I know because a friend of my was one of the test pilots with a Grand Cherokee 1998 mod v8 5.9 (direct injection lpg ) That model wouldn't run on LPG without giving error messages from the computer but they fix it. Jeep Dealer strongly didn't advised LPG for that model. board computer didn't accept it.
