JLM Gasoline Direct Injection (GDI), TSI, TFSI Petrol Injector Cleaner, 250ml

Modern GDI engines are known for problems with the coking-build-up of cooked fuel deposits. These GDI problems are mainly caused by the higher cylinder temperatures and pressures released into the crankcase which accelerate oil vaporization.Eventually this causes oil droplets to coat the intake valves and injectors. The location and angle of the fuel injectors in GDI systems mean that fresh fuel is not sprayed onto intake valves, so it doesn’t “clean” or cool them by preventing vapour build-up.As a result, this build-up can accumulate and bake onto intake valves and injectors in as little as 16,000 km (10,000 miles).Using a fuel without optimized GDI additive technology is likely to lead to fouled injectors and compromised critical engine efficiency. Engine performance drops, fuel economy falters and emissions rise.How to use JLM GDI Injector Cleaner.
