Was reading the motoring section of Inquirer (last Friday yata). There was a write up about a company that supposedly specializes in converting Euro cars such as benz and BMWs to lpg.

Company name is Electromex tel# 531-6782 and 535-9069

whats your consumptions before and afer?
As per the previous posts, expect your consumption to increase by around 15 to 20%. But since lpg is cheaper you still save on cost per km.
