Thx for mentioning that flush is rough on seals & gaskets. Not everyone knows that.

I used to flush with diesel but I did it different; I would drain old oil and add straight diesel then start the engine and let it idle for one minute. I would then wait for twenty minutes with engine off to let the diesel get into any sludge etc. I would then restart the engine and let it idle for another minute then shut engine off again and wait another twenty minutes. I would then restart for one minute, shut engine down and drain the diesel then add new oil and filter. Waiting the two twenty minute periods allowed for the sludge to breakdown and come out/off. I found this system worked well with no noticable problems.

I flushed my turbo twin airplane with diesel fuel then I loaned it to my ex-wife and her pilot husband to visit his mother in Florida. It made it to Arkansas before the engine seized at 12,000 ft. Good Job and thanks for the tip. and I don’t care if you do call it Diesel gasoline.

Thank goodness, I'm glad I tried doing it first and yet read all the comments. My engine run's so smooth and saves my gas alot.thanks you

If he’s calling it diesel gasoline that should tell you something

I've been flushing engines with diesel for over 50 years, always good & never ruined anything. The old red ATF worked well and so does Marvel Mystery oil. Too many people who complain about the results were trying to resurrect a shot engine looking for some magic, then blame the diesel or whatever solvent they tried in desperation.

I asked if that is good for motorcycle also please answer

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.

4:12 yea but how much pressure was it making huh? Healthy engine can survive this kind of flush, but some may not, especially those without brass cam bushings.

Love the way he drains the oil with no gloves,then puts gloves on to tighten drain plug

Can’t say I’ve done this in petrol cars, but my diesel Passat wagon and ducato motorhome have had a diesel only flush done every 3rd service. Passat only has 110,000km on it (66,000 miles roughly) but the motorhome over 280,000km. I only run the engine for a minute or so, not 5, then drain overnight and new oil and filter next day. These used to be dirty diesel engines but now take several thousand km’s before the oil turns black, where it used to happen instantly. Not sure on petrol engines as they seem to run clean, but for diesel engines my father taught me this trick to prolong engine life and it’s worked for him, and seems to be treating me well

I was going to do it on my 2004 Scion xB with 302K miles until I heard about the diesel being hard on seals and gaskets. Thanks anyway, good video.

I used to do the similar method, where i used to drain the old engine oil, fill the engine with Diesel and then half crank the engine not letting it start for maybe a second or half and then used to drain it and blow the high pressure air from input and have it remaining diesel and vapors comes out from drain plug and then pour the new engine oil and change oil filter. Never faced any issues, engine used to run light.

I bought a used Porsche with about 55,000 miles on it and took it to an oil change shop that offered a heated solvent oil flush that filtered the solvent through a large pleated white filter that was connected where the oil filter was. I was able to watch the solvent go from its original clear color to a brown color as it dissolved away sludge and deposits from the engine. After that I had a fresh oil filter and some cheap conventional oil of the proper viscosity put in that I ran for about a day. After that I changed the filter again and then put in high quality full synthetic(Redline) oil. The engine ran like a champ for over 150,000 more miles, using very little oil between oil changes.

My '04 Ford Escape developed a loud, very noticeable ticking sound after it warmed up. One needs to understand the inner components working in an emgine. In my case, as well as many other vehicle brands, lifters are designed to operate in an independent manner between valve openings. There's a small port opening on the side that gets covered up upon required use of the lifter to open the valve. If that port becomes plugged from sludge (failure to change oil and filter at regulate intervals, or sediment contamination from outside source), the lifter can be stuck full of oil (solid lifter) or won't let any oil in at all, creating what's called, a flat lifter. There are many products on the market that help clean and flush the engine internally. All contain the same desired chemicals. Solvents and or detergents. Whatever the differences of these product solvents and detergents are is irrelevant. Their performance is what matters. Marvel Mystery Oil is a great engine cleaner. Use exactly as directed. In the case of my Ford Escape, my mechanic (Very trustworthy, capable and reasonable guy) told me to add a quart of transmission fluid to the engine, on top of the oil already In the engine. Start and run (at IDLE ONLY) for 30 minites. Drain the oil and remove the filter. Put new oil in and new filter. Drive for 100 miles. Change oil again. Within 5 minutes of the engine warming up, the lifter noise disappeared. Transmission fluid has excellent lubrication and detergent properties. I have not had a problem since. Using diesel fuel in the manner and quantities described in this video is safe. As with the transmission fluid technique, run the engine at IDLE ONLY. Don't rev it up. Don't drive it. Otherwise, everything the method he used is perfectly acceptable. The best method overall is to use high quality oil, high quality filters and change them often. Brand new cars under warranty should be changed regularly by the dealership. After warranty, continue to change oil regularly and flush at least once a year or so. With whatever technique you feel comfortable with.

