Petrol cans + diesel...

    I have several 1 gallon petrol cans left from when I was gardening (also from my Dad's old place).

    I was just considering using them for storing diesel, such that I might not have to go out on special trip to fill up.

    Which of these apply....

    a) should be perfectly OK

    b) ok if you swill out with diesel to start with

    c) atyour own bear the consequences

    d) on no account what so ever.

    (Thecans are perfectly dry now and don't smellof petrol at all)

    No need to swill them out, but do make sure that there isnt any other fluid left in them.. Traces of petrol will be fine, but open and attempt to pour them out first.

    in light of this, you will be fine.

    small amounts of Petrol in a Diesel engine are fine anyway, in fact in winter or really cold climates it's suggested 5% per full tank will help it cold start. I used to do it with my old Escort that struggled a bit in winter, never caused any problems.

    The guy I rented a room off once put diesel by mistake into his 1300 essy mk3(petrol).

    That aas back in the late 80's and we weren't so used to having a mix of diesel and petrol pumps.

    The engine didn't like it a bit and he eventually had to drain it off.

    A small amount of petrol in diesel is diff tho' i guess.

    I'm afraid you are wrong there Matt,in the old days you could get away with a small amount of petrol but do that in a modern engine and it can be catastrophic.
    Depending on manufacturer there are different price structures for parts needed,ranging from wrong fuel put in nothing done-ie key not turned in ignition,to concking out without realising your mistake,in some cases the bill runs into thousands!!
    You have been warned.

    Mercedes used to suggest up to 30% (!) petrol for extreme cold in their diesel engines, not sure if it's still in the handbook. A mate of mine who I used to work with said it was still in his handbook for his 02 plate E320CDI, not sure on brand new stuff.

    David, provided your cans are clean then you can put diesel in them. The odd drip of petrol well mixed in with diesel won't harm anything. Damage to some diesel engines is the result of either lack of pump lubrication (petrol is less oily than diesel) or solvent action of petrol on some pipework seals. Remember that there is no fundamental difference between petrol and diesel, they both come off the same distillation tower (albeit at different heights) so there will inevitably be traces of petrol components in diesel and vice versa. Only if you have too much is it a snag, and for your Tranny Connect the engines aren't that choosy.

    On a modern engine even if the ignition key has not been turned,at best the tank needs draining most garages now change seals and sometimes fuel lines.

    I wrong fueled my Alfa 156 with 1/4 tank of Petol about 2 years ago, I completed the fill with Diesel and just drove reasonably carefully until the next on 198,000 KM and driven with complete abandon issues at all..starts, runs, no smoke or bad stuff still ok.and before I get all the posts I know that Diesels rely on some lubrication within the fuel for the pump etc, but a one off is no problem.

    IMHO you were lucky,i would assume your car is over five years old,as far as i know most current diesel engines would req the action i stated,the scale i referred to i believe was from Land rover with their diesel engines where a simple tank drain to full injector/pump/lines and in extreme cases tank swop result.

    Yup, you are correct Stevie, it is now nearly 8 years old to be precise..:)

    The problem is that hundreds of people a week miss-fuel,it's getting better with warning stickers and correct fuel caps but accidents occur only too often.

    You are correct!!!
    There were 4 grades of petrol and the then smelly diesel!
    There are usually no more than 4 nozzels on each pump and by and large petrol is green and diesel black,but these "Super fuels" are sometimes on the black pump-no wonder theres so many problems!!!

    Again my uncle did this once(diesel into a petrol tho'), again back in the '80s when we were getting used to diesel on the forecourts.

    In this case he was pretty annoyed that the pumps weren't very well labelled and got the mechanics to drain it off (on site IIRC).

    I'm terrified of doing this with mine.

    Thanks for all the posts.
