expected distance for a full tank
« on: January 05, 2018, 09:34:18 PM »
Lets say a person was to drive at 85 mph in a 1.4 ishift from Torquay to Norfolk, pretty much unhindered by traffic setting off at 5 am in the morning.

Would one expect to refill from a brimmed full tank when the light goes on after only 255 miles?

seems to be drinking a lot of juice at that speed.

If the light comes on at 6 lites remaining, and say 4.5 litres per gallon, thatís about 36 mpg? Whatís the thoughts of yíall?

ie is 255 miles a reasonable distance for a fully brimmed tanks at a speed of 85 mph?

36 mpg at 85 mph sounds pretty good to me. Doubling the speed needs four times the energy.

I agree with Jocko - once you get over 70 mpg plummets on most cars but especially on small ones.

My i-shift got up to Durham in full tank Shell V-Power from London, 300 miles with lights on and needle nearer to the end! But in town I only get up to 260. The tank is small may be? I expect 300 for this type of car but obviously not! Average 36-8 mpg.

At 42 litres they are relatively small capacity tanks. Iíve owned a 3.5 Honda Legend and a 2.8 BMW 5 series. Both the Honda and the BMW took about 90 litres.

The Legends lack of range / poor fuel efficiency was the reason I traded it in for the Jazz. At more than twice the tank capacity it managed a similar range on the motorway. I canít remember getting more than 130 miles out of it around Torquay on a full tank!

The BMW averaged about 33mpg at 90 mph on motorway. I could reliably get 450 miles on a single tank on the motor way. The urban was about 140 miles

I filled the thank yesterday, 28 litre, as i always fill when its still about a quarter full. 450km (280 miles), 45mpg, mostly short town trips. When mostly rural and highway trips it's better.

It's the speed and right foot, 85mph is thirsty. I hate speeding tickets, so 75mpg at a highway is my max. I am not a slow driver, never been, but looking ahead and anticipating (is also less braking) saves fuel.

Most cars are designed for a 400 mile range at their quoted MPG,  most probably at a steady 50 or 55 mph,  above this speed consumption rises rapidly.  This is even more apparent with electric cars where a spell at around 70 on the motorway can see a quoted 300+ mile range drop to nearer 200.

How you drive has a marked effect on MPG, if I stay around 70mph in my Civic 1.8VTEC I can easily get from our house to Falmouth in Cornwall (about 300 miles) on about 2/3 tank- the Civic loves motorways,  that is where a larger engine wins out,  but local mileage I get high 30's low 40's mpg. 
Some people will only consider you an expert if they agree with your point of view or advice,  when you give them advice they don't like they consider you an idiot

I used to dash about in the two bigger engined cars and NEVER got a ticket. Within 3 weeks for swapping for the jazz I got caught by a  hand held camera!

I'm usually under 80, and the mileage is a lot better, just in to the 40's mpg from what the read out says.

I'm lucky to get 400km per tank from our 09 1.5 Jazz Sport with 5 SPD auto... That's all town driving.
Why pay someone to do it when you can do it yourself!

Regularly drive from Redruth to Preston for family commitments fill up to the brim before setting off, door to door 351 miles and apart from a few miles all dual carriageway and motorway, steady 70 to 75 mph the petrol warning on the Jazz always came on at around 300 miles whereas the Civic still has plenty in just below a quarter on arrival.

My Jazz-used mainly for short runs averages 42.7mpg (fuelly) over 5 years. So into the red at c310miles.. leaving another 40miles reserve.
On long runs it easily averages 48mpg - depending on weather and traffic--- so roughly 350miles +40 reserve

I get 400 miles to a tankful. I try and run it till the light comes on, unless I have a longer journey planned and I know it has not far to go. I have had to fill the tank 40 times since getting the car 18 months ago, so roughly two tankfuls a month.

I've had 400 miles to a tank twice in my nearly 5 years of Jazz ownership (2 cars, a 2010 and 2013) and there was obviously a bit left as the light didn't come on. My best tank was just over 56 mpg and I had 54 mpg back in September. Ideal conditions for best mpg? Motorway traffic with speed restrictions!

Lowest mpg remains at 33.8.

I just drove up to Marlow Bottom from Torquay at about the 75 mark and it read as 42 mpg

Interestingly the return trip was up at 45 mpg, and possibly a tad faster.

Iím guessing there is an overall incline that gets higher the further east you drive from Devon.

Those extended 50 mph segments with average speed cameras do wonders for economic driving, if nothing else:)

The worst top up I have ever had, since buying the car 18 months ago, was 46.6 mpg.
