The Best Way To Flush Your Engine - Why & When To Use Engine Flush

The important steps after chemically flushing the engine oil is to change the oil and filter again, Flush again, run the engine for 10 minutes and then drain & replace oil & filter. This second flush oil change is to help reduce the deposits that are circulating after initial flush. The last step and most important is to drive 1000-2000km max before doing another oil & filter change. This will give the engine the best chance to keep cleaning and removing those sludge/deposits

I didn’t think there was anything wrong with first clip. Then after 2nd clip (1st engine flush) I realized this was a gas motor not a diesel. Incredible

[@ColonelEMHouse]

Me too. Exactly.

Note to self: If oil filter is full of chunks of engine metal, remember to run the next engine WITH oil.

[@julianpiper240]

I had a 2AZ-FE exactly like that. Absolutely caked in crud. Oil pressure warning flickering on. The oil pickup was plugged solid. I had to flush the engine, change the oil, wash out the rocker cover 3 times, and even that wasn’t enough. I had to fill the thing with diesel and let it soak. After a couple days, I drained it out, oiled the camshafts up and refilled the engine. All good now!

[@vamoneygroup]

This is what I'm gonna do. I got a 03 Suburban 5.3L. It's caked in sludge. I got the heads of because I thought I blew the gasket. Nope just sludge fighting threw the gaskets and into the exhaust. I'm gonna fill it I with 5 gallons of diesel and let it sit.

Did a flush to my Suzuki 1.4 boosterjet a few weeks ago. It has only 83000km so it should be pretty clean. After the flush I changed oil and filter, run it for 15 minutes. So all the deposits and cleaning agent would get in the new filter. After that, changed the oil for premium oil and again the filter as well. Runs great.

[@andrewb8548]

Get a case of cheapo filters and couple of gallons of k1 kerosene. Put a gallon in the crank case. Start it. Don't drive it. 1 minute, change the filter. Do this 2-3 times. Change oil, filter drive around for 20 min. Sludged up Audis love it.

[@user-zl4kj1vz7f]

If that engines had been flushed every oil change from 5k miles onward at every 3k then it wouldn't have sounded like a sewing machine as there wouldn't have been any sludge build up in ANY part of the engine -especially the head. I bought a volvo 850 in 2007 with only 20k on the clock. I changed the oil filter/oil and flushed it at every 3k and used top quality fully synthetic 10w30 oil and recommended Volvo filter. When i sold it in 2020 with 100k on the clock and service book oil changes to prove ALL oil changesTthe man who bought it phoned me 9 months later and told me that he had followed my oil change procedures and the engine was still running beautifully . I would recommend that an engine flush be carried out at EVERY oil change - your engine will benefit greatly from it and you will be VERY glad that you did.

[@anonymike8280]

You were overdoing it, If the engine had always had its scheduled oil changes, you did not need to do any flushes or use any special products. No harm done, of course. But high end products cost more and you get no benefit from them. I have an old Camry with a 5SFE (timing belt) engine. The previous owner had all the oil changes done as recommended and I change the oil every 2800 miles using whatever products are the cheapest. At 173K miles, the engine runs like new. No one makes bad motor oil. All products have their uses, but sometimes retailers stock inappropriate products, for example, non-detergent SA oil.

[@krazed0451]

For an engine this dirty I'd be dropping the sump after every flush to check the pickup condition, quite often crud gets sucked in and clogs it. You should also be hoping none of the oil galleries or sprayers become clogged with what you dislodge. Nice result here, how did it fair in the long run?

Wow amazing do u have pic of top end of engine after second flush

[@thomas316]

First, I enjoyed your video and thought it was very informative. If I might suggest one thing that may improve the clients engine further, if you've not done so already, is to use a "100% PAO Esther" based oil. Esther oils have a much greater degree of solvency than "full synthetic" oil so dissolve carbon build up more readily. The downside is that the oil itself is typically twice the price so I would only use it in these fringe applications. Keep up the good work!

[@zepp3lin]

Penrite EO does come with Esther base as 1 of its ingredients.

[@kupas2]

cooking oil do the same, or just use adnoc px green or kixx bio1

[@nordicpride9708]

I think you are trying to reference “Ester”. Unless you folks spell it differently over the pond. PAO Esters are great, however only in extreme cold and extended drains. Modern group III and group III+ practically match the performance of PAO. This has been proven. Also worth noting, PAO’s don’t have the best polarity (affinity for metal). Granted additives in the oil help this, but PAO is far from magic. Oils have come along way from this 80’s approach to oil formulation. GTL (gas to liquid) is the future for base oil formulation. Cheers 🍻

[@kupas2]

@@nordicpride9708 group III+ have the same poor solvency as PAO too, both are less polar. So oil manufacturer either use ester or group 1 oil to improve solvence. Which is why "high mileage" oil exists. We can use cooking oil instead. corn, canola or palm oil. Unfortunately modern oil lack shear stability of PAO. this is worse in high rpm engine. Worse when oil manufacturer decided that more viscosity index is better. more and more people start to suggest useless engine flush "treatment". When the correct solution should be using group 1 oils or oil with ester or oil mixed with 10% cooking oil (more can result it sludge released too fast and cloging oil passage) So full synthetic today have much worse capability than full synthetic 20-30 years ago.

[@nordicpride9708]

@@kupas2 Group III oils provide almost identical performance to that of PAO with very few exceptions as I’ve listed. Not sure where you get your information, but it’s not all correct. If you are saying modern oil is a downgrade to 80’s blending technology I think you need to speak to some tribologists and see what their reaction is to your statement… Engine oils aren’t intended to remove sludge, carbon and the like. They’ve never been good at this. Their job is to lubricate, cool, actuate solenoids and keep an engine clean. Not resurrect it after it’s been neglected. PAO is in Mobil 1 0w-40 and it’s a ok cleaner. It’s not going to hold a candle to carbon that’s already formed in piston rings, oil passages and the like.

