Recommended Lubricants and Fluids - SAE Viscosity Number
MA-15spec tableSAE viscosity recommendations differ for gasoline vs diesel engine oil and for gear oil. Turbo-engine note: 5W-20 not recommended, 5W-30 only under extreme cold. Gear oil differs for North Europe (80W-90) vs except North Europe (90) for differential gear.
SAE Viscosity Number
Gasoline engine oil — For cold and warm areas: 10W-30 is preferable for ambient temperatures above -20°C (-4°F). For hot areas: 20W-40 and 20W-50 are suitable. On turbo engines, 5W-20 is not recommended. 5W-30 should be used only under extremely cold conditions.
Diesel engine oil — For cold and warm areas: 10W-30 is preferable for ambient temperatures above -20°C (-4°F). For hot areas: 20W-40 and 20W-50 are suitable.
Gear oil — 80W-90 is preferable for differential gear (for North Europe), transaxle and transfer for ambient temperatures below 40°C (104°F). 90 is preferable for differential gear (except for North Europe).
