I buy B20 biodiesel in part because it minimizes the diesel exhaust "stink" that my wife doesn't like. As I'm fond of her (after 40 years), I try to do things that make her happy.

Unfortunately, in our little slice of heaven we are down to one B20 supplier. Should it go away, we'll have to run straight D2. I can add a lubricity additive but I doubt it will modify the smell. Any suggestions?
