Oil & TBN
G’day
I did a lot of research about BMW approved oils and i use (insist) on Mobil1 0W-40 (which is approved by BMW & Mercedes AMG & Porsche).
I use High TBN (Total Base Number) oils because they have a greater ability to resist engine wear and tear (pollutants associated with the combustion process) .
And I have used this in both my Bmw 135i M Sport (N55 Engine) and now my M5 with great success .
I change my Oil and Oil Filter every 12 months regardless of km/miles.
Our family has owned Bmw’s for over 40 years and we are pedantic about Annual Oil & Filter changes to protect our engines. Our engines are immaculate on tear down for overhaul/heavy maintenance.
I do not get/suffer any Oil Burn/Consumption between Oil Changes .
Cheers
Bruce
