BX22 oil analysis

gsxr1100 · May 23, 2005

the oil looks to be going into the 30 weight (based on the saybolt #'s and not the normal vis table.)

Based on the lack of support from the dealer I would do this. Now this is me , run a small interval and then re-test. While you are trying to gain the hours, to do another test, I would call Kubota and let them know. But I would do another test to see if you have a fuel issue again.

But based on the numbers on your test I would say it might not happen on the next test or the fuel just started getting in the oil. If it was a long time with fuel in the oil, the wear would have been a lot higher, along with lower TBN etc etc.

To close, since doing oil testing the highest I have ever seen is 1.1% on my bike due to poor (cold) spark plugs.

Again this is me. I start my bike a lot. I have to since the heat is a killer on it.

**Ps, I start mine (BX22) more times then you I think since it only takes me 22 minutes to mow my grass...and that is in low gear!

should I go the 100 HR interval like the test said or test again before that? the small interval could be 20 HRS or so? or a little longer?

I was thinking around 50 +/- hours and see what you have.

Curious if this was the 50 hr break-in oil change. Might that have something to do with the high levels of fuel? I'm far from an expert, but maybe there was some blowby during initial break-in.

the test results reflest the last 50 HRS leading up to the 305 HRS the unit now has.
Im waiting on another Kubota dealer to get back with me to see what if anything they will do.

so the oil has 50 hours on it?

Garrabo · May 25, 2005

correct..

Ok, so the normal interval is 100 hours per Kubota. You only did only 50% of that. The unit should be way out of the break-in since you have over 300 hours on the unit.

Now I know Dargo stated all engines are different, which I agree 100%; But on the flip side if you drain the oil even sooner, you would below 50% of the normal interval (draining oil at less then half the interval required). That to me is flat out wrong.

So if you went sooner, you would be draining the oil at 25 to 40 hour mark while the book says 100 hours for oil drain. Give me a break. That is way to soon and where do you draw the line? Having a corrective action that is to drain the oil at 40% of what is normal, is not normal or correct in my book.

If you have fuel in the “50-hour used oil”, something is up. If you did not test the oil, you would double the interval you did. How many people even test their oil? Not much due to the whopping price of $20 to $25. J

I would re-test and see what is up. That, to me, seems to have something out-of-whack here. But then again, I am no expert.

Thanks, I cant find it on there web site.

I had high fuel in a fairly new Honda. I sent another sample in after the same duration oil change and it tested fine. You may be looking at a problem with the lab, not the tractor. The wear metals are all low, I'd expect to see higher metals if the oil was thinned out with fuel.

I use Oilguard, the tests are $9-$10/ea when purchased in quantities of 3 or 6. They also test for TBN, (the condition of the additive package). Based on your TBN of 10+ the oil is hardly used.

I'd retest in another 50 hours, if fuel is still present you have more ammo with your dealer. It could easily be a leaky injector.
