Yes I had exactly same as your lower rpm oil warning light on problem.Jkk, thanks that is very good info! Did you have similar symptoms as me with oil light? I did research the spin on adapter but the oil filter assembly was set for certain psi relief? Or something along those lines. Been a while since I read up on it and I was worried about adjusting something that was set for a certain psi. Ill definitely go research it a bit more. The spin on filters will definitely be cheaper in the long run! Gosh just looked up in the manual. It says right here to replace it!
Thanks for your time. Much appreciated. Not sure she'd be running without everyone's help!
Just replaced the whole assembly because didn't want to play with valve in old one ( not much experience with orange tractors)
