Iíve searched for a discussion on this, but no luck, so here goes:
I am getting ready to do my annual oil change. The dealer sold me some Plus-50 that is 0-W-40, but when I was getting set up today I found I still had an unopened jug from last year that is 10-W-30.
I plan to to use the tractor occasionally at sub-zero temperatures this winter. Next spring and summer will see a lot of use for a new project we are planning.
Wondering which oil I should put in now. And which to use next summer?
(Itís been a couple of months since I bought the newer oil, and likely cannot return either jug.)
