VPO Liquid Boost - STREET Oil Vitalizer

I have a 2015 BMW 320i that have 63k miles on it. I put 8oz or half a bottle in I noticed it idle quieter and acceleration seems smoother.

Honestly it works amazingly, does exactly what it says on the bottle, worth every dime.

The ticking sound that my2016 lexus was making has been removed. Thanks
