Indicates degradation of the base oil and additive shearing. Base Number (TBN) Reserve alkalinity to neutralize acids.
Conventional wisdom suggests changing oil every 3,000 or 5,000 miles, but modern synthetic formulations can often last significantly longer if the contamination levels are low. By interpreting these results, a mechanic or informed owner can transition from time-based maintenance to performance-based maintenance, ensuring optimal protection and avoiding premature wear.

Why Regular Oil Analysis Matters Regular oil analysis matters because it transforms maintenance from a calendar exercise into a precise diagnostic procedure. The oil is drawn from the drain plug—after draining the bulk of the oil—to capture the debris that has accumulated at the bottom, rather than taking a clean sample from the dipstick tube.
