SAE 70 Synthetic Blend 12 x 1 Quart

The SAE 70 Synthetic Blend 12 x 1 Quart from EXTREME RACING OIL is engineered for serious automotive enthusiasts and mechanics who demand high-performance lubrication in modified and race-oriented vehicles. This mono-grade synthetic blend oil is purpose-built for engine applications where sustained high RPM operation, elevated temperatures, and aggressive driving conditions are the norm. Whether you're running a street-legal track weapon, a weekend drag racer, or a heavily modified naturally aspirated engine, SAE 70 oil delivers the film strength and thermal stability required when standard multi-grade oils fall short.

SAE 70 is a straight-grade oil characterized by its higher viscosity index, which means it maintains robust protection across a wide operating temperature window without the shear thinning that compromises film strength in conventional blends. The synthetic component reduces oxidation and deposit formation—critical when combustion temperatures spike during high-boost or naturally aspirated high-RPM running—while the blend retains the cost-effectiveness of petroleum basestock. At operating temperature, this viscosity ensures adequate hydraulic pressure for valve train components, cam followers, and bearing surfaces while resisting breakdown under the extreme shear forces present in precision-tolerance modified engines and solid roller cam applications.

This 12-quart case format is ideal for race shops, serious DIY builders, and fleet maintenance of track vehicles, eliminating repeat ordering and ensuring consistent fill-ups between events. SAE 70 mono-grade oils are typically selected for engines with tight bearing clearances, high-flow oil system designs, or applications where extreme summer ambient temperatures are routine; they are not recommended for cold-climate daily driving or engines requiring winter pumpability. Confirm compatibility with your engine's original equipment specifications and consult your tuner or engine builder before switching to mono-grade—some modern engines with hydraulic valve adjusters or electronically controlled variable valve timing may require multi-grade oils to function correctly.
