Mpg increased by 15% (1 Viewer)

[Ipetchey]

With an extra 380kg our fuel consumption has improved by 15%, simply by inflating the tyres to the correct pressure.
A couple of weeks ago we purchased our new (to us) van and drove home 150+ miles with near unladen van weighing 3360kg and averaged around 25mpg. Today we drove 100+miles fully loaded weighing 3740kg and averaged 29mpg. Both similar roads and speeds (60mph on A1/A14). I can only put the better fuel consumption down to me increasing the tyre pressure. When we got home I inflated the tyres from around 55psi, to the recommended 79.5psi..... A bit noisier on concrete roads, but otherwise no noticeable difference driving.

We have a weigh-bridge in our village, so weighed vehicle empty as soon as we purchased it, then again this morning fully laden (with scooter in garage, generator, heavy awning, full fresh water etc) as we departed on route for Scotland for 6 weeks.

We have a 4250kg max van, so very pleased that we still have around 500kg spare, although the rear axle was only 100kg off the max, so we have moved as much forward out of the garage as we can.

Thats it then 20 bags of cement in the back tomoz
and 200lb in the tyres:thumb:
seriously thats about the best MPG improver you can do
Get the tyres right

500Kg spare capacity ...... that will be a lot of Scotch whisky then all paid for by the saving in fuel costs:thumb:

How can you measure the fuel consumption accurately over such short jouirneys?

I hope it's not the onboard computer as they are rediculously inaccurate with fuel consumption.

Now what you need is a set of Jim's tyre pressure thingies and you'll always know that they are at the right pressure. I'm very pleased with mine.

It was with the on board computer. I have found it to be quite accurate.

The Fiat unit oddly it does seem to learn - I'm not suggesting it has artificial intelligence but ex factory it's laughable and it gradually gets more accurate. When new mine said I had a range of 470 miles with only a quarter of tank of fuel!

Reset the thing a few times and it gets better.
