i recently noticed that one of my 200hp ox66 motors was burning more oil than the other one so i talked to a few people and they told me to adjust my oil rods so i looked in the shop manuel and did it the way the book told me to my motors are burning alot less oil the last trip i burned 100 gallons of fuel and only burned 1.5 gallons of oil (192oz)wich at 50:1 that really is not enough oil does the oil valve change the oil ratio at different rpms if i was pre mixing the gas i would need 260oz for 100 gallons of gas they are 2000 model efi 0x66 yamahas
so does that means its not always based on 50:1 and my motors are getting the right amount of oil all i did was set the oil valve lever back to the stop while the shifter was in the neutral position just like the book said
