Usually have the dealer do my oil changes but i was busy and had jiffy lube do my oil change after the first time I didn't notice it was leaking till i went from AZ to ID, got underneath and they didn't change the plug to a new one, so I took it back and they put a new one in, over the weekend but on my way back from work, smelled oil and looked at it again to sew that even with the new plug it is still leaking... causes and fixes? Plastic is warped, and gasket isn't sitting right? Now pushing 92k on it
