G’day Patty
Interesting (and happy to be corrected) because the product data sheet does not say this :
https://pim.liqui-moly.de/pidoc/P001...40-31.0-en.pdf
Liqui-Moly make fine products but it’s not available in Australia.
Our engines generate lots of heat because of the “hot vee” design and I use Mobil 1 0W-40 because of the high TBN (Total Base Number) .
It holds approvals for Porsche/Mercedes AMG/Bmw .
I have used this oil on all of my turbocharged engines since 2010 with great success .
Most important is that this oil flows very well when cold and hot ; and thus protects the engine (hence the 0w and 40w part of the oil viscosity).
Ps : have you checked the recall status on your car from Bmw Australia:
#1 :Cooling Protector Mats for the Turbocharger Cooling Lines
#2 : Drivers TAKATA Airbag
All of this is covered by BMW Australia
Cheers
Bruce
