Anyone used Motoflow magnetic fuel conditioner?

[Eklipze3k]

Ahh bugger, missed out the =uk bit, at least it works now

Here are some pictures from by 1998 Brava SX with those magnets on the fuel line. A total of four magnets are installed.
Will post some pics from my 2004 Punto Mk2 1.2 8v later on.

 

[ChrisUK]

That's ridiculous.

 

[dronenrs]

i'd be concerned of the effects on the alternator... being that close considering it relies on a magnetic field to function

 

[ChrisUK]

I can see your point but I don't even think it would effect that. Only effect I'd see them doing is causing the car to be slightly heavier

Anymore results yet sludgeguts?

 

[sludgeguts]

For some strange reason that didn't work either. I eventually found a list of BB codes though. It was supposed to be {fuelly=uk}value{/fuelly} swapping { for [
And just passed half a tank so not long 'till the next fill

And by heck did it sting as it was coming out

I did, of course, mean past.
Just done another refuel tonight, glad to see the average mpg is improving but still nothing like before.
I'll give it a few more refills to let the average settle down & if I don't get decent results then the magnets go back on.
of course, it would also be interesting to see just how the results are affected by my use of waste veg oil - i stopped using it when the snows came for fear of waxing & not got around to putting any in - so I'll get some more results sans magnets, then half a dozen fills with magnets then I'll start chucking in the chip fat again.

I must admit i'm getting better out my 1.4 petrol punto at the moment

We cross posted.

Last average 37.9mpg, this time 38.7

 

[skaramazoo]

That's ridiculous.

True! I agree too. Pity my wallet doesn't share our views though.

 

[ChrisUK]

True! I agree too. Pity my wallet doesn't share our views though.

Under what circumstances has this 'testing' occurred to give you those results.

You didn't put them on shortly after fixing / servicing / putting more air your car did you?

 

[Shadeyman]

Well its been a week now and MPG is up. Unfortunately I dont think its the magnets, more likely its the better weather we're having.

Been getting between 63 and 68 miles for each £10 worth of fuel I put in her while the roads were covered in snow. Topped up again this evening and recorded 75 miles for the last £10 I put put in.

I'll keep going for another week or two then remove the magnets and keep monitoring each £10 top up.

 

[Argonought]

I still can't understand why you guys aren't using trip 'B'

It really is so easy if you repeat the same run (whilst maintaining the same driving conditions) and it's also a good exercise in driving economically.

You only need to drive 4 miles or less to get quite an accurate result.

As Shadey says, low temperatures and snow will produce quite bad figures although black ice can produce surprisingly good figures due to very low friction between tyres & road and the fact the driver can't use the brakes or the accelerator

 

[skaramazoo]

....You didn't put them on shortly after fixing / servicing / putting more air your car did you?

To be honest with you, absolutely no repairs had been effected on the car just before I put on these magnets whatsoever. In addition, the weather parameter cannot come into the equation either, because throughout autumn and now in the winter the weather over here has been pretty stable with temperatures ranging from 5C to 20C. The only snow we've seen so far here was a little sleet for only a couple of days which - of course - is a joke compared to what you've been experiencing over there recently.
But, like I said, I am still a skeptic about the whole thing and I'm still testing it. Tonight I'll take a 220 km trip to Patras and after 2-3 days will do the same back to Athens. I have now filled the car up to the brim and will do the same when I get back home to measure fuel consumption.

 

[Hellcat]

Lets put some perspective on this.


With my normal driving I get around 45mpg from my 1.9 150bhp multijet Bravo. During the Ecodrive GP I drove more efficiently and got an average 60mpg on my daily drive to work and trips to the shop.

Now, I could have just put a packet of jaffa cakes in the boot at the same time - and based on your equation of:

mpg after fitting is 100% caused by change to car

then I can conclusively prove that putting a packet of jaffa cakes in the boot will give you a 33% increase in fuel ecconomy.

 

[skaramazoo]

You're making a very good point here. It goes without saying that all my fuel consumption measurements have been taken using a constant eco-friendly driving style. My Brava engine is not a 1.9 like yours but a 1.2 instead. Last night I drove 233 km to Patras where I am right now not exceeding 120 km/h at any stage whatsoever. I drove @ 120 Km/h for only about five minutes in total. I also drove within the city, was help up in traffic jams and as soon as I get back home I'm gonna top up again and see what the pump says.

 

[Hellcat]

Using the eco-drive software I can show that one journey can give me 63mpg yet another 58... but to me I drove the same - as efficiently as I could. During the actual Ecodrive GP final in Bologna, all the competitors set out in identical 500 twin airs to drive the same course, in the same weather only 10 minutes apart. MPG ranged massively.

The only way to prove this would be to use a rolling road, back to back to back with the same car.

 

[skaramazoo]

Yes, but each competitor's driving style differed from the others.

 

[Hellcat]

They were all driving as efficiently as possible, and had already proven they were the most efficient drivers in europe who had entered the competition.

My point is you can easily influence the mpg. The only true test is if you didn't know if the device was fitted or not.

 

[Argonought]

My point is you can easily influence the mpg. The only true test is if you didn't know if the device was fitted or not.

That's probably a fair point but consumption should be consistent over same run, same weather, same level of congestion and of course the same driver.

I actually did two identical town runs like this and was amazed that I got 50.1 mpg returned for both journeys (about 5 miles each using trip 'B')

Second that!
