Superb product
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.

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

It actually works
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.

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

Does what it should
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

Diesel Bug Treatment at a great price
Popular choice and gets good reviews. Much better price than the Chandlery.

Not as advertised on photo
Was after the 1lt diesel bug treatment as shown in the photo, not realising the description was for the diesel fuel complete. So beware when purchasing

The answer to increasing reported problems with Bio diesel?
I've used Marine 16 for many years and have never had a problem with Diesel bug, year after year filters are clean when changed at an annual service. Like many I've had concerns over the increase of the percentage of bio-ethanol in diesel and have heard reports of an explosion of diesel bug problems because of this. The diesel fuel complete promises to eliminate the problem of a higher water content promoting bug growth and clean the injectors and bores as well. If it's as good as the Marine 16 I will be very pleased. Good seller, rapid dispatch and UPS delivery.
