Adm Msg - Fuel Economy with Northstar Equipped Vehicles

If a customer with a Northstar equipped vehicle inquiries about fuel economy shortly after delivery, please advise them of this information:

Cadillac vehicles equipped with the Northstar engines have very competitive fuel economy labels compared to vehicles in their class. Northstar engine vehicles rank high in their brand market segment for both city and highway fuel economy.

Northstar engine customers will experience an increase fuel economy after an initial "break in" period of over 4,000 miles. The "break in" period allows the mechanical powertrain components to work more efficiently together. Based on formal testing by the GM Certification Group, fuel economy improvements could result in as much as 3-4 miles per gallon (mpg) on some vehicles. Actual fuel economy can also be affected by traffic, weather and personal driving conditions. As a courtesy to the customer, be sure to clear out the average fuel economy data in the instrument cluster.
