Wow Lou, Are you trying start the 1,000th debate on this forum concerning oil quality? We are really talking well over a $100 cost difference between Costco Premium tractor fluid and one of the "brand" names for changing the hydraulic oil on a 4720. I guess I am not as rich as some people, because to me that isn't small pocket change. I have never heard a fact based argument that the store brand oils that meet the correct specs are any better or worse for your tractor than the brand names. Now if you put 303 fluid in your 4720, you will have screwed up. But we are not talking about that. We are talking about a fluid that meets Branson's specs. You hear arguments about not all oils are the same, and the additives and quality of additives between various fluids, but no one can seem to quantify what they are talking about in any way that is more sophisticated than biased marketing hype.
Personally I am not in the slightest bit convinced that Chevron brand at $110 per 5 gallons is a single iota better than Costco Premium tractor fluid at $47/5 gallons. I would love to see an independent fact based study showing otherwise. I wouldn't try to convince anyone not to put expensive fluid in their tractor if they want to. It will work just fine. But unless someone can produce something more substantial that anecdotal based arguments, I remain unimpressed by the old "is it really worth the x dollars" line.
Screen cleaning ring a bell with anyone? I see nothing in the manual about a transmission screen. Just a radiator screen.
