The Molecular Breakdown of Conventional Oil Conventional motor oil is refined from crude oil, a complex mixture of hydrocarbons that contain varying chain lengths and impurities. It maintains its viscosity index and ability to separate metal surfaces for a much longer duration.
How Driving Habits Determine If Synthetic Oil Truly Lasts Longer
However, the superior resistance of synthetic oil to oxidation and viscosity breakdown means it copes with these harsh conditions better. Defining "Longevity" in Engine Lubricants To determine if synthetic oil lasts longer, one must first define what "lasting longer" actually means in this context.
While driving habits and climate will shorten the life of both oil types, synthetics consistently demonstrate a greater tolerance for abuse. This process, known as thermal breakdown, leads to a thinning of the oil film and the formation of sludge.
How Driving Habits Impact Synthetic Oil Longevity
Synthetic oil, however, is designed for gradual performance degradation. Extreme heat, frequent short-trip driving, and dusty conditions can accelerate the degradation of any lubricant.
