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.

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.

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.

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.

This is a super product,i have a car that has a very noisy tappet,i could not afford to put the car in to have it repaired,so when i saw this on the website,i thought i would give it a try,its amazing,it took a few days to work,but now the engine is much quieter,and you can barely hear the tappet,i am so pleased and impressed,there are no negatives.
