It's a myth based on 40yr old technology that diesel will last longer.

Hmmm... If one engine needs to operate around 5000 RPM to pull a load while the other can do it at 2500 RPM, which do you think last longer?

So my gasser pulls my trailer at 65 mph 2000 rpm all day long. So now which one lasts longer?

Just a guess but odds are, same terrain and load, my diesel would be turning maybe 1600 RPM. I try to keep shift points under 2000. So yes, diesel. Now let's talk about steep hills... :C
