Designed for Reliability and Simplicity
70 Years of Reliability
B50 Life: 1.2 million miles
North America has some mean roads, from the scorching blacktop of the southeast to the frozen mountaintops of the Rockies. We design our engines to run through it all with minimal maintenance. The B50 life — an engineering term that means the point at which half of the engines are still running and half require rebuild — of a Detroit Diesel engine is 1.2 million miles. That’s the highest in the heavy duty industry, and it means you should expect the same workhorse effort out of the DD15™ that you got out of the bulletproof Series 60®.
Go Farther Between Servicing
To run farther between oil drains (50,000 miles for long-haul), we increased the size of the oil pan to 44 quarts, as well as the size of the oil filter. And changing the filter is fast: it’s an environmentally friendly cartridge style within arm’s reach.
“You do the oil change, you keep the air filter clean, and you don’t have any problems with the Detroit. They just keep going and going and going.”
Tried and True Turbo: With the addition of turbo compounding, we were able to return to the vastly simpler pre-EPA ’98 turbo. The fixed geometry-style turbo has fewer moving parts which translate directly into greater reliability.
The Only New Heavy Duty Engine: DD15
Detroit Diesel designed the DD15 from the block up with an eye to the future. Features like a more powerful and integrated Jake brake and the Exhaust Gas Recirculation (EGR) system have been integrated into the core design. We’ve even planned ahead for new EPA emissions laws in 2010 with design features that allow simple integration of Detroit Diesel's BlueTec After Treatment system.

Please Note: Service Intervals change with driving conditions and loads. For intervals that are more specific to your driving conditions, contact your Detroit Diesel authorized service outlet.
Severe Duty is up to 30,000 annual miles and a vehicle that averages less than 5 mpg. Short Haul is between 30,000 and 60,000 annual miles and a vehicle that averages between 5 and 6 mpg. Long Haul is over 60,000 annual miles and a vehicle that averages greater than 6 mpg.
