We used to have a Smart car, that was remapped, from memory, to a heady 80bhp.
Optimax as it was then made a huge difference to the drive of the car, to the point I wouldn't put anything else in it.
Very noticeable, and I wouldn't say I'm a driver in tune with an engine well enough to notice an extra few % power on a more 'normal' car.
On that basis, I've always put 99ron Tesco or V-Power in my Alpina, as they recommend super unleaded only, but in theory it'll retard the timing to cope with standard 97ron.
I can't feel a difference between V-Power and 99Tesco.
Merc will get standard unleaded, but I try to avoid supermarkets - that Morrisons fiasco a while back made me paranoid about poor quality fuel.
Another point is I think fuel deteriorates with age, losing it's 'rons' - so if you have a sunny-day/once a week/month car, keep it very low on petrol and top up frequently, or use high grade fuel that may stay at or above 97ron for longer.
Yeah boy you in tune... grand commenting
