First oil change on my newly acquired (Nov. 19) 2011 Aveo should be done on C.N.Y. for good luck and long and happy ownership, we hope!! The specs call for 4.75 qt, 4qt, 24 oz. No problem to measure the MOBIL ONE 5-20, but would another 8 oz to make an even 5qts cause problems associated with foaming? Thanks for any replies.
