400 Miles from a full tank, is this normal?

crussell · Post by **crussell** » Mon Mar 28, 2011 10:41 am

Im putting loads of questions on here I know but I want to know as much about my F as possible and get it up to/keep it up to scratch as its my daily driver.

I have just travelled 400 miles on a full tank and wandered if this is normal or if the fuel guage on my car might be slightly off.

As always any feedback is greatly appreciated

There's usually a few litres in the tank when the tank shows empty. Empty to brim capacity is 50 litres - but I usually bottle it and fill at 45 litres. 400 miles with my driving style sounds about right to me outside town.

Good to know, i am not a slow driver by any means, but economical in my method (no over revving and changing to fourth when doing 30 and not sticking to 3rd like most lady drivers i know seem to!!) having said this i have been enthusiastic a few times including leaving the owner of a new hyundai coupe a bit shocked and a new civic owner too who just couldnt keep up with me. Its economy has pleased me and its great when you do get a chance to put the foot down to hear that exhaust note at 3000rpm in third!!!
Didnt expect it to be so economical so its happy days for me!!!

let say it £1.30 liter.

how many liters is 400 miles, and what that price, per mile.

well impressed here?

mgf full tank.

400 miles

55 liters.

1.30 liter Morrison.

price 71.50.

55*1.30=£71.50p

number of liters, cost per liter, miles
55 * 1.30 / 400 = 8p mile

CAR = London to Scotland/Northampton = 400 miles
car = 71.50 petrol via Morrison at 1.30 a liter.

London Eco friendly transport.
train £130 all times except 16.50 = £70 not return

16p mile via friendly train except cheaper planed journeys.

car 6 hrs train 3 hrs

my mgf beats in price government standard train getting there, not return, me and the mgf hang onto another train for a free ride back lol

400 miles on a tank is a ball park figure, it's very attainable. Last year, crossing the Alps, Pyrenees and Dolomites with full fuel tanks, two people and a boot full of luggage the TF managed over 43mpg average (and we were not hanging around, we kicked them pretty hard when we could but had to be careful above 2,000 metres because of the snow). So, with (let's say) 11 gallons available over 450 miles is possible.

We are doing another more detailed trial this year when we drive to Montenegro, we will all log our fuel consumption and compare as none of the cars on the trip are mechanically alike.

I'm off to Italy in my F later this month and if these figures are correct then I shall be really happy. I'm a bit like Rob - I tend to fill up a bit sooner rather than running right down to the dregs. Don't forget that running out of fuel can do permanent damage to the Cat so it might not be ideal to try and go that extra mile. However even with knocking about locally I never have to fill up until I've done about 325 miles so I guess there's plenty left in when I do - I've never, ever put in more than 40 litres so perhaps I could run the gauge a little lower before I top-up.

I'm hoping to get slightly better gas mileage on the trip, which will be a steady motorway run from Nîmes, passing through Genoa to Rome and then down to Pompeii and the Amalfi coast.

As an aside, any of you thinking of a foreign trip (anywhere in Europe) this site can provide you with a motorway toll transponder on a short term rental:

On average, I'm refilling every 320 miles, having to put between 43 and 44 litres in the tank. That's 32.7 mpg.

400 miles from one tank? That'd be paradise!

I put in 53.75 litres once , which got me 483 miles of commuting. I have heard of 500 miles having been done and could match it if I could be bothered to try. My MPi gets a 41mpg average, driving normally, over the last 92000 miles worked out by dividing all miles/all fuel to 2 decimal points.
They are a very efficient engine and would be even more so without a cat and remapped to the original lean-burn design.

I get about 22mpg out of mine, which Im quite happy with

The original 1.1 and 1.4 litre K-series were developed with lean-burn in mind - but I wonder whether this can be achieved with a 1.8? Might be worth investigating, as the lean burn K-series would almost certainly pass MoT emissions without a cat.

On a recent trip back from the Lakes I managed to get 46mpg but that was keeping it at a steady 70mph and not going over 3,000 revs. Very boring but satisfying none-the-less with the price of petrol these days! That was worked out by filling the car to the brim before getting on the motorway, topping it up back at home to the brim and working out the cost, gallons and mileage. As soon as I put my foot down I might as well call in the tanker for some mid-air refuelling en-route...

thats appalling - my V8 does better mpg than that

Not in town I would have thought Colin! Depending on congestion even an MGF will drop below 30mpg

Me thinks that 22 may be a typo?

How easy is it to retro-engineer a stop-start system?

Hmm... could one adapt something like this, ala 200HPD?

I've never had less than 21mpg Rob, and that was to and from LeMans circuit and the campsite, and around the circuit

Not bad! You'll have me pining after a ZTT V8 again if you're not careful!

Post by **Mykel** » Tue Apr 05, 2011 7:48 pm

Haha! I almost made it today

365 miles before visiting the Favourite Multinational Company's Branch Office

This was during a long-distance drive to Frankfurt and back on the A3 motorway (up- and downhill most of the time) at a moderate speed of 80-90 mph. The only downside being that I had to top up 46.66 litres, giving me 35.5 mpg on that trip. Yet this was the second best value so far.

400 miles on a tank? Easy, providing you don't cane it.

I've just got home after an 1800 mile round trip to Italy, taking in Rome, Pompeii and the Amalfi coast. The secret to good fuel economy is to keep the engine at less than 3000 rpm (boring, yes, but economical, cruising at 74mph)

I achieved the following mileages....

Home to Sestri Levant - 377 miles - 38 litres -45.09mpg
Sestri to Rome - 400 miles - 40 litres - 45.45mpg
Rome to Pompeii - 339 miles - 39.4 litres - 39.1mpg ( includes a fast motorway run & a good spanking round the Amalfi Coast)
Naples to Portofino - 368 miles - 39.6 litres - 42.25mpg (running at 80mph)
Portofino to home - 351 miles - 35 litres - 45.58mpg

That's on a 14yr old 1.8mpi with just under 93K miles on the clock, so it CAN be done.
