N20 Longevity

[Boltz]

Today an E89 2014 18i pulled up next to me and the driver complimented me on my Zed. We got talking and to my astonishment his car that he had from new had covered 143K miles!!!!!!! The guy was a GP and covered surgeries all over the country. He said his car had never let him down once and was still going strong. So nice to know that there are N20s covering some high miles with no issues

143k miles isn’t bad, not as impressive as this 28i though, no issues either

Thats impressive.
At my current rate of usage it would take me 125 years to get there.

When you think about it why wouldn’t they last as long if not longer than preceding models?

Given the design guys have all the accumulated experience of the preceding models, later technologies etc they should last longer providing the design compromises associated with emissions / economy don’t get in the way...

The N20 engine powered several 18i 20i 28i models 2,3,4,5, Z, X1, X3, X4..several of those are at 100k+ miles..

Most of these engines provided they get regular oil changes of good quality will run for ever..

Most of their lives they are running in the sweet spot of life expectancy..1,500 - 3,500 rpm..

Stop start / short journeys kill all car engines and they were one of the first to suffer the curse of stopstart..some observers think most of the cam chain related issues are a combo of inadequate oil changes and stop start..

I think the next question the doomsayers will ask will be yes ‘ but what if you tune the b@ll&cks of it?’

I've tuned the bollocks off everything I've owned with the intention of just buying a new engine if the worst happens but I'm still waiting!

I think if you respect the known limits and maintain an engine well you can get away with a lot. Thrashing an engine from cold and sticking to 20k mile oil change are more abusive to an engine.

Mine gets a saints life at that rate and should last forever!
In essence it’s basic engineering empathy.

Well that’s a line of thinking I’m drifting into..I already do the oil and cold start bit...looking forward to ‘tuning the bollocks’ / ‘respect the known limits’ part !
