Scheduled service to keep your trucks DOT compliant and running strong.
A DPF (Diesel Particulate Filter) captures soot and harmful particles from your truck’s exhaust to reduce emissions and meet environmental regulations. Over time, the filter can clog and needs professional service to keep your engine performing at its best.
A clogged or damaged DPF can cause:
Reduced engine power and fuel efficiency
Increased emissions and smoke
Warning lights on your dashboard
Potential engine damage if ignored
Regular DPF cleaning and maintenance prevent costly repairs and keep you compliant with EPA emission standards.

DPF Diagnostics: Checking filter condition and performance
