10 Top-Rated Oils and Additives for High-Mileage Vehicles

Cars last longer than they did just a decade ago. According to the Bureau of Transportation Statistics, in 2016 an average car lasted 11 years, up from eight years a decade prior. So, if you drive an average of 13,000 miles a year, that puts you well over six figures of mileage by the end of your car’s lifespan. Thankfully, there are a variety of products for oil and fuel to keep your engine running longer. (No matter what you use, remember to change your fluids often, keep your ride clean on the topside and the bottom, and take it easy on the hard starts, hard brakes, and violent turns.)