SIR CAN YOU TELL ME PLEASE, HOW MUCH AMOUNT OF DIESEL AND FRESH OIL SHOULD I USE DURING FLUSHING. PLEASE TELL ME THE EXACT QUANTITY

I didn't see any sludge coming out? I thought that fresh oil was gonna get all dark with all of the sludge but it came out clean, something is wrong

I did a diesel flush on a Subaru 2.2 with a ticking lifter. Worked like magic (yes 2.2 had hydraulic lifters )

I recently got a van, and the guy swapped the engine into it. I'm assuming it was from a pick your part yard because there's slight rust inside it when i changed the spark plugs. Would an engine flush help rust inside the crankcase?

I did this to my 64 Ford Galaxie 351 Windsor motor which used to smoke like hell, I drained the oil, put in 5 quarts diesel fuel, let it run until the engine temperature got hot, drained it, put in new oil and filter, drove it for a couple of days, then changed the oil and filter again and car never smoked after that and it ran great for 1000's of miles after. I kept the car for 3 more yrs after doing that, I'm not sure if I would do that to some of these newer engines today but it did the trick in the old engine???

Thank you for providing a video on how to flush your engine without damaging it further. I just did this on all of my cars and I will recommend this method to all of my friends! I also used kerosene to flush my cooling system and that also works.

It's okay folks. It was only a Saturn. How much more damage could it cause?

2 or 3 quartz of oil. Which one?

On time scheduled oil changes with usage of synthetic motor oil and synthetic oil filter, while using the correct motor oil type and amounts, also might have to top up every now and then between oil changes, will keep the engine clean and well lubricated, which will keep it running well for long long time without issues or very little issues if any.

Most of this is common "Old School" tech, and hardly needed today. In the 60's, detergent oils had come of age, but nothing close to what we have today. Engine flushes were the norm for engine longevity. My grandfather maintained all his fleet of logging trucks, heavy equipment and personal vehicles by flushing regularly. And yes... he did this with straight diesel fuel. As others have commented, he let an already warm motor idle (and ONLY idle) for about 5 minutes, then drain, replace the filter and refill with fresh oil. I could see this still being used if you bought an older engine of unknown condition and wanted a maximum flush, but most oils today do pretty good at cleaning on their own, and synthetic more so.

I use also mixed diesel fuel and engine oil to flush my 91 corolla. Been doing it for five years now so far the oil seal and gasket ar still good. I di this procedure once a year

Just love that Saturn doing all that fancy work to it

Alot of comments say do your oil changes at 3,000 miles, if you do that from the beginning you wont have sludge. Well lets say you got a vehicle that was neglected, or say you dont know the history of it. And the vehicle burns more oil than usual. The vehicle has high miles & has sludge. What's the "safest" method of flushing? Diesel? Transmission fluid? Liquid Moly engine flush? Which flush would be least likely to affect seals? Its a 2010 Chevy Traverse. 3.6L.

I run my car on LPG. It is incredible how clean it burns. The engine is bright shiny clean inside, like when it was new.

Best bet to add 1/2 a qt or a full qt of marvel mystery oil or transmission fluid to the oil about a few days, up to a week worth or 100 to 500 miles of running the engine before you change it then just change it like normal. Can do this every oil change and it will keep your engine squeaky clean on the inside. I change oil and filter every 5000 to 7000 miles and have been doing this for many years. I've got a little over 400,000 on my Dakota with original engine and no rebuilds, and it doesn't use a drop of oil between changes and it still runs good. I've used different kinds of engine flush in the the past, including diesel, and found that MMO or transmission fluid, either one works best.

I used 1qt diesel mixed in oil on my rav4 lemon buy but it helped. Ended up needing a lot more cleeaning than that but still running good over a year later.

Make sure there is enough anti-wear in the flush. Mixing first will help. Adding Zinc (ZDDP), will help. Be more careful with solid lifter valve-train and extra stiff valve springs!

After flushing the diesel/oil mix, you MUST then add the minimum amount of oil to safely run the engine and let it idle for about 5 minutes. Then drain that oil. This will assure that ALL of the diesel fuel has been drained. If you don't do this extra step you will have too much diesel remaining in the crank case and throughout the engine. Then when you add the final new oil the viscosity rating of that oil will be changed in a very negative way and during the next few thousand miles you will be slowly damaging and wearing the bearings out in the engine from that lower viscosity. You will not have the proper protection if its diluted with that left-behind diesel fuel from the first flush.

