Engine oil change Interval Jd 3520

Deere Dude · Mar 12, 2016

If I put on maybe 100 hours a year and it is recommended to change every couple hundred hours or yearly, am I better off changing the oil in the late fall or the spring before the mowing starts? There is not much use after November.

I would change it in the spring so you can start with fresh oil before the heavy use season but I don't think it matters much either way.

I do mine in the fall so I'll have nice clean oil in it's best state for all the cold weather starts it will get.

I can agree with that logic. My reasoning for the other way is acids build up and oil deteriorates over time so if you change in the fall your oil will be getting older and worn by the time your heavy uses season rolls around. In all reality it probably doesn't matter much either way. I have a ton of things with engines and sometimes something that doesn't see a lot of hours slips by and goes over a year without an oil change and I haven't had any problems yet.
