Origin of the 3,000-Mile Rule

The 3,000-mile oil change rule was heavily marketed by fast-lube chains since the 1970s. Promoted as a safe bet to protect your engine, this practice is also a remnant of the era dominated by conventional oils, which necessitated frequent changes to maintain engine health.

The Role of Synthetic Motor Oils

The development of synthetic motor oils has dramatically shifted the landscape. These oils offer superior wear protection, better temperature resistance, and longer-lasting performance compared to their conventional counterparts. High-quality synthetic oils, such as AMSOIL Signature Series Synthetic Motor Oil, can protect your engine for up to 25,000 miles or one year, far exceeding the old 3,000-mile rule.
