    I think so .

    Although 1.9 TDI is considered reliable in Europe (especially the weakest 75hp version) , being a diesel inline 4 , so every rule has its exceptions

    depends on which engines, an iron doodoo will outlive the sun and a northstar has already shit itself before I finished typing this

      kek whatever they put in those old mail trucks must be low compression impossible to kill engines

    >have v8 chevy trugg
    >rarely revs past 2k rpm on normal city driving, sits at a cool 1600rpm while going 60mph on the hwy

    >1.5l japanese shitbox
    >constantly have to rev the shit out of it to 5k+ rpm during normal city driving because otherwise it wont fricking move
    >screams its ass out on the hwy sitting at 3k rpm @ 60mph

    so im pretty sure the 4 cylinder is taking a lot more wear then the big v8. That said 4 cyls are much easier to work on if something does go wrong

      All other things being equal an I4 is slightly more harmonically balanced than a V8 so there will be less wear on the crank bearings. I6 and flat-4 are theoretically better and more-reliable than I4 or V8.
      A large undertuned engine will generally last longer than a smaller one pushed to the limit from the same design and materials, but this isn't technically the question you asked.

      this is kind of the crux. *most* vee eights output decent hp and have higher displacement and *most* 4 bangers are high strung, low displacement and often revved out/ragged on (or turbo'd and still kinda slow) because you can't otherwise take an on ramp effectively. so if we're comparing shit available and not just theory, and adjusting for abuse or lack of maintenance, most V8s on the market should outlast most I4s

      I have a Mazda3 and I don't think I've gone over 2k rpm once in the last 10000 miles in highway driving, only rarely in city driving.

      Doesn't mean anything, I had a Honda civic i would abuse and never change the oil on and it lasted well above 220k miles

    Bigger displacement and simpler design will last longer but it really depends on how it is used and maintained more than anything.

            The 5.4 is a really shitty engine, don't get me wrong, but not even close to the worst. If you do the cam phasers and plugs, they're not that unreliable either.

            My Modular 4.6 sits at 1,300 rpm at 65 MPH, and probably runs better than it did 50k miles ago.

            bro nip shit at 5k will last 10x longer than any pushrod or burgershit v8 will at 1500rpm. American manufacturing is trash. literally bottom tier junk made for nogs to rent.

    engineering specifics contribute so much more that harmonics rarely play a role in lifespan, there are terrible straight 6's and fantastic v8's

    ring tension is so low now we're seeing 200 and 300 thousand mile rebuilds where the blocks still have hone markings, where anything around the turn of the millennia would be losing compression and needing a overbore around 100k mi
