E10 Fuel Compatibility for Speed Six
Discussion
V6 Pushfit said:
Will the speed six run on E10? There’s no TVR listing on the Govt website however looking at other makes it seems that some other performance-type cars are ok in it.
I've used the 102 Octane on German motorway services....which I think is/was a 10% alcohol based fuel.The Tuscan ran fine - maybe a few more pops on the overrun?

E10 should be fine if you are running the car regularly. What you don't want to do is fill it to the brim with E10 (or E5 really) before storing it away for the winter. Ethanol is gygroscopic so it absorbs water from the atmosphere. Over time, water and ethanol form a mix denser than petrol, and in a process known technically as “phase separation”, sinks to the bottom of the tank and causes issues
The availability of ethanol-free high grade fuel was discussed here :

Esso already sells ethanol-free 99 octane at many of their stations, and is aiming to have it available at all of their outlets by early 2022. Of course, it will be more expensive than the standard stuff, but a price worth paying to avoid the pitfalls.

Was reading over the weekend of problems arising now with PHEVs that are being used only on electric (typically under 30 miles/day) and consequently this s
te e5 fuel 'going off' in the tank as a result of the lack of use.
Same applies to any underused ICE though, not just cars but esp motorbikes over the winter, lawnmowers and other garden machinery.

The Esso tip is a good one. A few pence on a litre, on a car in which I do less than 5,000 miles a year, is far less important than not buggering up (technical term) God knows what in the engine/fuel systems.
I will pedal down to my local Esso later today and report back on prices compared to the Shell opposite.

I paid £1.52 a litre last week for Diesel for the ‘works bus’. I will pedal down to my local Esso later today and report back on prices compared to the Shell opposite.
E10 has less energy per unit volume, therefore I'd expect the Speed Six to run weak.Hence more pops and bangs on the overun as someone mentioned.
Burned pistons,blow ups,etc all quite possible on E10 ,weak mixture equals too much heat , especially under high load conditions.
Modern cars have sophisticated engine management which will add more fuel volume, if running E10.MPG will go down and fuel consumption increase on E10, for modern cars.Did Boris tell everyone who uses E10 in a compatible vehicle,that they will need to buy more fuel for a given distance travelled,relative to E5??????
Use Esso Supreme 99+ unleaded, ethanol free in the southeast and midlands.Its marked as E5, because it can legally contain up to 5 % ethanol, but doesn't have any,if supplied by an Esso owned terminal.

No it is not. Here in Germany 98 Octane fuel is not available as E10 fuel but limited to 5% (E5). Fuel companies state that 100/102 Octane fuel is without or a with very limited portion of Ethanol (eg Shell: 0.7%). A bit late to the party with this, so I apologise in advance.
I was watching one of Harry Metcalfes ‘Harry’s Garage’ on YouTube and I feel sure he made mention of some fuel you can buy for when you are laying up a vehicle over winter..
That was the up side.
The downside was that iirc it cost £3/litre, but prevents all the issues that normal fuel causes over periods of inactivity.
Hope this is of use...

That would be a stunning post if you also named the type of fuel. I was watching one of Harry Metcalfes ‘Harry’s Garage’ on YouTube and I feel sure he made mention of some fuel you can buy for when you are laying up a vehicle over winter..

99 Ron unleaded ,ethanol free " storage", fuel is available from Anglo-American oil Company info@aaoli.co.uk
However,it is difficult to see how this is any different from Esso Supreme 99 plus unleaded ,which is ethanol free ( though marked E5 for legal reasons), in the Southeast and Midlands of England.
Apparently a 5 star leaded version will be available from aaoil in due course for older carburettor vehicles.
On a separate point,having driven our Saxo vtr over a thousand miles of mainly motorway this Christmas,we have recorded 53 mpg on Tesco 99 superunleaded ( which is up to 5 % ethanol in the Northwest,and Scotland, where we filled up) we only ever got 43/44 mpg on the old E5 ordinary unleaded!
E10 would no doubt give less mpg than the old 95 RON?
So,using Tesco 99 superunleaded is actually cheaper than ordinary unleaded for motorway use !

That’s brilliant thanks, I’ll look into it I’ve changed 4 sets of fuel hoses for Gates Barricade now, just want avoid and regular draining down.
