From the manufacturer

About Us

In October 1954, three businessmen with a mere 3,000 dollars in start-up capital introduced the first STP product in St. Joseph, MO. STP, began with one product — STP Oil Treatment. It helped automobile motor oil resist thinning at high temperatures and pressures.

Product Description

This two-in-one formula boosts octane and cleans the fuel intake system to restore lost performance.
