In the current energy-efficient climate, I wouldn't put "fuel up" in any headline that is meant to encourage people to buy a vehicle.
DCrux is right on this. Your headline should be a strong call to action -- the action being that you want the reader to read the rest of the press release.
Start it out with an active verb. "Kick-start Your Day with a New Turn-key Harley" "Drive into a brand new ride: Harley Davidson grand opening (in name of city or date)".
Or pull from your content to see what's special about the grand-opening. Are they giving away a bike? Will they have special exhibitions?
The bottom line is to get your reader involved at the top of the page.
