Short story: Yanmar TF500 is Castrol UTF with red color addative per Yanmar.
Long story: bought a new EX3200, but it has the wrong hose fittings on the CL300 FEL to Yanmar quick disconnects and leaks fluid. Dealer did not have Yanmar TF500 or Cub Cadet 737-3025 trany/hydralic oil. Called Yanmar Customer Service and explained the situation. Of course, they said I had to use TF500 or the Cub Cadet oil. I told them that they did not have it and explained the there has to be another fluid to use. He repeated that I needed to use eith of those oils. I explained that that was like saying you could only use GM oil in a GM vehicle or Ford oil in a Ford to maintain the vehicle or the warranty. He was silent for a couple of seconds and the n said what's your number, I'll call you right back. About 10 minutes latter he called back and said it was Castrol UTF.
