C 70 T5 Gas conversion?

Hello dear friends, I’m currently thinking about switching to Lpg Gas and would like to ask you about your experiences. Does this really hurt the engine? Lifetime cuts ect.? Power loss in how far… Can I travel? Cost point from the conversion? Maybe you could also recommend someone who is cheap and good at the same time. Excessive use of highway and inner city? What do you think about it? Unnecessary or advisable, I don’t drive sooo much and the work is also only 10 km away but the fuel prices and the still quite high consumption push a little the driving fun…