I've flushed out multiple high hp engines with diesel fuel with great results. The diesel will break down the sludge,not clog oil passages as most commenters are suggesting. Remember,the diesel fuel shouldn't be in the engine for more than a couple minutes. Drain and then flush with fresh oil 2-3 times.

Will diesel harm gaskets in motor?

Scotty Kilmer will love this

I use a similar procedure to bring back to service a marine engine that had beed flooded, I use WD40 instead of diesel fuel. Without turning over the engine, I flush the crankcase and I fill with half and half mixture of oil and WD40, I start the engine and let it run idle up to normal operating temperature, I repeat the procedure with a mixture of 1/4 WD 40 then I change the oil filter and reinstall normal oil. that has well served me up to date

Marvel Mystery Oil and Diesel together might be an ultimate combination. I usually put one quart MMO in at every other oil change. It keeps the internals clean and working perfectly without ever having to flush the engine. It’s done well for 30 years of me doing this.

What happens to diesel that’s left in the camshaft housing.

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.

I fully agree with your flushing video using diesel fuel. Years ago I was driving a Pontiac Grand Prix with a 400 cubic inch engine. I was cash poor and only changed the oil occasionally, never before 10,000 miles But every other year I flushed the motor with 4 quarts of Diesel and 1 quart of fresh Pennzoil I then added 5 quarts of straight 30 weight Pennzoil. I drove the car 465,00 miles without any kind of engine failure.and never had the heads off. To this day I still use Pennzoil, but now with my PTGT ( turbo) I use 5 30 weight oil ( factory recommended viscosity ) It is a 2003 model with 184,00 trouble free miles.Thanks for sharing...Mr. Randolph.

Sea foam can be used as a flush. Directions are on the can... it will not damage seals.

I put in 10% ATF with my fresh oil. '97 Chevy with 246K. Also mix diesel in the gas tank. 1 pint diesel to 7 gallons gas. That's 1 ounce diesel to 56 ounces gas.

Would using 0-30 weight and diesel do a better job ??? Thanks VF

Engine Restore is safe if you closely follow the directions. Frees up sticky valves and piston rings.

THE ONLY THING YOU NEED TO DO TO EXTEND ENGINE LIFE IS TO DO VERY REGULAR OIL AND FILTER CHANGES. NOTHING ELSE.

The engine oil also have detergent agent that can clean up all carbon deposits in the engine.just change the engine oil frequently follow the range of mileage.

Good practice for a dirty motor. Cheaper and better than motor flush which is too weak due to liability purposes. After doing this, on refill of oil substitute 8oz of Seafoam or 32 ounces Marvel Mystery Oil (or any transmission fluid) will further clean the motor between 4,000 oil changes. Some oil screens are accessible thru the drain hole with a toothbrush. Not a bad idea to scrub it and then fill pan with additional clean diesel thru the dipstick hole and mildly flush out the bottom of the pan and screen. Some of these remarks. They clueless.

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.

I actually saw someone flush a Isuzu engine using straight diesel fuel . All I can say is it worked for my friends dad . He drove the little truck everyday for a few more years .

Add in 1 or 2 liters of Dexron or Mercon ATF, to the crankcase, then run it and drain it. Cleans well, and without harming the gaskets and seals.

If the treatment *fucks up the seals-* what's the point?

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

There is a product called WYNN'S ENGINE TUNE-UP. Put it in your oil follow the instructions. A 5$ product developed by a reputable company. You could also used seafoam, MMO, among others. Only use stuff that is compatible with motor oil and does not destroy it. If you can't drive with the stuff in the crank case don't put it in.

Isnt there any problem to the oil pump during cleaning operation and how long you kept engine running ? Thanks allot

I have a 14 ford edge that i chsnged oil every 3000 miles now at 199,000 developed low oil pressure I used to auto medic flushs and still no results i did see it had diesel abd kerosene in it...it cant be the oil pump gotta be a blocked port or something i only have 9 psi at idle but as soon as a tap the gas it goes away

Sure, I’ll listen to a guy who thinks “diesel gasoline” is a thing.

in the 70 and 80,s we just used to buy a cheap oil and run the car on that for 100 miles then change it for premium oil. And that cheap oil is good to use again for flushing at a later date.

I decided to change the oil on our work truck, its a hilux ln107. 2 years ago i changed the oil only cause they told me to leave the filter. Today i drained the oil and came out like sludge and so i removed the filter also. Should i add new oil and let it drain or diesel?

Hi, is it possibile do this also on euro 6 diesel engines with particulate filter?

Many moons ago when men were men and goats were nervous, I did this on an Onan 2 cylinder air cooled engine. The result was that it needed a rebuild thereafter. I'd sooner do an extra oil change in between the scheduled oil changes and flush the engine that way, much safer and kinder to the engine

Iv used this method for 20 years, , with high mileage cars and low mileage, leaving the diesel in the motor up to a week for a full thorough clean, results are amazing. , motor wise, very quiet and more responsive, , ........

ok, my question..is it safe for the oil seal or rubber seal in the engine?

