Now as we cleared the basics and learned what injectors are doing in the internal combustion engine. Let’s now focus more on the dirty fuel injector symptoms.

Well, this will be the case if you have an unbalanced spray pattern. Imagine that your fuel injector is spraying inconsistently. After that, we covered the diagnostics process and the cleaning process. Lastly, we discussed the costs involved in sorting this problem out permanently. F.A.Q Technically you can drive with bad or dirty fuel injectors. But for how long that depends on the extent of the damage to the injectors. Direct-injected engines differ from standard, or manifold-injected, engines by squirting gasoline directly into the engine's combustion chamber rather than spraying it in the intake tract. Direct-injection engines are touted for providing better performance and fuel efficiency, and they have become increasingly prominent over the past decade. Even if a fuel injector cleaner isn't also a fuel stabilizer, it's still OK to leave it in your tank for extended periods of time. "Generally speaking, however, even if you use a particularly strong cleaner, you just pour it into the fuel reservoir," says Rosato. "If you don't use your vehicle the cleaner is just going to stay there in the reservoir and do nothing 'actively.' So, unless you're pouring lava into the reservoir, you can just relax. The worst that could happen is that the cleaner goes stale and becomes useless after quite some time. Nothing to be worried about."

How often do you need to use diesel injector cleaner?

Even with the proper tools, professional fuel injector cleaning equipment and specialized ultrasonic cleaning solutions it still takes us here at Injector RX about 45 – 60 minutes to properly clean a set of injectors. (More if the injectors are particularly clogged / dirty.) A. Our advice would be to use a fuel injector cleaner on every tankful. If you strictly use premium fuel at every fill-up, you can probably reduce this to every second or third tankful. Standard fuel has a much lower cetane than that of it’s premium counterpart and has been known to create oily deposits within the fuel system so we would definitely advise using a fuel injector cleaner at every fill-up if you often use standard fuel. STP® Diesel Injector Cleaner can be effective within 50 miles, helping to restore diesel engine performance, smoothing out rough idle and reducing fuel consumption and exhaust emissions. What are the benefits of using diesel injector cleaners? All these components are affected when the car is running rich and drinking a ton of gasoline. And frankly, they are really expensive to fix. That’s why clean the dirty fuel injectors and solve your problem before this issue becomes too expensive. 6. Smell Of Fuel

Do you want a fuel system cleaner or a fuel injector cleaner? Again, fuel system cleaners are typically stronger since they need to clean all parts of the system, but fuel injector cleaners are usually cheaper.And based on these clues, you can search for your problem. So, if you get a P0305 code, it means that cylinder number 5 has some kind of misfire problem and this could be attributed to a bad spark plug or dirty fuel injectors. 4. Engine Hesitation And Surging Rough idling with excessive shaking, jerking or vibration when the engine's running but the vehicle isn't moving
