Looking for an oil with a bit more zinc in it, what is everyone running?
This ^^^I run it in my Cummins, but awhile back (a few years ago) I read that it doesn't have as much zinc now as it used to.
Is trhat the 20W50 you're running?Valvoline VR1 is what is most easily accessible around here.
Yes the 20 50 . Comes in a 5 quart container from the parts store.Is trhat the 20W50 you're running?
I have used Rotella. It still is one of only 2-3 with the proper rating on it. I forget the letter, S maybe?Looking for an oil with a bit more zinc in it, what is everyone running?
