JD4010 oil weight?

Justin SE IOWA · Oct 5, 2012

Im gonna change the oil on my new to me 4010. What is a good oil weight to use in it? I use the tractor year around and only change the oil once a year. Advice appreciated.

By the way its a gas tractor.

Winter is coming up, would use 10W-30 if it is setting out, or 15W-40 year round if not.

We use 15W-40 in 4020 year round and it sits out, just put a heater on it night before when using it.

We use 15X40 in everything (even the lawnmower), except newer stuff that takes 5W X 30. (can't bring myself to use 5 X 20) Also get the older formulation of 15 X 40, not the one for the 07 or newer diesels.

Used to run straight 30W in 4020D, just like owners manual said. But in the last 10 years or so, oil companies have fixed all the problems with multi-viscosity oils, so we run 15W-40 in all our diesel engines.
For a gasser, I'd go with the 10W-40
