I was in a petrol station today filling up with petrol this guy on the next pump said he puts in half a tank of petrol and half of diesel, he then said he gets more to the gallon is he nuts or is he right? I did not notice if his car was diesel or petrol, it was a big Citreon.
Diesel contains more energy per unit volume than petrol but probably not enough to make it worthwhile at current prices and that assumes complete combustion. I once ran an outboard motor on paint thinners for an hour os so but that was out of desperation rather than economy.
It goes without saying I did not take him up on it, on my rounds as a postman one day I came across this chap filling up with bottles of cooking oil, he said it ran great but had a funny smell.
Years ago when diesel was much more crude than it is now a trick the wagon drivers used to stop their diesel going really gloopy in cold weather was to put a drop of petrol in it. Only a drop though, not half and half.
With diesel down to 98p a litre it is cheaper than cooking oil,but don't be tempted to fry your chips in diesel.
The guy was having a laugh, a petrol car will not run on a mixture nor will a diesel.
I do not wish to appear disrespectful to the man and I know you can't really tell but he did not look as they say a full shilling, but he did seem to use two different pumps.
A petrol car would stop immediately the desiel hit the engine. A diesel would most likely run fine but would damage the engine on s very short time, I have done it, accidentally and burned out the injectors and valves within a week.
I Aldo ran my VW camper on used chip oil for about 12 months, that ran perfectly, but always smelled like a mobile chip van from outside.
I have no intention of doing so RATTER15 it's just that he looked so genuine, I will stick to petrol as there is only one place alcohol is going in our house ;)
