I have 0 faith that my mini engine will go 200k miles. 100k sure but anything past that is a crap shoot, as you mentioned far too much complexity with plastics everywhere, turbos, intercoolers etc.Detroit wrote: ↑Wed Feb 10, 2021 12:55 pmHard to connect reliability because engines in the 80-early-00's were kind of the sweet spot for reliability. Enough experience building engines to know what it takes to make them run forever, plus computer controls advanced enough to monitor things like knock and control timing, monitor oil lifemax225 wrote: ↑Wed Feb 10, 2021 12:48 pm
I mean this has been beyond confirmed:
BMW No free maintenance 5000 miles post 15000
VW Pre free maintenance 5000 post 10000
Toyota 5000 post 10000
Mini 5000 pre 15000/10000 post
Nothing about the engines changed, and most oil compositions stayed similar/same. Certainly not different enough, I.E 50-100% increase in oil capacity and additional filtration etc.
This is also coinciding with another different factoid... It seems like cars from the 90s and early 00s are the most reliable ones on record (MB/LR exlcuded). Anything more recent has had far more complexity added as well as oil change intervals far prolonged.but without the complexity of DI, fancy emissions system, and tons of boost. Engines these days are going to be throw away units, and like you mentioned I think we peaked with engine reliability past 100k miles overall. Engines are still engineered to go past 200k miles, but there's just so many variables for that, I think it's going to take a lot more to make an engine go 200k than before.
The taco however ... I’m confident in for 300k
