So I changed the oil on my zl1 after it sat in the garage all winter.
Stupid me I did not run it before the oil drain.


I pre filled the oil filter and poured the new oil in.


At startup I heard a knock noise for a second or two. It freaked me out.


Cars runs fine and noise free.


I dont remember hearing this before.


Did this happen to anyone here?


Thanks in advance
