These day no, it won't as a rule, modern engines are built for non leaded fuels they use harder seats and valves, LPG or CNG as you call it over there, is dry which on older leaded engines tended to hammer valves, you can opt to use an upper cylinder lube additive to the petrol as well this will not hurt at all.

Try not to use CNG 100 %. Spare some time for gasoline in order to lube the valve seats.
