Mercedes Benz S-Class improvement

“Our 2012 S350 Benz (V6, 3.0 Liter diesel) has only 53,000 miles, but was blowing a lot of black exhaust smoke, and was burning oil. We bought the Diesel Performance Pack and within just a few weeks the exhaust smoke has reduced significantly, as well as the oil burning. I suspect that will continue to improve the more we drive it. Another benefit we’ve noticed is the fuel economy has gotten better by about 10%, at 90mph highway driving and we’re getting 34mpg!”
(Diesel Performance Pack contains FTC Decarbonizer, ULS Diesel Enhancer, and AW10 Antiwear)
