While the traditional 3,000-mile rule is largely obsolete, the calendar-based schedule for synthetic blends and full synthetics requires a more nuanced approach than many drivers realize.
This superior chemistry allows the lubricant to maintain its viscosity and protective properties for an extended duration. Adjusting for Driving Conditions The environment in which you drive significantly impacts the degradation rate of your lubricant.
