In hot weather, the oil needs to maintain its thickness to prevent metal contact, which is where the second number in the rating, such as the "20" in 5W-20, comes into play. These chemical compounds are responsible for tackling the byproducts of combustion and engine stress.
Understanding Engine Engine Oil Viscosity for Optimal Performance
ACEA A3/B4 European standard for high-performance and fuel-efficient engines. Dispersants: Keep contaminants suspended in the oil so they can be trapped by the filter.
Decoding the Specifications Gone are the days of simply grabbing the cheapest oil on the shelf. Conventional oil is refined from crude oil and contains a mixture of hydrocarbons, impurities, and varying molecular sizes.
Understanding Engine Oil Viscosity Ratings for Optimal Performance
Additives: The Unsung Heroes While the base oil provides the fundamental lubrication, the additive package is what defines the performance and longevity of the fluid. In cold weather, oil needs to flow easily to protect the engine on startup, which is why we use lower viscosity ratings like 5W-20 or 0W-20.
