Been reading around about ways to improve fuel economy. Couple things I keep coming across.
Direct injection diesels are said to be 10% more efficient than indirect injection. Something about flame propagation spreading more evenly and completely during the combustion process.
Add in another 5% efficiency for modern fuel delivery metering strategies. No smoke or haziness makes for better economy.
Most guys in newer diesel trucks are getting 14 to 19 mpg, in 4wd platforms and depending on driving conditions.
They're getting 10 to 14 mpg when towing 10k to 15k pounds.
Seems about the same as a good running IDI?
Do the newer rigs just weigh so much that there is no improvement in how far they can drive?
