Lubriguard™ Synthetic Blend SAE 15W-40 CK-4/SN Engine Oil is formulated for use in high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel engines. It is formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm. Use of this oil with greater than 15 ppm sulfur fuel may impact exhaust aftertreatment system durability and/or oil drain interval. It is especially effective at sustaining emission control system durability where particulate alters and other advanced aftertreatment systems are used. API CK-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate alter blocking, engine wear, piston deposits, degradation of low and high-temperature properties, and soot-related viscosity increase. Meets or exceed the performance criteria of API CJ-4, CI-4 PLUS, CI-4, and CH-4. Approved for use in applications calling for Ford Specification WSS-M2C171-F1.

Great price!
I love that I can order these on Amazon for less than half of what I would pay at the mechanic. They fit perfect, and they're a pretty easy install.

Easy to install and works perfectly
Great price. It does what it's supposed to do. Keeps my air flow clean. Super easy to install, I can't believe mechanics charge to do this. Once you see how easy it is, you'll save yourself that expense. The material is top-quality charcoal, so it cleans all the nasty mold particles from getting into the vehicle. There is no smell, and that is a plus.
