## Questions & Answers

**Q: Difference between this and the liqui moly lifter additive?**
A: Just had a look at both products and the picture looks the same and so does the description so I would say one is for European Markets and the other is the English version but same thing. By the way it does clean the lifters and reduces tappet noise as long as your car does not have serious issues. I use it at oil changes that I do myself and leave 300ml for this oil to be added with engine oil so as not to overfill. I also do regular oil changes and every other oil change this is added.

**Q: Where do you pour this into?**
A: Hi, the additive goes into the engine , you might get slightly better results if you change the oil and filter at the same time, I found any slight improvement was short lived.  But some people swear by it.  Hope this helps.

**Q: How effective is this product at reducing hydraulic lifter tapping noise? Do you leave this product in the oil or does it have to be drained out?...**
A: Worked well on my bmw320 d compact
