Liqui Moly is fantastic oil. It's a pretty fair price for me, so I always run it and have had great oil analysis when using it.
Pros: fantastic oil, great analysis
I was using Kirkland synthetic before for topping off and other American oils for oil changes I’m sure, but then I went to a euro auto shop and they switched out for a German filter and oil, LIQUI MOLY, and I got a significant increase in mileage.
Pros: significant increase in mileage
Vehicle:
Volkswagen
Liquimoly molygen 5w40 doing great in my 313k motor.
Pros: doing great
Mileage: 313000 km
I use liquimoly leichtlauf 5w-40. Bit of advice: these are VERY easy to overfill if you're not careful, so refill slowly. Put in less than you think you need, once it registers on the oil level sensor, then start the car for a minute. After that, leave if for a few hours to drain before continuing to fill.
Pros: easy to use
Cons: easy to overfill
Vehicle:
Porsche
amazon.ca has Liqui moly TOP TEC 6200 SAE0W-20, VW508 00/509 00. Been using this since day 1 on my 2021 Tiguan with no issue.
Pros: no issues
Cons: price is not cheap
Vehicle:
Volkswagen Tiguan
I buy Liqui Moly 6200 from germanparts.ca for about $70/5L. Our Tiguan consumes a lot of oil sadly, so I buy a lot of it. My mechanic recently recommended using Liquid Moly 2331 (Leichtlauf) 5W40 to see if it helps with oil consumption, and have had that in for the last month or so.
Cons: high oil consumption
Vehicle:
Volkswagen Tiguan
Liqui Moly 0W-20 LR for my F-Type-R. Doesn't use much oil, so cost is somewhat irrelevant.
Pros: doesn't use much oil
Had an E63 that I recently traded with almost 200K miles, a few months ago I scoped my 1 and 5 cylinders and they had what I would consider normal to no wear. So as a DIY'r, here are my observations, This is a bigger issue in the States than it is in Europe. ... Keeping the engine clean is key. Frequent oil changes no more than 5k mi, using quality oil and fleece filters, formerly a Mobil 1 guy, now using LiquiMoly.
Pros: normal to no wear, switched to this brand
I've noticed going from cheap synthetic 5W-30 to Liquimoly 5W-40 seemed to help a little with my intermittent light issues.
Pros: helped with light issues
Cons: intermittent light issues
