Oil Grade

[Joe T]

I have noticed a couple of times a noise from the engine almost a rod knock sound. It is intermittent doesn’t happen all the time . It happens after I run the car kind of hard and shut it off then get back in it about 15 minuets later then I will drive the car for a bit and the noise is gone. I can only hear it from outside the car and it goes away above Idle. Its time for its oil change I have been running 0W40 can I run 5W40 see if that helps I live in SO Cal so it really never gets that cold.car only has 33,000 miles also does mobile one make a 5w40 or do you have any other suggestions

There is a Porsche approved Mobil1 5W 40, but I don't know if this is it.
