Diesel Oil Change Service
Diesel Engine Repair — Cheyenne, WY
A diesel oil change isn't the same as a quick-lube visit. These engines hold two to three times the oil of a gas engine, demand the correct specification for their emissions equipment, and benefit from having a diesel mechanic's eyes underneath the truck while it's draining — catching seeps, worn hoses and loose components before they become breakdowns.
TDC uses the correct-spec oil and quality filters for your engine, and because Trevor works on these trucks every day, an oil change here doubles as a health check from someone who knows what a 5.9 Cummins or a 6.7 Powerstroke is supposed to look like underneath.
What's Included
- Correct-spec oil for your diesel and its emissions system
- Quality oil filters — no bargain-bin parts
- Underside inspection while it drains
- Cummins, Powerstroke and Duramax pickups
- Straightforward pricing, no upsell games
Diesel Diagnosis Done Right
- Verify and inspect
Every diesel complaint starts with reproducing the symptom and a physical inspection — leaks, soot trails, boots, clamps and wiring.
- Test the systems
Compression tests, fuel system diagnostics and turbo checks isolate whether the problem is mechanical, fuel, or air.
- Confirm before replacing
Injectors, pumps and turbos are expensive. Nothing gets replaced until testing confirms it failed.
- Fix it for the long haul
Where a known weak point exists — like CP4 injection pumps or grid heater bolts — Trevor will tell you about the proven prevention options.
