Hello everyone. I own a 1998 Mercedes E300 Turbodiesel with 71,000 miles. I have always used the Texaco station down the street to refuel (45 Cetane-low sulfur 500 ppm). Recently, the station manager informed me that they would only be supplying ultra-low sulfur fuel (15 ppm). Is the new ultra-low sulfur fuel OK for my 1998 TD? Thanks!
