If you notice oil leaking on the passenger side of your Nissan Altima, it may be due to various reasons. It could be caused by engine oil seepage resulting from worn-out gaskets. Alternatively, the issue might stem from an improperly sealed oil cooler leaking oil. Sometimes, replacing the oil filter during an oil change can impact the oil cooler, weakening its seals and leading to leaks. Typically, the engine gasket is the primary suspect in such leaks, so begin your troubleshooting by examining it before looking at other components. It's advisable not to drive your car with a significant oil leak, so it's best to address the problem promptly.

    This morning, as I shifted my car, I saw a pool of oil on the concrete by the passenger side. I inspected the oil level, which was not low and not red. It was mentioned that I might have a transmission leak when I recently had an oil change. I'm unsure how to check this on my 2011 Nissan Altima 2.5s.
