Diesel Maintenance FAQs


What maintenance is required for a diesel engine?

Diesel engines crank up the heat compared to their gasoline counterparts. This hotter environment means they're thirsty for fresh oil more often, demanding regular changes and quality checks. To keep them humming through winter, a splash of liquid additive can be their best friend, both during those chilly months and in the spring thaw.

How often should diesel injectors be serviced?

While 95,000 miles is the general lifespan for diesel fuel injectors, don't blindly stick to that number! Your specific car's make, model, and driving habits can significantly impact when they need replacing. Keep an eye out for warning signs like rough idling or decreased fuel efficiency, and consider scheduling a checkup even before hitting the 95,000-mile mark.

How long does a diesel engine last?

A well-maintained diesel engine is a mileage marathon runner. Expect 1 million to 1.5 million miles before major repairs, and some makes and models even boast 30 years of service on the road. That's more than twice the average lifespan of a gasoline engine, thanks to their robust construction and efficient combustion process.

Here's a rewritten version: B&M Auto Repair definitely delivers! After AutoZone scanned the codes for my misfiring truck, I was stuck waiting 2 weeks for a dealership appointment. But B&M got me in and out within 24 hours, handling my warranty claims directly. Their professional service and expertise got my truck running smoothly again and it's been running amazing ever since
