Q: Is the oil pan gasket the same thing as oil gasket

The term "oil gasket" is not helpful. It could refer to any number of gaskets in your engine. . "Oil pan gasket" however is a specific name that refers to the gasket on the oil "sump" or "pan" Gaskets are joints, they fit between two parts that are bolted together to provide a seal between them. It could be that someone was telling you that you needed an oil pan gasket, but was careless with their terminology. As for your "add oil" light, it’s possible that the shop that worked on your car didn’t refill the engine oil properly after doing the job. If you aren’t getting any other warnings, then you probably just need to add a quart of oil. If you don’t feel comfortable doing that, contact YourMechanic, they can send a technician to your home or office to check the oil level in your car and add oil for you right there on the spot.
