My owners manual states 15W-40 SF/CD oil, I know those are obsolete specs. But it goes on to state after SF/CD "series 3 oil". I personally have never heard of such, have any of you guys (maybe gals) ever heard of this. Could be a misprint or whatever, it is an '07 tractor, I was kind of laughing when I first read the "CD" part, I contacted them about that, they said I need to run a CI-4+. Didn't think to ask about the series 3 part.
thanks
