The synthetic base stock resists thermal breakdown, ensuring that the oil remains effective at forming a protective barrier between pistons and cylinders even when the engine is running at maximum temperature. The Science Behind 5W-20 Viscosity The "5W-20" designation describes the oil's viscosity, or its resistance to flow, which is critical for engine protection.
This stability is vital for maintaining engine cleanliness and longevity. Following the schedule outlined in your vehicle's manual is essential, but many drivers find that the superior resistance to oxidation allows for extended drain intervals without compromising engine protection.
