I tend to fill the tank when the needle drops below the half way mark. Today, the needle was suggesting a nearly empty fuel tank. Only took 33.08 litres to fill it! I was expecting to get more in.

I suggest that's about normal for a Jazz.

Yes, about normal to have 6 or 7 litres left. Much rather have a fuel gauge and light that give you a bit of range to find a service station ( which seem to be getting larger but further apart ) than one like Mini or Fiat that leave you with about 20 miles in the tank. The fuel gauge is neither here or there to me as I rarely let tank get below 50%.
As long as you know about the gauge I don't see a problem, the tank on Jazz is flatter than normal tanks because it fits under front seats.
-
Well, it's good to know the guage is normal. Thanks.
I mostly refill at half way, as I don't want any junk at the bottom of the tank getting in the fuel system and creating problems.

I treated mine to a drink of higher octane Tesco unleaded this morning, was feeling generous :D 134.9p a litre :o

Modern fuels, big filling stations, and particularly modern petrol tanks have pretty well removed that problem.

I'm sure you're right. Its just old logic and something I must have read/heard years ago.

I normally wait until the low fuel light comes on before topping up, but at the moment I never know when I may get a call out through the night so I am topping up at about the quarter tank.
-
I know what you mean. When we were on call last year with my Mother in law, the tank was always kept >1/2 full.

We have already been called three times to the hospital, once late at night. The last thing I need is having to search for an all-night filling station.

Don't start me on fuel gauges. >:(
I wish they'd have the option at least of displaying how many litres of fuel are actually in the tank, especially on motorbikes.
The Honda NC bikes started off with bars on an LCD screen which went down then the last one flashed, however there was no telling how long it had been flashing for if you hadn't spotted it, and there was actually about 1/4 of the tank still remaining when it began so you didn't want to refuel for a while in order to get a decent range.
The next generation had a display which began to count up how much (litres/gallons selectable) had been used after the flashing started, but it didn't actually tell you how much was left, you had to work that out yourself based on knowing how much was left when the flashing/count-up started.
FFS, why not just display how many litres are actually in the tank, that's all I want to know.
.......... and breathe ............ ::)
-
On bikes, I just reset the trip, and refill soon after 100 miles. I know the range is there for more, but it's worked well for me. I don't ride long distances in one go anyway.
My Suzuki Bandit was the last big bike I had with a actual reserve tap. Old school idea, not sure why manufacturers did away with that.

I had a lot of bikes without a fuel gauge or low fuel light - just had to swish the tank side to side and guess by the sound how much fuel was in there ( not even a dipstick ) my present bike has a miles remaining, bar gauge with 1/2 gallon per segment and low fuel light.. All this miles remaining etc is the dumbing down of information, a lot of drivers don't even know how many miles a litre will take them. Thing is though once you have used the vehicle a few times and filled the tank you now how much fuel is left when gauge reads half ful, when it reads empty, or after the low fuel light has come on.

The old tap was something that if you didn't turn it off you could end up with an engine full of petrol, then the vacuum tap appeared where engine inlet manifold vacuum opened the fuel supply - most bikes for many years now have had fuel injection and no tap required.

The fuel pump will pick up fuel from lowest point in tank anyway, even with a full tank - the pickup isn't floating so that it drops as tank empties. Most fuel systems today have big and efficient filters because fuel injection doesn't like bits in the fuel ( the injector holes are very fine ). Pretty much every car built since 2000 will have a plastic fuel tank, so low fuel level and condensation causing rust is a thing of the past.
-
This may divide opinion and I'm certainly no expert on these things, but a mechanic I know told me many years ago that consistently using almost your entire fuel tank was a good thing as you were more likely to avoid poor quality fuel accumulating at the bottom (because it would have been processed by the engine for its intended purpose).
Ever since then, and on a range of previous cars, I have almost always waited for the fuel warning light to come on before filling up (when there is approx. 5-7 litres left in a 40 litre tank). Not sure if that mechanic was right or I've just been lucky, but I've never had any engine problems.
-
By choice, I always wait until the low fuel light comes on before I top up.
-
I'm another half tank topup.
I always worry that with the low fuel light on ther'll be a problem, garage shut, card fails or something.

I never let tank get below 50% and I have never had a problem - the fuel pump gets its fuel from lowest point of tank anyway so bad fuel cannot collect there, in a motorbike the fuel outlet is at bottom of tank. Some extreme MPG drivers like to keep to fuel level low to save weight - I am not one of them, a car without fuel is a road ornament ( or good for keeping chickens in ). I am noticing that a lot of small service stations are closing and the remaining ones are larger but further apart.
-

I always fill up at the same filling station every time and carry three payment cards. If all three fail, tough. The petrol will already be in the tank!
If I have something special on I will have the tank filled in advance. At the moment I am getting called out at all times of the day and night so never let the tank get lower than to have enough petrol to get to the Royal Infirmary and back.

