Oil Drain Intervals for DD Platform Medium Duty On-Highway Engines

The oil drain intervals for GHG17 DD5, DD8 Medium Duty On-Highway engines listed in the tables below are based on engines operating with Ultra-Low Sulfur Diesel (ULSD) fuel (below 15 ppm) meeting the properties listed in “Diesel Fuel Properties” table with a Detroit Fluids Specification DFS 93K223 or DFS 93K222 approved oil. API FA-4 or CK-4 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.

Maximum Oil Drain and Filter Change for DD5 using Detroit Fluids Specification DFS 93K223 or DFS 93K222 Approved Oils with ULSD Fuel
Engine Series Long Haul*

> 12.0 mpg

 Short Haul†

10.1 to 11.9 mpg

 Severe‡

< 10.0 mpg
DD5 50,000 miles (80,000 km) 45,000 miles (72,000 km) or 1500 Hours or 18 Months 35,000 miles (56,000 km) or 1000 Hours or 12 Months
*Long Haul service (over-the-road transport) applies to vehicles that annually travel more than 60,000 miles (96,000 km) and average greater than 12.0 miles per gallon 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.
†Short Haul service applies to vehicles that annually travel up to 60,000 miles (96,000 km) and average between 10.1 and 11.9 miles per gallon 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 average below 10.0 miles per gallon or that operate under severe conditions. Examples of Severe Service are: idle time over 40%, 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; or farm operation. Only one of these conditions needs be met to categorize an application as Severe Service.
