to use injector cleaner?

I heard that the wurth brand cleaner is good, but it is necessary to use it? How many times should it be used annually?

useful, cleans oxidation in the injector, protects it. There is no harm in using it once a year. You will add and use all injector cleaner to your vehicle where you fill the full tank gasoline. You do not need to change the filters or oil to use this product. If it's time, you will change it.

Meanwhile, one of its biggest features is that it mixes with gasoline and other wastes other than gasoline and other wastes left at the bottom of your gasoline tank and allows you to clean your tank. when you finish a tank gasoline with this product, it provides a clean tank and a clean injector.

I was not wurt, but I used a product that was in service, I was very satisfied.

I remember that there were people using the forum, I have never heard of a problem person

I also used it, there is no problem, I even have to use it. Even though it may be clean at the gas stations, you may have come across water mixed fuel, or the drops of water flowing from the water in your car may accumulate in the rainy days in time, the water accumulated in a round can be drawn into the injector while the light on the gasoline indicator lights up. this product mixes those gases with gas and allows them to be burned.

It is beautiful then, there are also boron-added cleaners here, and if I am not mistaken, there is also the würth brand. Let me use it then it's worth my car
