is there something out there to install on vehicles to get better gas mileage ?

Answer 1

Many devices have been built over the years. But guess what?

The oil companies buy the patents, and all prototypes, and never introduce them to the public.

Hmmmmmmmmm I wonder why.


In the 1980's there was a 1963 Lincoln Continental (Huge Boat) with a large V8 engine (exact displacement not known). Fitted with special device. It drove around the U.S. for a couple of months. It was later estimated that the Lincoln was getting:

Are you sitting down>>>>>>>>>>>>>>>>
125 mpg Highway
80 mpg City

So now you know why BIG OIL doesn't want you or me to have these little toys...........Less $$$$$ for them. Greedy S.O.B's

According to all the professionals there isn't anything that you can install extra on your vehicle to get better fuel mileage. You can do some things to get the best possible mileage.

Air pressure; keep your tires inflated properly, makes a BIG difference
Clean Filters; Keep clean air and other filters in your vehicle
Tune Up; Keep your vehicle where it can run the best.
Keep your vehicle suspension in alignment

The way you drive can make a very big difference in the fuel mileage. Try to keep an even speed, avoid jack rabbit starts. Drive as smooth as you can, why rush to a red light? If you lift off the gas and slow, then the light turns green you don't have to get that heavy machine moving again! Remember, that “car” is just a machine, and most weigh about 3,000 pounds, or more. The fewer times you have to get them moving from a stop, the less fuel you use.

Don't make unnecessary trips. Consolidate your trips so that you start your vehicle as few times as possible. You can wast a lot of gas driving around to save a dollar! Sometimes it is less expensive to pay a bit more for your needs than to use our expensive fuel to drive to several stores.

Yes, you can replace metal body panels with fiberglass or carbon fiber. Or remove any dead weight you're carrying around elsewhere. Lighter weight is one of the few changes that you can make that is almost certain to reduce your fuel consumption. Other than that, just keep the car well maintained, paying particular attention to tire pressure.

Trying to monkey with the engine's tuning to get better mileage is usually futile - many of the gadgets sold out there are either things built by well intentioned but relatively clueless inventors, or out and out swindles. Popular Mechanics recently tested a bevy of gadgets sold with the claim they'd improve mileage; results ranged from "did absolutely nothing" to "hurt gas mileage by 20%" to "caught on fire while testing."

Well, there are exceptions if you drive an older car. Swapping an old carbureted engine for a modern fuel injected one is likely to give you some more mileage and more performance.

Me, I've started trying to use a motorcycle instead of an SUV whenever possible.

In most automobiles, there are a few things you can do to improve mileage - replace cam bearings with higher-efficiency types, replace exhaust components for more efficiency, sometimes change intake components. You may also be able to replace transmission types.

However unless your car dates to the early 1970's or before, there isn't much you can do to alter the actual equipment on the car unless, as someone has already suggested, you swap out engines. I presume you don't want to be that drastic.

Cars are closely designed now with an integrated balance of components - ignition computer module, sensors, hardware, and all reflect your transmission, wheel sizes and types, and other factors. Whenever you change significant parts you will have to have these items adjusted or changed or the car won't work better.

People pitching things like magnets on the fuel lines, new high-mileage carburetors and other parts are trying to steal your money. They don't work and the people who swear they do are liars or thieves.

And by the way, most of the work you CAN do to change your car's equipment to very, very slighty improve mileage costs so much you should question whether it's worth the price.

Now - the PRACTICAL ways to improve mileage are to ensure your car is well-tuned, filters clean and replaced often, tires inflated properly, and that you used good driving habits to maximize mileage without also becoming a roaring nuisance on the roads.

Answer 5

The best overall is a good tuneup. Most of the "add-ons" never live up to their claims. Also a gentle driving style will increase overall mileage. Some of the products that go in your air cleaner or intake hose create a veturi effect and do offer improoved mileage but even this is very minimal. In addition to a tune-up, make sure your air filter is clean.

Answer 6

A tuneup.

There are no "magic" fuel saving devices. The US EPA tests various devices advertised to save fuel and posts the results on their website. The very few that actually save any fuel are being incorporated into new vehicles already, such as the switch that cuts out the AC compressor under hard acceleration.

Answer 7

The only real solution is to buy next car more economical with smaller engine. There are plenty of gas-saving gadgets advertised, but if any would really work all car manufacturers would already use it.

Answer 8

If the car runs at operating temperature, and is running good, there is nothing you can do, except drive slower, avoid racing in lower gears.. Everything that is said to save fuel that you can buy, won't.

Answer 9

Yes.. find a parking place for it..stop using vehicles as toys..if you just need to ride..get a bicycle... personally I have found that about 25% of my trips were needless. ..and yes I have a bike now...:)
