It offers superior high-temperature stability, improved cold start performance, and advanced detergency to maintain cleaner engines over longer oil change intervals. Compatible with both gasoline and diesel engines, it supports mixed fleets and protects modern and older engines by minimizing wear, deposits, and oxidation. ## Description Duragard Diamond Plate Synthetic Blend CK-4 SAE 10W-30 is an extreme performance (HTHS) high-temperature, high-shear viscosity synthetic blend oil formulated to meet the significantly improved specifications for 2017 and newer engines while being fully compatible for 2016 and prior engines that previously used API CJ-4. API CK-4 will deliver more oxidization protection for hotter, heavy-duty engines, minimizing acid formation, deposits and viscosity increase, promoting reduced wear, improved shear stability, greater oxidation stability, and foam prevention.Duragard Diamond Plate Synthetic Blend CK-4 SAE 10W-30 is specifically engineered for use in mixed fleets, gasoline and diesel. CK-4 has a select additive package for exceptional performance at high temperatures and heavy loads with improved engine protection over previous CJ-4 formulas. The advance in oil technology standards establishes an oil quality specification that helps protect today and tomorrow diesel engines.Duragard Diamond Plate Synthetic Blend CK-4 SAE 10W-30 is a direct replacement for CJ-4 using the same viscosity grades in Synthetic or Synthetic Blend oil types providing protection for all future engine designs, while improving protection of current and previous engines. CK-4 and CJ-4 can be mixed and should have no detrimental impact to engines. However, it is recommended to completely change over to CK-4 oil by using a hot drain of the CJ-4 oil to help minimize residual oil and achieve full benefits of the new oil. Fleets using CJ-4 should implement a secondary storage for CK-4 or completely empty a CJ-4 tank before filling with Duragard Diamond Plate SAE 10W-30 API CK-4 Engine oil. ## Features - Exceeds warranty requirements of engine manufacturers that require a type API CK-4/SM premium synthetic blend SAE 10W-30 motor oil. - Resists fluid breakdown better at high loads and temperatures while providing much easier starting at low temperatures. - Low ash detergency combined with super-dispersion action controls engine deposits and soot to maintain cleaner engines over extended oil change intervals. - Meets Ford’s stringent 2017 and newer WSS-M2C171-F1 specification. - Backwards compatible for all engines currently requiring CJ-4 ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Duragard Oil | | Brand | Duragard | | Is Discontinued By Manufacturer | No | | Manufacturer Part Number | DURCJ410/30P | | Viscosity | 10w30 | ## Product Details - **Viscosity:** 10w30 - **Brand:** Duragard - **Liquid Volume:** 640 Fluid Ounces - **Package Information:** Can, Pail - **Vehicle Service Type:** Truck ## Images ![Diamond Plate Synthetic Blend CK4 10w30 Engine Oil - 5 Gallon Pail - Meets Ford WSS-M2C171-F1 - Image 1](https://m.media-amazon.com/images/I/71REcoVvjKL.jpg) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/67061943-diamond-plate-synthetic-blend-ck4-10w30-engine-oil-5-gallon](https://www.desertcart.co.za/products/67061943-diamond-plate-synthetic-blend-ck4-10w30-engine-oil-5-gallon) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-24*
