Hi,
I`m a Norwegian guy just that found this forum, there is a lot to learn in here, great place
I drive a Bmw 750IX 2013. This got a twinturbo V8 with the turboes inside the "V" and they run quite hot. Its been running on the Bmw twinpower turbo gold 0w30 LL04 oil so far. This is a "high" 30 grade with a Viscosity at 100°C (212°F) of 12.5, dont know HTHS but its C3 so at least 3.5 mPa.s
Alot of people on the N63 facebook group recommend to step up to a 5w40 oil on these engines for better protection so thats what i plan to do. OCI is 5k miles so i dont care about Longlife properties or fuel efficiency just wont whats protect the engine the best.
I have bought Liqui Moly top tec 4100 for the next two OC, this was recommended for this engine by the Liqui Moly support. It has Viscosity at 100 °C (212°F) 14,3 mm²/s and HTHS is at least 3.5 mPa.s, its C3. Maybe I'll stick to this oil in the future but i also had a look at some Motul oils and here is my question:
Motul has 3 different oils 5w40 with LL04 approval, they are all C3 but they have some small differences, so i wonder what is the most important properties to look after for best engine protection.
It is mainly the properties of hot oil I wonder because it is not very cold here I live and I drive the car very nicely until the oil has reached operating temperature.
