Fuel fill up to max?

[mustang1]

Do you fill your car's fuel tank to max, run it dry then refill? Or do you always fill to a certain amount of money?

I always fill to max and then refill when it's about 10% remaining. Others I know always fill £10 at a time. I always figured that wastes more time. I'm not sure I could drive too far on £10.

Filling a fuel tank to the max is very fuel inefficient - you're basically carrying an extra person around with you all the time.

Max.

Life’s too short.

That's about the size of it and how much convenience you want.

I fill up to nearly full then run down to 10%...... but I do know its inneficient.
I weigh up the extra consumption Vs the wasted time filling up 3 times more often.

I wait until the petrol pump light starts flashing red and then fill it up to the top. Stopping unnecessarily at a petrol station wastes time.

This is some sort of joke, right?

Is that actually true ? You will have to factor in the wasted kinetic energy of braking a ton and a half to a halt, idling / maneouveuring, energy of starter motor, idling a bit more whilst turning out, then accelerating back up to speed.

It's deadly serious.

normally yes but not when it's hot weather

You forgot the cost of driving twenty miles out of your way to get fuel that costs a penny a litre less.

I sometimes put £20 in but mostly I run it nearly dry, leave it until MrsF needs it, gives in and fills it up. My late father was like @Si-c, his cars were always running on fumes as he thought that economical.

Max. It's only a 33 litre tank, and if I'm on the SAR callout rota I don't want to waste time fannying with fill ups.

If we're doing a big journey we'll top up, but £30 usually sees us through 2 weeks.

My late, older BiL never filled his car up. He not only drove on fumes but a wing and a prayer. He ran out so often that before anyone could say, oh no, or the car had stopped rolling, he was out grabbed the can out of the boot, stuck his thumb out and disappeared. Of course he never had any money either so his watch spent more time in hock than on his wrist. And he didn't just do this in Britain but all round Europe, getting garage owners out of pubs, beds and restaurants, in sleepy villages whilst we all played I spy in the car and fruitlessly tried to find a radio station.

My car is always full!
