In this video I try out Liqui Moly engine flush along with a fresh Molygen oil change and finish that all up with a bottle of that sweet motor honey lifter additive. All products made by Liqui Moly in the motherland of Germany.
Step one: pour one entire bottle of engine flush into crankcase and allow engine to idle for 10 minutes. Seriously, just let it idle, no r3ving!
Step two: perform an oil change. Drain the oil and change the filter.
Step three: fill with new 5W-40 Molygen oil (Approx. 7 quarts capacity for N52) and add the can of sweet German motor honey. I mean Hydraulic Lifter additive by Liqui Moly.
Overall the results were pretty good with the engine flush and hydraulic lifter additive and fresh oil. The lifter noise was greatly reduced at idle, and moderately reduced when accelerating lower RPM range. I think it needs more time to coat the parts and work into the motor 4-500 miles before seeing the maximum effects of the products and new oil.

Next time zeit change the filter while the oil is draining because that flush seeped to the bottom of the crankcase that was mixed with the oil but you put the plug back on at the bottom so you still had flush in your pan.

[@karstgeo7290]

Should really leave the drain plug open while you do the filter to get all of that oil out as well.

[@Jaafar_ali]

Exactly..

Nice production of the video

[@toothferrin]

it sounds better! the noise that you have after the engine flush sounds like normal injector noise. but its hard to tell when your not there in person. good video.

[@BIMMERZEITT]

thanks Matt! Yeah, the flush and change definitely helped. Who knows how old/what kind of oil was in there from the previous owner.

For the lifter additive,it goes with all oil right?

[@jmurockstar]

Interesting... the drain on my 2006 330xi is on the very bottom and is vertical instead of being on the side of the sump. Wondering if it's a 330 vs 328/325 thing or a rwd vs awd thing.

[@randyr.8536]

Wow this Lifter tick additive actually fixed my lifter tick issue on a cold start up ! Within couple of seconds I heard no more ticking and if you guys wondering on the measurement for my N51 is 7qts used in total & used full synthetic 5w30 & grab a Empty bottle of a 1qt and add the additive first and fill up the rest with 5w30 to hit a full quart and a 2nd quart of your final bottle of 5w30 👍

[@binmoy9803]

I thought the green Liqui Moly doesn’t work on older cars, like in FCP, it’ll say that new Liqui Moly green may not work for my 2008 E90, N51. The car in the video looks like N51, you said N52, but around the same period. So can the new green Liqui Moly work for my 2008 E90 N51?

[@silviataylor92]

nice car!

[@technik333]

nice M3 bumper, did you notice any performance improvement at all with the additive?

[@BIMMERZEITT]

thanks Leon, the previous owner had that M3 bumper installed it is a huge aesthetic upgrade! Need one for my 335i. I haven't noticed any performance improvement, other than the engine sounds happier with fresh oils!

[@rowen898]

Change your VANOS solenoids! Get them from BMW - they are expensive but your engine will make peak power! - I noticed a whine on your car that my car makes when the solenoids are worn but not enough to throw a code. The whine will go away and you will get fuel economy at around 7.5L/100km with a heavy foot.

How can you explain to people in such as wrong ways to change the oil? , have you got any ideas how to change?

Dont use flush, it will do more harm than good. just always use good quality oil, and do often oil changes.

The green oil is good to seek oil leak. Not a recommended product for ticking.

Going to do this same thing this weekend. My n52 with “only” 170k miles gets a lot of lifter tick. Never done an engine treatment, so i’m curious to see how it works. Great video

[@brandondarnes3699]

@@AviaryAviles159 Didn’t do the engine flush, but the lifter additive made it noticeably worse. Yep- worse. Changed that oil after 1,000 miles.

Curious why you went with 5W-40...I’m in the Midwest and we get cold weather like the NE does, I’ve always gone with 5W-30 in my M54...maybe there’s something I don’t know?

[@BIMMERZEITT]

Spaced Kowboy it was recommended by the guys at FCP Euro. 0W40 is best for an M54 btw. You can also use 0W40 and 5W30 in the N52!

