I think I used 15-40 for the engine. It gets used 0-15 hours a year. The only reservoir I have had to add to is the hydraulics which was AM303. Just wondering if someone has a 70's tractor and if I should be concerned about the newer additives in most oils. Some additives are not good for...
Manual calls for AM303 for Torque tube/Power steering. AM303 for the Shuttle clutch. 80EP for the Transmission. SAE20-20 for the Final drive's. Was thinking SAE30 for engine? Not sure what Hydraulic oil to use? Tractor is is in northern NY but I only run it above 50 degrees. Thank you..