I haven't had a card fail in years. Got so used to them being reliable. Have my debit card, and the Mastercard for back up. Certainly never pay in cash anymore.
Tend to use our local Texaco as the owners are such a friendly bunch and the reward gives 1p litre back. Failing that, our Asda. I do like pay at pump for convenience.
-
It's just me being me.
I just like to have the car in the garage with at least half a tank so I'm covered.
-
I tend to fill up when I get to just under 100 miles remaining on the display. Gone are the days of driving as a teenager constantly with the low fuel light on and filling up with a fivers worth :-[
-
When I was a teenager a fivers worth would fill the tank, WITH CHANGE.

In the early 70's my Mini took £1.10s to brim it.

5/- a gallon for long enough.

Yeah we had non of the global warming stuff to worry about, just being nuked by Russia or blown up by Irish, freezing to death because miners were on strike ... happy days! Early 1970's nearly had fuel rationing ( they actually issued the vouchers ) because middle east / OPEC was kicking off about something or other.
-
When I passed my test, Esso premium 5 star, from one of the four privately owned filling stations in our small town (no supermarket petrol then - no supermarkets), was 4/4d a gallon (22p).
-
I have no idea what price fuel was in '89 when I passed. But it was around then that fuel started to be sold in litres, and unleaded was making an appearance.
As a teenager, I could never afford to fill the car in one go. Mind you, some of my earlier motors I'm not sure I had confidence they would last long enough to use the entire tankfull even if I had had the money!! :D
I only started paying attention to fuel prices during the fuel strike of 2000. Remember that?

Look at all those lovely cars. Lots of red motors and not an SUV in sight, Suzuki Vitara aside! Only three German cars in the photo, I bet there would a lot more of them today.
-
The lowest price I ever paid for a gallon of fuel was 3s/10d which was in 1964, of course it rocketed up in price in 1973 at the time of mid-east war and I think I might still have the rationing coupons somewhere, never used thankfully.

We were in North Wales and actually got caught up in the tanker blockade on A55 - luckily had enough fuel to get back home OK.

I cannot remember the 2000 fuel strike. I was travelling back and forward from Fife to Greenock every day, for work at that time and I cannot remember having problems getting petrol. Perhaps it was not as bad here as elsewhere in the country.

Could be a vision of the future when we’re all waiting a few hours to charge our Ev’s halfway along the motorway.

You might be right! Scary thought for EV'ers.
I can remember that fuel was hard to find in Cambridge during the strike. I recall waiting in a line of cars for 30 mins.
Amazing how quick we take supplies for granted, and then last year we all got reminded about shortages with food and loo rolls caused by panic buying.
-
I know, bad times. I’m still trying to buy loft boards, people will stockpile anything it seems….

Or a power cut? ;)

During the ~2000 fuel shortage I'd just topped up so I knew I had just over 2 weeks fuel in the car for commuting at 20 miles each way.
On the second week I was almost the only car on the westbound section of the M25. It was an uncanny feeling.
Fortunately I managed to get the rationed £20 in on the second Sunday so I didn't need to public transport it.
-
I can remember the 1956 Suez crisis that resulted in fuel rationing country-wide due to the Canal being closed. I was around seven and my maternal grandfather, who lived in Stalybridge, Cheshire, had a Humber Super Snipe that he regularly drove down to my parents' home in Selsdon, Surrey. In 1956, he duly arrived and then couldn't return home as it was too complicated to fill-up as most petrol stations rapidly sold out and the lovely Humber wasn't particularly economical. So he and my gran had to stay 'darn sarf' for a couple of months during which I can remember queueing outside the pumps in Selsdon to obtain our allowed few gallons!

The most I’ve ever filled into my car was 34.00L. That was one of the scariest moments I had when I had already pushed to the limit by ignoring the warning light and drove on for several miles. Literally, I felt the car start to splutter afew times as I entered a BP station that was open (bad luck that my usual ones were all closed for the night, or refuelling!)! So relieved, but now I know what’s the maximum capacity! Hahaha!
I also reset my driving range “A” setting after each refuel. Typically get to 280-320miles range, depending on how hilly, traffic, seasons and if using AC. So, now trained myself to start looking for petrol stations about 260mile mark.

Usually I don't start thinking about petrol until the 400-mile mark with my Mk1. My largest top-up is 38.6 litres.

