## Overview

LIQUI MOLY 5200 Oil Sludge Flush is a 300 ml premium engine cleaner designed to dissolve harmful sludge and deposits inside petrol and diesel engines.

## Description

Effectively removes contaminants, increases operational reliability, prevents lubrication deficiency, and gently cleans oil holes, screens, and ducts to prevent damage.

Review: squeaky clean engine must use before every oil change - this thing is a miracle worker. you have to put it in with the old engine oil and run the car as normal for 300 miles. this thing will clear any sludge or sticky oil inside the engine. then use the normal flush 1L from liquid moly. the one with black cap. the 1L flush is to be used just before you drain the oil. the 1L flush needs to go in to the engine and let the engine idle for 15 minutes. this old sludge 5200 is sort of detergent / dental floss that works in working engine and the 1L LM engine flush is like listerine that you use after brushing. . this combo will leave your engine squeaky clean and the new oil will remain transparent for nearly the next oil change. it can be used in relatively new engines . machenics will tell tall tales of not being good for engine. same as doctors will tell tall tales of caffeine killing you . trust me this is the good stuff and it will prolong the life of your car and it will drive smoother and cleaner. just dont use this 5200 thing above 500 miles and dont rev the car at extreme rpm . drive as an old man and dont forget to use the regular engine flush right before draining the oil for that added listrine effect.
Review: Excellent product. - If your car is well maintained and serviced at regular intervals with correct specification oils then most likely you'll be not able to notice any difference. But if you own an neglected and/or abused car then there's a high chance to experience how LM 5200 works. My Corsa turned out to be the best example of negligence and abuse by previous owner. Noisy, smokey and sluggish engine suggested replacing or at least major repair, but I decided to try "revive" it cheaply. The first dosage made a small but noticeable difference to the engine behaviour and fuel consumption. So I flushed the engine and gave a new oil and another can of LM 5200. But instead of do around 120 miles I decided to leave it for longer. Especially that I was aware that mostly I am driving "within around the chimney" only and the engine has not much time to reach the full operational temperature. So I drove with it for over some 500 miles and that was the key. Compression is back to normal and there is no need to replace valve rockers nor lifters, and no need to replace bearings. Unfortunately timing chain must be replaced but not urgently. Power level and fuel consumption is satifactional - change from average 340 miles per tank to 410 miles per tank. Conclusion is that less than 25 quid spent for this treatment has saved me around a 1k for engine replacement. Am I happy? Who wouldn't be? UPDATE: 1.2 CORSA have now a new owner ;) I have bought myself another one Corsa but newer and with 1.4 16v ecotec engine. In this case it was clear immediately that highly neglected engine will need few repairs or even replacement. Especially that the black sirup pouring from the engine and smelling like a mine of sulfur, was not leaving much hopes. So the use of LM 5200 was mostly to establish whether the engine is worth repairing or not. As previously, compression and oil pressure has been fully restored after 2 oil changes with addition of LM 5200 and some 600 miles but entire timing system must be replaced as engine makes noise like a diesel. So, this time no spectacular achievement was made but I have found LM 5200 still helpful and I highly recommend it, especially for Vauxhall's engines which are known from frying oil and making dangerous sludge. BTW 1.4 ecotec is less than impressive on petrol. 320 miles is all you'll get in town, even if driving like a nun. Corsa D is simply too heavy for the 1.4 naturally aspirated 90hp engine... Or maybe it's just my right foot... XD

## Questions & Answers

**Q: how long do you need to leave this in your car**
A: Manufacturer is saying 'between the words' about distance in ideal circumstances when engine is fully warmed up and you are driving continuously for recommended distance. In real life, when most people are doing 20 miles daily in average, it is necessary to keep LM 5200 inside for much more miles - 500 miles or even a bit more. If you are using mineral oil or semi-syntethic oil (synthese technology - marketing trick used by manufacturers to mask mineral base of oil), especially if this is a cheap budget oil, you should consider to use LM 5200 before every second or third change of engine oil - I am saying that from my own experience based on Vauxhall engines.

**Q: Would this be any use for clearing fuel line sludge in a two-stroke garden tiller where oil and fuel are pre-mixed?**
A: No, there is separate product line for 2 stroke engines.

**Q: Can this be used at the same time as the engine flush**
A: Sludge Flush and Engine Flush are different products in this how they work. Engine Flush can be used only for oil change - car is parked with engine running on idle for average 20 minutes before oil drain. Idea is to KEEP engine internals clean.
Sludge Flush is used while driving as normal for at least 120 miles (may need even more - 300-500 miles depending on internal cleanliness) with the full operational temperature of the engine, to get through various types of residues from oil ageing products such as varnish, gunk, tar, etc. which if in excess will cause clogging of oil channels and jets.
So, first let the Sludge Flush do the worst job for one or two oil changes, and then to keep effect for long use Engine Flush every one or second oil change. Don't mix both.

**Q: How do you user this**
A: Add this to your engine crank case when you are about 125 - 150 miles from the routine service. Make sure to use the right oil to additive ratio i.e. 6% additive. For e.g. if your car holds about 8000ml of engine oil, you will use 453ml of this additive. Be sure to check the oil level after adding the additive using the dipstick. If in case you are over the max mark, then remove some oil. Also, make sure not to drive too hard with this additive in the engine. I would recommend not doing more than 65-70% of your max revs. This additive is milder than regular engine flush but as it stays longer in the engine it cleans out better as it is able to get to places normal engine flushes aren’t able to. If your engine is high mileage then optionally check the oil screen and clean if needed. Hope this helps :)
