Change (break-in period) oil now...or wait till spring?
 

Hi,

Changed the oil on my 129 after 5 hrs. following an engine overhaul, so now I'm at the point where it is suggested to change it again after an additional 5 hrs. of use; however, I'm likely to only use the tractor maybe 2-3 more times at most (where it gets used for about 1.5 hrs. each time) until winter.

I won't be using it over the winter at all, so I was wondering if I should change the oil now, which would remain in the engine all winter until spring, or mow with it a few more times as is, leave it over winter, then change it in spring. I have no problem changing it now and again in spring - but is it really necessary to do it now for the sake of another approximately 4.5 hrs. total use before it sits over the winter? All the tractor gets used for is mowing.

If not changing it again now, it would simply mean that the second (recommended 5-hr.) break-in period would extend to roughly 9-10 hours of maximum total use (if waiting till spring to change it - at which time I do all the lube, etc.). Prior to putting the new engine in, I never used to change oil after the mowing season ends, but the difference is that I also used the Cub to plow snow, but won't be doing that anymore.

IMO, If its full and clean you could put another 1.5 hours on it. Thats just me tho.

1.5 hours? That'd do one more mowing. So sounds like you'd advise changing it now, then again in spring.

Change it now... For the last 4.5 hours you will use it this year and fresh clean oil start of new season. It ain't all that hard to change the oil in a few minutes... Ain't it??

What B.O. said.

oil is cheap, ain't like it takes a 55 gallon drum.
Mow some to heat it up, and drain it hot and any contaminants will drain out more easily.
fill with fresh and sleep well all winter.:beerchug:

And then change it again in spring?

Your call, if it sweats a lot in storage on humid days, then yes change.

What you see on the outside of an engine, is also on the inside.:bigthink:
