Oil Drain Intervals for EPA07 Medium Duty On-Highway Engines
The oil drain intervals for EPA07 MBE 900 On-Highway engines listed in Table "Maximum Oil Drain and Filter Change Intervals for MBE 900 using Detroit Fluids Specification DFS 93K222 and DFS 93K218 Approved Oils with ULSD Fuel" are based on engines operating with ULSD fuel (below 15 ppm) meeting the properties listed in Table “Diesel Fuel Properties” with a Detroit Fluids Specification DFS 93K222 and DFS 93K218 approved oil. API CK-4 and CJ-4 certified oil that is not Detroit Fluids Specification approved may be used at reduced drain intervals. These intervals should be considered as maximum and should not be exceeded.

|---|---|---|---|
| Service Application | Long Haul * | Short Haul † | Severe ‡ |
| Engine Series | |||
| MBE 900 | 20,000 miles (32,000 km) | 15,000 miles (24,000 km), 500 h or 6 mon§ | 6,000 miles (9,600 km), 250 h or 3 mon§ |
| * Long Haul service (over-the-road transport) applies to vehicles that annually travel more than 60,000 miles (96,000 km) with minimal city stop-and-go operation. Examples of Long Haul service are: regional delivery that is mostly freeway mileage, interstate transport, and any road operation with high annual mileage. | |||
| † ShortHaul service applies to vehicles that annually travel up to 60,000 miles (96,000 km) or with a load factor over 45% and operate under normal conditions. Examples of Short Haul service are: operation primarily in cities and densely populated areas, local transport with infrequent freeway travel, or a high percentage of stop-and-go travel. | |||
| ‡ Severe service applies to vehicles that annually travel up to 30,000 miles (48,000 km) or that operate under severe conditions. Examples of Severe Service are: idle time over 35%, load factor over 55%, operation on extremely poor roads or under heavy dust accumulation; constant exposure to extreme hot, cold, salt-air, or other extreme climates; frequent short-distance travel; construction-site operation; city operation (fire truck or garbage truck), or farm operation. Only one of these conditions needs be met to categorize an application as Severe Service. | |||
| § Whichever comes first. | |||
| NOTE: Load factor and idle time values must be based on DDEC reports that accurately represent the current service application. | |||
