I have a motor in my 803 that has a reset tag that said 2.5 hours. That is all I can decipher. The oil looks clean, but I am having low oil pressure when hot. Probably 25-30LB on the gauge. I am going to hook up a manual gauge to verify the electric. But thinking I need to change the oil to a 15/40 and start with a clean slate. I don't know history of the motor other than the tag. Would appreciate your thoughts. I have read the reset information on this site, but don't see anything that pertains to my question specifically.
