conoco bad gas monument, Colorado
Filled up with 91 octane premium, July 4th in a 1964 1/2 Mustang 289 4V. All signs of bad gas. Hesitation, stalling, poor starting and idling. Car has has points, condenser, plugs, and fuel filter replaced. Sample of gas taken by mechanic and 2 bottles of Heet have been added. Still runs poorly. Will never go to another Conoco station again. A classic car restorer told me I am the 4th person he knows that has had a similar experience with Conoco gas.
