quote: Yup, he is right, in my audio a3 1.8 turbo i have a digital dash which tells me how many miles i can do on the petrol, full tank of optimax - 455 miles, full tank of normal 400 miles, both figures i get after starting the car once filled and leaving it for 2 mins or so to work it out | |

PanaceA, I gotta disagree wi your economy figures. I get consistently more mpg with 97 as opposed to 95. | |

i have noticed that my 1.2 not only idles better, but is improved throughout the rev range, more noticeable when cold, also i have found it more economical after 3 tanks | |

97 RON is the octane level of the petrol. The higher it is the more aggressivly it burns. Standard petrol is 95 RON but you can buy 97 and 98 RON from many petrol stations. The 97 and 98 RON petrol is sold mainly for performance Japenese cars like Imprezas. In such a car the engine would perform a hell of alot better with the higher octane petrol. In Japan almost all petrol is 100 RON so when you buy a Jap import car you HAVE to run it on high octane petrol such as 98 RON or performance will be greatly reduced. Rally cars also use high octane fuel, WRC fuel is 102 RON! | |

I get more mpg in my 99 sport. Difficult to say if performance is better, but i wouldn't say it was worse. My car has an automatic knock sensor, you might need to turn over a plug under your bonnet to adjust your spark timing. | |

Would i actually see a drop in performance by putting 97 RON petrol into my car or would it be exactly the same performance but just cost me a bit more? |
