hydraulic tappet cleaner additive

abceire

Has anyone tried these?
My engine is a bit loud, kinda tappety sounding, more so when cold started but can sound a bit loud even when warmed up.
I bought the 1.2 petrol opel corsa off my mother, it only has 67ooo miles on it. It wasn't driven hard at all , did a lot of small trips were it never got warmed up properly.
I got the additive but it say just put in while the car is warm and drive as normal. I'm not sure if you just put it in and leave it in or change the oil after a bit. I was going to change the oil soon. But wondering should I put additive in before or after I change the oil.

Usually you put in and leave it (read the bottle). Id put it in before the oil change to see if it helps (they are meant to clean the channels on the lifters) and get the car running better prior to new oil. Id also put in some good oil, not the cheapest on the shelf. Use Castrol or Maxols "What Oil for my car" tool on their sites to find out the recommended.
