Is there a petrol station near by or do i have take some with me.

The nearest off site is about 2 miles.
But they have a pump on site which is usually working
CU there

I've been to Mallory twice. Once the in-circuit station was working and once it wasn't. The only sell 99 RON (from memory) and it aint cheap.

I usually plan to fill up just before arriving at the circuit plus I take a jerry can with me. I go out at lunch time to top up if I think I need it.
