M3 E9X breaking in at 50k miles

PetrolFumes · 05-23-2012, 10:59 AM

So a BMW mechanic told me these engines truly break in around 40-50k miles. Anyone else ever hear this? Is it even remotely true..

Total nonsense.

you might not want to trust that BMW mechanic working on your car

Makes no sense. It's not a pair of loafers.

I have a strong suspicion that he was joking. Like "Nah that thing will run a lot longer, it's just getting broken in!" or something.

No he was serious cause I test drove a 12 and told him my 09 felt a lot stronger after pulling it back into service and that's when he said it

I actually somewhat agree w the guy. I have an 2008 (07 build) w/ 57k miles and it feels stronger n faster than ever! No joke.

Yeah and w/ out mods?

IntegraXTR · 06-17-2012, 04:10 AM

this reminds me of when i owned my NSX, the magical "break in" number was 75k miles. it was actually dyno proven with the same car (tho i know dyno runs can vary due to conditions etcetc).

the Honda engine builder stated that the motor at that mileage finally is "broken in"...

i hit that number on my old NSX and yah i didn't notice anything....haha
