Miles Per Gallon

[louieglen]

What is the average MPG on the Model A's?

[Kurt in NJ]

When I kept record I got 23 mpg at 55+mph over 1500 mile trip
Locally it gets 20 with mixed parade and regular driving--10$=about 100 miles

[Curtis in MA]

I've never gotten more than 17.

[Big hammer]

Pull your plugs and if you see a tan color your good to go! After about 1 1/2 hours of driving Iam ready for a pit stop, driving in any car.

[Gold Digger]

It sounds unbelievable but I got 24.4 once on a tour. I had just tuned it up and drove 45 to 50. Never got that before or after.

Not me
I’ve tried different carburetors and plugs never got over 18 mpg.

[holdover]

15-20 depending on how many hills, always drive below 50 MPH

[fundytides]

Back in the day, a guy in our area used an A as his everyday, go to work, driver. It was in decent shape but well used and he averaged 25 miles to the Imperial gallon which equates to about 20 miles to the US gallon. A little less in the winter.

[BillEbob]

18 is about average for my Vicky, but then again we’re about a mile high here.

[Synchro909]

I won our club's economy run a few years back with nearly 31 mpg.
Before you start saying "That's BS", we used to use the Imperial gallon.
I think that converts to about 25, maybe a little less to the US gallon.

My 1931 Victoria gets about 15 in the city and about 18 on the (non-Interstate) highway.

Depends on terrain and weather, but mostly around 18 mpg.

[Sunnybrook Farm]

There was an article in the Restorer magazine probably in the 70s that showed a Ford report on mpg back in 1931 I think. Anyway it matches what people above are saying with most in the upper teens as I remember. Some were higher and some real low (probably leaking carb) anyway if you get in the low 20s then you are doing things right, just don't lean out and burn the valves. Of course we drive differently now, the state wide speed limit in Virginia back in 28 was 35 MPH unless other wise posted plus our engines are bored out and things have been done to get a little more speed.

[ryanheacox]

If you get high teens-low 20s you should be good. I can do almost 20 in my Fordor on hilly roads. Not bad for the heaviest Model A they made.

[30 Closed Cab PU]

I only get about 14 mpg max. Not sure why. Odometer calibrated, Fresh motor, tried different carbs including a rebuilt Berts, spark plug reads good, 3.54 rear end. 16 inch tires. Since it runs perfect, am living with it.

[Kurt in NJ]

The first rebuild of my engine when I first restored the car only got 15 mpg, only went 52 mph, when the rear main crumbled at 3000 miles I replaced the sunken valve seats, and replaced worn original cam with a "B"cam that showed little wear, ---same distributor,carburetor, manifolds , rods, pistons head, etc,--- made all the difference, top speed went to 67,fuel mileage went over 20

[barkleydave]

18mpg

[Synchro909]

Another factor that influences economy which is not mentioned so far is gearing. My '28 Tudor has a 3.54 diff and Mitchell 26% O/D and B engine. The end result is not good. It is comfortable at 60 mph but even if I see an incline on the horizon, it slows down. Because the motor is lugging in O/D, it guzzles fuel. I have had it as low as 13 mpg - that is not much more than 10 miles per US gallon. I'm on the lookout for a standard gear set (3.78:1)

[Peyton]

Over the past year 12.5 to 15.5 mpg. Car runs very well and is stock with no o/d. Drive 45 to 50 on tours. Engine is .100 overbore and operates in normal heat range.

[Bill G]

I get about 15, and sometimes 17, but no higher.

[Jim Brierley]

Syncro99, I would recommend a 4.11 R&P, with your 16% OD, it should do very well.

[1931 flamingo]

I never checked the mileage, no need to. When it got down to a 1/4 tank I would just put 10-15$ in it. Same with my "new" 40 with dual 97"s, just put more (a lot more ) in.
Paul in CT It's only money to have fun with.

[barnstuf]

My Coupe with 3.78 rear end and a Tillotson F1 B carburetor consistently delivered 25 to 26 mpg on 100 mile trips I regularly made. That all changed when I upgraded the cars appearance with paint and upholstery and decided to install a Zenith carburetor. No other mechanical change made but my gas mileage dropped to 19-20 mpg.

Jim, I've never spoken to anybody with a 4.11 rear end but my other cars do well with a 3.78 ratio and the 26% O/D (I assume your 16% is a typo). My motors are not standard except this B engine which should put out 50hp anyway. I realise a new CW&P is in my future but they are oh so very expensive.

Did you notice a difference in power.?

Haha, I agree! I would add the top speed of his Model A.

[SAJ]

I get 24 mpg on tours at about 55 mph on imperial gallons. 26 % overdrive B carb on bored A manifold, radial 18 inch tyres, standard roadster.
Round town this drops to 17 to 18 mpg. Plugs run a very light tan colour on tours.

That is just not true.

I get 98 miles to the gallon and just had sex for the 9th time in 30 minutes. My 18 year old wife just cant keep up with me.

LUCKY YOU !! ! Does she have a sister??
