Spring Cleaning Starts Early with Gasoline that Cleans and Protects

HOUSTON, March 6 /PRNewswire/ -- This morning at Shell stations across the U.S., consumers received a free fill-up with Shell Nitrogen Enriched Gasolines, a new fuel containing a unique, patented cleaning system designed to seek and destroy engine "gunk" (carbon deposits) in all three grades of gasoline. To celebrate the debut of the new fuel, Shell held seven simultaneous events - Shell Nitrogen Enriched Gasoline Spring Clean-up Giveaways - where free fuel was available from 7 a.m. - 9 a.m. to drivers.

Consumers lined up in their vehicles for an opportunity to try the new fuel (at no cost) in top commuter markets, including New York City, Los Angeles, Washington (District of Columbia), Seattle, Houston, Jacksonville, and Cincinnati. Throughout the week of March 2, local radio stations hinted to participating Shell gasoline stations in their respective regions. This morning, on-air personalities finally directed listeners to a selected Shell gasoline station in their area, and throngs of consumers followed.

"With Spring approaching, people sometimes forget that their vehicle engines need a 'spring clean-up' too," said Karen Wildman, Shell U.S. brand and communications manager. "These gasoline giveaways are a great way to introduce the new Shell Nitrogen Enriched Gasolines to drivers and to showcase how the gasolines clean and protect critical engine parts."

NITROGEN ENRICHED FUEL SPARKS SPRING CLEAN-UP

With spring on its way, there's no better time to get a head start on cleaning vehicle engines with Shell Nitrogen Enriched Gasolines. Nitrogen is a key ingredient of the gasoline's active cleaning molecule, which is significantly more stable at higher temperatures common in modern engines, such as direct fuel-injection engines. The increased stability ensures that the molecule can work under much tougher engine conditions by resisting thermal breakdown better than conventional cleaning additives.

Shell developed the new fuel with the consumer in mind, knowing that in today's challenging economy consumers are looking to preserve one of their largest investments - their vehicles. They also are looking to get the most out of every drop of gasoline. Shell worked very closely with automotive manufacturers to gain insight into current and future engine technologies. These insights along with fuels technology leadership and a strong research and development program help Shell continually improve its products.

Additionally, the new formula is proven to prevent build-up of gunk more effectively than gasolines containing only the minimum amount of cleaning agents as required by the EPA. The new formula is certified to meet and exceed TOP TIER Gasoline Detergent standards - voluntary standards designated by some of the world's top automakers (Audi, BMW, GM, Honda, Toyota, Volkswagen) to try to raise the bar on fuel quality beyond minimum government criteria.

Shell is supporting the launch of Nitrogen Enriched Gasolines with a national marketing campaign, including national TV, radio and online advertising, as well as point-of-purchase marketing at Shell-branded stations. The new campaign builds on the current "Passionate Experts" platform, focusing on the company's commitment to fuel quality and passion for developing innovative new products, helping consumers get the most out of every drop.
