Thanks, sorry for the late response. I also do not want to open another Oil Anslysis thread.
What you are saying has to quantify to- location, vehicle location production, heat, climate and the killer, temp and how much you have on the clock..
I have a EU Manual and it's identical to the US one. It specifically states -Viscosity ratings (SAE) depends on the regional climate- APPROVED OILS 5W-40 and 5W30. And we all know Castrol paied a lot to get that logo on our N54. Caps.
Now, it all comes down to preference based on the above.
I know what sheering can do, on cold or sprinting driving.
Each to there own but thankfully i have found the right oil for my car.
Check the manual. Viscosity changes at all levels, not just warming up or settling the car....think about your oil while driving it. Unless you just turn it on and off.
Pls pls guys read posts on bobstheoilguy.com and the manual.
I really hope this help
