I am a trying to learn to do a few basic things myself so tried to top off my oil, which seemed a bit low. I accidentally used the oil for my old car (Ace All Seasons formulation SAE 10w30) and added enough that the oil now reads 1/4" above the high mark on my dipstick...another problem. Totally forgot that I even had the other oil and picked it up thinking that it was the new oil that I recently purchased. Have not driven it yet and don't know what to do. I added about .500 ml. Any advice appreciated.
