Ok, I'm curious, who gets the best gas mileage out of their classic mustang? Please post your MPG (if you know it, approximately) and your Year/Model/Engine/Tranny/Rear Gear Ratio.

I'm way curious over here.

We ran the car to LA and back twice. 351C, toploader, 3.50 gears. We got
14mph average. We burn 5 gal. in 10 laps at Laguna Seca. That's about
4.46 per gal. BUT IT'S A LOT MORE FUN!!!!!

Best- original/unrestored 65 convertible, A code, 4 speed, 3.25 = 24 mpg

Worst - 68 coupe - 429, automatic, 5.30 gears

This car ended up being sold backl to Ford in the mid 80's as a give-away car for one of their promotions

My 1966 Mustang Coupe, stone-stock 289-2V, C-4, 2.80 axle and single exhaust averaged 14mpg when I got it. Adding a set of dual exhaust glasspaks instantly raised it to 17mpg. This same car, at 70mph, with the AC on and two people in the car, would get 20-21mpg on the highway.

65 stock 289 K fastback 3:50, 4speed. 11-12 town, 16 mpg freeway at 70 mph.

65 convert. 302, Holley 600. Auto, 3:20. 10-11 town. 17 freeway at 60-65.

I'm confidant with exhaust gas analyzer/dyno tuning at least 5 mpg or more could be added to both of them at freeway speeds.

Slightly warmed over '66 289 +0.030 Coupe, std C4, stock single exhaust, 3.25:1 rear (posi). About 16mpg all-around driving (commuting to/from work, 20 mile each way, most of that on freeway).

Much better than SWMBO's '96 454 Suburban - 12 mpg highway!!

I fully expect a dyno tune to help, since I've never figured out how to tune the secondaries properly on my Edelbrock 1406 carb (I can see small amounts of smoke when I stomp on it). Am also glad to know dual exhausts help the mpg. Decided not to switch to AOD tranny.

Thanks,

65 fb, 289, Performer, Holley, Tri-ys, Turbos, C-4, 2.80 gears = 18 mpg doing a 35%city/65%higway drive.....52 miles round trip. I will let you know my highway mileage when I get back from North Myrtle Beach in June...

[Guest]

15 city 22 highway
289 2V stock everything exept Petronix installed.

Can anyone tell me how to make it better? I recently rebuilt the carb, changed cap, rotor, wires. Plugs look new. 73K original miles.

Before all of that I was getting around 12 so I was happy until reading here that I can do better.

There's still a slight miss at idle but besides that the car runs great. What's the next phase of things i should be looking at to bump it up a couple more MPGs?
