I drive an 08 TLS. So I've noticed engine oil all over the passenger tired after coming from work. I'm not sure where it's coming from, maybe the engine gasket or the oil pan. Haven't quite look deeper yet but just wondering where it could actually be leaking from?

 

From what I can see from here it looks like its coming from the passenger side. Could be the oil pan, could be the common oil pump leak. If you post photos of the leak I bet you will get help on how to fix it.

 

Engine oil? Oil filter, gasket or filter ruptured?
Grease, CV joint?

 

If it isn't engine oil, it might be power steering fluid from the reservoir or a bad hose.
You'd get some whine on turning the wheels if it's leaking power steering fluid, though.
