Heavy Duty Motor Oils
XProlube Viridis Synthetic Blend Heavy-Duty Engine Oil SAE 25W-60
XProlube Viridis SAE 25W-60 is a high-viscosity synthetic-blend heavy-duty engine oil engineered for severe-service and high-temperature operation in older or hard-working diesel, gasoline, and propane (LPG) engines — naturally aspirated, turbocharged, or supercharged — across trucking, construction, mining, and agricultural fleets. Blended from synthetic and high-quality conventional base oils with a premium additive package (detergents, dispersants, anti-wear, anti-oxidant, anti-corrosion, and anti-foam agents), the heavier 25W-60 grade maintains oil pressure and film strength under extreme loads and heat, curbs oil consumption in high-mileage engines, and resists sludge, varnish, and deposit formation to extend engine life.

Applications
- Heavy-duty diesel engines in trucks and equipment requiring API CH-4 performance level
- Pre-2007 diesel engines without diesel particulate filters (DPF) meeting API CF-4 specification
- Older diesel engines requiring API CF-2 or CF performance in marine and industrial applications
- Gasoline engines in trucks and equipment requiring API SL performance level
- Mixed fleets operating both diesel and gasoline engines where single oil specification is preferred
- High-temperature operating conditions requiring the thermal stability of SAE 25W-60 viscosity grade
- Heavy-duty applications with high oil consumption where thicker viscosity grade provides better retention
