Best and Worst On One Tank

[Hag]

I was wondering what's the furthest I can expect to get out a full tank of petrol in a Standard S2 Elise (well, a Type 72 that has a standard engine) and what's the worst case scenario? Going to be driving 300 miles or so tomorrow...should a full tank get me there?

Gonna be tight by my calculations.

Roughly speaking
Consumption = 40 mpg
Capacity = 32 litres
4 litres in a gallon

Works out at 320 miles on a full tank.

Personally I'd be filling up near destination

[kambites]

There's 4.6 litres in a (UK) gallon. 32/4.6 = 7 gallons of petrol.
so at 40mpg that's 7x40 = 280 miles.

I wouldn't try more than 250 myself.

A 111S at a constant 70 should manage 300 miles on a tank (that'd be 43mpg). Not sure about a standard car.

Thanks kambites, I did say roughly ;o)

297 is my best (motorways - northumberland to Birmingham and part way back)

203 is my worst (major hooning)

Makes no difference whether I use unleaded or v-power/ultimate.



ETA: Cannot remeber how bad it was when tracked.

Just didn't want to leave him stranded 40 miles short of a petrol station

ETA: In practice I get around 38mpg from my 111S on 90% short-trip suburban driving which equates to about 240 miles from a tank. I suspect that on the motorway (with the roof on) I would get 45-50mpg if I stuck to the speed limit.

Thanks guys, for the information. Will be careful to top up before Pembroke.

Looking forward to the spin!

Cant remember the number of miles before filling but by best in an S1 with sprts exhaust and filter (at the time) was 45mpg for a touring holiday and 12mpg at Bedford autodrome!

Cheers,

I'll post up the results of the run!

My worst with 111R is 200 km (128 mls) (Spa-francorchamps) with one tank and affraid to run out of fuel as I put 42 liters in it.
It means 21 l/100 km or about 14 mpg

I've seen over 400 miles out of a tank on my S1 but nobody ever believes me.

...........good effort guy.

I've decided to see how I far I get reading from full to half full and judge how far can go on what's left, but I'll be filling up at a third full.

Epic journey tomorrow Picking up the Elise in Heathfield, East Sussex and driving it to Pembroke to its new home in Ireland.

I can't wait!

my last trip to bedford saw nearly 2 tanks of fuel to 160 miles done on track !!!

I don't know if this is relevant because it seems to me that the indicator is not linear. It takes 70 mls to burn the first black square (and you expect to do 350 mls with the tank without problem) then 50 for the second and so on. Finally it is hard to do more than 200-250 mls with one tank.
Does anyone else experience this?

Over 1000 miles I used more petrol in my exige s than a 1000 miles in my csl and I nearly always drove my csl in sport mode in S6. I think I turned up to a washly day in my csl with less than a quarter of a tank and that lasted to lunchtime.

[jamwill79]

130 track miles at Brands on Monday. 65 Litres of fuel.

[Altrezia]

Currently at 140miles out of this tank, with 32 litres remaining. (according to the dash)

gotta love motorways.

Comparing with the exige S of a friend during track days, the S uses about 15% more fuel than my 111R....for the same lap times ()

I'll be careful and it'll be motorway miles all the way, with the Hard top on.
