241. Top Tips Tuesday - Out With The Old, In With The New

For a good few years we have been singing the praises of Grotamar, the diesel fuel additive that helps prevent the dreaded diesel bug. We first mentioned this product back in my blog of October 2010 and since then we have used it ourselves on our own craft and sold it to a variety of users like the local truck service centres, domestic central heating oil suppliers and a number of farmers as well as scores of powerboat and sailboat owners. We were, I must confess as they say in footballing terms, ‘gutted’ when the importers of this product advised us that it would no longer be available for retail sale in the UK.

November in Amsterdam for a lot of the marine trade means METS, and to this huge Marine  European Trade Show (almost 16,000 exhibitors from all over the world) went our commander in chief Andy armed with a load of missions including ‘find a replacement for that excellent product Grotamar’ After three hard days of foot slogging and the occasional Amstel in the evening he once again landed on these shores, this time with his passport, wallet and loads of technical leaflets with him,  but that’s another story. Marine 16 Ltd was a company that caught his eye and it’s a British company to boot, which makes a pleasant change. They have, in their own words, been ‘bringing the most comprehensive range of fuel treatments on today’s markets.’ Yes I had heard of them and they had an excellent comparable product to Grotamar according to Practical Boat Owner but as the saying goes ‘if it ain’t broke don't fix it’ so we never stocked it. Well with our supplies of Grotamar now well and truly dried up, we are now stocking the complete range of Marine 16’s diesel fuel products. Incidentally the guys at Marine 16 are ‘proud to supply the RNLI’ what better recommendation do you need!

If you are confident that your fuel is ‘bug’ free Diesel Fuel Complete is the additive to use. The important benefits from using this maintenance product are:-

 

  • Stops diesel bug
  • Cleans injectors and filters
  • Fuel complete bottle
  • Protects fuel pumps
  • Contains antifoam
  • Demulsifies water from fuel
  • Increases cetane rating
  • Gives easier starting
  • Improves fuel consumption
  • Reduces smoking

 

If you think your diesel fuel supply may have an issue with the dreaded bug, we do sell at a very reasonable cost a Marine 16 Ltd Diesel Bug Testing Kit and can be used to check for microbial contamination of diesel fuels in boats, storage tanks, home heating fuels etc. It is easy to use and can of course put your mind at rest if you think your fuel is dodgy!

Diesel Bug is the boating name given to the organisms that forms slime in diesel fuels. Diesel bugs are, in fact, microbial organisms and come in three main varieties where fuel spoilage is concerned. There is bacteria, yeasts & moulds in case you were ever asked at a sailing club quiz night! They feed on water, hydrocarbons and nutrients in the fuel and, if present, form a slime in the fuel and on the sides of the tank which, when disturbed, such as in rough seas, blocks fuel filters which often leads to engine failure. Regular users of Grotamar will be delighted to learn that Marine 16 has the same active ingredient and not surprisingly, produced very similar results and in a Practical Boat Owner test conducted some months ago Marine 16 performed as well and slightly better in filtration test results. In the PBO decontamination trial it gave a complete kill after just three hours and came top of the list  for filterability. Marine 16 not only prevented microbial growth but killed inoculated microbes to below detectable limits after 14 days.

You may ask how does the dreaded diesel bug grows? Well its impossible to prevent microbes entering fuel tanks and systems however the presence of water is a key factor in determining the rate and extent  of microbial growth so to help prevent Diesel Bug we would suggest investing in the brilliant Mr Funnel. Not only will it prevent dirt and debris entering the tank but its built in filter is so clever that it does not allow any water present in the fuel to pass through! What Mr Funnel cannot do though is stop condensation, so don’t forget to keep your tanks topped up, especially in winter!
