Winter Oil is a No-No for your Gas Mileage

If you received an oil change in the winter, the odds are you most likely will not need to change it again until the spring, if you choose not to change it in the spring this could have negative effects on your engine as a whole.
Not only will your gas mileage decrease but you may start to see your car having problems staying functional and running properly. This is most likely caused by the moisture built up in your vehicle during the winter season as it will meld into your car and make things run a lot less smoothly.
