Cars Q&A

I hv taken NEW ALTO in sept-09. Can any one suggest me, is there any possibility to FIT LPG for ALTO, if possible. Where shall I go for this LPG fitting. Shall I go 2 MARUTI Servicing point or outside mechanic. How much cost & How safe, if I fix LPG to ALTO. Out side mechanics telling that Rs.1/- per.km can get mileage on LPG, is it right ?? Kindly advise me to save expense on fuel, Im thinking 4 budget, if i need to go 500+ km journey.
