API-Licensed Heavy Duty High Performance Synthetic Motor Oil - 1 Quart, Case of 6

Royal Purple API-Licensed Heavy Duty SAE 10W-30 High Performance SN Synthetic Motor Oil is a fully synthetic oil that does not rely on crude oil, unlike traditional motor oils. It is designed to efficiently lubricate, clean, and cool engines. Motor oil comes in different weights and viscosities, with various additives added during the refining process by manufacturers. The Society of Automotive Engineers (SAE) has created a numerical code system to grade motor oils based on viscosity, with higher numbers indicating thicker oil. This oil has a weight of SAE 10W-30, which means it has an SAE viscosity rating of 10 in cold temperatures and a rating of 30 at normal operating temperature. It is important to check your vehicle's owner's manual to ensure that this is the correct weight of motor oil for your vehicle.

This is a fully synthetic oil, meaning it does not contain crude oil. Synthetic oil can be used in vehicle engines instead of motor oils refined from crude oil and often offers superior mechanical performance over traditional motor oil, including increased gas mileage and reduced engine wear at extreme temperatures. Royal Purple Motor Oil combines premium base oils with proprietary additive technologies to create high-performance motor oils that optimize engine performance and provide superior protection. No special procedures are needed when upgrading to Royal Purple, as it is fully compatible with mineral or other synthetic oils.

Royal Purple recommends waiting until the manufacturer's first scheduled oil change in new gasoline engines before upgrading to their oil. The API licensed motor oil meets ILSAC GF-5 and Dexos1 1 performance requirements, delivering superior protection while improving performance in gasoline and diesel engines.

For the best performance, it is important to follow the manufacturer's recommendations in your vehicle owner’s manual. Royal Purple motor oil offers increased fuel efficiency, improved compatibility with fuels containing ethanol, and better protection of the expensive catalytic emission system.
