Engine oil LIQUI MOLY or Shell

Have used Mobil 1 European formula 0w-40 and liquimoly molygen 5w-40 in my 2019 golf r without any issues. Molygen holds up great to the fuel shearing from ethanol I run.

May get hate but I use in both of my is300s Shell Rotella T4 Triple Protection SAE 15W-40 Engine Oil the first oil change is nasty cause it has more detergent but after that you have much cleaner oil changes from that point forward.

I run [Liqui Moly Leichtlauf 5w40] in my car. Even though it's a 2015, it has a motor out of a 2019.

Ran Rotella T6 5w-40 in my stage 2+ (and beaten to hell) WRX right up to 120k miles when I sold it.

It's perfectly fine for the WRX, and it's what I use in mine, as well as its two previous owners. My car's maintenance records include two reports from Blackstone Labs detailing their examination of the Rotella T6 5W-40 oil and according to those the engine has worn very well on that oil

I personally swapped from 5w-30 in my OBXT to T6 5w-40 and have noticed a decrease in oil consumption (newish engine with 28k so that also helps).

I use and recommend Liqui Moly 5w40 leichtlauf. It's LL01 approved and is really good quality.

My 2012 Golf TDI with the DPF stuff states that it **MUST** have 507 00 5W30 spec diesel oil, not 505 00 or anything else.

E92 Changed the oil with Liquid Moly 5w40 and a Wix air filter and drove from Texas to Colorado. 39.2 MPG average!

Just got my first Blackstone oil report on this engine. LiquiMoly 5W/40, 9,098 Miles. Here' s their comment: "We think you've got the oil change interval dialed in pretty well, but with results like these, you could push it a little if you wanted or needed to.
