Matching Oil to Your Engine Choosing the correct oil weight is not a matter of personal preference alone; it is a decision dictated by engineering specifications. Conventional Weights Choosing the correct oil weight is not a matter of personal preference alone; it is a decision dictated by engineering specifications.
Understanding Viscosity: How Oil Weights Impact Engine Performance
Selecting the correct weight is critical for fuel efficiency, engine protection, and long-term durability, making it one of the most important decisions in vehicle maintenance. The second number in the sequence—such as the "30" or "40" in common grades—defines the oil’s resistance to thinning at high temperatures.
Older engines with looser tolerances may benefit from a slightly higher viscosity to prevent oil burning and leaks. Older engines with looser tolerances may benefit from a slightly higher viscosity to prevent oil burning and leaks.
Understanding Viscosity Numbers and What They Mean
The Meaning Behind the Numbers The seemingly cryptic code on an oil container is actually a standardized rating that describes two distinct performance characteristics. Conversely, a higher number like 15W or 20W will gel more in the cold, which can delay lubrication and cause increased stress on the engine in winter climates.
