What’s The Role of Engine Oil?

Engine oil is the lifeblood of your truck's engine, and it performs several critical functions, including:

  • Lubricating moving parts.
  • Reducing wear and tear.
  • Cooling the engine by transferring heat away from the combustion chamber. 
  • Cleaning the engine by removing contaminants and depositing them in the oil filter.
  • Protecting the engine from corrosion.

All in all, setting up a proper engine oil maintenance regime is what can set you and your business up for success. Well-oiled diesel trucks tend to last longer on the road than their counterparts, without experiencing as much downtime.

The Importance of Filter Maintenance

Filter maintenance is equally important to your truck's health. Filters trap impurities and debris that would otherwise circulate in the engine, causing damage. There are various filters that you should keep an eye on, including air, fuel, oil, and hydraulic filters, and it's essential to choose the right filters for your truck and replace them at the recommended intervals. Our team at Quality Mobile Fleet Services can help you select and install the right filters for your truck.

Why Fluids Need TLC

Fluid maintenance is also crucial to your truck's proper functioning. The most common fluids that require regular maintenance are transmission fluid, coolant, brake fluid, and power steering fluid. These fluids need to be topped up and replaced at manufacturer-recommended intervals to ensure optimal performance and prevent expensive repairs.

We had a truck lose power at a receiver, and called them for assistance with a jump start. The mechanic was there in less than an hour and got our truck started and back on the road. Quick and efficient, would use them again.

Had excellent experiences with Dave and Jan at QMFS San Diego.  These folks care about their customers and back up their promises with solid mechanics that got one of my drivers back on the road and we have used them ever since when in the San Diego area weekly.

Jan and her lead mechanic were excellent.  They got our Volvo in the shop promptly and got it diagnosed and repair faster and less expensive than the other shops we were quoted.  I fully recommend their commitment to helping companies and people that are in need . Eric Z
