Driver A changes his oil every 25K as recommended by BMW and driver B changes his oil every 10K, both using the same brand and viscosity. after both the car have reach.....lets sayyyyy 200,000KM, we dismantle both their engine and have a peak inside, what do u think will the difference be? or no difference at all?</p></blockquote><p></p>
