Fuel economy - What do you get?

[highlandsflyer]

Two Pajeros, both LWB Extra Wide Mid Roof bricks of similar vintage, 1990, both 2.5 Intercooler Turbo Diesel, one tweaked and gets 22/25/28, the other well cared for low miles gets 25/28/30+. Currently running on discounted bio-diesel at 80 odds p/l.

Merc Sprinter 2.3 25/40 depending on load, etc. Bio again.

Beemer F650 55/70 ridden politely. Various other old bikes varying between 30 and 50 odds.

S-Max should be doing 50+ for the driving we have been doing but getting 35 odds, and that is actually 32 odds according to my brimming measurements. In for a major service soon so we shall see if things improve.

I brim everything, the extra weight of fuel to carry around is an insurance against getting stuck up a track with a 4x4. Once you start struggling off road you woof through fuel. It also means I am always aware of how much fuel I am going through; which with diesels especially is a great indicator to how well they are running.

Of all the cars I have had very few if any were honest about how much fuel they were using. Brimming a couple of times is worth doing so you can allow for the lies they tell.

Over the last 2500ish miles I have averaged 58.1mpg in a Focus Estate 1.6

It is a very practical car but it has been known to be out accelarated by glaciers. I don't generally bother with looking at the speedo, I just look out the window to see how far the sun has moved.

This has now gone up to 62.2mpg in around 2 and a half years. Figure obtained via the trip computer but confirmed by sums.

43.9mpg in a 2011 Mazda 2 1.35l VVT thing. :shock:

Costing me less than the last one (same model) did in fuel too.

Dare say it would be more if I drove down the M58 to work, but that adds 6 miles on to the journey.

Currently 49 mpg urban on '94 Clio 1.4 petrol, measured between pump and reserve light coming on.

89 325i Touring, straight 6, horrendous on fuel, but comes with a lovely sound track

I've got the same block and lovely noise but in a 525i sport, there's no urban/motorway comparisons here it's just 25mpg (if I drive sensibly)

Still positvely frugal compared to it's predecessor a Jag XJ6 4.0l , if I could get a good run with no red lights or coffin dodgers holding me up I could get 15mpg

I think i get on average about 30-35 out of the '97 318. It can get really good figures on a run, 45-50.

Around town it can drop off pretty spectacularly, so careful driving is worth the effort.

2007 Nissan Note 1.4

around 40mpg in combined driving.


1992 Mazda MX5 turbo

around 30mpg driving sensibly, 20-30mpg with a lead foot, and we're talking gallons per mile if thrashing it on track



tbh don't just look at the mpg, the road tax costs, servicing costs, spare parts costs etc all affect the overall picture, plus it depends how many miles you actually do as to whether going for a high mpg car will eventually pay off or not.

I could do better if I sorted out the iffy lambda sensor, as the engine is over fuelling at the moment, but the sensors are a bit out of my price range at this point in time and besides near fifty to gallon urban is not really to be sniffed at.

Don't forget depreciation - often one of the biggest costs of motoring for some people.

If you're definitely running rich, I'd spare a thought for the cat.
