MichaelG Posted April 6, 2005 Share Posted April 6, 2005 If in doubt, stick to Optimax, it seems to have the majority backing. But bear in mind that all petrol will degrade in octane quality over a period of time in your tank. Michael Link to comment Share on other sites More sharing options...
Markie Posted April 7, 2005 Share Posted April 7, 2005 Could be you also need to reset ECU for the car to learn new mixtures and all with the new type of more explosive fuel.. NEWBI to leaning techie stuff though, so take my advice with a pinch of salt mate.. Someone who knows more will hopefully to able to help you more.
