A '60s car would definitely have been built for leaded fuel. My brother and I shared my dad's old '72 Datsun 240Z in '88-89, and finding leaded fuel was pretty hard. Unfortunately, someone stole it, thus saving us the trouble.
This is some advanced-level silver-lining finding!

My car has been stolen, so now I don't have to find fuel for it! Bonus!

I seem to remember that the valve seats on an unleaded conversion for a 70's Aston Martin are exactly the same as the leaded originals. Make of that what you will.

How high would a ladder have to be if at the top you were able to float off into space?

35,786 km

Anything below that and you'd be travelling at less than orbital speed so would just fall back

Mmmm, so about 72 million rungs then? Might need more than one trip to B&Q.

You might struggle to find any material that could support it's own weight at that height/length, it's a problem...

Do Americans prefer European chocolate?

I was listening to a discussion on the radio this morning in which, as an aside, all the British folk were saying how much they hated American chocolate, which is what most people tend to say. As i understand it the recipe for the same bit of chocolate, such as Maltesers, is different in the UK and US.

But do American's that come over here think 'aha! Haute cuisine chocolate at it's finest. I must buy another another suitcase and smuggle as much of this black gold back to the USA as I can!' Or perhaps would they not think much of our standard chocolate like Dairy Milk, but be staggered by the greatness of our high cocoa percentage dark chocolate?

Or is it that both sides of the pond have their own acquired taste and the dislike is firmly mutual?
Good old Radio 2 taught me that the murican stuff is different to survive the higher temperatures, and that everyone seems to agree that it tastes like sick if you're not used to it.

Why is it that people with old injuries/dodgy joints/metal pins say that it hurts more when it's damp? I get maybe when it's really cold, but how can the damp affect something that's sealed inside the body. Does it do it when it's warm and damp ie humid in tropical places, or is it just that cool damp weather makes us feel the cold more so it's really just the temperature that affects it?

Make it twice the length, then it won't weigh anything silly

But the middle would need to be able to support the total weight of both halves in tension wink

If Volvo have succeeded in creating a short straight-6 (1 mm shorter than their straight-5 nerd), why hasn't anyone engineered a short straight-8? Perfectly balanced, incredibly smooth and (presumably) cheaper to make than a V8 - one cylinder bank / head / one exhaust manifold etc.

Volvo SI6 (3.2)
That's sort of what you'd have if you chopped a Bugatti W16 in half, albeit with the cylinders offset from each other rather than completely straight, but would still be a single bank and head. The SI6 isn't completely problem free IIRC, remember reading that the small amount of material between the bores caused problems if you wanted to turn the boost up too much. Although presumably not insurmountable as Polestar got 500+ bhp out of it in that S60 concept. Wonder what mods were necessary for that?

Also quoting the OP as I love cutaways!

Quoted as I'd like to know that too.

Old breaks in toes and knee definitely ache more in cold and damp. To the extent that for the knee in below zero I have to wear long undercrackers, ie thermal long john base layer, which extra claddiing can lead to betty swollocks, too much information, sorry.

Has anyone any actual experience of a car being damaged by unleaded? I've read one or two things suggesting that valve seat damage just doesn't happen

I have found as I get older knees, ankles, toes all ache more as the seasons change. Been especially bad this year to the extent treat with Brufen etc. I have put it down to hereditary arthritis..... mother is riddled with it.




Or gout...... I do like a decent bottle of port now and again!

I am having an argument with my some about London buses.

He claims I cannot use my contactless debit card for paying for me and him on the bus for the same journey?

He does not have contactless so is claiming he has to go to a ticket office to be able to get a travel card.

Surely I can pay for two people with my card?

Nope, each person has to have their own card.
