Hi if i was buying petrol from the supermarket after a while of using it i know my car starts to pinker a little but ive stopped using the supermarket and i only use Shell but not the Optimax as i think its much cheaper to go to a motor factors and just buy some petrol treatment for the engine.Thats all that is different between Normal Unleaded and Optimax at shell.

But i have to say it does not bother some cars at all but i do notice a difference and other people will not you are on your own but try and see how you get on i hope this helps
Currently in Donald's garage:
2005 Mercedes Benz C200 Classic SE Kompresser & 1998 Fiat Cinquecento Fire Sporting,some may say i could do far better?,i say i could do far worse.
