Engine oil LIQUI MOLY or OEM BMW

I use the Leichtlauf High Tech. Really helped my higher mileage SQ5 with chain rattle.

I personally use Liqui Moly. I've tried Castrol, Mobil 1, Amsoil, etc. and my BMW (E85 Z4M) runs noticeably more smooth with the LiquiMoly.

I’ve never had any issues with 5W40 Liqui Moly Leichtlauf.

I run liqui moly molygen 5w 30 oil in mine. Runs ultra quiet and quiets lifter tick. Runs nice and cool and runs like a champ!

I wouldn’t put anything other than Liqui Moly in my Benz. I used to take my car to Wheel Works, but after long drives, it would smell like burnt oil. Switched to LM and started charging the oil myself. I’ve never smelled anything after that for years. It makes a difference for sure.

I’ve have always used higher quality oil like liqui-moly (0w-20 till 60k kms)

I might add use the best oil you can find - this will keep your PCV system spotless and other good things. I always use oil to the severe service Volvo spec listed in the owners manual. I now am pretty exclusive to the LiquiMoly line. I insist on 3rd party certification

Liqui moly for me runs about 4-5 degrees lower than OEM for my GTI. not sure if the same temp diff exists for the R but I did some reading on this. Perfectly normal.

If changing oil at 15k kms interval has served you well for 2 lakh kilometers, then I'd recommend sticking to it instead of switching to an oil with long service life. 30k kms oil change interval claim is a big stretch. I've used LiquiMoly 5w-40 with my Polo 1.2L TDI. Drove it close to or may be more than 20k kms over the course of 3 years until the check engine light came on. Immediately changed to OEM engine oil and for some reason the check engine light went away. Except with LiquiMoly, I've always changed engine oil at 15k kms or 1 year whichever was earlier. This is what my car's manufacturer recommends and I'll follow it even if I use LiquiMoly again.

It’s not any better than Walmart Castrol, just double if not triple the price. I’m 160k tuned!!!
