and don't drive around with a boot full of junk, that helps

Diesel doesn't burn? Funny, I wonder why my engine gets hot?

Because the diesel gets compressed and then explodes rather than burning like petrol does.

they tend to be promoted in spring, when MPG improves due to the reduction in very cold starts.

I'll think you find that 'explosion' is the diesel combusting with air in the cylinder i.e burning. Hence the term 'Oil Burner' for a diesel car.

they make me laugh. About the only place I'd fix a magnet to on mine is round the oil filter, to trap any swarf.

Of course, they "may" be a benefit if you have an old rusty fuel tank...if they stop the rust getting any further up the pipe.

Obviously there is no way to reliably test if it saves me any fuel at all

Actually there is, but it's unlikely that any householder has the means or inclination to do so (even if we put aside the fact there isn't a shred of evidence or even a plausible theory for it working).

So I just leave it on just in case

Which is easier than admitting you've been conned and throwing it in the bin I suppose.

I like snake oil my car runs great on it

Must try magnets, I tried go faster stripes and can get a few mph extra when I put my foot down

Both diesel and petrol work in almost the same way only diesel is more combustable under pressure than petrol, hence in a petrol you need a certain little spark to get things kicking off whereas in the diesel its compression only. Both work by combining an air fuel mix then igniting in different ways under compression.

The only way to get energy from fuel is to burn it and of course you never get more back than you put it, or anywhere close...

Ah right, so petrol engined cars aren't powered by explosions?

That's a new one to me.
