As the temperatures plunge, certain types of engine oil may not flow as easily as they did when it was warmer. Makes sense, doesn't it? Just like molasses gets thicker as the temperature goes down, engine oil does the same thing. So, maybe you're wondering if you have to change your oil as the seasons change so it's just the right thickness to lubricate your engine parts. How well engine oil flows is called its viscosity. There are different types of oil—some that have just one viscosity and others called "multigrade" oils. Here's the difference. A single viscosity oil will flow better when it's hot but not as well when it's cold. A multigrade oil is engineered so that its flow properties at cold temperatures are different than they are at warm temperatures. In other words, a multigrade oil can start out in colder temperatures acting like a thinner oil and then behave like a thicker oil when it's warm. That's a pretty cool trick and it's why mu ... read more

You swap your winter boots for flip-flops in the summer. Why not change your winter engine oil for summer, hot-weather oil? While it may seem like it makes sense, there's some good news. Most drivers don't have to, and here's why. Engine oil can be made in different thicknesses. That thickness is called viscosity, how easily it flows. Now, it makes sense that the hotter it gets, oil gets a little thinner and doesn't lubricate as well. So if you used a thicker oil in the summer, it's logical that it would protect better in the hotter weather. While there was a time when oils could be only made in one viscosity, times have changed. Using an ingenious formula, oil can now be created that changes its viscosity (called "multi-viscosity") as the temperature rises and falls. It self-adjusts to match the conditions. Now that's what I call a great invention. In most temperate climates, you don't have to swap out the type of oil you use ... read more

You've heard that expression, change is good. When it comes to your vehicle's oil, change is not only good, it's vital for the health of the engine. But there's one question that puzzles many drivers: how frequently should my vehicle's oil be changed? There is not one simple answer, but here are some guidelines that will help. It used to be pretty much a rule of thumb that vehicles got their oil changed once every 3 months or 3,000 miles/5,000 kilometers. But times have changed. Oil formulations have gotten better and engine designs have made longer oil change intervals possible. Most experts advise you to read the recommendations that come from the manufacturer that designed and built your vehicle. Their designers and engineers know more about your vehicle than anyone else. They spell out their recommended oil change interval and type of oil in your owner's manual. Many automakers say you can go at least 5,000 miles/8,000 kilometers betw ... read more
