The "service station" closest to my office just happens to offer B20 as well as dino-Diesel. Now isn't that nice!
So I've alternated between tanks of B20 and Dino, and it seems to me that I get roughly 1.5 MPG better fuel mileage on Dino-Diesel, but the car runs smoother - considerably so - on B20.
Have any of you out there run B20 versus Dino? Do you notice the same effect or is it simply psychosomatic on my part? I like running B20 as it costs exactly the same per gallon as Dino but with only 20% concentration of Bio, I suspect that I may be imagining and convincing myself of the smoother running.
Cheers!
