Subaru engines do not like LPG, its due to the high running temps when using it.

Yeah that is true, it does have a heigher RON value but it has a lower calorific value meaning you need a lot more of it to make the same power as petrol.

So realistically if you fitted a flashtube/lube kit, you could get higher gains powerwise out of running LPG on a Subaru tuning wise? But saying that if you fitted a 100ltr tank in the boot am sure it's around 70p per ltr, if the quantity needed is more to burn, ya pockets not really any better off is it? When I had the v8 disco back in the day LPG was 38ppl so it was the equivalent of running a 2.0 petrol, think the tank was around 100ltr in that which use to return about 240-250 miles

gas doesnt like to be heated too much, it can cause pre ignition in the inlet, resulting in potential melting of the inlet manifold, ive seen this on the gas gensets i commission when the gas is too hot on intake, or the timing isnt spot on which can singe valve seats out, the result looks like cutting steel plate with oxy torch
