• Gasoline with STP Additives

STP Promotional itemsWhy?

Marathon wants to be your brand of choice. Marathon's partnership with STP Additives brings a distinct identity to Marathon’s core Branded product.


The STP brand reputation has been built over nearly 50 years characterized by innovation, performance and great partnerships. STP has the longest running sponsorship in motor sports history and, in fact, in any professional sport. NASCAR fans have seen the STP #43 car on tracks around the country for the past 34 years. The legacy of STP’s affiliation with the #43 car, including its history with racing legend Richard Petty, connects with millions of racing fans.


Marathon® Gasoline with STP® Additives

Got STP? YES, We Do!

Oil companies "well know the worth of putting together the right major brands. But never before has a U.S. Oil company paired with a national additives maker to feature that firm's branded additives in all grades of gasoline – until now."          –  As noted in Oil Express (2006)

Today, Marathon and STP continue this revolutionary relationship that  differentiates Marathon from all other gasolines in its markets. In the fall of 2006, Marathon established a long-term, co-brand relationship with Armor All/STP to use STP (Scientifically Treated Petroleum) Additives, which are recognized for their ability to improve vehicle performance.
