Reddman, I'll say this not intending to hurt feelings or show disrespect of any kind or way. This is my opinion and personal view on this subject.
Looking at the equipment you have listed and assuming you purchased it new I'm guessing you spent upper teens, close to 20K for everything. I look at this in 2 different ways.
1. You don't plan to keep the tractor long
2. You plan to keep it till it dies
If you are thinking number 1 then I say run the cheapest of everything because it don't matter, it won't be your problem after it's sold.
If number 2 is more along the way you feel why would you want to shorten the life span of your tractor by saving $20 on a oil change. It's not like you need to change oil every month or two. I'm not saying that you have to use Kubota oil and fluid, I don't. But I didn't look for cheaper, I looked for higher quality instead. I plan on my tractors to outlast me and still be in good shape for my kids when they take over. I'll gladly pay extra for quality lubricants now instead of spending thousands in repairs later.
Like I said this is only my opinion. I didn't fire a warning shot or set any land mines. I have no intention of starting a oil war, please...
