Super Unleaded NC500

[shed driver]

My 1973 P5B coupe seems like an ideal (if expensive) car to undertake the NC500 in May next year.

I'm wondering if E5 97+ RON is widely available. My useful range is about 200 miles per tank.

Any hints or tips, obviously I'll carry a few litres extra in the boot, but I'd rather rely on frequent fill ups.

When I did it years ago the organiser planned out the stops and we were generally OK for super. No idea where those stops were now I'm afraid! A few people brought octane booster just in case. Better option than carrying litres of fuel I'd have thought.

If you download the app 'Petrol Map' and register with them, you can search any geographical area for a specific fuel, and it gives you current prices too.

Did it earlier this month, biggest stretch between thurso and lochinver, you should make it fine. Can't u take bottle of additive as backup?

Super is available in Ullapool.

I don't particularly want to be putting E10 in, even if I use an octane additive.

I've been looking at it with a need to 99RON.

Fairly sure I've come to the conclusion that it's gonna be some cans on the roof to make it round.

My son and I did a fair chunk of the NC500 in early October. From our trip last year, we knew that super-unleaded wouldn't be available everywhere, so we took three cans of Wynn's octane booster.

We used eight tanks of fuel in six days. Three fill-ups (about 150 litres) were for 95 RON plus the octane booster.

My car will run on 95 RON, but it doesn't like high load. I imagine a P6 wouldn't take too kindly to having lots of E10 through its fuel lines, unless you've had everything converted. I rather doubt you'll be able to carry enough fuel in jerry cans to cover for the gaps in 99 RON availability

PS - I was getting about 20mpg, but I doubt a P6 (presumably the V8?) would get far into double figures on some of the NC500 roads
