I also choose to do my own service on my
BX25. I have over 200 Hours now. It is a pain to take it to the dealer. Lose a day each way loading and unloading and the dealer would have for up two weeks (that's their backlog) as they only have one mechanic and no lube monkeys. I use it a lot more that. When I told the dealer what I planned they raised **** about using all Kubota products. I save a lot using NAPA products as my military discount gets me the garage price on all products. This comes out to 30-50% less than Kubota. They said that if I have engine, transmission, or hydraukic problems the warranty is automatically voided.
I use Delo 400 in the engine, and NAPA premium Super UDT in the tranny/hydraulics, and NAPA filters.
So, experience out there; what risk am I taking if any? Next Feburary it will be out of warranty anyway and I chose not to buy the extended warranty insurance.
