Laura writes: I just bought a new Chevy Trailblazer with a V6. When I asked my salesman about warming up the engine, he said that it is not recommended anymore, and to just drive away. Years ago, My Dad taught me to warm up my car for at least 2 minutes every morning so the oil is warmed up. I have a dinner bet with my Husband riding on your answer. Who is right?
Laura: In today’s world, he is- let me explain: Years ago, Dad was right, a short warm up helped engines last longer. However, newer engines are designed to use better protecting 0W-20 or 5W-20 oil. These oils protect from the get go and at the same time save fuel. These advances in engine design and lubricants have changed old habits for the better. Even knowing all of this, I’d be really easy on the vehicle for the first mile or two. So, where are you taking him for dinner?
