What is the primary service offered by Jiffy Lube?

The primary service offered by Jiffy Lube is oil changes and preventive maintenance services. This focus is essential because regular oil changes help maintain the engine's health and efficiency, preventing potential issues that could arise from insufficient lubrication. In addition to oil changes, Jiffy Lube emphasizes preventive maintenance, which includes services like fluid checks, filter replacements, and multi-point inspections, all aimed at ensuring that vehicles run smoothly and safely.

The choice reflects Jiffy Lube's reputation and service model, as the company was originally established primarily to provide quick and convenient oil changes. While the other options listed represent valuable automotive services, they are not the core offering of Jiffy Lube, which has built its brand around oil changes and general preventive maintenance to cater to a wide array of customer needs.
