Re: worse gas milage

Well, it wasn't a car, but I bought a used 24' GMC box truck from Uhaul to move from California to Minnesota. When loaded, its weight was 17,600 lb., just 400 short of its max GVW.

With a truck version of the Big Block and a 5 speed transmission, it averaged 6 mpg for the 2400 miles. Rarely did my speed exceed 55 mph, and a heckuva lot of times I was in 4th gear doing 40-45 up some hill.

By the way, it is most certainly uphill all the way from California to Minnesota.

The day I left, with my wife driving a Lumina APV, the air conditioner quit. It was 105 degrees in Needles, CA when we quit for the day, and I had to run the freaking truck's heater to keep it from overheating. Nothing to be done with the air conditioner. The compressor had seized up. I solved the overheating problem by removing the condenser from in front of the radiator, but never did solve the mileage problem.

Fortunately, gas was only about $2.50/gal back then, so it only cost about $900 for the trip. I got here, and sold the truck for what I paid Uhaul for it, so it all worked out pretty well.

For me it was the 1957 Willies jeep.A six cylinder flat head.I did not drive it much because we mostly used it to provide electricity (220 volts) through its generator.

85 cadillac sedan deville gutless v8 never topped 13-14 for me.

My 04' company taurus struggled to top 20 and it was almost always highway driven.

My engine swapped 400+ rwhp 240sx cruises at very high 20s low 30s on the highway. I may move to a taller rear to improve that a bit more.

My 18hp twin cylinder Sears tractor gets about 1 -2 gallons per mile, especially in low gear with the mower deck running.

Boats of course get the lowest mpg of about any vehicle. You can tell if a person has any basic knowledge of mechanics etc by asking them why. I know why who here does not?
