    Angry Diesel in Hardbody 2.4 petrol

    The idiots at the BP put 6L of diesel in the Hardbody today So I filled the rest of the tank up with 75L of unleaded I presume the diesel will not do anything in such small quantity ??

    I would drain it, the cost of a tank of fuel is much less that that of a new engine. See here - thanks to my friend: Google.

    And it is not really the attendant that is the idiot.

    Diesel wont cause any damage to your system, it will just lubricate & smell funny.
    But petrol in a diesel vehicle is a total mess,

    You will probably notice your engine oil level will go up a bit - yes dipstick oil level goes up. If ever you see your oil level go up on a petrol engine you will find your petrol contaminated 10% or more with diesel. It does not do harm as mentioned but the dipstick going up gives you a skrik!

    Question

    I am also interested as to where all the extra oil comes from. .. Fuel and oil are in two separate chambers.

    Here is my 2c.

    Many years ago, one guy (engineer nogal!) filled one of the company petrol Polos with diesel. Tank was 1/2 and it ended up with a 50/50 mix. On return after his 250km round trip, he complained to the mechanic about the vehicle being sluggish. After finding the cause of the sluggishness, he drained the fuel tank (naturally) as well as the oil. I asked him about the oil change, and his reason was…. With a high diesel mix in the petrol engine, there is a lot of un-burnt fuel (mostly the diesel) on combustion. Some of the diesel washes past the rings and ends up in the oil.

    Polo went on and on with many 100 000’s of happy kilometers.

    Hullo 4e. Sorry I did not pick up your query as to my comment. I read your general comments with interest as you are'nt a chicken either. I wondered how many would question this. I was technical in the fuel & lube industry for most of my working career & it had me going for a while. It really does happen if petrol is contaminated with 10% or more diesel. The contamination happens in pipelines, depot tanks, etc. Because diesel is a heavier fraction than petrol it does not burn completely during combustion and slowly but surely gets past the rings & into the sump. I appreciate it sounds far fetched but it is true. I had many an irate customer phoning me when petrol got contaminated. I will bet a bottle of ten year old on that comment!

    You telling me that the petrol and diesel separates in the inlet manifold after comming out of a carburetter and then goes down the side of the piston... don't believe that in a million years.

    You telling me that the diesel and petrol separates after comming out of an injector at a zillion bars and then separates in the inlet manifold and the diesel runs down the side of the piston.... do not belive that either.

    Sorry, just my 2 cents worth.

    I accept the fact that there will be separation in "pipelines, depot tanks, etc.", but I was wondering how this separation can happen if the mixture has gone through the pump, carb and/or injector nozzles?
    The "blended" mixture will be subjected to serious turbulent flow in the combustion chamber, and the intense heat of the combustion process should make it unlikely to create the opportunity to separate the heavier fraction from the lighter fraction. The petrol will burn the diesel part as well. When combustion occurs, the pressure will be high enough to ignite the diesel as well.

    I accept that there can be separation in the fuel tank, but that would make it unlikely to get the diesel to the sump (via the cylinder bores).
    If separation did take place in the tank, the pick up would pick up diesel (in stead of petrol) and the petrol engine would run badly on the 'diesel', if at all.

    I still fail to see how the diesel can find it's way into the sump.

    (I am fully aware of the diesel engine problem, where faulty injectors can allow diesel into the cylinders and thus into the sump).
