Marine 16 Diesel Treatment Diesel Fuel Complete DFC, 100ml, 500ml, 1 Litre

This is a superb product, I use it every time I fill my Narrowboat, protects the engine and Eberspacher heating system, not cheap but far cheaper than a major breakdown and fuel system clean.

Fantastic product that will use every time I refuel my narrowboat When carrying out an engine service the pre filter and main fuel filter were absolutely clean more than 500 engine hours since they were installed

Had been having an intermittent splutter with my narrow boat engine when going for a few more revs. Had the diesel cleaned then added the marine 16 (100mil) to a full tank of fuel. Run for 30 minutes or so and heard engine getting quieter and smoother. It's now running like a top through all speeds without the miss. Bought enough for 5 top ups so worth the investment.

I've added it to my fuel tank, and nothing seems to have gone awry. I can only assume it's doing its job.

Good stuff no problems with filters clogging up. The item arrived on time and will be using the product in the future.
