Questions & answers

What is this product used for?

Cleaning a diesel engine's fuel system and injectors while also improving the fuel's cetane number, aimed at restoring lost performance, smoother running and easier cold starts.

How is it used?

Add to the fuel tank before filling up — it works as you drive, so no extended idling is needed.

How is this different from a standard injector cleaner?

This combines injector cleaning with a cetane boost in one product, whereas some cleaners focus purely on deposit removal without the cetane improvement — useful if you want both effects from a single additive.