[@bigjml]

Like many European cars they can use a wide range of viscosities. As an example my W222 S350d can use various specs, such as 0w30, 5w30 and 5w40. The most common oil is 5w30. Though I shall likely be using 5w40 at the next oil change. As long as it meets 229.51 or 229.52 its all good. And in this case the 5w40 meets LL01. Does your handbook have the viscosity/temperature chart ?

[@z4funkdreamer986]

hi what is the oil consumption of your engine at this high mileage what mileage did you start to use engine flush and did you notice improvement about oil consumption ?

[@BIMMERZEITT]

Z4funk Dreamer not sure I only owned the car for 5 months

[@MrCuckoobox]

Both of the e91s that my wife had (she still has one) would start ticking near the time to change the oil 3.5k - 5k..... I was originally changing at 5k, now at 4k........I tribute all the tricking to the lifter sticking from build up. The oil may last 7.5k -10k and still lubricate but the varnish and sludge starts to build and it does not take much to cause issue with some the small channels in these engines.

[@BIMMERZEITT]

Yeah unfortunately this engine is known for lifter issues. I believe there was a recall at one point, but only covered at low mileages. At this point, just have to live with it

[@MrCuckoobox]

@@BIMMERZEITT Add some Marvel Oil.......I know some say it is snake oil but I have used it for years in gas and oil with no issues. Add about 8 oz with the oil change. Quiets the valves.....It ends up evaporating within a week.

[@BIMMERZEITT]

@@MrCuckoobox interesting could try it. My friend had an m3 with valve noise in a rebuilt head, I suggested marvel mystery (my dads tip) and it got rid of the noise right away! Never came back.

Isn’t the “drain plug washed” actually supposed to go on the oil filter housing ???

[@sincerelyjapan]

I know this is an old comment, but no - that's for the drain plug. I could see how it would be confusing considering it comes with the filter. Hope this helps!

[@raybutts9133]

in my opinion: use 5w30 with ll-01 spec, buy an oil filter housing wrench and use a torque wrench to tighten .

[@TheMstwntdLMSV123]

This oil has the LL-01 spec. If he does a lot of spirited driving the 5w40 might be the better choice

[@raybutts9133]

@@TheMstwntdLMSV123 Yes , but just make sure spec is LL-01.

[@bigjml]

Liqui Moly list 5w40 Molygen on their website for this engine. Its LL01. And you don't need a torque wrench on the oil filter housing. They have a stop so you can't over tighten them or under tighten them. Well, maybe if you have the mechanical sympathy of a gorilla....

[@brey93]

I have a 2001 530i with 167k and i bought the top tec 4200 but it says on every site that it isn’t recommended for my car. Should I still use it or go with the regular liqui molly 5w-30?

[@carforumwanker]

add flush . run engine to temp and no problem to drive a few miles .Leave in car over night or for 4-5 hours . then warm up engine again with a few miles. Drain . Use a cheap oil and only put 1/2 the required amount in. cheap filter also .Run car for 5 mins . Drain . Now the engine has been really flushed .Put better oil and filter in etc .

[@cyberairwolf]

wouldn't it be better to just rev your engine at times instead of going out for a run?

[@joeyjones6638]

Hi mate before you open the drain plug ALWAYS open the filter cap so the oil in the filter drains into the oil pan if you dont you will still have half a pint of old oil still in the engine

[@baranguler1168]

I see in the video that you poppet your filter after tightening the drain plug, hope you emptied that old oil with flush. Probably some editing foult.

Hi. Use Lubegard 30902 Bio-Tech oil additive. This really works and reduce noise from mechanics (including lifters) significantly. In my experience, much better than Liqui Mol stuff.

[@BIMMERZEITT]

Not sure, reach out to Liqui Moly with a quick email. Find their Facebook page.

Adish jogatar liqui moly stated that while using Molygen not to use any additives since it already has additives. You can use the engine flush. Now if it was any other liqui moly product then you can add additives. Hope this helps

[@minnus222]

No need to add any additives if you are using molygen oil.

How is your engine holding up after the engine flush? I heard doing an engine flush ruins the engine.

[@BIMMERZEITT]

Sold it to my neighbor almost exactly 1 year ago this month. It had 270,000 miles, he has it up over 280,000 maybe 290,000 no issues.

[@MrRubenRusso]

The only problem can come from the engine having way too much sludge and the engine flush freeing the sludge and it blocking the oil flow. Thats what can kill an engine.

