Every responsible owner knows that oil represents the blood flow of any vehicle, especially older vehicles with high mileage. It needs to be said that even though most cars retain their functional principles over the years, the aging process does affect their operational parameters. For instance, older cars require a more refined type of oil, the type that’s specially formulated to maintain optimal wear protection via antioxidants and various dispersancy systems.

Having said that, we should point out that high mileage cars have fairly peculiar needs when it comes to oil and you should take the time to figure out exactly what type of oil your car requires sooner rather than later. Bear in mind that the longer you use your car, the less likely it is that your regular oil will be up for the task. To give you some insight on the matter, we put together a list of the ten best high mileage oils money can buy right now.
