 East of Broken Bow | This is what I was going to say. If you use a semi-synthetic or synthetic blend oil, there is no regulation on how much is synthetic and how much is regular oil. Could be an eyedropper full per gallon, or it could be half/half, you just don't know.
Personally, if I wasn't going full synthetic, I would go with a known good oil, have never had complaints about CaseIH #1 oil, and I would also consider Farmland oil from Coop as I think they even have an engine rebuild guarantee if you use their oil exclusively. I think Schaffer's is great oil, probably one of the best, but I'm just not sure I'd spend that much extra over the Case stuff for it. If anything, I'd run the Case and maybe change oil a little more often. | |
