New car uses more fuel in the beginning?

[BigglesPiP]

Maybe ECU is "learning" the fuel power?

Won't take anywhere near 300Km for an ECU to learn the engine.

However the engine will take that or longer to "bed in".

new cars always use more.. mpg will increase when the car is run in

Is it running on E85?

FFVs experience no loss in performance when operating on E85. However, since a gallon of ethanol contains less energy than a gallon of gasoline, FFVs typically get about 20-30% fewer miles per gallon when fueled with E85.

In case you weren't aware

I find, driving the mixed fleet of 3 year old or less trucks at work, that the newer ones return considerably poorer consumption than one thats already done a couple of 100,000 km, the difference is usually about 1.5mpg (which in an HGV is a lot!)

when they're only doing 8-11mpg yeah i'd say so too!

Is it running on E85?

No, Euro95 as there are no E85 pumps close and the price is 50% higher.

I know about the extra fuel consumption of E85 but the advantage is that it gives more power

I bought a 1.8 Flexifuel as it was a discounted deal and cheaper than a 1.6 with a business pack as well.

No that bad really i get under 28mpg from my pug 307 2.0 thats over the last 3000 miles

I thought engines came pretty much run in nowadays?

I think the onboard computer is a bit confused, maybe because it takes time to get a reliable reading, today I watched the real-time fuel consumption meter on my way to work, and it was no way a 25mpg average, it was way higher than that, even with the traffic lights, almost all the way it was ~38mpg when driving 50mph and obviously when accelerating it was way higher so I doubt the average is really 25mpg.

The average even went down from 11.1L/100KM to 11.0L/100KM in 15KM so I have no idea where the high fuel consumption of the first half of the fueltank came from.

I have a new car about very 6 months and it usually takes about 2-3,000 before the mpg settles down.

Nope.

Engines are normally driven by the manufacturer for ~2-4 miles, but that is about it. Most manufacturers give recommended running/bedding in procedures in handbooks.

The mileage on my car was zero (don't know how it got out of the factory and onto transport though )

My girlfriend got a new car a few months ago and that had 6KM's when she got it.

Good point about the manual though, I will have a RTFM when I get home

Digital odometer? It may be that the PDI procedure starts the clock.

Yes, I have digital meter, but so does my girlfriends car, but a much simpler display/computer.

 

[jamief]

I *think* a lot of new cars have a facility whereby if the mileage if < (for example) 15 miles, the PDI check allows this to be reset to 0, one time only.
