HI, I have bought a 2007 Nissan Murano and was wondering if you can help me figure out what wrong with it. I put Berryman b-12 chemtool in a full tank on Wednesday this week. Thursday morning before heading to Oklahoma City we put $13 in the tank so we have enough get there and back on. Before leaving Oklahoma City we put $12 more in the tank so we wouldn't run out before getting home. Got back to Hugo, Ok that evening took the kids over dollar general and came back home. This morning I went to start the car. It started but wouldn't stay running. We're thinking maybe there is some water in the fuel tank but now not too sure. Put $10 in the tank thinking maybe I was out of gas went to the bank and got stranded. Same thing it would start but would not stay running. Please help
