I run B99. Car runs more quietly. No smoke from exhaust except at first startup in cold weather. It's more expensive, but I don't mind. I like how it makes my car run. I don't drive that often or that far anyway. Haven't had to replace any of the 5/16" lines yet. My 1/8" ID return lines which were old already did almost immediately start weeping with the B99. I'm running the Tygon "weed-eater" lines now and love how they are working and the price.
B5 and B20 are also available around here for the exact same price as D2 if you find the right station.
