Product reviews2x Liqui Moly Hydraulic Valve Lifter Oil Additive Treatment Petrol Diesel Engine

May Not Be What I Needed for my vehicles motor.....

Pro - was easy to pour into the engine, instructions on use I had to Google. But basically pour it in, let vehicle motor idle for 10 min and then take it for a run.

Unfortunately there has been no definite change to my motor or the sound coming from it. So either my motor hydraulics are too far gone for its use or it is not the lifters at all. (The vehicle has done over 115 miles since adding the product.

On the fence ith this one

Seems to have made a subtle difference but not sure, done around 1000 miles since adding and I think it's done something, not a lot mind but a little for sure.

I was hoping for more of an improvement but better than nothing.Read full review...

Some you win - some you don't

It was easy enough to use and I would recommend trying it before spending a fortune on mechanical work but it made no difference to my hydraulic lash adjusters at all. I was hoping it would quieten them down and save a head overhaul.Read full review...

Does what it says on the tin

I recently bought a Renault Scenic that the previous owner never lifted the bonnet to check the poor car's fluids. No surprise then that the oil level had dropped dramatically and the hydraulic tappets were very noisy as a result of that. I have bought these 'voodoo products' in the past that promised much and delivered little, so I was just a bit sceptical when I bought this one, but the alternatives didn't bear thinking about so it was at least worth a punt. Nothing ventured, nothing gained as they say.

Oil cap off, poured the contents into the engine and within a mile or so the tappet noise certainly was greatly reduced.

All in all very pleased with the outcome.Read full review...

Easy to use .Made by a well known German company making oil for every use .

With older cars you do get a tick from the valve gear .This product helps to eliminate it .

Tappet fixer! Amazing.

I'm not one to write reviews, by for this product I have to!! Delivery was within the time frame and was very happy.
My freelander has had loud hydrology tappets for a few months I tried the wynns hydraulic tappets but that was a load of crap! Didn't work and was a waste of money. I put this stuff in my land rover about a week-2 weeks ago.... it had to take a few days to circle around with the oil which I gave benefit of the doubt. It has worked magic my car is now purring no more ticking no more crap. Amazing I'm so happy with this... thank you so much for being better than that wynns crap!

I recommend this product 100000% it may take a few days to circuit the vehicle but it works. And it's cheaper!!Read full review...
