The number$450 flat, one number, nothing added at the end
TurnaroundSame visit, on-site, the truck never moved
How it went
- 1Full synthetic oil service. The correct heavy-duty spec, all twelve quarts of it.
- 2Both fuel filters replaced. The pair protects the high-pressure injection system; skipping one is how injectors die.
- 3CCV filter replaced. The interval item most quick-lubes never mention.
- 4Forced DPF regen + codes. Soot burned down under scan-tool control, codes read and cleared, truck road-ready the same visit.
Why a business customer counts double. A used-car lot owner knows exactly what this service is worth and what a dealer would charge for it, there’s no talking someone like that into a number. Repeat commercial work is the hardest reference to fake and the easiest to lose, which is exactly why it’s worth listing.
Why this one’s worth reading: modern diesel service is where “just an oil change” stops being simple. A 6.7L Cummins takes twelve quarts of the right oil, runs two fuel filters people forget, has a crankcase-ventilation filter on a service interval, and the emissions system needs real diagnostic tooling, not a parts-store code reader. A forced DPF regen is a scan-tool procedure with the engine managed the whole time. All of it happened in the parking spot where the truck sat.
The honest note: a regen isn’t a magic wand. A filter that’s been neglected long enough needs professional cleaning, and if that’s what your truck needs, I’ll tell you instead of selling you a regen that won’t hold. Straight answers are the whole model. And to be explicit about the thing people ask diesel guys for: DPF and EGR deletes are illegal, and I turn them down, the answer doesn’t change based on what it’s worth. That and the rest of the list is on the trust page. The work I do take is covered by a written 90-day workmanship warranty.
