by TOP CRITICAL REVIEW

Doesn't do what it says on the tin !!

Had low oil pressure on idle. Ran cleaner through it before oil change. Unfortunately no change so had to drop new oil and replace oil pump. The new oil ( 20 minutes old) was absolutely black and so was the oil pump and all visible internals. Was looking to see things a bit cleaner than it was after all the claims made about this cleaner especially on a 48k engine.Read full review

Does what it says on the tin

Easy to use. Poured into engine and down dip stick tube. Car runs better and sounds quieter once full oil change was done. Essential for a car that does short trips to work and back with the occasional long journey once/twice a month.Read full review

Had a oil warning light on the dash come up, used this to flush any oul particles stuck around the system. Seemed to work so far so good. Recommended

Made a noticeable difference.

Tried this in my 2005 freelander as it was becoming a bit sluggish to start. Added the moly and ran engine as instructed. Changed the oil and definitely notice it's easier to turn engine over on starting. Idles quieter too.

No sign of any oil leaked so far which some reports suggest can happen when cleaning the gunk out exposed flaws in oil seals on old engines.

High quality product

Use it every oil change @ 10,000 miles and the old oil is a nice honey colour at every oil change. Engine is silky smooth and the car is 10 years old and petrol. Car has now done 160k and running like a dream but then it is a Toyota. 👍Read full review

Good quality engine flush.

I have always used Liquid Moly at every oil change for many years and have not noticed any sludge build up in any of the cars I have owned. Currently I own a Jaguar F type 3L S V6 and maintain it my self. It's not cheap but I think it's worth the extra for a tried and tested product.Read full review

Will use every year

Last year my oil change was nearly as black as oil that came out. This year it was much cleaner and saved me from removing the oil sump. Very Pleased. Will use this every year.
Cheers!!!

Excellent at cleaning oil system

used in an engine which had not had an engine oil flush for many years. The apparently cleanish oil in the sump became thick black after using this product showing how dirty the oil ways had become. The engine is now quieter with higher oil pressure. Will use regularly from now on. Would recommend this product to anyone. The engine it was used on is a 55 year old 2 litre straight six.Read full review
