So are most people using CJ oil now??
I have a John Deere right next to me so I can get CI oil, but the CJ is cheaper at Auto parts stores. My Question is since CJ has been out for awhile now is anyone experiencing any problems with using it? Is CI still that much better to run?
Thanks

Considering that ULSD is pretty much all there is at this point for on road use, CJ oil should be just fine. It has had a pretty good run since the beginning of 2007.

Nope, I'll buy the more expensive JD 50 oil or the Amsoil HD 15W40 that are both rated at CI-4+ before I'll even glance at the CJ-4+ stuff.

What's the specs on the JD oil? Meet cummin's specs? If it's in gallon jugs it would be nicer than dealing with 5 gallon buckets I currently use for the CI4.

Here's the deal. The differance between the two oils is that the new CJ has about 25% less ZDDP than the older oils. Zinc is used to prevent engine wear.
The reason for the reduction is that all engines will burn a certain amount of oil, even when properly broken in. As we all know, the older the engine gets, the more it burns. The burned zinc clogs the cat, and raises emissions. Gas engine automotive oils dropped their zinc levels many years ago. Diesels didn't have cats until recently, so the change wasn't required until recently. Engines that really need that higher level of zinc are that that have flat tappet lifters - no rollers. As I read through my service manual, it appears that my '07 Cummins engine has flat tappets. Gas engines have been using roller lifters for many years. So, as I see it, I have two choices. I can use an oil with higher ZDDP levels and protect the cam and lifters, but maybe sacrifice the cat. OR, I can use a low zinc oil, and maybe lose the cat. Both are covered under warrenty, so cost is not the issue. If the cat goes, it will be slow. And the fix is pretty simple. If the cam/lifters go, it's a complicated fix that could take weeks. I can't afford that kind of down time. And I can't afford to be stranded in the middle of WY on a holiday week end. So I'll add some ZDDP to the standard CJ oil.

CJ spec exceeds CI ratings, why is everyone freaking out? No need to run out and buy additives...
Do your research, not just on this board of "experts".. |

So in what ways does it exceed the CI ratings? Everything I've read has been about the lower zinc levels which affords less protection. But then again, maybe I haven't been reading the right things.

you're assuming the zddp is the only thing than can give your oil a HTHS rating ..
http://www.apicj-4.org/performance_specs.html in a couple years, manufacturers will likely stop making CI oil anyway... what are all the oil guru's going to do then? in essence the CJ-4 oil spec is the current industry standard... only a matter of time.. |
