I use a new fuel, Texaco Supreme 99 Performance at 99RON with no added ethanol at the last test on it. This fuel is only at selected Texaco stations one which is 3 miles from me and ethanol free to which I add the portion of Redex when I fill up. It's especially good before the yearly engine test as its claimed to reduce emissions as well as protecting the fuel system and injectors also cleaning up burnt deposit stains in the engine where present.
That is great news abut the texaco fuel. In my area it is hard to find 93 octane ethanol free. Boat marinas sell it but even then the higher octane is hard to find at them.
