Maximize Heavy Duty Diesel Equipment Reliability and Engine Protection in Oil and Gas Operations

Oil and gas production environments demand continuous, unyielding operation from heavy equipment. Upstream drill sites and midstream operations rely on high-speed four-stroke diesel engines to power Tier 4 non-road equipment, stationary power generators, and heavy-duty transport vehicles.

In these remote, high-stress environments, lubricant failure leads directly to unscheduled downtime, elevated oil consumption, and accelerated component wear. To tackle these operational demands, Bel-Ray® Hyperion® Synthetic Blend CK-4 Engine Oil provides thermal stability, shear protection, and low-temperature fluidity while simplifying inventory across mixed fleets and is warranty compliant for all vehicles requiring a licensed API CK-4 diesel engine oil.

Engineered for Extreme Field Operations

High-load power delivery, continuous duty cycles, and severe weather rapidly accelerate oil oxidation. Bel-Ray Hyperion Synthetic Blend utilizes premium synthetic-blend base stocks and advanced additive chemistry to maintain oil integrity under severe mechanical stress. Featuring a pour point of -48°C (-54°F) and low cold-cranking viscosity, it ensures rapid fluid circulation during freezing morning startups to protect critical journals and bearings from dry-start wear.

Conversely, high flash point properties (229°C / 444°F) and exceptional thermal resistance reduce oil volatility and oil consumption during sustained high-temperature operations. Its shear-stable formula further guards against viscosity loss from mechanical stress while minimizing oil aeration to preserve film strength across valvetrains and bearings.

Emission System Protection and Soot Management

Modern diesel engines rely on sensitive aftertreatment systems, including Selective Catalytic Reduction (SCR) catalysts and Diesel Particulate Filters (DPFs). Substandard lubricants can poison catalysts or block filters, triggering engine derate conditions and costly downtime.

Bel-Ray Hyperion CK-4 15W-40 features a low-ash formulation (0.98 wt% Sulfated Ash) specifically engineered to prevent particulate filter blocking and catalyst fouling while controlling piston deposits. The advanced additive package effectively disperses soot to prevent viscosity spikes, sludge formation, and abrasive wear. Furthermore, it provides fuel flexibility for field operations utilizing diesel fuels with sulfur content up to 500 ppm.

Fleet Consolidation & Comprehensive OEM Compliance

Managing separate lubricant inventories for light-duty service trucks, legacy diesel units, and modern heavy machinery increases operational risk and carrying costs. Bel-Ray Hyperion Synthetic Blend SAE 15W-40 holds dual API CK-4 / API SN licensing. This enables fleet managers to consolidate inventory into a single oil that services modern heavy-duty diesels, older legacy engines requiring CJ-4 or CI-4 PLUS standards, and gasoline support vehicles requiring API SN performance.

The formulation maintains broad warranty compliance and meets or exceeds key manufacturer specifications, including Caterpillar ECF-3 and ECF-2, Cummins CES 20086 and CES 20081, Detroit Diesel DFS 93K222 and DFS 93K218, Ford WSS-M2C171-F1, Mack EOS-4.5, Volvo VDS-4.5, MTU Category 2, and ACEA E11-2022 standards.

Sizes & Viscosity Flexibility For Field Deployment

With typical kinematic viscosities of 110.5 cSt at 40°C and 14.8 cSt at 100°C (Viscosity Index 139), Hyperion delivers dependable film strength across full operational temperature ranges. To support varying field delivery and storage configurations—from central supply depots to mobile lube trucks—Bel-Ray supplies Hyperion CK-4 15W-40 in 1-gallon jugs, bag-in-box systems, 5-gallon pails, 55-gallon drums, 275-gallon totes, and bulk delivery. We also offer SAE 10W-30 CK-4 in drum and bulk sizes as well.

By combining superior deposit control, wear resistance, and extreme temperature performance into a single universal oil, Bel-Ray Hyperion CK-4 Engine Oil helps operators extend engine life and maximize uptime across the oil patch.
