CB7 Auto Gas Milage Numbers - Post Up!

Last few months I've been watching my gas mileage like a hawk. I've been averaging 24-26 MPG. Driving is a combination of freeway, city, and rural.
Out on the highway I drive conservatively, city the same, out in the rural areas I'm a bit more heavy footed.

I switched to premium (90 octane) gas for the last few tanks and I've been getting better MPGs (26-27) all the time regardless of my driving style.

Just out of curiosity, what are the other CB7 autos getting for MPGs?

Now that the fuel leak is fixed...

24mpg, 90% highway driving A/C on @ 80mph.

93 LX sedan

DC header
Magnaflow catalytic converter
Yonaka catback
E15

Corn free gasoline is $1.00 more a gallon here in Iowa.



\/ No problem Jon. I'll add my specs as well.

My son has been consistently squeezing 30 mpg out of my stock 93 LX wagon in mostly highway driving this summer. My 92 EX coupe does about 26 in mostly city driving, low 30s on the highway.

I'm getting 300-330 miles a tank... I do drive mostly city, and I'm not a light-footed driver..

How much is a full tank though? 16 Gallons right?

The owner's manual indicates 17 gallons, but the one time I ran out (on the way to get gas) it would only take 15.3 gallons. To actually check your mileage, keep a log of miles driven and fuel used. I don't usually let them go long enough to let the light come on, but that would normally result in putting in about 14 gallons.

Miles driven ų gallons previously put in your tank = MPGs

Keep that logged over a few tanks, weeks, months, years... and you'll get a good record.

I typically fill up with 12 gallons, don't want to be stranded out in the middle of Nowhere Idaho.

The most I ever put in one was 14.3 gallons as I recall. And I was running out going down hills on the way to the gas station. That was many years ago.

Turns out I'm getting 22MPG! Not bad considering most of my driving is stop and go, and with WOT runs inbetween.

22 aint bad at all actually.

What was strange was that the first few years I owned mine I was getting 22-23. I then started doing routine maintenance, cleaned out the intake system, EGR, all that. Started to get 24 regularly (all stock at that time too).

I just assume the car gets 20 to the gallon, it'll surprise me and usually putts around on E for a good while when I need it to so maybe 22 mpg. I'm waiting to get a new fuel filter, then I'll add some Marvel to my gas to clean her out a bit and see what happens.

A6, gutted OEM airbox, OEM header and downpipe, no cat straight piped to the rear wheel where it dumps, crankcase inlet vented to atmosphere, other stuff I think I'm forgetting. Heavy foot on the interstate.

Gonna throw her on a scale soon and see what she weighs with a full size spare and a carbon fiber hood.

That's funny Gabe, I get 350-400 city/highway. I'm surprised you get less than I do.
