Valvoline All Climate 10W-40 is a high-quality engine oil formulated using advanced synthetic technology to provide reliable year-round performance in passenger cars, commercial vehicles, and 4WD applications. This versatile oil delivers proven and dependable lubrication for a wide range of diesel, gasoline, and LPG engines operating under varied driving conditions.

The semi-synthetic formulation combines the performance benefits of synthetic base oils with high-quality mineral oils, resulting in an oil that offers excellent value while delivering strong protection. The 10W-40 viscosity grade provides good cold-start flow properties for effective engine protection during startup, along with a robust oil film at operating temperature that shields bearings, pistons, and valve train components from wear.

All Climate 10W-40 features an advanced additive package that delivers comprehensive engine protection including effective deposit control that prevents sludge and varnish buildup, reliable oxidation resistance that preserves oil quality throughout the drain interval, and strong corrosion inhibition for all internal metal surfaces. In diesel engines, the oil provides effective soot dispersancy to prevent abrasive wear and oil thickening.

This engine oil is recommended for passenger cars, delivery vehicles, light commercial vehicles, and 4WD vehicles running on diesel, gasoline, or LPG fuel. It is an excellent choice for vehicles with moderate mileage that do not require a full-synthetic or low-SAPS oil, offering a cost-effective balance of performance and protection. All Climate 10W-40 is suitable for both naturally aspirated and turbocharged engines, making it a practical and reliable option for everyday driving, highway commuting, and light towing applications.
