GM 10W40 1L Engine Oil - Purpose and Specifications

GM 10W40 1L premium engine oil (part number 93165213) delivers reliable protection for gasoline and light diesel engines, meeting ACEA A3/B4 and API SL/CF standards. Its 10W-40 viscosity flows smoothly in cold starts down to -25°C, protecting moving parts from wear right away, while staying thick enough at high temps up to 150°C for consistent lubrication during heavy loads.

This oil reduces friction, fights sludge buildup, and keeps pistons and valves clean for smoother operation and better fuel efficiency. Ideal for GM vehicles and others specifying these specs, it supports engines up to 75,000+ miles by minimizing leaks and extending life.

• Replace every: 10,000-15,000 km or 12 months for everyday use; check level monthly if your engine uses oil.
