b.
Alternative viscosity grades to improve starting ability where ambient below -20°C; 5W-30, 5W-40, 10W-30, 10W-40. These oils must have ASTM D4741 viscosity 3.70 cP min. API CF-4 oils may be used with reduced drain intervals

General Notes

1.
See Detroit Diesel Corporation Bulletin 7SE270 9706, 'Lubricating Oil, Fuel Oil and Filter Recommendations', for additional information on alternative lubricant requirements (DDC/MTU Series 2000/4000 only refer to Engine Service Fluid and Filter Requirements Publication 7SE273 9903). Synthetic oils may be used if API licensed and meet Detroit Diesel requirements. Must not contain VI improvers for 2-stroke engines
2.
Fuel sulphur content above 0.5% may require higher alkalinity oils and reduced drain intervals. Low zinc, high TBN Marine/Industrial lubricants are recommended for marine and railroad applications of Series 149 and other 2-stroke engines where sulphur content exceeds 0.5%
3.
Natural gas operation: See Bulletin 7SE272 for details.
