About oil & filter change.
Regular oil and filter service is the simplest way to protect a diesel engine. A mobile oil change lets the work happen in your yard or at a customer site instead of taking the truck off the road.
A mobile mechanic can look at the unit where it stands, whether that is the roadside, a yard or a jobsite. That can avoid a tow and shorten downtime when the fault is suited to on-site work.
Part of Heavy-Duty Truck Repair.
When you might need it.
Any of these is a good reason to call and describe what the unit is doing.
Service interval reached on the odometer or hour meter
Dark, thin or contaminated oil on the dipstick
Oil pressure warnings
A fleet schedule that needs yard-side service
What the service involves.
Draining and replacing engine oil
Replacing the oil filter and, where applicable, other service filters
Checking for leaks and visible wear during the visit
Recording the service for your maintenance log
Causes and good habits.
These are possibilities, not a diagnosis. The only way to know is to test the unit.
Possible causes
- Service interval reached
- Fleet schedules and extended drain intervals
- Contaminated or diluted oil
Practical tips
- Keep service records for each unit
- Use the oil grade your engine maker or fleet specifies
What to expect.
Oil specifications vary by engine. Provide the make, model, year and any fleet-specified oil so the right products are used, and we will confirm what can be handled on site.
On-site repair depends on the fault, parts, vehicle condition, safety and service feasibility.
