Just found out last tuesday that the D Avenue BP fuel plaza north of Kalamazoo just put in a b-20 pump. It's 20% bio - 80% Amoco PREMIER. Fuel from this pump has been lab tested as well and came back VERY clean. MUCH higher than average. Right now it's selling for 2.45/gal.
They are doing a market test with it right now through fall to see if it's worth it for them to keep it. If you use it, drop Ridderman Oil a line and let them know!
