E10 petrol statement from Caterham

https://www.caterhamcars.com/en/latest/can-i-use-e10-petrol-in-my-caterham

TL;DR:

All Ford and Suzuki-powered Caterhams since 2006 are compatible with E10, but you might want to fill up with E5 before storing for winter.

All other Rover, Vauxhall or Ford x/flow Caterhams should use E5.

Perhaps we should make this sticky?

Right now, if you want E0 (and you live in the right part of the country), Esso Synergy Supreme+ 99 is ethanol free:

So that might be an even better winter storage fuel.

I use Supreme+ 99 in my Crossflow. They also have a useful phone app for paying and locating stations

Thanks for posting. It's helpful to have the factory's advice.

In addition, and as in the many other times that this has been discussed:

1 Sevens last a long time. Rubber and plastic components in the fuel system might not last as long. Think of them as consumables.

2 Materials approved for use in vehicles have been tested for resistance to ethanol for several decades. But other materials might be used in Sevens in modifications, upgrades and eg DIY gaskets.

I use Supreme+ 99 in my Crossflow.

I have to admit I use it in my 310R too. For a low mileage keeper I think it makes sense to use fuel that will look after the engine. If not for the not for the zero ethanol content, then for the detergent additives.

I'll be using Super UL in the Seven, 911 and Briggs & Stratton! That said my 2003 Porsche seems ok on E10 according to the Gov website!

Makes sense with small (power equipment) engines, particularly before winter.  They don't have the flow rate required to clear small amounts of water from the float bowl.
