Whilst working hard, I stumbled across this thread - an interesting read.

I done the research sone tine ago just after buying the TR.
Extensive tests were carried out by the Federation of Historic vehicle clubs (FHVC).
The top one in terms of performance and cost IMO was Castrol Valvemaster plus, one which I use all the time.

I like the sound of Toluene

Toluene eh? I know they use benzene as the anti-knock in regular unleaded, but Adding a bit of toluene should be easy enough

Christ-I never knew petrol contained toluene/benzene family chemicals. These are pretty damn toxic; if they're regarded as 'safe' then I can see why more exotic brews were banned from F1. Roll on hydrogen, on the proviso you can get a decent exhaust note burning it..

Reading this stuff, why don't more people forgoe this crap and get high octane fuel from airfields? Neighbour of mine flies a light aircraft and sometimes slurps a bit of 100 octane into his Ferrari 328. He told me you can get 120 (?) octane too but this won't help unless you tune the ignition gubbins to it. There's a TVR do in Duxford soon, and they don't run their Spitfires on super plus unleaded I can tell you.

ISTR that benzene was only introduced with unleaded petrol..

On account of this, it's said that inhaling fumes from unleaded is carcinogenic..

- provided that you've got a cat fitted, so that the carbon monoxide doesn't kill you first

Benzene is carcinogenic, but not that volatile, so you'll not get a significant dose from sniffing a bit of unleaded, and it burns up in the engine, so (unless your engine is running way too rich) there'll be sod all benzene in the exhaust gases. It was first introduced in unleaded as it has anti-knock properties to replace the lead.
