Making sure you keep up with regular oil changes is one of the most important things you can do to keep your car or truck running problem free for miles to come. And an oil change is certainly one of the steps you need to take when readying your car for winter. But unless you’re absolutely diligent about changing your oil, you probably should NOT change to a lighter weight winter oil. While that might help during the winter, if you don’t change back during the summer, you could do major damage to your engine.
The best thing to do is talk with your auto mechanic about your driving and car-care habits. And be honest. The two of you together can decide what is best for your car or truck. – Will C. Sparks
