cold starts punish our fuel economy. the long the engine takes to warm up the worse the economy gets. I purchase fuel from one wholesaler at 260 gal. a time. When I asked him what they do for winter fuel, I was told they only put a cold flow additive in and no #1 diesel or kerosene. I was worried about fuel economy in the summer, because I was buying the fuel mid-winter here in michigan.

well since cleaning the MPG the computer is reporting has gone up some but slowly. Another thing I noticed when mearging on to the highway to go across town is that on wide open throttle I don't notice smoke like before.
