Then you trust the computer and it's prompts that oil is low or it's time to change it. That's what I do with newer vehicles. 100's of thousands of miles and no problems. Now that said, ours do have dip sticks and I do keep a eye on levels. Fact is I can't remember the last time I had to add oil (on a newer vehicle) and the change prompt usually happens from the 7 to 8k mark.