Hi brother I'm from Tamil Nadu State India My Nissan evalia 1.5 litter diesel van Engine flush Use only diesel or mixing engine oil please tell me

I did this on a 4 wheeler that went a lot too deep. I filled the crank case completely and drained it a couple times before I brought it to proper level and actually ran the engine. I also flushed the diesel out with oil until it smelled normal.

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 .

Most diesel sold at the pump today contains a certain low percentage of biodiesel. The biodiesel improves fuel lubricity that is lacking when sulfur compounds are removed during refining to meet clean air standards. The biodiesel, essentially methyl esters, is a powerful but non volatile solvent that breaks up grease and sludge very well. Too well, in some cases, ask in when large diesel ferryboat fleets switched to high biodiesel blends and then experienced rapid clogging of fuel strainers and filters, leading to engine shutdown from fuel starvation.

I flushed my old vw golf with new oil and just 0.5 liter of diesel. Ran it att fast idle for 15 min and the oil was really dirty afterwards so I guess it worked. The loud valve ticking also disappeared.

Have used diesel fuel to clean engines for many years including lawnmowers etc ... it works wonders .. also my uncles used transmission fluid aswell.. sort of like using vegetable oil in my 2004 VW diesel tank i gained horsepower and the inject pump was near silent.

I like how he drops crankcase plug in with the diesel. Maybe he's trying to clean that too lol

I see alot of negative comments about flushing an engine with diesel fuel and I can guarantee you this works. If you have a neglected engine with sludge or your oil had water or coolant enter the oiling system, this is the way to go. I've been doing this for years on marine engines.

What ever you say guys, But his Saturn is in Great condition!!!

I'm quite secure that if u remove the oil pan there is still a lot of dirt

I flushed my crankcase with diesel this week and the amount of grit that flushed out was incredible. Will be looking for oil leaks but I don't think the diesel was in there long enough to cause any problems.

Does diesel fuel oil flushing works on gas engines or no?

Thanks...I am going to try diesel in my lantern

Scotty Kilmer would not approve this.

true enough, in Asia we normally call diesel fuel

After draining the diesel and oil mixture, I would have added another couple of litres of fresh oil to flush out any diesel fuel remaining in the base of the sump just to be safe

Is there any problem if we use these procedure in a 125cc scooter?🤗

Good method if you're trying to clean a really dirty engine. If it's not so dirty I'd recommend flushing the engine with regular oil, meaning just change it more frequently

I really want to say bad stuff. I'm leaving now.

how does the motor feel now?

Which Saturn is this? Looks fancy

lets all pause for a moment at :06 and admire that Diesel price of $ 2.85 .... RIP

Fastest way I know of to plug up the oil passages to main and rod bearings when all the sludge breaks loose.

Just use Marvel Mystery Oil. It's cheap and it works. Diesel like you said can damage seals. MMO won't but basically does the same thing. The last thing you want to do is harm the rear main.

What? Diesel gasoline? Do you keep it next to your semi-fully automatic rifle?

Use Amsoil engine flush then use a cheap synthetic for the next 3000 miles. It'll be plenty dirty after cleaning the engine. Then use a premium synthetic like Amsoil and watch leaks go away and oil use stop over the next 5000 miles. Same thing with the transmission using flush and Amsoil synthetic fluid. BTW, there's nothing like synthetic for saving wear and rejuvenating seals. Use Amsoil or the best filter you can find. Never had an engine that didn't use less or no oil doing this. Notice how synthetic lubricants have been on the rise as the only manufacturer lube since the early 90s? There's a good reason for that and superior lubrication is the reason. A low mileage vehicle changed to synthetic lubricants will last much longer. And these days it's mandatory in most new equipment.

Nice Saturn!

hi bro...i want to ask...can i add engine flush into fuel(petrol/diesel) tank and run it normally?

Thanks for sharing a lot of people don't know this science help them with knowledge bro.

Diesel gasoline.? Is this a new brew ? Or have you confused yourself with names ?

The best flash eng ... BG EPR

Does it work same with petrol engine ?

There is no such product as "Diesel Gasoline". There is Diesel Fuel however. They are not to be mixed together.

What I do during oil changes is that after the oil stops dripping, I will pour 1/2 quart of fresh oil to push any remaining old oil in the pan and it works.

Work great on swamped quads as well. Saves about 15 oil changes fyi

How much diessel you put in?

Just use 100% synthetic motor oil,it is highly detergent and will keep inside of engine clean.
