Maxima Performance 10W-40 Mineral Engine Oil – 1 Quart | 2X Zinc | Race & Hot Rod Formula

Protect your race engine, hot rod, or high-performance build with Maxima Performance 10W-40 Mineral Engine Oil — a purpose-formulated mineral-based engine oil engineered specifically for race and hot rod applications. Featuring Maxima’s 2X Zinc system for elevated ZDDP anti-wear protection at any temperature, high-quality mineral base oils, and an advanced proprietary additive system, this 10W-40 delivers world-class durability through effective ring seal, optimum engine cleanliness, and resistance to the viscosity breakdown caused by fuel dilution. The right oil for high-output, high-temperature engine applications where conventional motor oils fall short.

Key Features:

• 2X Zinc system — double the zinc (ZDDP) anti-wear additive concentration for superior protection of camshafts, lifters, and high-load valve train components at any operating temperature
• Mineral oil base — high-quality mineral base oils preferred for race and hot rod applications where controlled friction and high ZDDP compatibility are priorities
• Race and hot rod formula — extensively developed formulation engineered for the extreme demands of race engines and high-performance street builds
• Effective ring seal — formulation promotes and maintains proper piston ring seal for maximum compression and oil control
• Optimum engine cleanliness — advanced additive system resists sludge and deposit formation to keep oil passages and engine internals clean
• Fuel dilution resistance — resists viscosity breakdown caused by fuel dilution — critical for race engines where fuel contamination of the oil is a common concern
• 10W-40 viscosity — wide viscosity range providing cold-start flow and robust film strength at high operating temperatures

Performance Benefits:

• 2X Zinc Anti-Wear Protection: Maxima’s 2X Zinc system provides double the ZDDP concentration of standard motor oils — creating a robust sacrificial anti-wear film on camshaft lobes, lifter faces, and high-load valve train components that is critical for flat tappet camshaft applications and high-performance builds where contact pressures exceed the protection capability of standard oils
• Ring Seal Maintenance: The formulation’s ring seal properties maintain proper piston ring contact with the cylinder wall, preserving compression, minimizing blow-by, and controlling oil consumption — essential for race engines where compression consistency directly affects power output
• Fuel Dilution Resistance: Race engines are particularly susceptible to fuel contamination of the oil from rich running conditions, cold starts, and blow-by — Maxima’s formulation resists the viscosity breakdown that fuel dilution causes, maintaining protective film strength even when fuel contamination is present
• High-Temperature Stability: Engineered for the sustained high operating temperatures of race and hot rod applications where conventional oils thin out and lose protective film strength
• Engine Cleanliness: Advanced additive system resists sludge and deposit formation in high-temperature, high-RPM conditions where oil degradation is accelerated

Specifications:

• Brand: Maxima Performance
• Part Number: 39-34901
• Viscosity: 10W-40
• Type: Mineral engine oil
• Anti-Wear System: 2X Zinc (elevated ZDDP)
• Volume: 1 US quart (946mL)
• Designed For: Race engines, hot rods, high-performance street builds

Applications:

• Race engines — circle track, drag racing, road racing, and rally applications requiring elevated ZDDP protection and fuel dilution resistance
• Hot rod and muscle car builds — high-displacement, high-compression engines where 10W-40 viscosity and elevated zinc are appropriate
• Flat tappet camshaft applications — 2X Zinc system provides the elevated ZDDP protection that flat tappet camshafts require and that modern low-ZDDP oils cannot deliver
• High-performance street builds — modified engines running aggressive camshafts, high compression, or forced induction where standard motor oils provide inadequate protection
• Break-in applications — mineral base and elevated ZDDP make this oil suitable for engine break-in where ring seating and valve train protection are priorities
• Verify compatibility with your specific engine’s requirements before use

What’s Included:

• Maxima Performance 10W-40 mineral engine oil – 1 quart (39-34901)

Why 2X Zinc Matters for Race and Hot Rod Engines:

Zinc dialkyldithiophosphate (ZDDP) is a sacrificial anti-wear additive that forms a protective chemical film on metal surfaces under high contact pressure — particularly on camshaft lobes and lifter faces in flat tappet valvetrain applications. Modern passenger car motor oils have progressively reduced ZDDP concentrations to protect catalytic converters and meet current API certification standards. While adequate for stock engines under normal driving conditions, these reduced ZDDP levels are dangerously inadequate for race engines, hot rods, and performance builds with flat tappet camshafts, high-lift profiles, or aggressive spring pressures. Maxima’s 2X Zinc system provides double the zinc concentration of standard oils — delivering the anti-wear protection that high-performance engines demand, particularly during the critical high-load conditions of race and performance driving.

Mineral vs. Synthetic for Race Applications:

While full synthetic oils offer advantages for street and endurance applications, mineral oils have specific characteristics that make them preferred in certain race and hot rod contexts. Mineral oil’s natural friction characteristics are better suited for ring seating in freshly built engines, and mineral base stocks are more compatible with the high ZDDP concentrations required for flat tappet camshaft protection. Maxima’s race-focused mineral formulation combines the benefits of a high-quality mineral base with an advanced additive system — delivering the protection race engines need in a formulation optimized for their specific operating conditions.

Why Maxima Performance?

Maxima Racing Oils has been producing high-performance lubricants for motorsport applications since 1979, with a product lineup trusted by professional racing teams across motorcycle, automotive, and powersport disciplines. Their automotive engine oil lineup is developed with the same motorsport engineering philosophy as their racing lubricants — purpose-formulated for specific applications rather than adapted from general-purpose products.

Perfect For:

• Race engines requiring elevated ZDDP protection and fuel dilution resistance
• Hot rod and muscle car builds with flat tappet camshafts where 2X Zinc protection is critical
• High-compression and forced induction performance builds where standard motor oils provide inadequate protection
• Engine break-in applications where mineral base and elevated ZDDP are preferred for ring seating and valve train protection
• Anyone building or running a high-performance engine who wants Maxima’s race-proven 2X Zinc mineral formulation

Pro Tip: Change oil frequently in race applications — race engines subject oil to extreme heat, fuel dilution, and mechanical stress that accelerates degradation far faster than street driving. Even the best race oil should be changed after every event or at short mileage intervals to maintain maximum protection.

Note: Verify your engine’s oil viscosity requirements and compatibility with mineral-based oils before use. Not recommended for catalytic converter-equipped vehicles used beyond break-in due to elevated ZDDP content.
