Engine oil LIQUI MOLY or Shell

something you might consider is switching to Shell Rotella T6 5w-40.

you can find many testimonies to the benefits of using T6.

Liquid Molly 5W-40 is what I use in mine.

I run liquimoly and it has been great in every vehicle I've put it in. I run WIX XP filters. All my engines run beautifully. My ram 1500 tows frequent and gets ran harder than most.

My 2019 consumed maybe 1/2qt for the first two oil changes. Swapped to Liqui Moly last 2 changes and been zero oil consumption.

my personal analysis’ on my s54 over the past 7 years using LM 10/60 have all been perfectly fine with low wear numbers.

I've used both and have put over 50,000 miles on my B46 (b48) without any issues. I think the liqui moly might be a little quieter, but otherwise no difference I can find. I would not put a heavier oil than the engine was designed for. These engines are a little noisy IMO but that doesn't mean anything is wrong. I actually think mine is quieter now at 88,000 then when I bought it at 34,000.

Liqui Moly 0w20 6200 is what I run and a factory filter

Another happy Mann filter and Liqui Moly oil user. I currently use 0w40 because I’m in the frozen north, but used 5w40 previously.

My 1.8t is currently filled with Rotella T6 and I swear its eating less oil now (or maybe I'm getting better with my heavy foot)

Liqui Moly, Eneos have been my go to oils
