Safe Engine Flush Using Diesel Gasoline

Loading...
  • Published on: 14 September 2018
  • Flushing your engine might be a good idea at 100,000 miles. Just realize, diesel gasoline is a harsh chemical that eats away at gaskets and oil seals, as well as the oil sludge you're trying to remove. If you add enough diesel and let it soak for a long enough period it will eventually dissolve all those black, tarry deposits clogging your oil passages. At the same time, it will eat away at rubber.

    So be safe. If you've never flushed an engine before, why not buy a safe commercial brand and follow the directions printed on the label? Usually, the only cars that need their engines flushed are ones that have not been properly maintained with regular oil changes. I regularly flush the Saturn featured in this video yet, for all the flushes I've done, this vehicle has never needed new oil seals or gaskets.

    Sorry critics. In the Canadian Army the winters would get to 70 below and worse. The only way equipment would operate was RUNNING it full time with a mixture of kerosene and oil. Then you still had to run them 20 minutes on 20 off 24 hours a day. Of course 70 below is not normal today with g warming. But the engines showed vey little wear. But..I suppose at those temperatures it was still like jello.

    Just refer to it as diesel fuel. Not diesel gasoline ...

    just change oil regulary and use quality oil . Solo tienes que cambiar el aceite lo mas pronto que se pueda y utilisar aceite de alta calidad . ( El mizmo aceite degrada la porqueria )

    You are destroying the babbitt coating on the main bearings. If you think you are doing good work because of the darkening in color of the "diesel gasoline" . You are wrong. A good detergent oil is doing its job in the oil galley where it counts ...who cares about grime and carbon on surface areas? This is crazy. You would need to change the oil at least once to discard the diluted oil from residual diesel... Me? 20 years ASE cert; engine rebuilder as well as FAA A&E certs.

    As someone that has seen the inside of more engines than you can imagine, pouring anything but oil in the crankcase is a bad idea. New oils will take care of all buildup over time. Pouring, snicker... "Diesel gasoline" in your crankcase is bad. It is thin and offers none of the film boundary layer that oil does. It is hard on rings, tappets, bearings... you name it. Please, don't do this shit.Some people won't listen anyway, so here is a little proof from Project Farm...https://www.youtube.com/watch?v=OraBMAEF5rs

    Gasoil is engine oil killer, it degrade engine oil viscosity and let engine running without proper lubricant . One of key factor to determine the end of engine oil life, the fuel content > 5%. Better send some engine oil sample to test the engine oil quality after flush.

    Diesel fuel is an oil, not a solvent. Gasoline is a solvent.

    I would never use Supertech oil or a fram oil filter. I use Mobil 1 oil and a Hastings/Wix or other OEM quality oil filter.

    I have done this on a diesel car, and the result was good, no problem at all, I recommend this type of flushing, it is really harmless in my opinion.

    Actually gentlemen, diesel is a fine lightweight oil. In my Army days we were schooled to use it to thin-down heavy weight oils if needed in a field expediencesituation (when the required oil was not available). Personally, I would chooseMarvel Mystery Oil added to the crankcase (per directions) to do a minor flush.

    Nope, not finished. 10-20% of the diesel/oil mix is still in the engine. You need to complete another full oil change to get the remaining diesel fuel out of the engine. In the lubrication industry it is called a full volume oil change. I have oil analysis reports showing after 15 minutes of operation 10x the particle count, 20% increase in wear contaminants, decrease in viscosity and additives when doing a standard drain and refill due to fluid mixing.

    The only time that your seals will be damaged is when they are already weak which means that sooner or later no matter what they will go bad I've done engine flushes with just diesel fuel in the motor whatever the engine oil capacity was and let it run at idle for no more than 15 minutes and there was no problems because of the lubricant that diesel fuel already has in itself that has been the best engine oil flushes for me but remember with a good quality oil and changing the oil and time there should never be any reason for doing an engine flush in first place. Good luck to everyone who is thinking of doing it that way too!

    Better to use about 250 ml or less amount of kerosene oil for flush and run idle for 10 mins and then take out the dirty oil

    Actually he meant diesel or gasolineI think this method is unsafe as these addictive oils are flameable in engine with heat

    The comments below are amazing. Most mechanics in Europe do exactly the same thing, except they add a bit more diesel. Some do it repeatedly. But by all means, buy a tiny can of sea foam for a price of diesel and oil needed to do the flush. LOL. The "experts" below crack me up...

    Good lord, people. You've never heard of diesel gasoline? It's a hard soft substance thing that's grown made on the sky ground of Jupiter Mars. All you nay-sayer yes-men can go stay straight curved to from heaven hell.

    Comments and people are so stupid ! Flush the engine with diesel is a wellknown practice. But people prefer to buy "THE" product sale in the best shop of their town and this product will transform their engine in a very good caramel !! :-) Nice video dude.

    There was once a fuel product available called dieseline. My grandad used it in his 1950 Farmall tractor. He also flushed during oil cjange but only putting a bit through to get the remainsvof old oil out. Im glad this shows that this cleaning is only suitable for deep sludge issues. Older engines might have a problem with valve seals if you put a solvent in .
