HOUSTON, Nov, 21, 2013 /PRNewswire/ -- Since early October, motorists from across the country have shared with Shell, the no. 1 selling brand of gasoline in the U.S., the moments, locations, people and sights that make up their formula for driving excitement in the Shell V-Power® " Formula for Excitement" Contest. From images of loved ones, pets, dream cars, and winding mountainous roads, Shell has seen that every motorist's formula for an exciting drive is unique and creative. Shell also knows that the foundation of every exciting drive is a vehicle, which is why Shell has been providing motorists with technically advanced fuels for improved vehicle performance. "An exciting drive is only possible when a vehicle performs at its best. That's why all of the submitted Formula's for Excitement start with Shell V-Power Premium Gasoline," said Elizabeth Hudson, fuel category manager at Shell Oil Products US. "Shell is proud to be a part of these formulas and that is why we strive to create the products like Shell V-Power Premium Gasoline that helps keep drivers' engines performing at their very best." From now until November 25, consumers can still share the photos that best represent what makes an exciting driving experience for them at www.shell.us/Formula for a chance to win a once-in-a-lifetime three-day driving experience. To date, seven consumers have been named Weekly Winners on the Shell Facebook page and received $250 in Shell V-Power Gift Cards, and there is still one chance to win. From December 9 to December 19, consumers will have a chance to vote on the formulas of the eight Weekly Winners to select the one formula they feel best represents the excitement of driving and deserves to be named the Grand Prize winner. The entry that receives the most consumer votes during this period will be named the Grand Prize winner. The Grand Prize winner and a guest will travel to Chicago, Ill., where they will enjoy the thrill of driving a NASCAR stock car with the Richard Petty Driving Experience. They'll then travel from Chicago to Indianapolis, Ind., to attend the "Greatest Spectacle in Racing," the Indy500. In addition, the Grand Prize winner will also receive a year's worth* of Shell V-Power Premium Gasoline. Shell V-Power® Premium Gasoline actively cleans for better performance. It removes an average of 60 percent of harmful intake valve deposits left behind by low quality premium gasoline, and starts with the very first tank. It's Ferrari's choice for improved performance.
