Lucas Oil 11020 Semi-Synthetic Racing ATF Type F Automatic Transmission Fluid - 1 Quart

Lucas Oil 11020 Semi-Synthetic Racing ATF Type F is a high-performance automatic transmission fluid engineered for motorsport applications and drivers who demand fast, precise gear changes. Sold in a convenient 1-quart bottle, this fluid is purpose-built to deliver where conventional ATF falls short.

Formula & Base Oils:

This fluid is blended from premium paraffinic and synthetic base oils (Groups II+ and III), combined with shear-stable synthetic polymers and viscosity modifiers. The additive package includes anti-wear agents, antioxidants, and corrosion inhibitors to protect transmission components under demanding conditions.

Key Features:

• Non-Friction Modified: Delivers a firm "sport" or "hard shift" character — ideal for racing or any application requiring fast, positive gear engagement
• Shear Stable: Resists viscosity breakdown (shear thinning) under high heat and mechanical stress
• Heat Resistant: Formulated to maintain performance under the elevated temperatures generated in racing and high-performance applications
• Oxidation Resistant: Reduces lacquer and deposit formation, extending fluid and transmission service life
• Semi-Synthetic Formula: Combines the protection of Group II+ paraffinic base oils with the performance of Group III synthetic base stocks
• Type F Specification: Meets Type F ATF requirements for compatible transmission applications

For street-driven vehicles, Lucas 11020 also delivers real-world benefits — its resistance to oxidation helps keep the transmission clean and operating efficiently over extended service intervals. Whether on the track or the street, this fluid offers a dependable, race-proven solution for performance-minded drivers.
