How Often Should You Change Heavy-Duty Engine Oil & Oil Filters?

The Threat of Dust Abrasion in Heavy Transport Engines

Trucks operating on dusty transport routes ingest massive volumes of air every minute. Standard paper filters clog rapidly and deform under high suction, allowing microscopic silica dust particles (10 to 20 microns) to enter combustion chambers.

Once inside, silica dust acts like sandpaper on piston rings, cylinder liners, and valve guides. Premium filters from Mann, Fleetguard, and K&N utilize multi-layer synthetic media that captures 99.4% of dust particles while maintaining unrestricted airflow.
