I realize there must be a lot of variables, and perhaps you can elaborate on the more important ones, but generally speaking, is a 6-cyl motor going to be inherently more durable than a 4-cyl, and an 8-cyl more durable than a
6-cyl?I would think a more powerful engine in the same car would not be working as hard, and would therefore last longer. But what if the bigger engine is in a proportionally bigger vehicle? Is there anything about the mechanics of the larger engine that makes it more (or less?) reliable?
Thanks.
