As they say, optimum would be a Cummins in a Ford, That being said, there isn’t a GM in that equation. :D I guess you’d say some of us would rather have a Ford 6.0 or 6.4 before a GM. So what?
Anyway, back to the ad, I’m sure I can build a new gasoline engine truck thats more than the most basic diesel truck. That doesn’t mean much.
Kayteq1, of course, an exhaust brake is diffferent than a turbo brake, but the explaination of why diesels have exhaust brakes or turbo brakes remains. The real point is that gasoline four stroke engines have “engine braking” by default. Always have.
And sure, it is possible to have a poorly maintained or mistreated engine of any type of engine that isn’t trustworthy on mtns.
A final obvious statement, there are engines of all types that are doing just fine, and every engine has tradeoffs. Pick what you want to tradeoff, but don’t pretend that your “perfect” solution is “the” perfect choice for anyone else.
