he says "i don't know" alot, i agree.

As a mechanic for over 20 years, I must admit it does work. What ever is not broken down, burns out safely hence the 15 min idle without driving. But ofcourse, we mechanics would highly NOT recommend it if you know what I mean 😉 😉

Big difference between preventative flushes every oil change, and flushing a sludged up motor like you are describing. Good points.

[Birdfeeder]

Been flushing my engines for 22 years without any problems whatsoever. This man doesn’t know what he’s talking about.

[LamborghiniVM]

Completely disagree!! Keep oil clean first and foremost, and occasionally flush will keep the internals looking and operating like brand new. Flushing and old sludged up engine at 300, 000 miles is a different story

[rustyorlando]

The mechanic said I needed an engine replacement because the knocking was really bad. $8 can of flush, the engine lasted eight more years. What he said about doing the maintenance is absolutely true, don't get to the position of needing an engine flush.

Hey Frank, I get why you fear oil flushes but there is really nothing to worry about. Most “oil flushes” are in fact a diesel or kerosene based liquid with a higher percentage of detergents found in modern engine oils. The reason why is because diesel and kerosene are excellent dissolvers of carbon and sludge. That is also the reason why oil flush manufacturers will advice you never to drive the vehicle while an engine flush is in the engine oil. While diesel and kerosene have some lubricating properties, they are very thin and may not lubricate the engine very well while the engine is under load. Because of the low viscosity and excellent dissolving characteristics, you should not be afraid of blocking passages or the oil pump itself. Really, low viscosity oils with strong detergents would pose the same threat then. Which they really don’t. But to clarify why some modern cars, especially modern Japanese and European Diesel cars, really, really need an engine oil flush every service, is because of the very high compression and temperatures combined with very narrow oil passages and the oil pump pre-filter catch, which really tend to carbonize and starve critical parts of engine oil. These Euro6 engines critically need these flushes to stay healthy.

You need to stay as far away from cars as you can. You have no idea what your doing

I was a mechanic in my early tears so this IS A VOICE OF EXPERIENCE when a flush is done you should NOT leave the flushing agent in the motor for more than 10 mins of running on idle THEN drain and refill with correct oil and filter. End of all the shit you think is correct

[denforundrade]

A gave my Saab 9-5 a flush with omega 907 with 300K miles (20K metric miles) and it ran quite perfect before the flush but afterwards it started to run even better. I knew my engine was not having any problems with sludge and was as clean as can be expected for an engine with those miles so the flush just polished everything up a bit and made the engine run smoother.

The oil was black as night and the smell was quite potent....

[harrys.]

When you do an engine flush. Drain half your oil out then put sump plug back in. Top up your motor with kerosene to the full dips tick mark not past it. . You will have half oil and half kerosene. Then let your car GENTLY IDLE FOR ABOUT 5_10 MINUTES... DO NOT REV YOUR ENGINE. After this turn your engine off and drain oil kerosene mix. Replace filter and oil. Job done.

It's called faith, brother. Have a little faith in the product you purchase. After all, companies would never make outrageous claims and lie to you 🙄

[brianandrews]

A diesel fuel engine flush saved me from tearing down the heads to replace the lifters on my BMW M50 engine, because the previous owner(s) didn’t keep the oil change. That all being said, I wouldn’t do it to an engine that wasn’t having a sludge related problem nor would I take on the liability of doing it to a customers car. If the radio broke after the flush, they would blame you and your engine flush!

[freespiritagent]

This guy doesn’t want you to buy “engine flush”. He wants your money of course. Amsoil and LiquiMoly disagrees.

[MrXilef]

of course mechanics don't do motor flushes because there's no money on motor flushes, mechanics do rebuilds and do expensed fix lol.

[righteousredneck]

Doing regular oil changes is key! As well as keeping your coolant clean. So many people are paranoid about keeping carbon and sludge out of a motor. Truth is...you WANT a little carbon at least. Carbon SEALS the rings over time. Getting absolutely all of it out can cause blow by and you can run into trouble.

[logangross]

Uhhhh. The sludge is already in the engine...why would it moving make it worse??? If your engine is nasty and needs a flush why not try it?! If it’s that bad you have nothing to lose.

[ReedyFPV]

For real though, ONLY reason NOT to flush an engine is because the screen in the oil pan can easily clog with the sludge. It is not a chance, it's a certainty. No oil moving through means nothing on your cams and lifters or crank. You will blow a bearing within a few miles. Weakest point that fails from this are your bearings on the crank. Which is as deep in the engine as possible. So, to safely 100% flush an engine. Flush>Drain>Remove Oil Pan>Brake clean oil uptake pipe/or remove and clean pipe>Fill with 10w whatever and change oil and filter in 50miles or so. The oil does not need to do any more than circulate and drain into the pan at least 5-6 times from normal run temp. Drain oil Leave plug out for as long as you can. If you really want to flush and not be paranoid about latent dislodging, clean the pan again. Put on a new gasket, waste more money. Just change at minimum geez.

We do oil flushes on many makes and models as an added measure to make sure the engine is lubricated a little better during some repairs. We recommend it on vehicles that come in severely past the oil change interval (3-10K miles over) and if we see significant buildup when removing some type of engine cover (valve cover, oil pan, timing cover). We recommend the flushes are continued every oil service until the sludge and buildup is no longer present but will typically be removed in 1 flush and is inspected with a borescope to verify. The engines that also suffer from oil passages clogging like the 5.4L Triton engine and GM oil pressure sensor screens benefit from these flushes. The GM's suffer fewer oil pressure sensor failures and the Ford 5.4L have less VVT solenoid and timing gears sticking during operation after these services. Ford's 5.4L oil passages are part of the block and cannot be cleaned manually which is why the flush is used. Although it won't fix the clogging issue completely it has been able to reduce the failures in the VVT system very well and has completely fixed some of these issues on 200K+ mile engines after timing components continued to fail even with factory components installed.
BG's professional grade engine flush has actually been really good at breaking down the sludge and I've never seen visible particulates in the oil after a flush or in the oil filter and don't feel any gritty texture in the oil either so I've been confident it will not cause damage. It's important to know you cannot drive the vehicle or raise the rpms with this flush solution in the oil and has a second conditioner that is added to the engine oil after the flush. It's definitely not needed on engines that have regular maintenance done but we get a ton of mismaintenaced vehicles and it's proven itself to not be a snake oil, although the consumer-grade ones that are bought from the auto parts stores seem to make little to no difference by comparison. They have their place and I think they're useful in some specific applications.

Very true. I had a 2010 Accord 4 cylinder and had 225K miles. It was running good. I was a dumb ass and wanted to see if an engine flush would make my car run smoother...NOPE. It was a bad mistake. I did it and within a few days after doing an engine flush, my engine was damaged and would not drive.

SO DO NOT DO ENGINE FLUSHES!
