Designed for Reliability and Simplicity
70 Years of Reliability
"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."
B50 Life: 1.2 million miles
From the scorching blacktop of the Southeast to the frozen mountaintops of the Rockies, North America has some mean roads. Detroit Diesel engines are designed 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 each Detroit Diesel engine.
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.
