Frequently asked questions

Is it safe to drive with a burning oil smell?

Drive cautiously and check it soon — a leak onto hot parts is a fire risk and signals oil loss that can harm the engine.

Why do I smell burning oil but see no leak?

A small leak can burn off on hot surfaces before it drips, so it smells without leaving a puddle under the car.
