only have my RS200 a week or so, did my first mpg calculation last night after a fill up: 20mpg on a mixture of back roads, city, and late night 'spirited' motorway driving. on crappy 95 octane petrol
How does that stand up? filled with Shell V Power last night will see if that makes a difference.
Whatever just buy one, its a small price to pay for such a cracking car! :)
If your changing between standard unleaded and v- power make sure you reset the ecu, it helps the ecu adjust to thge different fuel quicker. i get about an extra 50 km from a tank of vpower