Woah! That’s excellent range!
For long distance trips esp to countryside camping, I also bring along a 5L petrol canister for emergency. It’s a cheap reassurance, but even tightly screwing the cap on, and being careful with not dripping any, there’s still a faint waft of petrol when I put it in the boot. Even putting it in a plastic bag and tying that up only helped a little (and I’m not certain that’s a good idea either!). Does anyone have a good tips on how to manage that?
-
The Mk2 has a strangely shaped petrol tank which makes it difficult to measure. When it indicates empty there's about 8L left in it. Also the needle on the gauge moves more slowly in the 50-100% region than in the 0-50% region.
I test drove mine (an ex-demonstator from the first batch of Mk2s) on country back roads in N Wales with the fuel gauge showing empty. The petrol station associated with the dealership had missed out on a delivery that day.
-
So, thought I would see 'how low I dare go' the other day. Little Jazz reckoned he was about bone dry and only 23 miles left in the tank. Right then, I reckon I'll get about 40 litres in........

So there was still nearly 9 litres in the tank! ::) Pessimistic.
On the plus side, 53.27 mpg is brilliant. :D

My Suzuki Bandit was the last big bike I had with a actual reserve tap. Old school idea, not sure why manufacturers did away with that.
I had a Suzuki RG500 motorcycle, square 4 2-stroke engine 67 miles on 3 gallons was typical and on the A1, fuel stops were an hourly event, fuel consumption in the main independent of road speed, in fact the faster I drove the better the economy!. The high output engine, rated by Suzuki at 95 bhp or 190 bhp / litre, burned 3 gallons per hour, it was up to you as to how many miles you could accumulate in that hour. Riding the Rg500 was akin to being saddled to a missile such was the scintillating performance.
-
None of you have ever lived! :P
In the 1980s I drove my very own Jaguar XJ6..and towed a caravan
At 60mph err,, 70mph.
I recall each of the two fuel tanks (switchable) held about 10 gallons (alcohol. age and time mean I cannot recall exactly_)
When you achieve 13mpg , switching fuel tanks and visiting fuel stations become a common occurrence.. 8) 8) 8)
-
13mpg! Blimey. Do you have your own oil field Sheik madasafish? ;D

At an indicated "empty" you've got between 6 and 8 litres left in the Mk2 Jazz. It's all due to the unusual shape of the tank. They made a feature out of it by marketing it as a "reserve".
-
I had a Mk 1 Triumph 2.5 PI in which the fuel injectors were shot. When I sold it I told the guy, "I have to be honest. I have had 18 mpg out of it.". What I didn't tell him that was the best I had had. 9 mpg was my average. I had to replace the sooty spark plugs every day. Luckily I had about 5 sets of them (30) and access to a sandblaster.

The fuel gauge on Honda Jazz’s are indeed very pessimistic. The light on my mk1 Jazz comes on with around 9 or so litres left (meaning a 34 litres fill up) but because I’m an idiot I like to stretch it and play the lottery. Current personal record is 40.1 litres in a 42 litre tank, I really was running on fumes that day.
So many people panic about the fuel light when they really don’t need to. Like I said, my fuel light comes on with 9 litres left so at 45mpg that rices me around 90 miles of running before empty so people who rush to the pump the second the light comes on don’t need to. If the next fuel pump isn’t for 30 miles, don’t worry about it.

I would suggest your mechanic has expressed an opinion :). If in doubt, I think the prudent approach is to avoid the risk of any rubbish (dead flies, dust, dirt, you name it) that has collected at the bottom of the tank, especially with older vehicles.
-
I have intentionally driven fuel tank empty on many cars to see where the needle goes when the tank is empty and how much fuel can be filled then. And in all those cars the needle has fallen below the empty line before it's all used.
Haven't done it with my GK Jazz, because digital fuel display has so coarse resolution and it will not present anything less than empty. Would be nice to see the volume though...

Both approaches are difficult to give reason. The intake of the fuel line is always at same level from the bottom no matter how much fuel there is in the tank. Only the rubbish on the surface can get into the system if driving until the tank is empty.
-

I agree, the intake level does not change as the fuel level decreases, so any water ( which is heavier than petrol ) would be sucked up whether tank was full or empty. There is a large filter in the tank so and solid debris on the 'surface' of the fuel should not get through either. Once you have run a car to empty light once you should know how much fuel is left anyway. IMHO Jazz reserve is better than only having 1 litre left when light flashes ( service stations in UK these days seem to be larger but are also further apart ). Personally I never really let my tank get below half way because you never know when an emergency may arise and you need to use car.
-
Same here, topup at 50% left ....... because you never know
-
I had a Mk2 Fiat Punto where the low fuel light used to come on very early, just under a quarter of a tank if I remember, much earlier than on any other make I've owned. I learn't to drive in Fiat Uno and that would the same, my driving instructor just said to ignore it!
-

Just took a short walk to my local Tesco, 06:20, and there is a nose to tail procession as they have to go round the roundabout and back out to the main road as they are shut, run out.

There's no more reliable way to cause panic than to go round saying "Nothing to see here. Move along." when people are seeing others queueing.
One wonders if we'll have a repeat of 2001 if the "Insulate" protesters get in on the act too.
