BX24 oil too clean

[PeterK]

I know this sounds a bit weird but I've always changed my own fluids, my BX now has ~600 hours. Usually the clean oil will turn black after a couple of hours use. But this time, it is staying much cleaner. I've put about 15+ hours on this oil change so far, mostly heavy snow blowing and winter work. But I can still see through the oil. Pull the dipstick, it's getting a little dirty but it is still clear, no black as I usually see. I expect after 15 hours it would be jet black.

Anyway, it's had me worried something is wrong. Could it be the filter is messed up some how. Always genuine Kubota parts and oil.

Any ideas?

What oil?

Sounds like you may have gotten a non-detergent oil instead of a diesel grade of oil.

Your engine is just clean. You probably change your oil more than necessary. How many oil changes have you done on this engine?

This seems like a good possibility, except you mention that you always use genuine Kubota parts and oil. You are sure of the type of oil you used this time?

Oil filter can't take enough color out to notice, in fact the dirtier it gets the better it filters (up until bypass mode).

Maybe a change in the type of fuel?

All good suggestions. Funny we're trying to get my oil dirty with suggestions.

I change my fluids on the Kubota schedule + or - . I buy my filter and oil at my local Kubota dealer. 15W40 Kubota oil and filters. This was also my first antifreeze change and I used premixed in the cooling system.

Same fuel and I also have always used Diesel Power Service additive. Pour about 2 oz into my empty 5gal jugs and fill with diesel. Perhaps I double dosed a can and the additive is keeping it from getting dirty? I have a routine so it's doubtful but always possible. It runs strong. No changes at all other than the too clean oil.

So here's a Q. Has anyone else noticed this or is everyone's oil dirty almost as soon as you start it like mine used to be?

Peter, I purchased a 1976 Bolens G-152 back in 2006, and every oil change it turned black the first hour! In 2010 I purchased a new TYM 233 and change the oil every fall (usually less than 50 hours/year). It is still clear when changed. To me, the frequency of changes makes all the difference in what the used oil looks like.

Good question . We farmed with LP minnies and that oil looked as good as gold at 100 hours as the day youput it in . The diesel engines were black as soon as youstarted it . Can someone explain this .

It depends on several things; how dirty the former oil was, how thoroughly it drained [angle - hot or cold], state of ring sealing [break in issues at your hrs particularly], etc. ... The oil in my Mahindra does not become opaque for at least an hour. I dont know much after that cuz I dont usually check it for another 100hrs or so. Its black then.
