Nature’s Choice® CK‐4 Motor Oils are licensed by the API as CK‐4 motor oils. This formal approval demonstrates the commitment of Nature’s Choice® to produce quality products on the leading edge of lubrication technology.
The Nature’s Choice® product line was developed in response to President Clinton’s Executive Order 13101 which mandated the use of motor oils with re‐refined content for government use. Since that time, the Nature’s Choice® product line has grown from motor oils to include many other types of lubrication. Blending virgin and re‐refined base stocks with quality additive chemistry, Nature’s Choice® brand products are able to meet the top performance grades required for today’s lubrication requirements, while being more environmentally friendly. This oil should not be used in Caterpillar TO‐4 applications, two‐cycle gasoline engines, aircraft engines, or EMD Diesel engines.
