knocking sound after an oil change.... i would say a spun bearing maybe? did they change the oil filter? what kind of oil? blablablah

 

i got an oil change switched to synthetic, mobil 1 5w30 and yes they did change the filter

 

and how would i check if i spun a bearing

 

you can drain the oil and check for pieces of metal, you probably don't want to do that since it just got changed. It might not be a spun bearing but thats what comes to my mind when I hear a "knocking" sound. was the knocking almost like a banging sound?

 

ya it started as a knock then was a bang
