I don't know what Mobil 1 3309 is. My advice to you is to find something that says power steering fluid. Here at our store, we use a Napa brand power steering fluid. Power steering is not as critical as the engine or trans on the correct fluid. So, if the Mobil 1 3309 says that it is a power steering fluid, can't see why it wouldn't hurt.
05 camry ps fluid cap mention Dex II or III, can I use Mobil 1 3309?
