Devil Mountain Diesel - Frequently Asked Questions

I am new to the diesel world and just bought a used diesel truck. Where should I start?

We recommend making an appointment for a used vehicle inspection. If you don’t have the service records from the previous owner, we recommend doing a basic service so that you have a baseline to build upon for your own service records.

What does “BulletProof” mean?

The 6.0L is not a "BulletProof Diesel" engine unless four of the five main pattern failures are addressed with genuine BulletProof Diesel parts. Take a look at our BulletProof Diesel Products tab for more info.

How often should I bring my diesel in for service?

We recommend doing an oil change every 5,000 miles and fuel filters every 15,000 miles. Interested in more service information? Give us a call. (925) 954-8582

We recommend that you take the safe route by complying with such laws.
