Not exact matches
Diesel
engines have a higher
compression ratio
than gasoline ones do, and more
compression means more power out of the same amount of fuel, she said.
We probably all know that using premium grade
gasoline in a low
compression engine (less
than 9.5:1) is nothing but a waste of money, but what about medium
compression engines with a
compression ratio between 10:1 and 11:1?
Heavier - weight components are used in some areas to handle the higher
compression ratio — generally more
than twice that of
gasoline engines
As far as higher mileage, high -
compression engines develop more power
than low CR ones, which will help with mileage, but part of the reason diesels get higher mileage is b / c diesel fuel contains more energy per gallon
than gasoline — so there won't be any mileage boost from this aspect.
