Safe Engine Flush Using Diesel Gasoline

  • 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.

    Way back before all the magic of chemistry We used to put in one quart of diesel, starting with a hot engine and we were usually down a quart anyway, run it for a couple of minutes and then change oil and filter. Not sure how good it was but We were usually way over on our change.Remember We were young, dumb and broke.

    Diesel is a light oil , flushing out an older car engine with it won’t harm it if done right , 1 drain old oil remove filter, 2 new filter 3ltrs diesel start engine Don’t rev run for 5 minutes switch off, leave for another 5 minutes drain remove filter. Then refill with fresh oil and new filter, Been doing this for 40 plus years never damaged an engine yet .

    A guy driving a Pontiac VIBE and calling diesel as diesel gasoline, I would never trust this Hillibille even to bring my MCdonalds french fry delivery and let alone an engine

    Why not use something safe for your engine like ........Seafoam! Add a bottle (follow the recommendations) to crankcase and drive around a couple days prior to oil change. Also add some to gas and it will keep carbon from building up.

    For an older engine that hasn't seen regular oil changes in a long time this might be ok. I had a 57 Willys Jeep that saw nothing but non detergent oil. I did this several times as the engine was so gunked up it wasn't funny. What I got out of the engine was unbelievable. Would I do this to a properly maintained vehicle? Not on your life unless it was severely neglected.

    The fact that you’re using a FRAM filter tells me everything I need to know. #garbage

    Never flush an engine. If it’s been serviced when it should have been then there should be no problems to begin with. If its a poorly maintained used car then you should not have bought it.

    Just run Royal Purple for about 1500 miles and a GOOD oil filter then change out. Pull your valve cover, you’ll be impressed. Then use your oil of choice for regular intervals. I personally like Castrol Edge Synthetic. I have to run 0w-40 and I find it better than Mobile 1. Although i’ve heard good stuff about Liquid Moly too. In yrs past i’ve owned 8/9 saturns including the one he’s working on. All good cars. DON’T .. don’t put diesel in your car. 🤔

    Engine got roughed up and now harsh sound is heard from engine due to disel engine flush. Repenting now. Should have used other commercial brand. Be careful with engine ultimately its your money. Decide to be safe. Consult car service center, at least one can catch hold of person available for claiming damages.

    Totally wrong method of flushing an engine. Viscosity is much lower and the diesel will wash off the oil layer at the cylinder walls. I prefer ATF oil or hydraulic oil 68 centistokes

    The diesel that you drained out didn't look dirty. Either it didn't work, or the engine wasn't dirty.
