I already did a search and did not find any results.

I had my oil changed today and the stupid bastards put regular 10W30 in. I've been using synthetic since my second oil change, and I know I was told you can't switch back. The car was driven out of the garage, and then right back in to get drained and synthetic oil put back in. A total of literally 10 feet. Am I being paranoid, or should I do something to prevent any damage to the engine???

 

you're fine

 

no need to worry

 

Thanks for the reassurance guys. Much appreciated.
