Hi R R, I'm glad to assist you. Yes. It is pre-filled with oil. But manufacturers recommend that you drain the "shipping oil" and refill with "proper PAG oil" (amount) upon installation. The other purpose of the added oil is to protect the compressor during its stay on the dealer's shelves, retailers' stores, and during transport. Once installed on your vehicle, that is when you will start to begin the a/c charging process. Get it done by a certified mechanic or your local auto repair shop. If your car appears in the vehicle fitment information below (after selecting the year, make, model, submodel, and engine size), it is a guaranteed fit part.
