Schaeffer's API SQ engine oils work for all gasoline engines.

Upgrade Your Engine's Protection with Schaeffer’s SQ Engine Oils

As the automotive industry continues to evolve, so too must the lubricants that power our vehicles. That's why we're excited to introduce you to the latest motor oil specification: API SQ.

Developed in response to automakers' requests for enhanced engine protection, API SQ is designed specifically for turbocharged gasoline engines. These advanced engines are susceptible to a phenomenon known as Low-Speed Pre-Ignition (LSPI), which can lead to costly engine damage if left unchecked.

Schaeffer’s SQ engine oils have been formulated to mitigate the effects of LSPI, providing your engine with the robust protection it needs to perform at its best. But the benefits don't stop there. These oils are also backward compatible with older API specifications, ensuring they'll work seamlessly in both newer and older vehicles.

By upgrading to API SQ, you'll enjoy the peace of mind that comes with knowing your engine is safeguarded against the unique challenges of today's turbocharged technology. Plus, with the added assurance of backward compatibility, you can be confident that your motor oil will continue to deliver reliable performance, no matter the age of your vehicle.

Testing shows that Schaeffer’s SQ gasoline engine oils offer: 

• 48% Lower valvetrain wear (iron ppm) vs. API and GM limits 
• 29% Better wear protection vs. API and GM wear limits 
• 37% Better protection against timing chain wear and elongation vs. API and GM limits

Don't settle for anything less than the best for your engine. Upgrade to API SQ motor oil and experience the difference in power, efficiency, and long-lasting protection. See how Schaeffer's API SQ oils can take your driving experience to new heights.
