Hi folks,
I recently bought a brand new car (N55 equipped BMW), and wishing to keep it in the best shape possible I dumped the factory fill of oil after around 30 miles, in an effort to get rid of any debris in there from the initial bedding-in of the piston rings.
Only now, after having done that am I wondering whether I've inadvertently dumped some break-in additives with the factory fill, or whether these generally aren't used any more, due to BMW's 20,000 mile/2 year OCIs and smaller tolerances in modern engines? And therefore whether it's worth getting a break-in additive to put in myself, or whether that will do more harm than good.
I also plan to change the oil again at 1200miles, at the end of the period that BMW say to keep RPMS below around 4000-4500, which presumably is the full break in period for everything to bed in.
After that, from what I've read here and on other forums I was thinking of going to a 7500mile OCI, as seemingly BMW's own 20,000 mile/2 year OCI is too much even for the best current oils, due to high fuel dilution and high oil temps in this engine.
Any help/advice anyone could give would be greatly appreciated.
Many thanks
Russ
