The PROPER Way For An Engine Flush

[@mcdoob]

I emailed Liqui Moly and asked them if you need to do a second oil change after the flush and they said you don’t need to. They basically said that the engine flush is just highly concentrated version of the additives that are in their normal oil and that by draining the oil with the flush in it, you remove enough of it that you don’t need to change it twice. It will just mix with your new oil. These companies have already considered these things. So in case anyone is wondering- this is a waste of time and money

Saved me bro I was debating on buying some cheap oil for it but there’s never truly “cheap” oil for a Mercedes! Thanks!

Yes especially for engines under 100,000 miles just do it once let it idle for 15 mins warm then flush and fill with LiquiMoly Oil the residue of the flush will not harm the engine.

I do agree with you. I too don’t want to waste more money/time. However I have seen two videos that do these kind of extra oil/filter second flushing and it is true that the second oil have those black oil residue. So I am still debating whether it really necessary to do the second flushing or not.

I would only ever recommend ever doing this if you have an older, high mileage vehicle and you're unsure or know oil changes haven't been done on time and it has issues like oil burning or other performance issues. If oil changes are done on time using a good quality oil, you should never need to do this because the detergents in the oil are good enough to keep the engine clean over the long haul which prevents sludge buildup.

Correct. Used vehicle so that's why I did it. Never didn't it since because I am on top of my oil changes

[@BW-kv9wj]

To be thorough, drain oil, put in cheap oil with flush. Drain and put cheap oil in again and a second can of flush. Drain, put in cheap oil again. Drain that out and put in Amsoil 5/30 Signature Series. So you will need 3 rounds of cheap oil and 3 filters and then the last round of the good stuff with a good filter.

[@n55morris14]

I've seen someone one the forums do 3 rinse. Probably the absolute max effort. I wouldn't think this car is in the worst condition so I did just the one. And unfortunately amsoil isn't readily available on the shelves 😞

[@charlessailer4580]

The directions don't even call for one intermediate flush, let alone two or three. Help me out here.

[@gotdirt17]

If you know the previous owner and are certain the vehicle received regular oil changes then a flush could be a good thing to do. However, it's not recommended to flush if you don't know the oil change maintenance schedule it received. Lets say the vehicle engine is full of sludge, then cleaning it out as good as you can may seem right. But think of where that sludge goes. What you see draining into the waste tray is only part of it. Anything internal ((filters/screens) are now possibly clogged with sludge.

I've seen online that, it's not good to do full engine flush with a car you have no history of oil change maintenance because filters in the engine might clogged up. They say, you wanna do it slowly with frequent oil change intervals. Maybe a little additive like gumout or seafoam before oil change would help it.

[@notsureyou]

Correct, and some mechanics won't do an oil flush unless they first take the sump off to ensure that it isn't full of crap.

Agree, Never judge the quality of oil on the color. You can do 10 oil changes and the oil will go darker after driving.

[@toxmaster1]

You should try test with paper and dirty oil after second oil, it will be the same.

[@SedatedByLife]

Your oil always gets darker the longer you drive it between oil changes. The oil that came out was barely used. Maybe halfway though its service life.. There were no clumps or bits of carbon that showed on your examples which shows the engine was in very good working order. The GDI engines are no stranger to getting buildup in the intake but as long as the seals and rings are good, the oil will only discolor from the heat it contends with. My 2002 pickups oil looks the same as your demonstration at every service interval. It's about changing oil regularly and on time if not a bit early. Ultimately, that is what will prevent premature wear and other issues in the long run

[@vanja7589]

The Liqui Moly Oil would look like the cheaper Oil if you would drain it again. It would have a much better effect "Engine Cleaner + old Oil, then cheap Oil + Engine Cleaner and then the Oil you want to drive with ? Or am i wrong ?

R u saying to flush it twice with liqui moly

[@notsureyou]

What I recently had done, on my very regularly serviced car...... that I have owned since new, Oil flush added to the "old" oil since it was still in good condition (not dark brown etc) and so still able to hold any contaminates in suspension. After running it for the correct amount of time, drained the oil and changed the filter. Added a cheaper oil to clear out any of the remaining flush detergents, ran car for enough time for that oil to get hot etc. Drained that oil and changed the filter, followed by adding the good stuff (more expensive oil). Although my car is very very well maintained, and theoretically didn't need a flush, I decided to do it because that particular engine has low tension piston rings, and if they gum up they become jammed off centre, Leading to the bore becoming damaged, and the rings not sealing followed by developing an oil consumption issue. So whilst OTT, my choice was not without reason :-)

If you change your oil at the proper interval and use a high quality detergent oil you should never have to do this. I use mobile 1 full synthetic and torn motors apart at 140k+ miles with no sludge or deposits.

[@erasmusvenport8830]

I'd have reused the old sump plug for the first cheap oil flush and only used the new sump plug for the new oil since the washer that comes with it is a crush washer, also when the moli is in the engine don't just leave it at idle for the 10 mins, you need to build some pressure to get the oil flowing around the various parts - not full throttle but blip it to 2500rpm every once in a while to get better coverage 🙂

[@giuseppecasara1143]

Drain the hot old oil and remove oil filter first, add cheap oil (2/3 liters- there is no need to reach the full capacity , just the middle of the stick ) and filter and go around 5 minutes until the engine oil reaches the right temperature. Stop the car and add Liqui Moly and idle the engine for 10/15 minutes, drain oil and remove filter. Put a new filter , add good quality Syntetic oil (the correct amount your car takes ,3,5-4,5 liters) and that's it . Use fresh cheap oil with Liqui Moly Engine Flush...rather than adding it to the the old dirty one.........This is my proper and personal way ......everyone is free to do whatever he wants , but it seems more logical to flush the engine with Liqui Moly and fresh and clean oil and filter....

[@SiliconPower74]

If you have an old engine, Carbon deposits may prevent or reduce oil burning because reduces the gap in a weared area. when you flush it, the engine could burn some oil due to the removal of that layer of carbon deposits. That said, all engines burn some oil, some more than others. Dont worry too much, just check oil regularly and change it as often as you can. Me personally gonna flush my ford fiesta engine tomorrow, first time in his first 93.000Km. I am not planing in doing it regularly, only once each 40/50.000Km.

I let the engine drain the oil for almost an hour and added some new oil to help push the last of the old oil. The old oil was pure black, it was only 13.000Km and 10 months old so I think the liqui molly did a good work. Meanwhile I changed the oil filter and diesel filter.
