Great stuff !! You can definitely tell when it’s been added to the oil. You can feel the difference!! God Bless

Doing valve replacement, figured I try it out.

Put bottles in a Camry and two Volvos. The impact was very noticeable. You can feel the engine running smoother (pistons move more freely). I strongly encourage you to give it a try, I highly doubt you'll be disappointed. Sidenotas been great with support (videos have been he -FCP helpful and the product suggestions have been great).

MOS2 is a wonderful additive for smooth running engine, quiet at idle, anti-friction properties have shown results between my oil changes & the fill-in-the-gap of all the micro improperties in the metal of the engine block and components (like cylinder wall to piston contact) fills in the micro-pores like Ceretec is made to do but this lasts only for an oil chnage at a time, not 30,000 miles,

Great for S54 motor

09 E90 335 n54 with upgraded turbos and all supporting upgrades> Used with my previous oil change LM leichtlauf. After about 3k of hard running I will begin to notice the oil temperature has a harder time recovering, with this, the oil bounced back up to the 4k change interval with no change in oil performance. Economy improved as well but wasn't too concerned about that piece.

Started using this 10,000 miles ago (ish) as I’ve become a believer in all things Liqui Moly. As others state it’s hard to say what exactly it’s doing, but it’s not hurting anything and between this and using Liqui moly Molygen for oil changes my oil temps are lower. Assuming this is more the Molygen however it makes sense if there’s more lubrication on internals it would make less heat, and when coasting my oil temps go down faster and will stay lower when compared with what the dealership puts in.

I noticed the engine is less noisy than it was. I could tell the anti friction is doing its job. I strongly recommend this which will prolong the life of the engine

Use it in every oil change with Molygen 5w-40 when I am not using Ceratec. Sometimes I would use it in addition with Ceratec if there is an extra bottle sitting around. Helps quiet down my engine and makes it smoother.

I put this anti friction additive in both my cars every time I change the oil. Big fan of all Liqui Moly products and still have yet to have engine troubles out of my BMW or Mercedes. Both have over 100k miles so I highly recommend this as preventative maintenance
