Understanding Why Your Oil Light is Flickering: A Quick Guide to Diagnose Your Vehicle's Oil Issue

The oil light on your dashboard is a critical warning indicator that should never be ignored. When it begins to flicker, it generally signals a fluctuation or drop in your car’s oil pressure or levels. Common causes of a flickering oil light include low oil levels, a faulty oil pressure sensor, a failing oil pump, or even degraded oil quality. Mechanical issues such as worn engine bearings can also result in oil pressure irregularities. If you notice this warning, it’s important to address it immediately: check your oil level using the dipstick, top up if necessary, and schedule a professional inspection if the issue persists. Neglecting a flickering oil light can lead to engine damage or complete failure.

Tips 1:

As a designer, when dealing with any malfunction or warning in your living or working space, I always recommend integrating both function and form.
