Priority on Performance — Tough, Tested & Proven

Universal Lubricants is so confident in our oil that we decided to put our product, Eco Ultra, to the test. A grueling 150,000-mile taxi cab field test in Las Vegas confirmed that Eco Ultra is a powerful choice for proven engine protection. Even through stop-and-go traffic with frequent idiling - in the relentless waves of summer heat and bitter winter lows - Eco Ultra delivered sufficient lubrication for sustained fuel economy.
