So I got some Fully Synthetic Motor Oil on sale. I don't know much about liquimoly because I just recently purchased my BMW but I was wondering if the longtime high tech was anything like high mileage oil that doesn't have anything to do with mileage but typically has a chemical that enlarges engine gaskets to stop oil leaks. Any gripes about this oil compared to regular full synthetic or anything I should look out for? Thanks!

Assuming your 335d still have stock emissions in place (DPF), any BMW Longlife-04 approved oil works for the M57 engine.
The LM website says that LiquiMoly 5W-30 Longtime High Tech has it.

The "Longtime" marketing implies it is suitable for extended (OE) oil change interval - not a "high mileage" additives.

PDS says:

Low SAPS fully synthetic motor oil for diesel engines.
Specifically developed for engines equipped with diesel particulate filters (DPF).
Use with extended oil change intervals as per manufacturer.

Hey thanks! I actually don't have my DPF in because it is not stock anymore. Not sure if that makes a difference. Should I still try running it or will there be more separate issues if I do or anything to look out for?

The LiquiMoly 5W-30 Longtime High Tech you have will still work just fine.

However, since DPF is no longer in place, your oil choices are more open.
You'll find lots of fans of Shell Rotella T6 5w40, Mobile 1 ESP 5w30, etc.

Just remember to use high-quality oil filter that is made in Austria: BMW or Mahle.
Mahle should come with all 3 o-rings, BMW branded one comes with 1 - you'll need to get other 2 separately

Minor correction. Orings, not gaskets. I swap all 3 orings every 3rd change using Mahle brand and then use the OE BMW filter the other 2 times (unless I'm out of Genuine filters). I change at 3000-3500 miles so I'm not concerned about other 2 orings going 9000 miles.

We are all different though so use Mahle every time if that's your preference.
