This has been done a few times before as you can imagine but cars designed to run on 98/99 do slightly worse economy and performance figures when run on lower octane petrol.

You can do it if necessary but you should revert to full fat petrol when able.

Saying that, if you take a step back, why buy a car of that value and then skimp on shyte fuel?
