Honda Jazz fuel consumption ???

[nij400]

I have recently bought a jazz and it seems to use a lot of fuel ie 500b of 95 gasohol = approx 130kms all town driving , 1000b = 300kms bkk to hh at stedy 120 to 130kph
Is this the norm for a vtech jazz?? Car has done 55000kms and full FSH .

1000b = 300kms bkk to hh at stedy 120 to 130kph

Bloody hell nij, my great lump of a Ford Ranger did Pattaya and back for 1000 Baht! Apart from traffic problems through Bangkok, my speed was about the same.

How many km's is that BB, I reckon it must be at least 650? I have a Pajero Sport and if I brim it from reserve it takes about 1800 baht and on mainly local runs I get about 625-650kms, so the Ranger must be considerably more economical, even allowing for your steady speed driving.

[Big Boy]

Yes, very economical on a run. Very thirsty around town though. It was quarter of a tank each way, and I have approximately a 12 gallon tank (sorry, I still do imperial). A full tank costs just under 2,000 Baht.

The numbers you have quoted at today's price for Gasohol 95 of 40.53 Baht / litre equal as follows:

500 Baht = 12.35 litres = 10.52 Km / litre = 29.73 MPG

1000 Baht = 24.67 litres = 12.16 Km / litre = 34.34 MPG

I am not sure of a "jazz" engine size, but if it is a small 4 cylinder I would expect around
16 Km / litre / 45 MPG.

I am always reminded of the old story of the lady driver complaining about fuel consumption. Her mechanic spent days going through the car and could find nothing wrong. Eventually, he said "take me for a drive so I can watch how you drive". In she hops, pulls out the choke knob, and hangs her hand bag on it!

Of course, modern cars with fuel injection systems do not have a "choke". BUT, they do have a system of enrichment for cold starting. This sometimes involves a separate "cold start" fuel injector, or more commonly, the electronic ECU takes care of it by reading an engine coolant temperature sensor, and adjusting the pulse width of the fuel injectors.

It is possible that there is a fault with the sensor / input circuit that leads the ECU to believe that the engine is always "cold", and it consequently increases the fuel supply to the injectors. A simple check with a laptop "test-book" would soon show if that is the problem.

The same does not apply to diesel engines.

130Kmh is 80mph, your little car is not designed to cruise efficiently at those speeds, slow down to 110kmh and you'll notice an improvement in fuel efficiency and not much loss of overall time taken.

BB did not do Pattaya and back on 1000b of 95 (24L) he might have tried on 1000b of diesel(33L) but I doubt it as it's 700Kms round trip so he'd need to be using 4.7l/100Km and no matter how light a foot he now has it won't be light enough to half the standard fuel consumption of a 2.5 Ford Duratorq. One way for 1000b of diesel - maybe, but both ways? no.
Sorry BB, your missus must have filled it up when you weren't looking.

Here are some specifications for the Jazz, although I know that these are not always representative of the real world:

Fuel consumption: extra-urban / city / highway / average combined:

(city cycle is based on typical European traffic)


l/100km: 6.1-7.7 / 8.6-10.9 / 7.8-10 / 8

mpg (imp.): 37-46 / 26-33 / 29-36 / 35.5

mpg (U.S.): 30-39 / 21-27 / 24-30 / 29.6

km/l: 13-16 / 9-12 / 10-13 / 12.6



Driving range:


extra-urban: 540-690 km / 340-430 miles

city: 380-480 km / 240-300 miles

highway: 430-540 km / 260-330 miles

average combined: 528 km / 328 miles

I have to agree with FH - I do the drive fairly regularly and it costs me a lot more than 1000 baht of gasohol 91 in my small Honda Brio 'eco' car for the round trip.

[brianks]

I have driven my Jazz for over 100,000 km and my overall average for ALL driving is between 15.5 - 16 kpl (about 35mpg) . I drive at 110 kph on highway and am careful with other types of driving. The numbers I am seeing in the post tell me something different is going on. Speeding, jamming on the brakes a lot and accelerating quickly off stops can kill any good kpl effort. I think the Jazz is an incredible package for all it does and has in it. Only big thing I miss is Cruise Control.

I filled up as I left Hua Hin, and I filled up just before I got back to Hua Hin. I know what it cost, and it was under 1000 Baht.

That is just monumental if true, I just did that same journey on a bike and it cost me about a grand in fuel, almost 750 kilometers (it was gasohol thou).

[Big Boy]

I thought it was brilliant at the time. As you guys are putting doubt in my mind, I will re-check my trip notes, and either confirm or apologise. Watch this space

This is not helping the OP, but something does not add up here.

All-New Ford Ranger Powers Ahead for Fuel Efficiency with Potent Diesel and Petrol Engines

Bangkok, Thailand, 23 Mar., 2011 – The all-new global Ford Ranger delivers more while sipping less, thanks to highly fuel-efficient engines that give the truck the power and torque to get the job done without burning a hole in the owner’s pocket

The 2.2-litre four-cylinder diesel engine comes with three different power outputs and can be mated to either the five- or six-speed transmissions, giving customers even greater choice. When fitted to a 4x2 model, it consumes as little as 7.6 L/100 km in a combined cycle1, making it one of the most fuel-efficient pickups in the segment ( I believe that this is the engine you have Big Boy)

7.6 L / 100 Km = 13.15 Kms / Litre = 37,06 MPG.

If your round trip to Pattaya was 700 Kms and cost 1,000 Baht = 33.44 Litres: that works out to: 20.93 Km / Litre = 58.96 MPG.

[STEVE G]

How big is your fuel tank BB? Ford Thailand say 80 L for the current model but that seems bigger than yours if you're saying 12 gallons.

I think you'll find that I queried this before in another thread. I'd read that, but my tank fills at around 12 gallons (just under 2000 Baht). I always calculate at 4.5 litres/gallon. I've left it until the low fuel light a couple of times, which I assume is about 0.5 gallon.
