I'm going to ask a very stupid question but....
Over here the highest octane petrol is rated at just 93 (probably a bit more since it's now mixed with ethanol). That would mean that high compression cars (compression ratio above 11:1) such as the BMW M5 or the Audi RS4 wouldn't run very smoothly over here. Does that mean that these cars would run better on LPG?
BTW. Most of the cabs here have already been converted to LPG. A cab driver once explained me that he was saving a bundle. However, he did a little demonstration and when going uphill there was significant power loss with LPG. With full load and a steep climb he had to switch back to petrol.
