    No, it was a cupful of diesel in your petrol to clean out summat, or lubricate you valves, or... maybe it was peeps with old lead head beetles. I really can't remember.

    we are talking yonks ago in old trucks that had pumps like a fire tender water pump !
     
  3. My mate whos a mechanic, when someone puts diesel in their petrol car he usually drains the tank into a big drum skim most off the diesel out and then puts the petrol into his older car, it usually coughs and farts for a bit but still runs ok.
     
  4. Id say 5 litres in 40 ;itres of petrol would give the fuel tank,fuel lines and carb a good clean out
    It may even shift some of the coking from the heads
    It will smoke like mad untill its gone though

  6. We used to light hexi stoves under landys in cold conditions for the same effect one under the fuel tank and one under the sump
     
  7. Off top of me head couple of pints neat through the carb ll give it a good clean. Smoke like a single mother though

    How will diesel through the carb clean it more than straight petrol
     
  9. Derve lifts the gum n crap thats left by petrol over time
    Its also great at lifting carbon build up and all sorts of muck
     
  10. What Para said.
     
  11. Actually if you put a tiny drop of diesel in 70 gallons of petrol you can run your diesel engine on it.

    According to homeopaths.

  12. I've done this loads of times! (I keep Jerry cans of fuel and sometimes get mixed up)
    It'll smoke a bit and run rougher but other than that it'll be fine. I put 50/50 diesel petrol in an old Honda and that ran until I could dilute it down with more petrol.
    When I was (even more) poor I ran my VW LT on 'magic mix' which was a concoction of diesel, petrol, heating oil, chip oil, used engine oil and anything else combustible. Mainly from draining tanks at the local scrappy.
    Yeah it ran rough and smoky but it was CHEAP! You'd be surprised what older motors will run on.

    lol i used to empty our deep fat frier through an old t towel straight into the tank on my old landy...... used to go to lidl for veg oil at 15p a litre and 50/50 it with a nice drop of cherry that was cheap running!
     
  14. Ummmmmmmmmm! I'm telling! ;)

    i'd never have 2 tanks, one at the back with a gallon of white and another under the seat with 7up in it. these days they can sniff red with a probe up the exhaust, years ago they just used to syringe a bit out of the tank.
     
  18. If I could lay my hands on my copy of John Muir's Bible I'm sure he actually recommends a bit of heavy oil now and then
