I changed my oil yesterday and I put in 4 quarts of 10w30, then someone said it looked low and I put in another 1/2 quart of 5w30 is this okay and is 4 1/2 quarts too much?
It depends on how long you let it drain, did you change oil filter, is the engine hot..etc. Don't get hung up on how much you put (within reason of course).
