Frequently Asked



What is PM Service?

PM A service is also known as a “maintenance check-out” or “safety inspection” and generally consists of a safety check and lubrication as well as checks of key components such as brakes, lights, tire condition and inflation, and fluids. It also includes checking and adjusting high-wear components. The normal interval for “A” service is between 1,500 and 2,500 miles on light vehicles, and between 5,000 and 10,000 miles on medium- and heavy-duty vehicles.



Here are just a few important reasons you should commit to truck service:

Prevent Breakdowns & System Failures: Simply making a few checks to things like your battery, and arranging routine servicing, can prevent the cost and inconvenience of a breakdown or smaller hassles like having to jump start your semi truck.
Ensure Dependable Safety: If your truck isn’t well-maintained, it probably isn’t as safe to drive as it should be. You might even be legally responsible in the event of an accident.
Extend Vehicle LifeSpan: Treat your diesel truck well and it’s going to last longer between oil change intervals and other service intervals without needing complex repairs or a complete replacement. Outfit it with high-quality parts and accessories you can depend on.


How Often are pms needed?

PMs are performed on truck tractors based on mileage – usually every 10,000 to 15,000 miles, depending on the size and type of truck. For trailers, the frequency of service is determined by time rather than mileage.


How Many Miles Do Semi Trucks Last??

Want to extend your semi truck life to its maximum? Proper maintenance is key.

Keep your engine lubricated by getting regular oil changes, and try to prevent multiple starts which are hard on your engine.
Overheating can damage your engine quickly, so keep an eye on your exhaust and cooling systems. Have them checked over every year and if you notice anything unusual, schedule your service immediately.


What Type of pms are there?


This form of preventative maintenance involves inspection of all major engine and truck components: transmission, brakes, windows, tire tread and pressure, spots that need greasing, etc. The inspection itself takes about two and a half hours to complete. If any repairs or replacements need to be made—such as tire changes, replacement of windows or mirrors, etc.—these require additional time.


Wet PMs, involve re-filling fluids (engine oil, coolant, brake fluid, windshield fluid, etc.) in addition to all other inspections required as part of the Reg PM. Because of these extra requirements, Wet PMs take slightly longer to complete—about three and a half hours—and are required less often than Reg PMs. Like Reg-PMs, they are carried out at scheduled intervals by mileage or by time (usually every 10,000 to 35,000 miles for tractors).
