Diesel Fuel System & Engine Cleaning
Restore diesel performance. Clean what you can’t see.
Diesel engines are built to work hard — but over time, deposits build up throughout the fuel system, injectors, combustion chambers and engine. Those deposits affect the way your diesel starts, idles, accelerates, burns fuel and produces power.
This isn’t simply adding a fuel additive and sending you down the road. It’s a professional diesel cleaning service performed with specialized BG products, equipment and procedures.

Diesel Injection Service
Clean the injectors. Clean the combustion chambers. Restore performance.
Diesel fuel injectors operate under extreme pressures and require precise spray patterns for proper combustion. As carbon and fuel deposits accumulate, spray patterns distort — the result can be incomplete combustion, hard starts, rough operation, reduced power and decreased fuel economy.
The service begins with professional diesel fuel system cleaner in the tank, circulating through the fuel system. Our technicians then use specialized BG diesel injection cleaning equipment to deliver a concentrated cleaning solution through the engine — restoring injector performance and combustion rather than simply treating the fuel in the tank.
Recommended approximately every 15,000 miles, or sooner under extreme operating conditions.
Intensive Cleaning Of:
- Diesel Fuel Injectors
- Injector Tips & Nozzles
- Combustion Chambers
- Fuel System Deposits
- Carbon & Combustion Deposits
Is Your Diesel Showing the Signs?
- Decreased Fuel Economy
- Loss of Power
- Rough Idle
- Slow Throttle Response
- Hard Starting
- Poor Engine Performance
Diesel Engine Performance Service
Your diesel’s fuel system isn’t the only place deposits build up.
Deposits inside a diesel engine can interfere with piston ring operation. When rings aren’t functioning properly, compression suffers and excessive blow-by can develop — reducing performance and fuel economy. This service attacks the problem from multiple directions.
- 1
Engine Performance Restoration
A professional engine cleaning product is added to the crankcase and circulated through the engine before the oil change — designed to dissolve and suspend deposits in the old oil so they drain out with it.
- 2
Fresh Oil Protection
After the old oil and suspended deposits are drained, fresh engine oil is installed along with a professional diesel oil conditioner that helps maintain oil performance under demanding diesel operating conditions.
- 3
Fuel System Cleaning
The service is completed with a professional diesel fuel-system performance treatment in the tank, circulating through the fuel system to help clean deposits and maintain smooth, efficient operation.
When Should You Consider It?
- Poor Fuel Economy
- Loss of Power
- Sluggish Engine Response
- Excessive Smoke
- Diesel Engine Deposit Buildup
- Excessive Blow-By Related to Deposits
- Heavy-Duty or Severe Operating Conditions
Recommended Intervals
Diesel Engine Performance Service — every 10,000 miles, or as part of regular oil-change maintenance.
Diesel Injection Service — every 15,000 miles.
Sooner for vehicles operating under severe conditions.
Why Diesel Deposits Matter
A dirty injector isn’t just a dirty injector.
Modern diesel engines depend on extremely precise fuel delivery. Deposits alter an injector’s spray pattern, which affects how efficiently fuel and air burn in the combustion chamber. And deposits aren’t limited to injectors — they affect the fuel system, combustion chambers and internal engine components, contributing to problems with performance, efficiency, starting, throttle response and smoke.
Keeping a diesel clean can be just as important as keeping the fluids changed.
What Can You Expect?
Restore Fuel Efficiency
A cleaner fuel system and proper injector operation can help the engine use fuel more effectively.
Restore Power
Removing performance-robbing deposits can help restore lost engine response and power.
Improve Throttle Response
Cleaner injectors and combustion chambers can contribute to more responsive engine operation.
Improve Engine Performance
Proper fuel atomization and combustion are critical to smooth, reliable diesel performance.
Promote Longer Engine Life
Preventive maintenance and deposit control help protect the significant investment you’ve made in your diesel engine.
Especially Valuable for Working Diesels
Diesel trucks don’t always live easy lives. Towing. Hauling. Idling. Short trips. Job sites. Dust. Heat. Long hours. These conditions are hard on an engine and its fuel system — which is why this service makes particular sense for diesel pickups, work trucks, fleet vehicles, service trucks, commercial diesels, towing vehicles and high-mileage diesels.
Operating multiple diesel vehicles? We can incorporate BG diesel services into a preventive fleet maintenance program.
We Don’t Throw Parts at Problems
When a diesel isn’t performing correctly, we combine our advanced diagnostics with professional BG diesel services to determine what’s actually happening. Sometimes a component has failed and needs repair. Sometimes the system needs professional cleaning. Knowing the difference saves you money.
Clean it. Protect it. Put it back to work.
