i was referring to oil seep from the valve seals to the combustion chamber. the valve seals weared down faster with the lpg as compared with premium. but then found that drivers who used unleaded gave faster wear down compared with the premium also. but not as fast as lpg wears down with the unleaded. so back to when we ran our taxis with gas, i had stickers put premium only as it gave out the best result. thats mostly speaking for a 2E engine.
