Fuel grade

What do you guys run your cars on, high octane/optimax, or just normal unleaded.

The factory position is that the car is mapped for regular unleaded and the map will only adjust for this should you use another grade. Some on here swear by Optimax, due to it's supposed cleaning powers though so take your pick. I use regular and then Optimax for "spirited" runs and track stuff.

Optimax works out at ~£200 per 10,000 miles difference. Why skimp?

I use premium fuel only.
