If your trucks are making you money, they're not in the shop. I provide mobile preventative maintenance for heavy duty diesel trucks and commercial fleets across the Treasure Valley. I come to your yard on a schedule that fits your dispatch, service your equipment, and get you a clear record of what was done and what to watch, So you catch the $400 problem before it becomes the $4,000 problem on the side of I-84.
Mobile PM at Your Yard
Most fleet PM work doesn't require a shop bay. It requires a mechanic, the right fluids and filters, and a couple of hours per truck. I bring the service to you. That means:
- Trucks don't lose a dispatch day driving to a shop
- I can service multiple units in one visit
- You don't pay for shop labor markup on routine work
- Your records stay consistent — same hands, same standards, every interval
For fleets with their own facilities, I'll work around your dispatch schedule. For smaller operators, I can come to a yard, a home base, or wherever your truck sleeps.
PM Services I Provide
A typical PM service covers:
- Engine oil and filter change (using oils that meet your engine manufacturer's spec — CK-4, FA-4, or older grades as required)
- Fuel filter and water separator service
- Air filter inspection and replacement as needed
- Coolant level, condition, and SCA testing
- All grease points and chassis lubrication
- Brake inspection — pads, drums, slack adjusters, air system check
- Suspension and steering inspection
- Tire pressure, tread depth, and wear pattern check
- Lighting and electrical inspection
- Belts and hoses
- DPF and after-treatment system check
- Fluid leak inspection
- Battery test and terminal service
- Visual driveline and U-joint inspection
You get a written report of what was serviced and any items that need attention before the next interval.
PM Intervals That Fit Heavy Duty Work
Heavy duty diesel PM intervals depend on the engine, the application, and the oil. There's no single right answer, but here's the general framework I work from:
- A-service (every 10,000–15,000 miles or as the OEM specifies): oil and filter, inspection, lube, top off fluids
- B-service (every 25,000–35,000 miles): A-service plus fuel filters, air filter, more thorough inspection
- C-service (annually or 50,000+ miles): full PM with coolant service, transmission and differential fluids, and a comprehensive inspection — pairs well with the DOT annual inspection
If your trucks run heavy idle, dusty conditions, short routes, or stop-and-go work, intervals shorten. If they're highway miles with light load, intervals can stretch. I'll help you build a schedule that fits how your trucks actually work, not a generic chart.
Pair Your PM With Your DOT Inspection
The most efficient way to schedule fleet service is to combine your annual PM (C-service) with your federal DOT inspection. Same visit, same downtime, two compliance items checked off. If you run loads into California, we can also schedule your 90-day BIT inspections to land on PM-friendly dates. Learn more about DOT and BIT inspections.

Frequently Asked Questions about Preventative Maintenance
Two reasons: avoiding breakdowns and protecting resale. Unplanned downtime on a Class 8 truck regularly runs $1,000+ per day between lost revenue, driver pay, tow bills, and rush parts. A $400 PM service catches most of what causes that downtime. Beyond cost, well-documented PM records significantly raise resale value when you turn over trucks.
Depends on the engine, application, and oil used. Modern Class 8 trucks running highway miles with CK-4 oil typically go 25,000–35,000 miles between oil services. Trucks in stop-and-go, vocational, heavy idle, or dusty work need shorter intervals. I'll help you set a schedule based on your actual operation rather than a generic number.
Both.
Yes. That's the main way I work. I bring the tools, fluids, and filters to you. For fleets with their own facilities, I can work in your bay or outdoors depending on the weather and the work.
Date, mileage, fluids and filters used (part numbers and quantities), inspection findings, any items recommended for follow-up, and the next scheduled service date. This is the documentation chain you want if a CSA roadside inspection turns up an issue — being able to show consistent maintenance records matters.
I perform standard PM services. For OEM warranty work that requires a dealer (some early-life engine and after-treatment claims), you'll need to go through your dealer. I can do everything that doesn't require dealer-only authorization.
