Truck Motor Oil Additives

Engine oil viscosity breaks down under extreme heat and pressure, especially in high-performance or heavy-duty applications, leading to inadequate film strength and accelerated wear. Lucas Oil Heavy Duty Oil Stabilizer thickens and stabilizes your...

Engine oil leaks drain performance and create costly maintenance headaches—Lucas Oil Engine Oil Stop Leak addresses the root cause by conditioning seals and gaskets to restore their sealing integrity. This proven additive formula works within your...

Engine oil seepage compromises performance and creates mess on your garage floor—but more importantly, it signals potential seal degradation that can worsen over time. Lucas Oil Engine Oil Stop Leak addresses minor leaks at their source by conditioning...

Engine oil oxidation and breakdown accelerate under extreme racing conditions, robbing your engine of critical protection and reducing viscosity stability. Lucas Oil H/D Oil Stabilizer combats these issues by increasing film strength and reducing wear,...

Engine oil degradation under extreme heat and load compromises protection and accelerates wear—especially critical in high-performance and heavy-duty applications. Lucas Oil Heavy Duty Oil Stabilizer reduces viscosity breakdown, extends oil film...

Engine oil degradation under extreme heat and load is a primary cause of bearing wear and premature engine failure in high-performance applications. Lucas Oil H/D Oil Stabilizer reduces viscosity breakdown and extends oil film strength, maintaining...

Engine wear is one of the most costly maintenance issues facing serious racers and high-performance enthusiasts. Antifriction Metal Conditioner reduces friction between critical moving parts, lowering operating temperatures and extending component...

Engine wear happens fast under high-performance demands—metal-to-metal friction generates heat, breaks down lubricants, and accelerates component degradation. ER Antifriction Metal Treatment conditions your engine's internal surfaces to reduce friction,...

Metal-to-metal contact generates friction and heat that degrades engine components over time—especially under racing conditions or high-load applications. Our Antifriction Metal Conditioner protects critical surfaces by creating a microscopic barrier...

Engine sludge and carbon buildup compromise fuel efficiency, throttle response, and long-term reliability. Motor Flush dissolves stubborn deposits from your intake valves, fuel injectors, and combustion chamber—restoring lost performance without...

Metal-to-metal contact inevitably generates friction and wear, compromising engine longevity and performance consistency—especially in high-RPM and forced-induction applications. ER Antifriction Metal Conditioner chemically bonds to ferrous and...
