Saving gas

I have a '93 Cadillac De Ville, I love the ride, my wife has fibromyalgia so the big size and leather seats make it easier for her to ride, but I average about 17 mpg in town and 20 on the road, any ideas how to improve this? PS I hate the electronic gas gauge since it focuses my attention on the number of gallons and their reduction as I drive- any ideas?

There’s not much you can do besides making sure the tires are fully inflated and the car is in good tune, except for driving very smoothly, gentle on the gas and brakes.

Ditto. Whatever you do, though, do NOT fall for any of those stupid, gimmicky devices that promise improved fuel economy. It’s a waste of money and you’d be better off filling your tank with the money you would be spending on them.

Sorry about your gas gauge. There’s not really anything you can do about it. Cadillac apparently thought this feature would make the car look smarter or something. I don’t know anybody who actually likes that feature.

Cadillac De-Ville V8 NorthStar. “Saving Gas”. Get serious.

Enjoy the Cadillac and don’t worry about the mileage. You would probably spend more on remedies that probably won’t significantly improve the mileage than you would in buying the gasoline.

I have a minivan and and SUV–a Toyota Sienna and a Toyota 4Runner. These cars do about 23 on the road and 17-18 around town. Both are comfortable for us with the high seats. At my age, I’m not going to drive something that is uncomfortable just for good gasoline mileage.

I have to agree. Pushing a big car through the air takes a lot of power and a lot of power means increased fuel consumption. Simple matter of physics. The advice for keeping your tires inflated is right on the money.
