Hi fellas,
Wondering what practices people do in Germany to maintain their BMW's without voiding warranty...
What i mean is
Do you use your own BMW oil?
Do you use your own BMW approved oil?
what does the law say in general?
I know that in the US the manufacturers have to prove that any warranty claim failure was the direct result of using another oil that is not OEM. or the owner is at fault when he cannot produce evidence or proper maintenance and use of BMW approved oils.
Any input would be greatly appreciated.
