While most of my 4WDs are diesels, I’ve had my fair share of petrol powered trucks in the past. We see plenty of them through the workshop thanks to their lower purchase price and higher power levels, which as we know is ideal for sand work.
All fuel systems, particularly those on 4WDs, are subjected to carbon and sediment build-upwithin lines, injectors, throttle bodies, spark plug tips and, for those older petrols, the carburettor. It’s a gradual process that can inhibit performance enough so that you won’t notice it occurring, but will ultimately reduce power and increase fuel consumption.
One area where it’s particularly damaging is on your injectors. As our engines rely on the fuel to be injected in a precisely metered volume and spray pattern, having carbon CLEANING YOUR INJECTORS COMPILED BY GLEN HADDEN build-up can affect how much fuel is introduced to the combustion chamber and the atomisation of the fuel – leading to rough running and an inefficient burn. By running injector cleaner through your fuel system, you’re effectively removing this build-up and ensuring your vehicle will run optimally.
Running an additive such as Liqui-Moly’s Fuel Injection Cleaner through your engine every 2000–5000km ensures your injector’s spray pattern is as exact as when the engine was new and running as efficiently as possible.
Opting to run a liquid-based injection cleaner is a cost-effective way to prolong the service life of your engine, and it’ll also maximise time between services. While this may not seem like much at first, we all know running a 4WD can be expensive, so the savings really do add up over years of ownership.
Some people are sceptical when it comes to liquid additives and cleaners, but I’ve used the Fuel Injection Cleaner in my workshop for about six months now, and have been running it periodically through a few different 4WDs. I can safely say that it really does make a difference to the performance of the vehicle, not to mention it’s a hell of a l to cheaper and easier than an injector replacement!
