Poor quality of fuel is becoming more of a challenge by the day, particularly if you travel outside RSA. Grit, algae, rust and water are the chief culprits damaging our fuel pumps, clogging filters and wrecking injector jets.

One way to minimise the problem is to filter all your fuel while you fill up. How?

Simple - buy a leather chamois, rinse it out, let it dry and then fix it to the mouth of a large funnel. Run the fuel through the chamois. It WILL take out all the water, algae, rust and grit. This is standard procedure when pumping aviation fuel from drums into planes. You will be amased how much water comes out of your fuel tank if you drain it every year! :eek:

For years I have carried a chamois "filter" with me. Petrol attendants get a bit annoyed because it takes a little longer to fill up with a small funnel (250mm diameter). I have thanked the chamois many times for catching all the rust out of my old jerry cans, stringy bits of plastic out of incorrect plastic cans used by "bush fuel vendors" up north. One 20lt plastic can of petrol in Zim yielded nearly FIVE liters of water! :mad:

Try it with a half litre of petrol mixed with 250ml water and some grit, sand.  Run it into a clean clear container and see for yourself how much of the 250ml water stays in the chamois. ;)

Here's the drill in pic form:

  • Chamois in funnel- I stitched mine to a band with elastic in it to fit different funnels
  • Bottle of water with a few drops of food colorant in so you can see it in the pics
  • Water going into about three liters of petrol
  • All shook up and poured into jerry can no2 through the chamois filter
  • Check the water staying in the filter as the orange fuel on top runs through
  • All the water stayed in the filter

  • Water poured back into the same jar - all there 100%
  • Plus some algae in the fuel that had been stored in the can for about eight months is trapped in the chamois

"why does the petrol go through and not the water?"

Good question!  Chamois is goat skin. It Can seep water on it's own but as soon as it is FIRST wet with petrol it becomes water repellant. Goat skins that are tanned and turned inside out, then rubbed with olive oil, have been used for thousands of years to carry water, milk, cream and wine in. Ref the Bible.

When pumping avgas, even with the high quality filters used in the fuel depot bowsers, I have still pulled water from the avgas with the chamois filter. So always had one in the plane. That lousy smell of avgas/petrol  you sometimes get in small planes......  yip it's the jolly chamois stinking in the back somewhere. The smell sure trumps an engine out due to frozen water in the carburetor!
Took me a while to work out that putting the filter in a can fruit jar that seals well stops the petrol smell in my plane / car. Never use a tin can! the fumes will be under pressure and when your wife opens it to put the fuel in while you enjoy a cold frosty.....
               ..... it may generate a spark!  Ja well no fine....

Yes, genuine chamois are available at Makro, Builders Warehouse and most Auto Spares places. Try to find one that is about 400mm x 400mm. Not cheap... about R 60.oo

I think I'm going to test this and see just what is in the petrol form a normal garage.

Hopefully nothing but petrol

How dos one know the difference between genuine and imitation chamois..?

Bushdriver R60 is not exactly expensive if you compare it to being parked in middle of nowhere without clean filter either :P

Thanks for the advice it will go a long way

Genuine chamois is very soft and dry when new, one inserted in water it is uber soft and has toi be wrung almost dry before working - it cannot be left wet like the Kanebo, otherwise it rots away, so you dry it out between washes and then soak before use.

The plastic ones all have layers, and are happy to stay wet - love the smell of a new genuine chamois pure leather delight!
