Lucas Oil Diesel Deep Clean fuel additive — 16 oz bottle, reduces DPF regens & soot

Lucas Oil 16 oz Diesel Deep Clean is a fuel-additive treatment designed to reduce particulate buildup, lower exhaust backpressure, and cut the frequency of diesel particulate filter (DPF) regens.

Diesel Deep Clean is a Lucas Oil formula created to help diesel engines operate with fewer DPF-related interruptions by promoting cleaner combustion and assisting in the removal of soot already trapped in the filter. Sold in a convenient 16-ounce bottle, this product is intended for preventative maintenance and periodic treatment in on-road and off-road diesel applications. It’s made in the United States and is formulated to work alongside your existing maintenance routine rather than replace mechanical servicing.

How does Diesel Deep Clean reduce DPF regens?

Diesel Deep Clean alters fuel combustion characteristics so less particulate matter is produced during normal operation. With fewer particulates entering the exhaust stream, the vehicle’s DPF accumulates soot more slowly and requires fewer active regenerations.

• Promotes cleaner fuel burn to reduce soot formation
• Helps dissolve and loosen existing deposits inside the filter
• Decreases the frequency of temperature-driven regen cycles

Will it improve engine breathing and reduce backpressure?

By aiding in the removal of trapped particulate and minimizing new soot, Diesel Deep Clean can reduce exhaust restriction. Lower backpressure helps the engine run with less load, which often results in cooler operating temperatures and smoother response under load.

• Assists in clearing trapped soot to reopen exhaust flow paths
• Reduces strain on turbochargers and exhaust components
• Supports more consistent exhaust temperatures and engine efficiency

How and when should I use the 16 oz bottle?

The 16 oz bottle is sized for treating typical diesel fuel tanks as a maintenance dose. Follow label directions for correct dosing based on fuel volume; treatments are usually applied when refueling or at scheduled service intervals to maintain cleaner combustion over time.

• Pour directly into the fuel tank per label dosing instructions
• Use periodically as part of preventative maintenance—especially before long hauls or heavy use
• Compatible with most on-road and off-road diesel engines—check vehicle manual for specific restrictions

Is Diesel Deep Clean compatible with modern emission systems?

Diesel Deep Clean is formulated to be used with modern diesel emission control systems without altering their calibration. It is intended to supplement, not replace, recommended service and diagnostic procedures for DPFs, DOCs, and SCR systems.

• Designed to work alongside DPF, DOC, and SCR hardware
• Does not replace mechanical cleaning or professional diagnostics
• Safe for periodic preventive treatments when used as directed

Who is this for: Lucas Oil Diesel Deep Clean 16 oz is aimed at fleet managers, owner-operators, and diesel vehicle owners who want to reduce time lost to DPF regenerations, maintain exhaust flow, and help preserve engine performance between scheduled services. It's suitable for drivers of medium- and heavy-duty diesel trucks, agricultural equipment, construction machines, and any diesel-powered vehicle where particulate filter maintenance is a concern. For vehicles with persistent DPF faults or sensor failures, consult a technician—Deep Clean is a maintenance aid, not a diagnostic or mechanical repair.
