smell of something burning?

[joshx9]

first let me preface this by saying my friend changed the oil and filter to my car two weeks ago.

i started noticing the smell of oil burning a week ago, but there is no leaking to be seen on my parking spot. i can smell it when im driving with the windows down and when i put the a/c on.

i can smell it most when im down and up against my front drivers side tires, but when i pop the hood and put my face towards the engine the smell is not there.

anyone have a clue what this might be? im going to check oil levels when i get home.

thank you all in advance.
