hey guys,
i keep hearing about these clip on magnets which simply clip on to your fuel line and separate the fuel molecules for easier burning of the fuel. This is supposed to give you a 15% decrease in fuel useage. Has anyone tried them and have some feedback. Also i was wondering about those hiclones which fit in the piping between the airbox and the throttle body(which also apparently give 15% decrease in fuel useage). Just wondering if anyone has any experience with these. Especially if they would work on a V8. Coz those hiclones look pretty basic.
Cheers

It's all bull****.
How's that for an honest answer?
Understanding a little about the chemical nature of petrols I can tell you that there's absoloutly nothing that a magnet that you stick on the fuel lines would do.
As for the hiclone...the best way to get increases in power and/or fuel economy are to have a smooth airflow into the cylinder. Which is why so many people get their heads polished (the polishing removes small burrs left from the casting process which disturb airflow). The hiclone does the exact opposite, it actually creates a disturbed air flow.
If you want to ensure that you're getting the very best fuel figures that you can, get a good air filter (K&N panel filter, or a FinerFilter panel filter) and a Cold Air Intake, make sure that you have good quality spark plugs, leads and that your injectors are doing the right thing. Use a good quality oil (Penrite is my oil of choice), and keep your tyres pumped up.
Car manufacturers tyre pressure specifications are usually softer than they need to be, this increases tyre wear, but gives a much better ride (supposedly). I still have 14" steelies on my VN and I run 36psi all around. It's a little firmer than what Holden specify, but tyres last longer, and fuel usage is down.
Another way to save money on fuel is to use the right fuel. (from a previous post on this issue) I'm going to do the following calculations based on a 50L amount of fuel:
PULP=9.09L/100km
ULP=12.2L/100km
That's a difference of 25.5%
The price difference between ULP and PULP is only (approx) 6% You're much better off paying the little bit extra per Ltr at the servo. It will actually SAVE you money because of the difference in fuel usage.
If you couldn't follow that here it is without the numbers (just the logic). You go further on PULP than you do on the same volume of unleaded (not true for all cars, but it is for this case), the extra distance you get out of the PULP more than makes up for the increase in the price per litre. The more expensive the fuel gets, the better off you are buying PULP. If fuel was out at $2 per ltr for ULP and $2.10 for PULP that's about a 5% difference. Now the performance of you car isn't going to change *hopefully*. I've worked it out that for my car, unless ulp fuel goes back down to less than 91.8cpl I'm better off buying PULP.
Find the right fuel for your car and you're laughing.
See http://www.vncommodore.com/forum/topic.asp?TOPIC_ID=218&whichpage=1 for a really good read on fuel figures. I've got a full spreadsheet setup in excel that keeps track of all my figures, maybe you should look at doing something similar to work it all out. |

LOAD OF SH!T!
even if they did have some sort of magical way of saving fuel with magnets(yep thats wat most of them are), the price u pay for them is setting u back money anyway, so ur further behind even before u put them on. |

Ok, here is a technical way of looking at it...
Fuel generally consists of many hydrocarbons which are burnt in the cyclinder for the combustion.
So, chemistry geeks know that large hydrocarbons are non-polar, which means they have NO CHARGES, or polarity!
Meaning, this magnet that sits on the fuel line, is magnetising NOTHING!! Since fuel has nothing to be magnetised!!!
Simple as that.  |

| i dont know if anyone saw on the news lately but car manufacturers are starting to put these "ionisers" on the new cars fuel lines for a way of saving fuel, personally i think it is a load of crap, but if the manufactureres are starting to use them... |
