Engine oil LIQUI MOLY or Mannol

Liqui Moly TopTec 4100 is good and cheap. Castrol oil is, indeed, not worth the money.

I currently use Liqui Moly 5w-40 in my 02 WRX and it loves it.

Been using Mannol 0w-20 fully synthetic for 3+ years now for my Jazz, engine is smooth, almost all the time I felt the car would always glide and it cruises easily, fuel consumption is great as well as long you are light footed. Mileage is now at 300000km (oil did not reduce at all within that 10000km service interval)

It's run fine on Mannol with over 25k miles so far.

I like this oil, I believe it was Castrol Syntec from the factory (says so on the oil cap) but it became slightly hard to find and the Liqui Moly has been great oil so whatever. I changed my oil last year at about 9500mi and it didn't even get dark until about 7k miles.

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.

I run OW-30 Liqui moly that doesn’t burn any oil either.

I switched to liquimoly oil, mine uses a quart roughly every 3k miles but no issues.

I use Liqui Moly 5W-40 which is on the VAG 502 and 505 list.

I've noticed going from cheap synthetic 5W-30 to Liquimoly 5W-40 seemed to help a little with my intermittent light issues.
