LIQUI MOLY Marine Super Diesel Additive

I haven't used the product yet,

by Myriam F.

Works Do not believe that by putting this product you will notice a radical change in the engine and it will run or get more CV. But what is noticeable is that the engine works better, less smoke, better starting, more "sweetness" of sound. Even if it still pulls 11.5 kN more. I will buy it again for sure

Good. Everything fine

VW Marine Time will tell whether it does what it promises. I have a 600 litre tank in the boat that it was designed to protect.

Great Marine Diesel Additive!!!

I've been using this product for quite some time now and am still impressed with the quality. Even after the long winter break, the diesel in the tank is perfectly usable. I'll definitely buy it again!

Diesel additive engine runs smoother and better combustion

Does what it's supposed to and hopefully protects as stated. What's striking is the clean combustion.
