What kind of fuel mileage do you get?

[JIPJOBXX]

I myself think that I might get 14 mpg in town and maybe on the open road 15 or 16. I have a fairly new engine 218 with a fluid drive. I'm sure that the fluid drive really eats up the gas as it is not very efficient. What do you get?

[47heaven]

After doing some calulations I figured that my P15 gets 15-17 mpg. Is there any way to make them get better gas miliage or is that the best it gets on these things? At least it's better than what a SUV gets, I heard.

[Normspeed]

I might squeeze 16 -17 out of mine, using a lot of OD, a lot of open road and with a light foot. I think I'm more likely to get 14 or so most of the time. That's with 2 B&B's and the 4.10 rear.

[BobT-47P15]

I think mine with no modifications, other than the .30 over re-bore, only

gets 14 or 15.

I thought it was doing around 17 until I checked it against

a more accurate odometer (in the wife's PT Cruiser) when going to Tulsa

last summer. Found out my odometer is off---therefore my mpg was less.

[Uncle-Pekka]

I have not really measured, but roughly my D24 takes 15liters/100kms on the road, which is 15-16mpg.

I am quite satisfied with that number, taking in account, that I have not done anything but adjusted the timing for the engine.

It lets out a cloud of white smoke in every cold start and the oil pressure is low even if I run SAE40 thick oil in the sump, thus I know at least piston rings and main bearings are worn.

P.S. -off the topic - (don't throw me off the forum)

My 1998 Renault Scenic RT does 32mpg in same conditions. Scenic is a family car what you could call a small minivan, it has 2.0 liter four cyl. injected engine, actually very nice car to drive and have... Much better to japanese rivals in my opinion.

I've had it for six years now -I open the hood once a year to change the oil. Nothing fancy but does the job.

My 1940 Dodge Sedan with the single 4 barrel Holley 318 Poly/cast iron auto and 3.23 gears got 21/22 mpg yrs ago on a long trip, it included some long flat stretches and late night/early evening cool temp driving.........but as these are as aerodynamic as housebricks my normal driving of the sedan would be 15-18mpg, as for the 41 Plymouth Coupe which has the original 6, I'd be happy with anything over 15 mpg also........andyd

Hi all!

I get the same as Uncle Pekka on my 52 Kingsway with campingtrailer beheind(1100 kg) and about 13,8 liters pr 100 km on normally driving.

[james curl]

I did a 4600 mile trip last summer and averaged just less than 14 mpg. Most of the driving was in the 60-75 mph range. Around town it verys from 10 to 12 mpg. I have duel carbs, .040 overbore, a mild cam, duel exhaust and a .090 milled head. I trully expected better gas milage as I changed the 3.9:1 rear for a 90 Dakota 3.55:1 rear before the trip.

[TodFitch]

14 to 17 MPG for my 1933 depending on the what kind of driving. Spot checks only for mileage on the 1933 unlike the 2004 Prius which I have kept compulsive records on since new (44.82 MPG total miles/total gallons).

[claybill]

miles per gallon vs liters per hundred...

in europe they compute mileage differently....by how many liters per 100 kilometers....here we go by miles per gallon...

i wonder which is best or more accurate..???

[JIPJOBXX]

I have an add that states the new 1942 Dodge will get 21 mpg boy they even lied back then didn't they. I will try to find that add as the car they show doing this has no body but just a frame and whatever was needed to drive it.

[Norm's Coupe]

When someone ask me how many MPG's I get in my coupe I always tell them. "About that much". Have no idea how many and don't care. Bottom line is. It takes me as much gas as it burns to get from point A to point B.

[Young Ed]

Norm didn't we decide yours was figured in DLPG(driveway lengths per gallon) or something like that?

On the fall trip we took last year I got 19.8MPG over 600 miles of driving. Along the trip I was checking my odometer by using the XX miles to the next town. Was always right on or within a mile.

Ed, can't count driveway mileage. If you pull forward in the driveway, then back up the same distance, your mileage will be the same as when you started. You'd have to figure "Hours per gallon". Don't keep track of that either.

[Powerhouse]

well, i don't recall what i got before the OD and 2bbl prog carb and 1957 dizzy with dual point kit and 3.9.1 rear...but now i get about....double of what I did before. If i use the OD that is. I have it written down at home...i'll post later...if i remember.

[blueskies]

My '50 with a hopped up 230 has dual holley/webbers, 3/4 cam, 9:1 compression head, HEI, tube headers, '55 Dodge overdrive, and 3.9:1 rear.

I get about 19 on the highway, and 14-16 zipping around town.

I have checked my odometer with a handheld GPS, and it is right on, so I believe the milage calcs are reasonably accurate.

Maybe the guys here should take up a collection to buy Norm an hour meter like on a tractor.

[greg g]

Our trip to Detroit comprised 1035 miles. This included 2 1 hour + idle sessions at the US Cananda border, and about 160 miles of runing around the Detroit area. Consumed 54.6 gallons of fuel and 1 qt of oil.

Dual carters on a 230 with 50 off, 30 over, stock cam and 3 speed 4.11 with 225 75r 15 rear tires,

[Dennis Hemingway]

I get about 16 mpg on my 48 P15.

At least it's better than what a SUV gets, I heard.

I get 21 to 23 mpg in our 2001 Yukon SUV and we got18 mpg while towing the P15 up to Big Bear Lake.

I might have one. I will have to look.

Detroit and Back in my 49 Midget p17, 21-22 in my 49 George Asche supplied , carbs, trans, w OD, 70 off the head, stock pistons and cam. 4.10 gears 65-ish on the highway

[Johnny S]

I suspect the math will work out the same in either measurement system if the numbers used in either calculation are accurate. Then you simply have a conversion table.

As to Norm's fuel consumption based on following the threads over the last several years on this topic I suspect an hour meter would be a good metric to use. And I do like the idea of "driveway lengths per gallon".....or "liters per driveway length" for those of you compelled to use the metric system. But, one measurement that hasn't been discussed is "gallons (or liters) evaporated per month". That might even out the playing field for all of us.

[BloodyKnuckles]

After reading through everyones response I'm almost embarrassed to share my MPGs.

When I did my 5000+ round trip to Vegas from Charlotte, NC we checked numerous times and we came up with 26 MPG. My car has a tired old engine that knocks, leaks oil, a '54 OD from Asche, stock rearend, 500lbs of tools and parts, 400 lbs of men, 150lbs of luggage and guitars.

We checked numerous times and sometimes it was better and sometimes it was worse but I am sure it gets great mileage.

BloodyKnuckles

[Normspeed]

BK, with the 400 lbs of men, do you think the methane-rich environment could have been a contributing factor?

I think you must have used a gasolene extender to get mileage numbers like that. I have heard that adding paint remover to gas does wonders:eek:
