The pinnacle of the market consists of Group IV synthetics, such as polyalphaolefins (PAO), which offer exceptional performance in extreme temperatures and longevity. Finally, the exhaust stroke exposes the oil to high thermal loads, necessitating advanced thermal stability to prevent breakdown.

Viscosity Grades and Cold Weather Performance Viscosity is the most recognizable characteristic of any motor oil, dictating how easily the fluid flows at different temperatures. Conversely, multi-grade oils dominate the modern market due to their year-round versatility.
Multi-Grade Lubricants Single-grade oils, such as SAE 30 or SAE 40, were once the standard, offering consistent viscosity across a narrow temperature range. Dispersants work to suspend microscopic contaminants, holding them in suspension until they can be filtered out by the oil filter.
