different to combat the different acids produced by each.

YOu can go with Delvac or Premium Blue or Delo or Rotella or whatever... as long as it is Diesel oil Rated CJ-4 or CI-4.

If you like premium synthetics then there are a number of them. Royal Purple, redline, Amsoil, I use Shaeffers 9000. And more than I list here too...

Really-- I encourage you to do a thread search here and read the oil wars!! Best thing you can do to start out here.

 

I ment mobil 1 for diesel, but thanks. anyone happen to have a part # for the oil filter?

 

I use a NAPA wix filter # 7620

 

How much oil go into these trucks?

 

3 gallons /12-13 quarts. Make sure you fill the filter to the top FIRST before putting it on. You do not want to drystart the turbo, big no-no.

 

Thanks, i wouldnt have thought of that, ive never had to do that on my gas cars/truck before.

 

Oil is rated for API service, it'll be on the label, unless its Amsoil. An oil rated for a diesel will have an API classification like CF, CH, CG-4 or such as that. Oil rated for a gasoline engine will have its rating start with a S, like SF, SJ, SL. The "C" denoting compression ignition (diesel) and the "S" spark ignition. Not good to run oil rated for a gas engine in a diesel. Some oils lik eRotella T are rated for both.
Read your owners manual and see what it calls for and match it up. You won't go wrong with Shell Rotella, Delavac, Ursa, Fina, Exxon.
