Petrol in diesel

emandem said:

i ahve heard that people used to put a bit of petrol in diesel, thought it was an lod wives tale, obviously not, i would have thought changing the fuel filter once the petrol is out would be a good idea? martyn

No, No - It's not an 'Old Wive's Tale' - it's more of an 'Old Trucker's Tale'.

Without added petrol or paraffin none of the buses in Kosovo would run to schedule in the wintertime.

When the temperature dropped to below -30 degrees C our Scottish Humanitarian Aid trucks were almost alone on the road - no-one else could get their engines started. The bus drivers managed but only after lighting old cardboard boxes under their tanks - not a good idea if you have a plastic tank!

I managed to obtain (at great expense from Austria) some of the proper anti-waxing additive made by Shell to be added to the fuel by the driver. it smelt to me just like paraffin.

The fuel filter wont need to be replaced as any petrol mistakenly added to the diesel by the OP will have gone straight through.

I assume it would be a good idea to keep filling up to full with diesel so he keeps watering down the ratio of petrol to diesel?

Why ? The petrol being less greasy than the diesel it cleans the filter element, so ...???
Sorry, see now Singvogel already responded on this.

when i worked on the spanners many years ago, we always changed filters when fuel was contaminated, petrol in diesel, and vise/versa

I would agree if it were diesel contaminating petrol - but petrol in diesel in this ratio should not create any problems.

I'm not saying you should put water in the fuel. He put 10% (6L) petrol in his diesel tank (60L approx). Taking an average of the "well mixed" fuel after using up 25% of his tank, he will have lost 1/4 of his petrol and 1/4 of his diesel. If he then tops up with diesel until it's full then taking averages again he'll have 7.5% petrol in his diesel. If he keeps repeating the refill after using 25% then he will be "watering down" the petrol in his diesel. Watering down is a saying, which refers to ratio reducing rather than adding water.

I did think that too but I thought I'd give him the benefit of my suspicion. There's always the chance some fukwit will go and read it and think putting water in is ok to do. There's many a tratterer lurking in the Freelander section...
