Changing your oil regularly is one of the most important things you can do to keep your vehicle running well. And knowing the right type of oil to use is also very important.
Engine oil is classified by weight, but it doesn't refer to how much the oil would weigh if you put it on a scale. It refers to viscosity, or how easily the oil flows through the engine. Most engines operate normally at around 210°F/99°C. The viscosity, or weight, is assigned a number by how well it flows at that temperature. The lower the number, the more freely it flows.
Most vehicle engines use what's called a multigrade oil which behaves differently in different temperatures. Multigrade oils have a "W" in their viscosity number that you may have seen on a bottle of oil, something like 5W30. The W stands for winter and shows how freely it flows in colder temperatures.
That means a 5W30 oil will behave like a 5 weight oil in lower temperatures (less viscous or thinner) and a 30 weight oil in warmer temperatures (more viscous or thicker). That's important on a cold day because the oil needs to behave like a thinner oil when you start your engine since it need to lubricate engine components immediately to protect the metal components. Then as the engine warms up, it behaves like a thicker oil to prevent friction among those parts. Pretty neat trick, right?
The type of oil you use can differ depending on what type of climate you operate your vehicle in and how your vehicle is used (carrying big loads, towing, etc.). Your owner's manual contains several different recommendations based on these factors. Your service advisor can recommend the right oil for your needs. Like Shakespeare said, "Oil's well that ends well."

You know that sinking feeling when you realize one of your tires has a problem. It may be making an odd noise or behaving oddly when you're driving. You may hit a pothole or curb and one suddenly goes flat. Or you may head back to your vehicle and discover it has one tire deflated without a cl... More

There are some dashboard lights you should pay more attention to than others. One is the air bag light. If it's on and your vehicle is in an accident, your air bags probably won't do their job. Automakers began installing air bags in the late 1990's since they were mandatory in the United State... More

It's easy to get letters like PVC and PCV mixed up. PVC is a plastic that's used in a lot of things, especially plumbing pipes. And PCV is a valve that helps your engine burn off excess fumes rather than having them pollute our atmosphere. PCV stands for positive crankcase ventilation. When y... More
