    I have a different question. If, for example, with the amount of 60 l, there were 6 l of diesel, could it harm the gasoline engine? Should nothing happen because it is only 10% of the oil content in gasoline?

    It probably depends on the car. The older the structure, the better it will probably endure. I remember once my father and I had such a situation in a Skoda Favorit - my father started to pour oil out of his haste (he drove a diesel every day), he realized when he filled the tank in 1/4 of its capacity. So we poured the rest of the tank right under the cap with gasoline. Well, the car drove, although it had a large mule, but it did not negatively affect the later work of the car. After refueling with clean gasoline, it drove normally.

    How did he pour the diesel (large diameter gun) into the gasoline (small diameter bore)?
    If the ON content is too high, the engine will not start or will stall quickly.

    Let it pour :) "" ladies, but I was pouring something for a long time, it bounced and bounced "" quote from a client pulled "on a string". Candles will throw syfem, it's not worth driving like that.

    If it poured, it means that it was possible. I don't know much about refueling ON/Pb fuels, because I drive on gas every day (I fill up with petrol once under the cap and it usually lasts me 3-4 months, so I don't look at regular distributors too often, I never have an abscess I didn't refuel). Anyway, if people flood the tanks with other fuels, it means that somehow it can be done.

    It won't hurt anything, at least it won't burn or it will be weak...
    As for the strange statements "the engine seizes, explodes, damages, etc..." these are some extreme accidents of engines that were already on the verge of disintegration ....
    So there is nothing to read and believe in motors, autoworlds and online mechanics...
    If such a situation occurs, it is enough to drain the fuel and pour fresh, and the mixture up to 10% DOES NOT bother ...

    Petrol cars have flaps in the tank and you really have to be dumb to pour drop by drop.

    After all, it's logical that if you think it's either a full tank or something wrong.

    As soon as it fires normally, you can drive safely. You can't just leave it like that for a long time because the gasoline will separate from the drive and then there may be a problem.
    @D.J. ANNUS Sometimes it bounces like the "gun" is damaged. I haven't had that once.

    It will flip calmly
    The side effect is a bit of smoke and a difficult start on a cold engine

    Besides, it shouldn't be a problem unless you have some FSI, I wouldn't risk it.

    WELCOME. One of my friends wrote, the older he is, the less he will feel. Maybe what I write is off topic. In 1975 I found a job in a company where I had access to acetone. I "farmed" 4 barrels, i.e. about 800 liters. At that time, I had the Volga, probably gas 21, the old one. A hard winter came. but the engine withstood it. There was no trace left on the engine. Merchants struggled over it. Regards. ANDRZEJ

    I used to drive on a mixture of gasoline and diesel, poured from a diesel tank into which someone poured gasoline, but I don't know what proportions because I got it for free, but it smelled more like gasoline than oil. There was a problem with starting a cold engine and knocking combustion. If you hear strange noises from the engine when you press the gas, it is knocking combustion. But the worst problem is that the spark plugs get clogged after a while. And what's interesting, all the candles suddenly zasyfiły at the same time that suddenly it was impossible to start the car.

    You can burn that much with no problems. I wouldn't be writing here if I wasn't interested in the situation found yesterday at the gas station. Passat B6 tdi stands next to it, two batteries, hoses, bulbs and 3 men. I ask what are they doing? The owner filled up with 47 liters of Pb. He freaked out as the car ignited and then died. Do you think it still fires? From the tank extracts as much as possible from the filter just poured out at me. I had no time to wait for further developments. It was cleaning the fuel system right at the distributor.

    It will start, but the pumps may then fail over time.

    This... An old, primitive engine will last, but a newer, strained one (a lot of horses from a small capacity) can quickly finish knocking combustion.

    The point is probably that gasoline with the addition of ON has a lower octane number than uncontaminated gasoline. A lower octane number means more susceptibility to knocking. Currently, engines are designed to run on gasoline with a minimum LO of 95, although the newer ones probably prefer 98 LO. So using a low LO fuel will cause engine knocking problems.
    I still remember that old cars were probably adapted to LO 86 fuel, maybe that's why old cars cope better in such cases.

    In the Astra F from the early 90s, I have such a "myczek" at the engine controller, which is probably called "octane corrector". And you can probably use it to program one of the three octane numbers of the fuel on which you drive.

    It's not that diesel burns knocking in the cylinder from the spark plug, but that gasoline contaminated with oil will ignite from the spark plug prematurely. HE does not burn, but its presence reduces the LO of gasoline and that is the problem.

    It doesn't burn and goes into the oil. Two friends rode on such a compound.

    It will hurt in the long run. It will immediately hiccup and snort, and in a longer period of driving on such fuel you will have more goods on the oil dipstick in the engine. This fuel is suitable for a lawn mower.

    It's 99% fuel drained from a diesel where someone filled up with gasoline. THERE IS NO POSSIBILITY TO PUT A GUN FROM DIESEL INTO PETROL.

    Currently, there is no such possibility in cars, but let's take into account, for example, the cinquecento from the beginning of production, the year 93 includes both ON and Pb. I used to have one and it fit.

    Today, by mistake, I poured 8 liters of diesel from the canister into petrol, then I added 35 liters of Benz, so far I have driven 30 km and nothing is happening. Will it burn out such a mixture or is it better to drain it. Car Ford Fusion 1.4 Benz 2008 year

    https://www.elektroda.pl/rtvforum/topic3938304.html exactly the same topic, nothing will happen with such a small percentage of oil in gasoline, besides, nothing will happen to a petrol engine even if it is full of oil, at most it will not ignite, or it will smoke terribly, after draining and pouring gasoline it will continue to be normal

    you have to worry when you pour a lot of gasoline into the diesel, because the injection pump is lubricated with this oil, and without proper lubrication, it blurs, filings and the entire fuel supply system gets stuck

Topic summary

Mixing 6 liters of diesel with 60 liters of petrol in a gasoline engine generally poses minimal risk, particularly in older vehicles. Users report that while the engine may experience difficulties starting and could produce smoke, it typically continues to operate without severe damage. The main concerns include potential clogging of spark plugs and knocking combustion due to the lower octane rating of the contaminated fuel. Draining the mixture and refueling with clean gasoline is recommended if issues arise. Newer engines, especially those with higher performance specifications, may be more susceptible to damage from such mixtures. Overall, a 10% diesel content is often considered manageable, but caution is advised for prolonged use.