[@charlesnorris2993]

keep in mind, can aslo use a good ATF for the flush additive, as in, 1 quart to replace a quart of oil in a full oil change, the higher detergents in ATF can help clean up sludge ect as well, and it shouldnt hurt any seals. but always change your filter after.

[@rolandleusden]

It's all down to neglect and lack of maintenance. I change the oil and filter every 10K km, use premium oil. Every 20K km I use engine flush. Another oil often forgotten is the gearbox oil, in my case it gets changed every 40K km, manufacturers recommendation. My car is 18 years now and has 200.000 km done. No major repairs, only maintenance and parts that wear.

[@jml9550]

Exactly. Just bought my wife a new Lexus hybrid SUV a few months ago. Had its oils change at 1k miles, then every 5k miles after that from now on. Lexus recommends oil change every 10k miles, which is nonsense. We have 2 other Lexus in the household and the engines still sounds smooth at 158k and 42k miles.

[@jesseharriott4253]

I just dump some diesel and atf in. Drive to town and back and do it again x3. But you have to keep in mind that anything that ended up in the filter went through your oil pump.

[@anonymike8280]

Notice that the sludge is deposited on the inert parts of the rocker area. Engine flushes can be dangerous, Even in a case like this, if the the oil pressure is normal, there is no need to flush the engine. If the oil pressure is not normal, the first thing to do is pull the oil pan and see if the pickup is clogged. If it is clogged ,clean it and put it all back together. You still don't need a flush. Use synthetic oil or semisyntheteic oil if permitted and then accelerate the oil change interval. Whatever wear has been put on the engine component already, you cannot reverse it with any additive.

Would this be a thing to do on like a 1977 v8 ? Engine seems to run good but oil pressure dropes off a lot after it worms up

[@bros1083]

Use something like Liqui-Moly Ceramatec or MOS2, you want an additive on such an old engine whatever you dislodge is getting stuck elsewhere and running an engine in that condition can be catastrophic. The additives mention lubricates and the Ceramatec supposedly fills in holes or scrapes with the ceramic compound to reduce oil burning for 30,000 miles but don't flush your engine.

[@bros1083]

Liqui-Moly pro-line engine flush smells straight like diesel and you mix it with old oil, let the engine run for 10-15 minutes but some shops even go to 30-40 minutes, and you drain it out. You then do half the amount of oil with some cheap off-brand oil let the engine run for 5-10 minutes, drain that out, and finally you put in a new filter + new oil. Mileage, oil burning, noise, cold starts everything became quieter and on a 2012 Camry hybrid the engine was requiring less time to start up and be ready for EV mode. Afterwards I didn't see Liqui-moly MOS2 or any kind of additive besides Fully synthetic oil which already has a ton of detergents and cleaning agents. This was after 150-160k miles, and oil changes every 5,000 miles or at most 6,500 miles.

[@raymondhellberg3600]

Is it just me, or is the engine running with higher RPMs in the "After" recording than "Before"? That could explain it running quieter also... However, engine flushes can save engines for sure. I myself prefer Auto-RX, which is not a flush, but softens and loosens sludge slowly as you drive as usual instead of breaking off chunks and flakes. Slower for sure, but safer imo.

[@MattExzy]

Probably just higher RPM from a cold start perhaps. I somehow think though that level of tappety-tap in the 'before' would probably carry on through the whole rev range, low or high.

[@GrandPrix46]

I go even 1 step safer and just change the oil once a month for a year to clean it. The fresh oil cleans everything up over time pretty well on its own.

Any reason why people prime the filter and rev the engine while using engine flush.

[@gonzalotapia1250]

Just follow the instructions on your flush can. Liqui Moly says that you need to idle your engine for 10 minutes, then change oil. Also, you do NOT need engine flushes on new engines. Make sure you change your oil every 6000 miles (10.000 km) or 6 months, the one that gets firsts, and you're good to go. If you want to make your engine wear less, you can add Ceratec on every other oil change. When you buy an used car, you need to replace and flush every fluid ASAP (except transmission fluid, which needs to be checked with a professional mechanic).

[@CrimeVid]

⁠@@gonzalotapia1250 I take issue with not needing to flush a new engine. I say you should flush and change everything at 200 miles. then put in the best engine oil you can buy. And change oil and filters before you hit 5,000 miles every time. The first one is to make sure all manufacturing debris is completely removed.

Why not using the completely brutal method? - cleaning the camshafts with break cleaner - draining the oil and changing the filter - using high quality or synthetic Diesel instead of oil - idle for some minutes and repeating to change for new Diesel - finally open the valve cover and removing the oil pan; cleaning - new high quality oil with high HTHS and high content of cleaning agents and a new filter

[@covecarpentry]

never seen anything like it

[@sbond1963]

The start up clatter is not related to the lifters or valve train thankfully. It’s coming from the VVT actuator. When the engine is turned off the VVT actuator turns the camshafts into the retard position and locks with a tiny pin. When the engine is turned on, oil pressure unlocks the pin so the camshaft can advance as the engine warms up. The oil pressure is created through tiny veins in the actuator, which I suspect are plugged possibly by sludge breaking loose. It does let go but hammers for a couple seconds so there is still some crud in the actuator or the actuator pin is worn. You can clean that actuator if you choose to. That will get rid of the rest of the noise. It sounds good other than that. Actuator lock pin startup noise is pretty normal for Toyota VVT. I would just leave it.
