Fiat Punto 1.3 multijet 2004 ...... 90.2 mpg!

Postby nigelcut » Thu Sep 19, 2013 7:15 pm

Hello
Just interested in comparing economy figures for different cars. I normally achieve 70 mpg plus (official combined figure is 62.8 mpg) driving at around 55 to 60 mph. On my daily 35 mile commute trip (mainly motorway) its 75 mpg.
Best achieved 90,2 mpg on 504 mile round trip (overnight stop half way) average speed 49 mph
(all figures from the trip computer which I regularly check for accuracy and record on the fuelly site.) Car has done 84,000 miles and runs on Continental EcoContact 5 tyres (though I will be using different brand next time). I do not hold up traffic, I go with the flow!
I use cheapest supermarket diesel - has anyone done comparative tests with the more expensive fuels eg Shell V-power?

Hi Nigel and welcome to the forum. Just added you (The Dyson) on my Fuelly dashboard (FR-V) - nice numbers, well done on beating the combined figure for your car, 69.8mpg is excellent :D

Nearly every tank I've filled up with is supermarket diesel. I am actually considering a tank of Shell V-Power next time as I have £60+ of fuel vouchers to use (that cost me £30) from an offer months ago that have recently landed on my doormat!
I've heard many conflicting reports on whether it's worth using premium fuel and I err on the side of it's probably not but I have no proof. It's going to be difficult to tell if it makes any difference as there as so many variables in my normal driving, 2 lots of roadworks going to and from work, bad traffic going home, how many hypermiling techniques I use, the outside temperature, the percentage of the tank that is commuting, etc.
Have you had problems with the Conti Eco's?
I've got Michelin Energy Savers on the front pumped up to 60psi and some Bridgestones (non eco - been on 4 years) on the rear at 55psi. I've been really pleased with the Energy Savers - had them on over 3 years (over 24,000 miles) and there's still some wear left on them. Previous front tyres haven't lasted as long (under 20k) as my car is pretty heavy on front tyres with a 2.2 litre engine bearing down on them!

Thank you. Just realised I haven't added the figures for my 90 mpg run onto fuelly yet! That should edge the average up a bit more.
The Conti Ecos are fine, but I was hoping for better wear (the fronts are 3/4 worn after 20k). However, my hypermiling techniques include faster corner speeds than ideal for good tyre wear (all kinetic energy available is used to achieve maximum distance, and some roundabouts are just too tight for my liking!) I was thinking about the Energy savers next, but not convinced of any improvement with the Conti Ecos over Avon ZZ5. That tyre pressure looks very high - I would have expected excessive central tread wear. I have only gone 5 psi higher than standard so far. I think I'll try +10psi (41psi) next if you are not having problems.
Look forward to your tests with the V-Power (though my thoughts are as yours :) )

I do the same thing on roundabouts, when possible... Usually make a standard 1-lane roundabout in 3rd or even 4th gear at 40km/h (25mph), to conserve as much energy as possible when exiting the roundabout.

I think the wear and tear on tires does even out with slow and steady driving in other conditions, though. Less breaking and acceleration = less wear.

Good figures on the Octavia - especially as it is a large car. How did you manage to get the 100 mpg? (or the 79 mpg for that matter :geek: )

Why, by using a number of techniques that are alltogether called "hypermiling"! ;)

Seriously, I seem to keep getting better and better results. I know the car, I feel a difference of 5rpm in my engine, so results are going up.

The 100mpg was actually achieved on a 7 mile trip from my home in the village to the nearby town. It was an evening (no traffic), dry road, and the road is more or less downhill, so I got an easy 2,8 liters per 100km consumption (100mpg US) going in that direction.
Now the other way around should help clear things up: on the way back, my consumption was 4,2 liters per 100km (67mpg UK). So you can see how it evened out.

The 79mpg was done by driving for two weeks from home to work and back. It's 62km going there and 67 going back (because I take a different route to avoid congestions). I know the road like the back of my hand and could probably drive it with my eyes closed. I know how much to press my gas pedal for each stretch of the road, I know where I can release the pedal and where I can conserve energy. All this allowed me a very good result, which in the future I fully intend to make even better :)