[@kingb7080]

@@MrRubenRusso I ended up doing the engine flush. For over 3wks now no problems. I've been changing my oil every 5k so it's pretty clean in there. But after the flush engine feels super smooth and it's like it gained its power back and drives like new.

Please do a video on how to clean your N52 engine

[@CarbonInstinct0]

Any update?

[@BIMMERZEITT]

Carbon Instinct the oil service definitely helped. I also think the key is not letting it sit for week or two unused, as oil drains from lifters totally and takes a little to build up oil pressure again. Then again it has 269,500 miles so time will tell how long it goes for!

[@BW-kv9wj]

That additive is very thick. It might change the viscosity of your oil. BMWs have very tight tolerances and thickening the viscosity might not be wise.

[@dflex4180]

Liquid molly tests these additives on BMWs they are safe

[@BW-kv9wj]

@@dflex4180 OK. I contacted Liqui Moly and they said it’s not recommended to mix any additives with their Molygen Oil.

@@shanerasberry510 Oil companies are smart. They already know what additive packages to put in their oils. You don’t need to put in additives and screw with viscosities. Especially with a BMW. You’re just asking for trouble.

[@000darkorbit000]

You missed an important step, 1st you did right, but you want to let the oil drain out completely, after that, you open the oil fill cap and unscrew the oil filter, you will notice that a lot more oil will start flowing out of the car... it’s because of the pressure release.

[@000darkorbit000]

Follow up: you always want to put a little bit of oil on the O-rings, for the Perfect seal

[@timkrusemark6123]

In order to get some quantitative results I think you'd isolate the lifter noise. Maybe an automotive stethoscope? I didn't hear an improvement. That, and you could have done the oil change without the additive, wait 500 miles, check lifter noise (with stethoscope) then add lifter product, wait 500 miles measure noise again. Without at least the 500 mile update, this video is kinda pointless.

[@BIMMERZEITT]

Tim Krusemark yeah, it would take a lot of effort to make these kinds of videos very scientific. It did make an improvement in sound, but since it was all done together (time is limited these days) it’s impossible to isolate each. I believe the biggest cause of lifter noise is old oil and letting the car sit for long periods to where the oil fully drains due to gravity and the lifters now longer have full oil pressure. Of course there is the wear issue too, especially at 270,000 miles.

[@jonathanpetowsky1928]

This oil change gave me anxiety, you forgot to open the filter housing while draining, and didn't lube any of the gaskets with clean oil. Great video otherwise though filming and Quality is A1

[@bigjml]

The small amount of oil left in the filter housing will make zero difference, to get it all out you would need to suction it out anyway, they never drain fully. And those are O Rings not gaskets. And just because you didn't see him do it doesn't mean he did it. He probably didn't realise that KZbin is full of pedants that think an O Ring is a Gasket...

@@BIMMERZEITT It’s 100% synthetic. Liqui Moly is not. There’s a reason why every oil company (except Motul & Amsoil) write Fully Synthetic or All Synthetic in their bottles. They are not allowed by law to write 100% Synthetic on their bottles because they have mineral petroleum in it. These companies get away with writing Fully Synthetic because the law allows that if there’s a certain percentage of synthetic base stock and/or the oil itself, they can call it Fully Synthetic. Basically they are deceiving the customer to thinks it’s 100%. Liqui Moly is not 100% synthetic. Look at Motul’s bottle. It says 100%.

@@BW-kv9wj thanks for explaining... that is interesting 🧐 I’m definitely going to look into this now haha

[@BW-kv9wj]

@@BIMMERZEITT These oil companies get away with saying Fully Synthetic because the majority of the oil is man made (synthetic) and the remaining oil is from the ground (petroleum). So because the majority is synthetic they are allowed to call it Fully.

@@BIMMERZEITT I don’t know what the percentages have to be, ie; 90% synthetic, 10% petroleum in order for the companies to be allowed to say Fully Synthetic. But with Semi Synthetics, they have to drop the synthetic percentage and raise the petroleum percentage to call it Semi Synthetic. Just remember one thing, there’s only 2 companies in the world that I know of that are pure 100% man made oil and ZERO petroleum distillates from the ground. And they are Amsoil and Motul.
