Hello, I am interested in buying a Cadillac Escalade from 2005 with the 6.0 machine (not the 6.2 machine). The vehicle has an already installed LPG system. Now I have already read in the net a little bit about the vehicle and have read several times that the engine is not permanently gas-resistant. I would therefore be interested to what extent this is expressed then? To what extent the gas operation damages the engine and what exactly does this result at some point? What would a repair be cost-effective? is the engine even even repairable? If someone has personal experiences in the matter I am of course happy to hear about it already thank you in advance for your answers, greeting, Robert
