Hmm... interestingly my DD has been down for a week and I had been DD the Swift. 2 tanks I got 35.5 and 36.1mpg back to back. Not bad for the way I drive.

Turbo'd 94 GT flogged daily, averages 34-36 mpg with mobil 1 synthetic in the engine and GM syncromesh in the trans. On long trips has done over 40 mpg.

I track my mileage every tank, and since the switch to synthetic it jumped a consistent 2-3 mpg. That and I don't change it as often (7-10k miles) I'm never going back to standard oil......

Anyone who's been around children will tell you that they are in fact quite stupid. Many of them cannot even read.

1987 Chevrolet Sprint turbo
189,xxx miles
Car is stock with pre-cat removed and tires/wheels upgraded to 185/60R14. Per, this should be a 7.8% difference in speedometer/odometer readings, making my recorded MPG 7.8% lower than reality. However, my wife paced me with her car and said my speedo is dead on so I'm not sure what's what.

39.2 MPG from Seattle to Vernonia - mostly highway with a few hills at 60--65 MPH.
Last 4 tanks commuting 60-65MPH (~3 miles city, the remaining 32 miles each way are split evenly between 4 lane highway and 2 lane mountain highway:

1987 Sprint turbo
1989 Dodge Caravan SE turbo 5 speed

1988 Chevy Sprint Metro. (Sprint ER by any other name) Original cam and transmission. (3.79:1 final drive)

Driven carefully at 65mph, without too many hills, and with no substantial wind: 52 mpg (The OKC - Dallas run on I-35 is my usual test.)

Same conditions at 55 mph: 60.4 (But I've only tried that once.)

In general, I find that each extra mph costs me about 0.7 - 0.8 mpg, in that speed range. At 75, a don't expect more than about 44 or 45 mpg. But I'm less certain about that because I just don't drive it that fast very often. I don't really like pushing it past 3000 rpm, and that falls at 68mph for this car. Of course, my 92 Geo Metro automatic hits 3000 at 45mph. But I don't really like that car, so I don't care. :wink: I've run that one at 75 mph with a shop tach connected, wires run around the driver's door frame. 5000 rpm, if you can believe it. Those 3 spd, non-overdrive, automatics without even a locking torque converter were like something straight out of the '70s!

Edit: I should mention that the tires are P155/80-R12 and I generally keep them at at 35psi. (Sometimes 32psi) Everything is pretty much stock. Except that we went with the "regular" 3 ring pistons, rather than the 2-ring, during the last rebuild. And any possible difference has not been detectable.

I would suggest that the more pertinent details one can give in this thread, the more helpful the numbers will be to other members. :)

haha bad to quote myself but my figures were wrong and iw ant to clear it up. i now get 14.5-15km/l which i believe is 55km/usGal which is 32.3MPG. I forgot to reduce km to miles.

While fe isnt my ultimate goal, i like to keep track of my FE as it usually is a good representation of how my engine is going and how dire a service is. Always use Mobil1 suspersyn products.
