Sure, but the difference I've measured between cruise control and not using it was far greater than 2 mpg. And the point is not the 2 mpg difference, but the realization that it all adds up.Here is my calculation, based on the difference between 40 and 42 miles per gallon over 1 million lifetime miles, fuel cost of $3/gallon, and driving from age 16 to age 81 (roughly 15,000 miles per year):
$3,571 = lifetime savings
$55 = savings per year
Others may make different assumptions or drive more miles. For me, the difference is negligible. YMMV, so to speak.
I bought the car in Des Moines, Iowa. I live in Omaha. Roughly 2 hours @ 138 miles. On my way home from the dealer I got 36 mpg using cruise control. I've made a few other trips to various places and to Des Moines again. All of which without using cruise, I've gotten anywhere from 42 - 48 mpg. Using your math, and sticking to the 1 million mile mark, I would save anywhere between just shy of $12,000 or all the way up to $20,833.... (of course this will vary over one's life as you're not getting the lowest of these marks 100% of the time or the highest of the marks 100%)
That's a lot of parts I could buy.
