How's your MPG?

My Audi gets ~18mpg city & 25+mpg highway on 93oct. I've quickly discovered that these 30 valve German V6s can easily become thirsty if right foot gets heavy. :icon_drive:

 

My '73 Satellite with a stock, tired, '77 440 would average 12-14 in the daily grind. MPG was directly affected by placement of right foot. I was too addicted to the TQ's wail when those secondaries opened up..........

bu....WAHHHHH!!!!

I had a 72 Newyorker 4-dr HT and a 75 T&C 440. You want to own shares in an oil company when you floor those beasts.

Good thing the seatbacks are firm, or my hands could have been ripped from the wheel, when my right foot hit GO!

 

The 442 gets a steady 13, and doesn't seem to care you baby it or floor it... 13 is its lucky number...

 

The easiest way to improve fuel economy - at least highway fuel economy is to slow down. If your vehicle is in proper tune, driving it at about 45 MPH will give you maximum FE. In general, if you have 4 speed automatic with a lock up torque converter, most cars will be in 4th lock up at about 45 MPH. Anyway, drive at the slowest speed you can drive in 4th lockup and you'll be quite impressed with your FE.

Question for you gear heads: If you have a 2009 Chevy Silverado 4 door 4 WD half ton pickup with 4 speed auto and drive it on a level interstate at 45 MPH, what do you think the average FE will be? Assume no headwind, no tailwind, and the engine is operating in cylinder deactivation (4 cylinder mode). I did it on a drive from Detroit to Nashville, and I know what I was able to achieve. (I also got strange looks for driving that slow from some impatient pendajos. Guess and I'll reveal the answer later

45mph? OK, if we ever do a road trip together, I'm Driving!

 

My 1990 colony park as been getting 17 to 21 mpg, as I recall from my last half dozen fillups. It matters a great deal whether I'm cruising on the highway, or stuck in stop and go/ stuck in city streets.
I haven't yet tested going 45mph on the highway... I'd get rearended by everyone else going 75, and goodbye wagon Boogie's probably right though. An engineer in the field would be appalled at this generalization: but I hear that, in general, 1500rpm is where you want to be. So if 45mph = 1500rpm (in 4th gear!), that would make good sense.

I had a friend (she was female, not to perpetuate stereotypes) who did not know what overdrive was, thought it sounded like a performance feature, and since she wanted a fuel efficient car she thought she'd leave it off!! She'd apparently been driving years with the overdrive turned off before I intervened and turned it on for her. I tried desperately to explain the idea --and the fact that her car had a tachometer should have made it an easier task-- but I'm not sure I succeeded.
I should ask her how her fuel economy has improved these past three months!

Modern cars really are much more efficient. Technology's going the right direction.

OK, so I drive for fuel economy. I hate headwinds by the way! Since no one seems interested in guessing what FE I got on my 4 WD, 4 Door Silverado on the drive from Detroit to Nashville- it was 29.7 miles per gallon. I think that is remarkable, but maybe thaT IS JUST ME.

 

1991 Subaru Loyale, selectable 4wd, 5-speed trans, 1.8 liter boxer four banger w/ 230K, I get a consistent average of 28 mpg.

Babying it, the best was 29.5 mpg, and when I run the A/C often it can often dip down to 27 mpg.

This is based mostly on my commute back and forth to work, mixed with occasional city driving on my days off.

My route to work is about 30 miles one way, mostly highway, but includes traversing a 2,300 foot elevation each way.

I'm looking forward to taking my wagon on a trip to my father's house, that route is mostly interstate and would be practically level travelling. I'm interested to see what kind of pure highway mpg figures I can squeeze out of my Subie.

 

Colony Park is pushing about 21 on the Highway.

 

There are some impressive fuel mileages here. However unhappy I am with 15 MPG with my Hemi Dodge quadcab I'd prefer driving with and above the flow. I don't get to stop and smell many roses but I get from here to there in the same week! By the way I have a feeling a certain friend's female friend was a blonde! I love blondes. My first wife was blonde. She's still my first wife!

 

I've been managing a consistent 21.5mpg during my daily driving through congested suburbia.

 

My OCC gets 19 mpg in mixed driving conditions.
