New Formulation Builds on Decades of Fuels Innovation and Proven Performance

Chevron U.S.A. Inc., a subsidiary of Chevron Corporation (NYSE: CVX), today announced the introduction of next-generation Techron®, a reformulated version of its proprietary gasoline additive designed to provide greater protection for engines from harmful deposits caused by lower quality fuels, supporting long-term engine performance.

Techron has been trusted by drivers for decades as part of Chevron- and Texaco-branded gasolines. The latest reformulation reflects Chevron’s continued investment in fuel quality and scientific testing to help ensure its fuels meet the needs of today’s engines and driving conditions.

“Fuel technology never stands still,” said Andy Walz, president, Chevron Downstream, Midstream and Chemicals. “This new Techron formulation builds on what drivers already expect from our branded fuels – clean engines, reliable performance and confidence at the pump – while reinforcing our continued focus on science‑based innovation.”

Tested, validated performance

All claims for next‑generation Techron are supported by rigorous testing conducted by Chevron scientists, chemists and engineers. The formulation was evaluated through a comprehensive validation process that includes laboratory testing, engine studies and benchmarking against competitive fuels.

When used consistently, fuels with next‑generation Techron are formulated to clean up to 100 percent of harmful deposits left by lower quality fuels.* This deposit clean-up helps improve engine efficiency and performance.

Science at work in every gallon

Techron is a proprietary Chevron fuel additive developed through decades of research and ongoing improvement. The updated formulation reflects Chevron’s dedication to high fuel-quality standards beyond industry requirements and helps drivers feel confident in the fuel they choose.

Next‑generation Techron is now available across all grades at U.S. Chevron and Texaco stations.
