Will a 1.0-litre last as long as a 1.6 diesel?

Will a one-litre engine last as long as a 1.6 diesel?

Hi John,

That's kinda a 'how long is a piece of string?' question, as no two engines are created equally. I mean, every different 1.6-litre diesel engine has a different realistic life span. And while it's reasonable to presume that a diesel engine is designed to be driven over higher mileage, I don't believe that manufacturers aim for 'worse' durability for their smaller petrol engines.
