How to clean diesel injectors: complete guide with professional additives
Diesel injectors are among the most delicate components of the engine. Carbon deposits build up, reducing combustion efficiency and causing increased fuel consumption, exhaust smoke and loss of power.
Symptoms of dirty injectors
- Fuel consumption increase of over 10–15%
- Black or grey exhaust smoke
- Loss of power during acceleration
- Rough idle
- Difficulty starting from cold
The solution: tank-added cleaning additive
Pro-Tec Diesel System Super Clean dissolves deposits and burns them off in the normal combustion cycle — no dismantling required.
- With the tank nearly empty, pour the entire bottle (375 ml)
- Fill up as normal
- Drive 30–40 km on a motorway
- Repeat every 5,000–10,000 km as a preventive measure
