Hello. I wanted to tell you how impressed I am with your product. I am a police officer with a small municipality in northwest Missouri. I am assigned a 2006 Crown Victoria. I take very good care of my personal vehicles and treat my patrol car in the same way. Regardless, police cars are driven harder and longer than any car out there. I was told about BG Products by two friends who are mechanics.They recommend BG 44K®. I was a skeptic to say the least as I have tried other products with none of the results the manufacturer claims. Bottom line: BG 44K® is the real deal. I have experienced better acceleration and fuel mileage. Thank you again for an amazing product.
