Looking to safely and quickly clean your diesel fuel injectors? Revitalize your truck’s diesel engine with Diesel Injector Flush , a powerful, concentrated injector cleaner designed to remove the waxy, hard deposits that build up inside modern diesel injectors . These deposits commonly stick to critical internal components like the pintle, control valve, and armature, leading to poor spray patterns, rough idle, and reduced performance.

Formulated for today’s high-pressure common rail diesel engines, Diesel Injector Flush targets both internal and external injector deposits, including polymeric films, carboxylate salts, and carbon coking. The formula is enhanced with cetane improvers and lubricity additives to promote smoother, cleaner combustion, improve cold starts, and protect fuel pumps and injectors from wear during the cleaning process .

Diesel Injector Flush helps restore proper injector spray pattern, timing, and contribution rates. Removing deposits that cause injector imbalance can help resolve injector-related performance issues, recover lost power, improve fuel efficiency, and restore overall drivability!

Treatment Plan

Use Diesel Injector Flush as preventative maintenance during fuel filter service, or as a fix to restore performance when injector balance rates decline.

• Engines over 8 liters: use 1 gallon

• Smaller engines: use 1 quart (32 oz)
