New Petrol Variant
Discussion
Hi All. Read an article the other day that a new petrol variant E10 is being released over and above the current E5 - 10% ethanol v 5%. Although the E5 will still be available it will be a premium cost over the E10.
A link to Gov website to check if your car can take E10 proves useless. TVR not listed as a manufacturer in the drop down and when you click the if not listed option it says - 'Contact Manufacturer' (nope, can't do that) or 'Check inside filler cap' (obviously never seen a T350
).
Anyone any the wiser? Thanks.

Thanks for the replies.
Its new for the UK from Sep 21 and there are internet articles which say which cars can and cannot use E10 and there are a few specific models of mainstream manufacturers listed as not being unable to - including Lotus, Lexus, 2 x Merc models, Ford, Carrera GT....Assuming the articles are accurate.
UK Gov website only states those unable to as:
'The following vehicles, however, may not be compatible with E10 fuel:
- classic, cherished and older vehicles
- some specific models, particularly those from the early 2000s'
Pretty sure TVRs would be associated with these categories.
Hence my question. Obviously, I'll just stick with E5. Thanks anyways.

The standard here is E10 which is in all petrol sold (with a few exceptions). All light vehicles after 2001 can use E15 and the latest flex fuel engines use E85.
It's nothing new.
Not sure how US fuel standards are relevant? TVR’s weren’t built with any consideration for the US market or ‘E’ fuels, let alone the US “flex fuel” standard.It's nothing new.
Anyway, the engine will be fine with “E” fuels. What can become an issue is it rotting the fuel hoses. However most have been replaced by now as UK fuels have have had ethanol in them for a while, which is why rotting original fuel hoses is a common problem. There’s unlikely to be many, if any, around these days with the original hoses though.

Alcohol (methanol in early days - ethanol now) has been used in internal combustion engines for at least 100 years.....So nothing too contentious there?
The engines of a century ago whilst advanced for their day, were not in the same league as current engines. Alcohol does not affect the basic running of a spark ignition engine, the oxygen part of the fuel improves the burn in the cylinder.
The unwanted side effects are the fact that ethanol is hygroscopic, and by attracting water can lead to quicker rusting of the fuel system. Secondly, it also degrades/softens plastic/rubber components in the fuel system.
The above side effects are easily sorted - A) by driving the car! thereby preventing fuel to languish in your steel tank! and B), getting the fuel system checked regularly for any signs of component seal breakdown.....But that is what most of us owners of our lovely cars do anyway. Right?

The reason why your TVR will not run properly on 10% ethanol petrol,is that it will run weak, E10 fuel needs the engine to consume more volume for a given power produced.This is because each litre of E10 contains less energy than E5 or non- ethanol petrol.
" Modern ", cars have some sort of feedback system which allows the volume of fuel injected to be increased when you fill up with E10.This will increase fuel consumption,but your engine will not be damaged by a weak mixture.
On carburettor cars,you can rejet it,on our cars with fuel injection,you could have a rolling road remap on E10??
But,once you set it up for E10, it will run rich on E5!!
