A Diesel Engine That Demands Proper Care

The 6.7-liter Cummins is a capable and long-lived engine when it is properly maintained, but it has specific service requirements that differ from gasoline engines and from other diesel platforms. Fuel system maintenance is critical on the Cummins because the high-pressure common rail injection system is sensitive to fuel quality and contaminated fuel filters. The exhaust after-treatment system, including the diesel particulate filter and the DEF system, requires its own attention to avoid the kind of failures that can take a truck off the road unexpectedly. We handle oil changes with the correct diesel-rated oil, fuel filter service, DPF maintenance, turbo system inspections, cooling system repairs, and full diagnostics for Cummins-powered vehicles.

Good Questions. Here Are the Answers.

These are the things Cumming drivers ask us most. Do not see yours? Give us a call and we will help.

How often does a Cummins diesel need an oil change?

The 6.7-liter Cummins requires a diesel-rated oil meeting Cummins' CES 20081 specification, and the oil change interval depends on how the truck is used. Under normal conditions, most Cummins owners follow a 15,000-mile interval, but trucks used for heavy towing, hauling, or operating in dusty conditions should be serviced more frequently. Cummins also recommends shorter intervals during the break-in period on a new or rebuilt engine. Using the correct oil specification and staying on the appropriate interval is one of the most important things a Cummins owner can do to protect the engine long term.

What are the most common repair issues with the 6.7-liter Cummins?

The 6.7 Cummins is a strong engine but a few things come up with regularity. The EGR system, including the EGR cooler and EGR valve, can develop failures that affect performance and fuel economy and in some cases cause coolant loss. The diesel particulate filter requires attention on trucks that do a lot of low-speed or short-trip driving since those conditions prevent the natural regeneration cycle from completing properly. Lift pump failures are also something that shows up on higher-mileage Cummins trucks and can cause hard starting and fuel system issues if not addressed.

Can you work on a Cummins that has been deleted or modified?

We work on stock Cummins trucks across the full lineup. For trucks with emissions delete modifications, call us first to discuss the specifics. Some modifications affect what we are able to diagnose and repair, and we want to be upfront about what we can help with rather than making promises we cannot keep after the truck is already in our shop.
