Engine oil LIQUI MOLY or Castrol

I used Shell Rotella T6 initially on my 2006 BRM...but have switched to Liqui Moly Toptec 4100 and find the motor runs smoother on LM over the Shell.

Been using the molygen one, noticed a small reduction of oil consumption and better idling than Castrol (VW recommended)

I use the blue bottle 5w-40 on my 2.5 Mk5 Rabbit.

Runs quieter than when i used Castrol High Mileage.

About $22 for 5 Qts. of Castrol (you can buy it on Amazon or at Walmart for a decent price). Filter is about $4.00 or more if you buy a premium filter.

On my 2016 GTI with 211K on it, the only oil used was Liquimoly. From 0 miles to 200K miles it burned a quart every 3500 miles and that never changed at all.

Germany, 320d, 2008, 280000km, Castrol Edge 5w-30. Every 15000km

Ive been using Liqui Moly for my E90s for the last few years now. Nothing but good results from my analysis reports.

Castrol high mileage 5w-30 every 3 to 5k

Any other oil I have tried made my lifter tick super loud in cold weather

I use Castrol Edge 0W-40 in my '08 328, N52. Based on used oil analysis from Blackstone Labs, I'm at a 6K mile change interval.

Liqui Moly Leichtlauf (the dark blue bottle) 5w40: This is the oil I ran this sumer, and I'm on my second oil change with it. This oil burned about 2 quarts during both intervals, but did not seem to thin out or break down at all.
