Fuel Efficiency questions

Each person built the equation different, but yeah 66k is the consensus. It's kinda mind blowing though right? Not super encouraging to ditch the old truck which still functions just fine.

Not really mind blowing. Buying to replace a paid off vehicle strictly for fuel economy rarely makes sense as it's all diminishing returns. Taking the total life cycle cost of fuel into account when purchasing a car, that's another story. Your 10 mpg will have burnt $60k of juice at 200k miles whereas the 20 mpg car will only burn $30k, but a 30 mpg economy sedan will take $20k of fuel in 200k miles and a prius at 40 mpg takes $15k.

Most Americans drive 15,000 mi/year

15,000/20 mpg * $4/gallon = $3000
15,000/25 mpg * $4/gallon = $2500
15,000/30 mpg * $4/gallon = $2000

Most Americans like to bitch about small things and ignore real issues as well.

LOL, it seems I had your answer 10 years ago on page 1. Gas was also more expensive back then.

Same subject which is why I bumped this thread, but again people were getting different answers.

And your paragraph page top doesn't take in to account what some people do, which is ditch a 10mpg truck for a 16mpg truck. Then you're really chasing your tail.
