Tractors
The recommended oil for use in Massey Ferguson 135 tractors is a multi-grade 10W-30 or 15W-40 engine oil. The oil should be full-synthetic and designed for 4-cycle diesel engines. It should also meet specification API CI-4/SL and provide anti-wear protection and detergents to help keep the engine free of sludge and other deposits. The oil should also meet JDM J27 and Massey Ferguson specification MF-M1135. Note that using non-approved oils can damage the engine and void any warranty coverage.
