'fuel economy calculator' iphone app

allthingsmustpass

I replied to another thread today where someone was asking about money savings apps, thought it deserved its own thread in view of the high petrol prices.

Since the 1p a litre cut announced in todays budget is pretty small beer (saving of less than 50p on a 60 quid fill up) there's other things you can do to reduce the fuel you use, you can measure it with the 'fuel economy calculator' app if you've got an iphone.

Or just drive better...

How do you connect the iPhone to the vehicle fuel system so it can measure the flow rate?
Is that a seperate piece of hardware I have to pay for, or does it come with the app?

How will that save any fuel?

So by punching all the figures miles/litres cost etc into the I-Phone rather than crunching the figures in my head I could save money?......

I use the full Road Trip app and set up a duplicate vehicle to record my fuel use. This way I can compare my previous fuel use with my new fuel use. Both sets of figures are easily exported for Excel use and further analysis if I want.

No extra hardware required. The idea is you tap in some details when you fill up at the petrol station and over a couple of stops that information is enough for it work out your mpg. You can then see if it sounds about right, which might lead you to find your car is drinking more than it should so solving that will lead to a saving. Or you can try out adjusting how you drive, to see how much of a difference that makes to your consumption... Can do like the previous poster suggested and have 2 vehicles logged as a before and after.

Also since you're logging your fuel stops it can tell you what you're spending on average per month on fuel to help you budget, and it gives you some other analysis of the stuff you enter.

If you're interested it's explained in the apps description on the app store, go take a look if you're interested and have an iPhone.

It's 59p.

Here's a cheaper and simpler version with some fuel saving tips. I don't have or intend having an isomething so their "apps are of no use to me http://www.torquecars.com/tools/uk-mpg-calculator.php
Saves my tired brain when calculating fill up to fill up!

I was taking the pee mate, if I want to know how much I'm getting to the gallon then I make a note of how many litres I put in, reset the trip counter, then read the trip counter after and do the simple math.

If I want it extra accurate, then the only reliable way is to brim fill the tank, reset the trip, drive for (say) 100 miles, brim fill the tank again, read from the pump how many litres have gone in, then once again apply basic arithmetic.

Much easier, silly me! I think you'd spend more than 59p on the lead in your pencil, but whatever floats your boat.
