Lighten up! We have a "Board Of Health" too but that still doesnt assure food safety or quality either. Do you really believe what the Trade Commision or what the President tells you??? Those are just Safety Stops. Thats it! As far as running premium is concerned, an Engineer on another site said that premium is good for driving up in the mountains where the air is thinner and if your running an agressive injector cleaner through the engine to clean it that it will help allot. Thats it. Its back to runing 87 oct for me and jerking the injectors every 20 to 30,000 miles for an ultrasonic cleaning. PS My Speedway Rewards card pays for most of my personal gas anyway because I re-fuel all the work trucks at 200 gals a week. Case closed.
