I had gotten gas on the rez by my house a few times. I notices a major difference in the performance level of my car and my gas mileage dropped. Normally if I put in $10 in gas, I can get to GCC and back and have like a gallon left over, I got rez gas and ran out like 5 miles from my house. Thought maybe it was a fluke, got it again another time, and ran out again, thank god I had some “emergency fuel” in my car at the time. I also lose a lot of torque on rez gas, it feels like I’m riding the brake when I hit the gas and there is a lot of hesitation. Also, my rpm’s at idle are all weird. instead of a steady 500 rpm idle, it wavers from 350-600 and runs really shitty. Dunno why or what they put in it but I won’t get it there anymore. Had to put in a bunch of dry gas and shit to get the car running half way decent again.
