What is a car system cleaner?

If your car feels sluggish, then system cleaners could help.

When added to your tank, they can reduce emissions, improve performance, and make your engine feel as good as new. They also provide protection for the components in your engine, which can help it to last longer.

You need to make sure that the system cleaner you choose is right for your car, as the wrong additive could damage the components in your petrol or diesel system.
