Will magnets on my fuel line increase the MPG of my car?

Question

There is a company that claims it will.

Answer 1

No but losing excess weight will!

Answer 2

Could it possibly be Eco-flow?

We tried these magnets at our local technical college on a test bench mounted engine to see what effect was obtained.

1, The first problem was that all of the fuel pipes are steel or steel reinforced flexible pipes, nullifying the magnetic effect.

2. After changing the fuel pipe for a nylon type (illegal for use on road vehicles) the engine was run at a constant speed at maximum torque on a water brake dynamometer for 8 hours continuously without the magnets fitted, and a base line fuel consumption figure was obtained.

3. The magnets were then fitted and the test repeated with the same parameters, and fuel monitoring using digital metering.

4. The overall test resulted in a base fuel consumption of 6.6381 ltrs/hour, as compared to a figure of 6.6294 ltrs/ hour magnets fitted.

5. The overall reduction in fuel consumption was 0.0087 Ltrs/hr, representing a cost saving @ 96p/ltr, of 0.0084 of a penny.

6. Subsequent tests using the common urban cycle actually showed an increase in fuel consumption albeit minor.

7. Recommendation - don't bother.

Answer 3

The correct answer is no. The claims of increased MPG, etc. are junk science that's made up by the company that's trying to sell you their special magnet system. Infomercial-type junk like this is merely designed to help part you from your money. It's similar to those little gizmos you put in your air intake that are supposed to increase MPG and horsepower... they don't work, at least not nearly as well as claimed, but you can't really conclusively prove that they aren't working, and they MIGHT work. Thus, these guys skate around fraud laws.

The best way to maximize your MPG is to keep your vehicle properly tuned, your tires properly inflated, and to change fluids and filters (including the air filter) at recommended intervals....and to practice good fuel-saving habits such as not letting your car sit idling too long in the driveway, avoiding jackrabbit starts from stoplights, and driving in the highest practical gear (i.e. using overdrive on the highway, unless towing something). Also add the occasional bottle of fuel injector cleaner every 4-5 tankfuls of gas to help maintain a clean fuel delivery system.

Hope this helped.

Answer 4

Its complete and utter b*llocks.

Go down the scrap yard and extract the permanent magnets from a electric fuel pump and put em over yer fuel line if you must. It'll cost you a lot less. This rubbish rears its ugly head every few years as does lead pellets in yer tank or fuel lines.

I was an engine experimental fitter and have seen tested this psuedo scientific nonsense and seen no effect at all ever ever ever . Its just that no trading standards dept will pay mega bucks to prove these ex double glazing salesmen wrong.

The same goes for oil additives and flushes - its just capitalism.

Magnets can have a benificial effect in picking up lost nuts and on domestic water pipes.

Answer 5

Not at all, they are a con.
how could magnets increase mpg?
all the fuel is not able to be affected by magnatism in any way, It's just liquid going down a pipe.
Watch out It's a scam.

Answer 6

My dad purchased a thing like this few years ago from a company and was reluctant that it would do anything. He drove a BMW 735i which has an on-board comp telling things like MPG etc. Surprisingly it did actually increase it by about 1.5-2 mpg. I cannot remember how it was supposed to work, but it definitely did something. Unfortunately he left it on when he sold it, otherwise I'd have it on my car now! :(

Answer 7

Myth busters should do a show on cow magnets and fuel ionizers magnets for extra fuel mileage. It is because you are driving more smoothly and not flooring it on take off. OH YES the quick fifty! $50 dollars for magnets changes hands quickly.

Answer 8

alledgedly...


look I saw this thing a few years ago that chinese fishermen discovered that about 80 years ago they put a magnet on the diesel fuel line to the engine in their fishing boat and it went further per tank full of fuel... there is so much abou this I have no idea if it works or not... I can tell you that it does affect water in Kent they have really hard water and it stops the hard build up of calcium in the kettle and makes it softer so easier to clean off...

Answer 9

Theres something that you can buy but when you look at it the difference is negligable and you spend quite a bit getting it fitted, just slow down a bit and use your gears correctly and you will save more fuel and money this way!

Answer 10

no it wont,,all these gimmick,s you hear about,,are just that gimmicks,,none of them have proven to work,,before you ever invest in anything like this,,take a minute,,and think about it,,if any of this stuff really worked,the new cars would have it on them,,because that would make there cars get better mileage,,i own a repair shop,and you wouldn't believe some of the questions i have heard form my customer,s,,but ,,we all want more mileage from our vehicles,,maybe some day someone will come up with something that does really work,,good luck,,i hope this help,s.

Answer 11

I saw a special on TV that said that was fake. It actually increases MPG and can damage your computers.
It is a rip-off.
SLOW DOWN< use correct tire pressure, and don't GUN your engine--boring but will save money.
