Formula 1 grand prix cars use fully synthetic engine oil supplied by official lubricant partners, with the exact viscosity and formulation chosen to suit the power unit and climate; the FIA regulates these specifications, and teams negotiate with dedicated oil partners each season.
How oil is specified in Formula 1
In Formula 1, the engine oil is a high-performance, fully synthetic lubricant designed for extreme temperatures, high RPMs, and the precise demands of a racing power unit. The oil must help lubricate bearings, dissipate heat, and preserve seals under gruelling race conditions. The exact viscosity and additive package are chosen by the engine partner in collaboration with the official oil supplier and must be approved by the FIA for the season. These choices can vary, with viscosity ranges typically spanning from very low to moderate values depending on the engine design and climate.
Who decides the oil specification
The specification is a collaborative process among the FIA, the engine manufacturer, and the team's official lubricant partner. Each season teams partner with a lubricants supplier who can deliver a bespoke formulation tuned to their power unit. The aim is to maximize performance and reliability across diverse circuits and weather conditions, while complying with regulatory limits on testing and usage.
Oil on race day: usage and management
During a grand prix weekend, teams rely on a carefully engineered oil system designed to withstand practice, qualifying, and the race distance. The oil is part of a sealed, monitored system, and samples may be collected for regulatory compliance and performance analysis. The oil used is not consumer-grade but a purpose-built racing lubricant with additives engineered to reduce wear, control deposits, and manage high-temperature operation.
Big-picture context
Beyond peak performance, top-tier motorsport oil programs emphasize reliability, consistency, and sustainability. Suppliers invest in cleaner formulations, improved efficiency, and recycling initiatives to minimize waste. The result is a high-performance lubricant that meets stringent regulatory standards and supporting environmental goals while catering to the specific needs of each season’s power unit.
Summary
In short, grand prix oil is a fully synthetic, high-performance lubricant tailored to the racing engine and season, selected through a collaborative process involving the FIA, engine makers, and official lubricant partners. The exact viscosity and formulation vary by team and year, reflecting the evolving demands of Formula 1 technology and regulations.
