Why Choose CK4 Engine Oil
Engine sizes and component changes are being driven by changes in fuel economy and industry standards. Engine oil operating temperatures are frequently higher as a result. DOXA has created the 10W30 CK 4 engine oil for this reason. What’s changing? Many next-generation engines will operate at greater operating temperatures in order to achieve targets for more fuel-efficient engines and lower emissions. To do this without compromising engine protection, adjustments to engine oil composition will be necessary. Also, it will result in the creation of two categories of engine oils: CK-4 and FA-4. The engine oils you are currently using will be directly replaced with CK-4 engine oils, which will also be "backwards compatible" with all current vehicles. The new FA-4 engine oils, which are primarily for next-generation engines and are available in lower viscosity grades, are intended to increase fuel efficiency without compromising engine protection. These FA-4 oils would be...
