Worked great for me!
My well maintained mini Cooper still sounded like an old taxi when starting from cold. This quietened the engine almost immediately. Runs smooth and quiet now. I would recommend giving this a go if you have noisy lifters.

Hydraulic lifter fluid, didn't work for me!!
I'm not sure of this hydraulic lifter additive did anything or not as it did not solve the problem. I was going the a process of elimination and this was the first and least expensive thing to try.There was a chance it may have worked but it didn't seem to for me!!I tried other things, ended up selling the car with the lifters still tapping as much as they did before I did anything. If it was a mechanical problem it was going to be too extensive to repair.

Simply did not work !!
Added to engine after oil and filter change to hopefully cure a light hydraulic tappet clatter at cold start up, it never made the slightest difference, simply did not work at all, 1000 mile now since and still the same, dont waste your money folks.
