As for their conventional counterparts, engines powering flex-fuel vehicles deliver optimal performance when the sensitive areas in the intake system are kept clean and free of deposits. Since no standard tests are available for evaluating the tendency of fuels to form intake valve deposi...

A 104-member consumer panel was asked to rate its willingness to pay (WTP) for plain and low-fat yogurts in 3 information conditions: tasting without information (blin...
