I have a 2008 Jeep jku Sahara and if I don't run premium gas my check engine light comes on I had it tested every time it does it and the only time it comes on is when I run anything other than premium gas it has the stock 3.8 in it and if I run something other than premium it throws an O2 sensor code so all I run is premium Now anyone else have a similar problem?
