(quoted from post at 10:47:44 01/05/17) Anyone know who refines TSC Heavy Diesel Oil 15w-40w? How does it compare with Rotella 15W-40w?
(quoted from post at 13:53:00 01/05/17)
but epa may have pulled zinc from their formula by now, I do not know,
(quoted from post at 15:15:03 01/05/17) I think people just generically call it 'zinc' because they don't know it's Zinc dialkyldithiophosphate (ZDDP)
(quoted from post at 22:03:36 01/05/17) Does posting on this sight mean that I don't own or operate diesel equipment?
(quoted from post at 00:52:59 01/06/17) It is acceptable and common to refer to this additive as Zinc, even major oil companies use it. It is not common to refer to the additive as Phosphorus though. ZDDP contains zinc and phosphorus.
The EPA did not mandate ZDDP levels in oil, but due to their mandate on the longevity of certain emissions devices is what required the reduction of the additive.
Diesel oil like 15w40 grade does have limits on additives including ZDDP. It wasn't much of an issue with the API CI-4 and older categories, but the most current CJ-4 & CK-4 have seen reduced levels, CJ-4 has been around for 10 years so this is not something new.

I am sure I could figure it out ,,, in a couple of days , LOL ,,, but you could probably answer it in a few minutes or less ,
In a nut shell any decent oil will be more than adequate for an N's needs . Some people like 10w30 and a lot of people like Rotella 15-40 .
I saw the chart on the 20-50 vs 30 and I had always thought the 20 would be thinner in cold weather
Around here 20 degrees is about as cold as you would start a tractor in cold weather up North maybe 0 ? ( not trying to start thread on the coldest start ever ) so how does the well liked Rotella flow on cold start ups compared to 10w30 in simple terms ?
