Q

I'M THINKING of converting my V6 Holden VT Commodore Series I to gas, but I'm getting conflicting advice. Dealers say it can cause backfiring and engine damage, but converters say there is no problem. The car has done 140,000km and I do about 18,000km a year.

THE dealers will always advise against converting because they don't want any comebacks should something go wrong. They have no control over the expertise of the person doing the conversion or the quality of the work. The converters have heaps of experience and will say cars such as yours can be done without a problem. In this case follow their advice, but ensure it's done by a competent converter.

  • Vt V6 engines may get premature valve guide wear on LPG and backfiring may happen due to large volume of gas after the throttle body when too much throttle applied at low speed
