EPA07/EPA10/GHG14/GHG17 Preventive Maintenance Tables - 93K222(CK-4) and 93K223(FA-4)

EPA10/GHG14/GHG17 DD Series Preventive Maintenance Tables - Ops

Note: Actual fuel filter life will vary based on fuel quality.
Note: Diesel Oxidation Catalyst (DOC) and the Selective Catalytic Reduction (SCR Catalyst) do not require maintenance. (Does not apply to EPA07)

Note: If your vehicle has the Maintenance System enabled, please follow the recommendations communicated via the ICU Panel or Detroit Connect for Engine Oil and Oil Filter.

Note: Refer to your vehicles Driver's Manual for a detailed explanation of the Maintenance System.

93K222(CK-4) and 93K223(FA-4) Oil Service Interval Definitions (applies to the following tables):

Efficient Long Haul (over-the-road transport) service applies to vehicles that annually travel more than 60,000 mi (96,000 kilometers) and average greater than 7 mi per gallon with minimal city stop-and-go operation and minimum idle.

Long Haul (over-the-road transport) service applies to vehicles that annually travel more than 60,000 mi (96,000 kilometers) and average between 6.0 and 6.9 mi per gallon with minimal city stop-and-go operation.

Short Haul service applies to vehicles that annually travel up to 30,000-60,000 mi (48,000-96,000 kilometers) and average between 5.1 and 5.9 mi per gallon

Severe service applies to vehicles that annually travel up to 30,000 mi (48,000 kilometers) or average less than 5 mi per gallon or that operate under severe conditions. Severe service also applies to RV applications. Only one of these conditions needs to be met to categorize an application as Severe Service.

Diesel Particulate Filter

EPA10 & GHG14

A Check Engine Indicator or mileage/time intervals indicate when ash cleaning is required. Use DETROIT Diesel Corporation's authorized DPF cleaning procedure. Failure to follow this procedure could result in engine and/or aftertreatment damage, causing degraded vehicle performance including excess fuel consumption and decreased engine life.

Normal DPF ash clean intervals are 300,000 mi (480,000 km) 9,000 hrs to 400,000 mi (640,000 km) 10,250 hrs.

Detroit highly recommends exchanging the DPF with a Detroit™ genuine DPF to ensure maximum life.

DEF Pump Air Bladder

2010 Engines only: Refill bladder with air every 24 months.

- 1 Vehicles used a majority of time on rough, dirty, rocky roads should have their belts replaced sooner than recommended. Debris can get caught in the belt system and wear out belts sooner than vehicles used on paved highway roads.

- †Whichever comes first. Note: Reaching the Davco change line supersedes these intervals.

- *Engine fuel filters should be changed at recommended service intervals, or when the "Fuel Filter Service Lamp" activates on the dashboard. For maximum life of fuel system components, it is not recommended to exceed 100k mi on engine fuel filters under any condition.

-** Check per section "Poly-V-Belt Inspection".

- ***Fuel Economy represents overall fuel economy (including idle time)

- ‡Currently, only Detroit™ Fuel Filter/Water Separator & Davco 385/482/485/487 are the only frame-mounted filtration systems compatible for Detroit™ Engines.

- §Maintenance System can be enabled for this component.
