Best oil hands down
Size: 5 L
This is the only oil I use now, my mechanic recommended it. Works great in my Mazda3, runs smooth and no leaks. More expensive but, worth it.

Best Oil on the Market
Size: 5 L
I’ve used this and only this in my 15 Scion FRS since I bought it . I used to change it every 5k but I retired and now it’s a once a year oil change with less than 5k per year. The car has never had any issues with this oil . Since NASCAR changes oil in the cars every 500 miles I don’t whine about changing it once a year. $40 for oil is better than $10k for another built motor

I just got it changed about 30 min ago and the engine sounds like a little cat
Size: 5 L
My Audi factory setting says I should use VW 508.00. Somewhere online it says 5w-40. It's 82000 miles and I decided to give it a shot to go 0W-20 which is what VW508.00 is. I just got it changed about 30 min ago and the engine sounds like a little cat. The gas pedal feel is very smooth, there's definitely less resistance when pushing forward. In Sports mode driving, the engine is not as loud and the lag or drag is noticeably less. And when it hits 100k, I will do a engine flush to see if I can get further improvements. So far, I really love Liqui Moly. I used to use it on my S500 and it was very smooth. A little more money goes a long way! Don't settle for less for your German cars. Update: I just did another 1000 miles in a week to Vegas and back. The fuel economy improved about 20%. The power increase is amazing. I could notice when I am going fast, the sustained speed at high speed is easy and continuous, It doesn't just hit a snag when your foot is off the pedal. And the engine is definitely a lot quieter and smoother. I am amazed at the overall improvement after using this oil. No other oil will do from now on.
