Hi All
You can run on lpg right away from start up However if your heavy on the foot you will draw to much lpg through the vaporiser and it will freeze before the hot water runs through it too vapourize and it is advisable to lubricate your petrol injectors to stop them sticking That being i always start all my cars on lpg and only use petrol should i ever run out of petrol without any worrys i have run both single point closed loop and the early and the latter m/p injection systems they all have there benifits if fitted correct and correctly used
