G'day All, Recently bought a 2000 ACA21R automatic 5 door Edge (1AZ-FE engine). I have been running it on regular unleaded since I bought it (no ethanol) but have wondering about using "premium" unleaded. Thinking about trialling premium for a couple of months to compare fuel cost vs economy vs performance. Has anyone else done this and found one fuel better than the other? Obviously any improvement in performance will be a subjective opinion, but does anyone have any comparitive fuel economy figures with regular and premium unleaded? Thanks, Kirk
