That's my 93. I had almost a year worth of data but my phone screwed up and I lost all my data. That's only about four fills worth of data.
I don't exactly take it light on her, and like I said it's all city driving.
It's almost always between 15-17. I've hit 18 a few times but I don't count on that.

Best upgrade for better mileage is to buy a Honda, and enjoy driving your Mark they way they were ment to be driven.

Sorry Sapp, not reading instant mpg. Reset my mpg 2 months ago, and right now it's on 23.7 (not instant), 50/50 driving. This car get's better gas mileage then anything I have. With the exception of the bike. I've ran the numbers, I'm not lie'n!
If some of you are getting 12 or 14 mpg's then there's something definitely wrong with your car! I get 350 miles on 3/4 tank of gas and that's not a lie either! I don't run it any lower then 1/4 tank.
If you let the mpg keep rolling for 2 months without reseting it...how's that instant? I believe that's called average.

no sir. you get better mileage with the car in gear because of the fuel injector cut off while coasting.
the car can't turn the fuel injectors off in neutral, the car will stall.

So you get less mpgs with a 50/50 mix than you do all city driving?
I don't think any amount of explaining will make any of us believe you get that type of mileage on 87.

I couldn't sleep at night, knowing that I put 87 in one of my cars. Last time I filled my PU ( I feed it 91) I hit the 93 button from habit. Did'nt hurt at all.

Not sure what your getting at Low? What I'm saying is I get 24 mpg (average) over a period of 2 months on the cheapest gas 50/50 driving, city/highway everyday driving. If I do straight highway driving (70 mph, cruise set) I get 30+ mpg (average) easy, on the cheapest gas on a 350 mile drive.
The car says premium recommended! That means you don't need it...it's only recommended! My car does fine on the cheap stuff so why waste the money. No pings, no knocks and at 210k I must be doing something right. When I do get in the gas pedal it's all Mark VIII. When I let it warm up for 15 minutes during the winter I still get no lower then 20 mpg.
I can't have the only Mark that get's good gas mileage. You mean no one else get's 24/30 out of there Mark? I find that hard to believe.

"Around town 24 easy." would be city driving in my book. That's what you said the first go around which made me raise the :bsflag:. 30mpg on the highway would be believable with a nice wind from the backside. But again, on 87 I don't see that happening.

When my car is a spit away from full it'll read 300 miles to empty.. How you're getting 350 on 3/4 is some kind of mystery
I get 24-25 on the highway at 75+ mph. 18-20 in city. Maybe if I cruise at 60 mph the whole way I will get 30 mpg but that is way to boring for me. So ya, it is hard to believe you getting 24 in city alone.

Oh brother!....24 city/highway, 30+ straight highway. What is so hard to understand about that? Have I had the wind in my back for the last 15 years coasting down hill in neutral reading an instant mpg gage I don't even have?. I'll tell ya what...I'll fill it this weekend and take a frick'n pic!
Sapp, if you fill your car and only get 300 miles to empty, you better take it apart and try again.
You and Low both have gen 2's right....that must be the problem. I've never owned a gen 2 so maybe the problem lie's there.
But I'll still take the pic because I must have the only Mark that run's good and far on cheap gas..
I drive this thing 350 miles one way all the time and get there with a 1/4 tank left but...it must be my imagination huh?

I have a Gen2 (with a Gen1 hindsection, to include its lack of EVAP purge canister/solenoid/tray) with 86,000 on the clock. For the past 4 months I haven't reset the AVG FUEL ECON button and so far it is returning 22.6-22.7mpg. That is with a mix of 50% 'City' (below 60mph with frequent start/stops), 40% Highway (80mph+), and 10% with my foot to the floor.
The only mods to the car so far have been a Jmod and a K&N filter. On the move from Ohio to Florida, with the girlfriend driving the car (65mph average), she got 26mpg on the highway. I really should take the time to replace the plugs and coils, clean the IAC and intake tract, and check TPS.
All of this has been on Mid-Grade fuel quality.

