check your oil level as well and see where it's at.
overfilling causes premature failure of AOS which can cause a lot of oil ending up in the intake and in a cylinder finishing in hydro lock and then you need a new engine. 
whenever i have to leave my car with someone, no matter who they are i dont trust and always check all levels again. 
TRUST NO ONE!!! 
ok maybe i watched X Files too much (the old series)
