Shell petrol stations.

Fact remains though even Planes only fly with what they need for the journey. They don't keep them brimmed to the max.

Lugging 40-60 kg of extra fuel over 100,000 miles is going to add up.

An aircraft take off mass could well be 50% fuel! Excess fuel increased the weight and hence lift demand, the plane flies at a higher angle of incidence for that lift massively increasing drag.

A) what operator would run an airline with a fuel burn like that
B) what’s that got to do with cars mass, it’s actualy related to speed by orders of magnitude over any slight mass change.


I guess it’s nice if you have a nice car and enjoy the “exposure” only for some people to realise how much you are putting then you are going back to cheese on toast or a Philadelphia sandwich. #chickslovefastcars
 
I will definitely have to test this next time. I will let my range go to zero for this one, then I will go to the petrol station and try to get the bill as high as possible to see how rich and important I feel.
 
Physiological studies suggest you will not only be more inclined to drive more often but also faster when you have a full tank. This is due to the higher concentration of smug in the tank. Please be careful playing such games.

Man on speedawareness course gave this as a case study to the cause of 99% speeding convictions.

That's got nothing to do with why they don't fill the tank.
They would actually fill the tank at airports with the lower cost if able.

Fuel economy is not the main reason they do this though, they cannot take off or land if they are too heavy. More fuel means they can carry less cargo. Airline fuel is a complex calculation and is very different to a cars.

there's definite scope for petrol tourism (an app?), when I learned momentum 99 was, last time, 128 in KingsLynn versus the Cambridgeshire 135, I will do smaller top-ups in anticipation of a big shop, since regularly drive in that vicinity.

Topping up to avoid condensation in cold weeather is a thing too - no ? or not in our warming climate ?

Hahaha. What?


So if I spend £1000 this year on fuel, but I top up in £20s, and next year I spend £1000 on fuel but top up in £80 a go.... You're telling me I will be richer next year even though I spend the same amount on fuel?

I thought it saved money putting £20s in

Condensation?

When I did my Speed Awareness Course, strangely the only think I remember from that was the speaker said was along the lines of "just fill your car to half way, no point carrying that extra weight, thus wasting fuel".

Also, I guess it depends how far is the state away from your house or go out of the way to fill up, if its on route then it makes sense to carry less weight.

I drive literally right past a Shell every day to and from work, but I still hate filling up. I'm happy to take that minuscule MPG hit in order to carry around more fuel. I'd be happy if my tank was 200 litres then I'd have to do it even less often.

Are you really citing a bloke from a speed awareness course as an authoritative speaker on the subject? lol

the 'old' - air in the spare space in the tank condensing overnight and contributing to water at base of tank .. tanks are poly lined but ... if it gets towards engine ....

You have separators plus fuel has additives that hold water in suspension so you don't end up water in your tank.
 
Like so many things how you drive and where will affect the impact of having a full tank vs say a half tank. On most cars thats going to be 20-30kgs. so very low single digit % increase in car weight

If most of your journey is spent in stop start etc your probably going to see no diff, as your wasting the vast majority of the energy being produced anyway.

If your cruising along at a fixed speed then any extra weight will require more energy to keep its momentum.

But even using the long range cruising, that extra stop or two for fuel will probably use more fuel than caring the extra to begin with.

I wonder if people doing it for reasons of fuel economy don't wear heavy clothes pair of jeans can weigh a fair bit more than shorts, certainly don't wear a coat, make sure you go to the toilet before driving, don't fill that windscreen washer fluid either that's an extra few liters.
What a joke. I bet these are the same people that do their shopping at the petrol station as well and seem to like spending as long as possible there.
