I have a family member who doesn’t know anything about cars. I mean that quite literally, so the fact that she routinely sits behind the wheel of one is more than a little frightening.
Allow me to correct myself: This is a person who knows one thing about cars. She knows that they go. She knows how to make them go, how to make them “not go” (her words for stop) and how to get them to go in the general direction of her choosing.
So when this family member asked why her Toyota RAV4 was taking more gas than usual, I didn’t know exactly how to answer or what questions to ask. So I took it step by step.