Spree.. If you're getting 30+ mpg on the freeway.. You'd be the only one ever in a MarkVIII to get that kind of milage. My car will never see that because I have 3:73s

So far the best I've ever gotten was 29mpg average driving from Candor NC to Myrtle Beach SC and back in 2001 when I first got my '96 with 60k miles on it. The '97 LSC was lucky to get 20 and the '95 averages around 22 +/-. I'd like to see it get better mileage, but I have a short drive to work and back now so it's not going to be as good. And I only run premium in my car.

My car is getting roughly the same mileage as your getting.

Who needs a 2.2l 4cyl Cavalier for good gas mileage when you can just buy a 4.6l V8 in a car that weighs a couple thousand more pounds and gets the same?
Spree
Dedicated LVC Member
hhmmm...29 in a gen1 and 20 in a gen2. Weird...could there be that much difference between a gen1 and gen2? I wonder....when you fill up or anyone fill's up, how many miles to empty does it say? Is this accurate....no...just wondering.
Sapp's car only say's 300 miles to empty when it's "a spit away from full". Mine is much more.
Lownslowlsc

I think the total miles to empty take the current mpg as the calculator. I could be wrong.
I just filled up so I'll go check...
....348 miles to empty @ 18.3 mpg. Actual mpg is 18.5 and creeping up due to the summer blend and my somewhat recent switch from 89 to 91+, it usually levels out at 18.9-19.1 for my daily commute. That's 95% "City" (<45mph) driving. There is a 2 mile stretch where it's 55mph on my commute to/from work.

I will fill up tomorrow and take a pic. Wife is gone today and has the camera. But i believe it's around 450.

Curious, what's your definition of "city" driving? You live in a pretty rural area where I'd image the traffic is very light with a lot of open road. That might not mean "Highway" to you, but it very well could be based on your definition of each.
Spree
Dedicated LVC Member
My definition of city driving for me is...I live in a small town so it's 45 mph or less 3 or 4 stop lights and a 55mph gap for 5 or so miles until another small town comes up with maybe 1 or 2 more stop lights. I don't live in a big city like New York. Small town I guess you can say, but city to me, (maybe I should have said town) but still 24 average. The open road, hwy 70 at 70 mph with cruise set still averages 30+, more like 32. I do drive to Indianapolis a lot but stick to the 55mph area most of the time. I'm not saying I get 24/30 all the time. That's just my average. Some more, some less, but I don't have an instant gage in the Mark that I know of.
If i drive from Ohio border to St Louis (350 miles). I make it there with a 1/4 tank left. My other cars won't do that.
I have 3 vehicles with an 18 gallon tank. This Mark will go twice as far as they will and only runs at 1800 rpm's in OD at 70. Maybe that has something to do with it.
Some of the things you guy's say your cars do or act like doesn't make sense to me because that doesn't sound like mine at all. I've had this for 15 years and I know how many mpg it get's, how far it will go on a full tank and what the display says, how fast it will go, how it corners, how fast it will stop, what it smells like, feels like and so on.

Filled up just for you Sapp. The question is will it get 464 miles out of this tank of gas? Probably not! But straight hwy driving....hhmmm....maybe. I KNOW I can get 350 miles on 3/4 tank, I've done it many times. How many more miles are left in that 1/4 tank? I'll never know because I don't drive it less then 100 miles to empty. Have a good day!....

City/town, call it what you like.
From what you describe it sounds like a lot of open road to get those mpg's up and imho would be closer to 75/25 . Take it to a more urban area (What i'd consider "City" miles) and you'll see your fuel consumption get back to the epa spec. Your high avg via the onboard computer def reflects on the miles till empty. Not sure if instant was available on all years but try hitting the fuel buttons a couple extra times to see if it pops up.

Economy is MPG (not instant). Status is gallons left. Range is the pic above. There is a lot of open road that's a fact and there is a lot of towns between here and there. Maybe I'm wrong but 50% driving around "town" (city) and 50% highway (55 to 70) to me is 50/50, am I looking at it wrong? Either way I'm getting 24/30+ everyday for the last 15 years....lol...
