FAQ

Is oil pressure light on while driving dangerous?

Stop driving if power is cut, brakes feel unsafe, or fluids are dumping. Tow beats a cooked engine.

How much does a typical fix cost?

DIY parts often land around $40-$400. Shop diagnosis plus repair commonly runs $200-$2200.

Should I clear the light and keep driving?

Clearing without fixing just deletes evidence. Save freeze-frame data first, then repair the cause.
