For anyone who does not run synthetic engine oil. CAT is still making there making their oil to CI+4 standards. I work for a cat dealer and if this is good enough for a new ACERT its good enough for my cummins.

 

It's Delvac with CAT's own proprietary additives to meet their often more stringent requiremements...it's good stuff.

 

Where can you get it? I started using the John Deere CI-4 stuf as well!

 

Any CAT dealer, or some truck dealers as well...

 

What's wrong with the Rotella 5w-40 syn?? it's not too expensive and you can get it at Wal-mart (virtually anywhere)

 

nothing wrong with it i was just letting everyone know that if your still running standard engine oil, the cat oil is pretty cheap and it is good stuff. Like i said if its good enough for a new ACERT its good enough for me.

 

Acert? Not sure what this is.......

 

I think he just means that your 5w-40 Rotella is the new CJ, not the CI.

 

O....I did not know that...i should probably switch back huh? I'm guessing the regular Rotella would be fine?

 

Regular Rotella is still CJ as well. Hard too find the old (good) stuff. Try going to a bulk dealer and looken, or just buy Amsoil, John Deere, Cat, ect... Just check to make sure it says CI4 on it and not CJ. There are a lot of post on here about it. Kind of a heated debat.

 

2010 looms on the horizon.....
