SkunkWerX, do you know if the cut-off pressure on the WIX is the same as the stock/factory one?
I struggled mapping a third party oil filter for my old generator. Didn't want to shell out big $$ for something with "Cummins" on it, when it's a Kubota engine! The WIX I got for it had a different cut-off pressure. I gambling a bit, but I don't run the generator much. To be honest, I'm not real sure exactly how the cut-off pressure would come in to play in a real life scenario.
I ran WIX and Pure One engine oil filters on my Kubota BX for almost 2,000 hours, with no issues.
The cut off pressure range was right in there.... maybe off by 1 psi at one end or the other. I really had good specs on the WIX end of things and considering how sketchy the Kioti information can be, I didn't really stress over it too much. I can see where a generator might potentially be a different animal, but I think you will be fine. I think the worst case scenario on any good quality oil filter is that it goes into bypass? Still flowing, doesn't blow off, engine is still lubing, just not filtering any more. The bypass is just a rubber valve, so i think that's why the manufacturers give us a range, because it probably varies a little between each of their filters.
Side Note: I have read about Kioti owners having smoke on start up. I was getting a little bit of smoke on the factory oil and filter. It is still warm weather, but I started hitting the warming element before cranking, and that took most of the start-up smoke away. New tractor, I figure the piston rings and valves are still seating and the smoke wasn't excessive so I just watched it. NOW, after doing the oil change, no smoke, at all, on start up! Also, it barely cranks on start up, just hit the key and it pretty much fires on the first revolution. I have less of that gravelly diesel sound and less engine vibration at idle. Anyone getting close to the 50 hours, don't hesitate, get that factory engine oil out of there, use a premium grade 15w40 diesel engine oil and hopefully you will see the results I just experienced.
It made a difference.
