Is 10bhp (in a diesel!) really any difference at all? It's madness I tells ye
Well, I think that settles it for me

When I filled up with the super diesel I had the fuel reserve message on. I thought the F30 diesel had a 57 litre tank but the last time I only managed to squeeze 49.4 litres in before the clunk. The last time it was 153.9 per litre compared to 143.9 for regular diesel. Just under 5 extra.

So far I haven't noticed any great increase in mpg, it may be 1-2mpg higher but seeing as I've paid the extra 5 I don't think I've got a good return there. The car does seem to be smoother now but maybe that's just the placebo effect or my wallet trying to convince me it wasn't all bad

I don't mind paying a couple of pence per litre more than a supermarket but an extra 10p on top of that for a negligible increase may be pushing things a bit far. All those extra fivers are better spent elsewhere
