LIQUI MOLY › Engine oil

I use it on my 2016 S5 and it’s wonderful. It’s basically the same as Leichtlauf just with the friction modifier and UV capabilities if you need to spot an oil leak (only in the first 300 or so miles because then the oil gets too dirty to work with the UV). I’ve heard the friction modifier works well in older performance cars due to the increased wear of their engines. Yes it’s technically not approved but you won’t go wrong with it.

Pros: wonderful, friction modifier, UV capabilities

Cons: UV works only short term

I’ve done both and extractor takes out like 97% of oil. I still had about a half cup when I pulled the plug.

Pros: extractor removes most oil

Cons: leaves some oil

Warning light:

My B9.5 S5 went through a quart about 3000 miles into the last oil change. This oil change that im on now I havent had the light come on and im at about 5000 miles which is when I change oil. I started taking mine to an Indie shop and they use Liqui Moly oil plus they add this little bottle of addative thats supposed to help lubricate the piston rings better.

Pros: no light come on

Cons: went through a quart

Vehicle: Audi S5

Mileage: 8000 km
