Liqui Moly 20004 Hydraulic Lifter Additive

Good product

Work as advertised! Reduced the tapet noise to greater extent. Quiet the engine noise that was intruding into the cabin.

Efficace sur une 320i e36. Le clac clac au démarrage a été complètement réduit et a quasiment totalement disparu. Néanmoins, il m'a fallu rouler un bon millier de Km après avoir mis l'additif pour qu'il commence à faire effet

Sehr gut

Brilliant product, the tappet s are really quite when cold engine

I use this in two of my cars, a 2008 Chevy Avalanche and 1976 Subaru DL. It works well in both, but definitely better in the Chevy. It’s super easy to add to any engine, but I generally just add it to fresh oil during the oil change. It pretty much immediately eliminates the lifter noise that develops towards the end of the oil change interval. Plus this is from a trusted brand at a great price.

Happy. It cut down the tapping sound in the car. Recommend
