In this video, I tested and compared a bunch of popular high mileage engine oils to figure out what’s actually worth your money if your car is past that 75,000-mile mark. High mileage oil isn’t just a marketing label—these formulas are built with additive packages and seal conditioners that can help older engines stay quieter, reduce wear, and in some cases cut down on oil consumption and small leaks. I also break down what “high mileage” really means, and when it makes sense to switch versus just sticking with the manufacturer spec. I go through the main picks I’d tell my own friends to buy—covering options like Mobil 1 Extended Performance High Mileage and several Valvoline formulas (including MaxLife and Restore & Protect). The big takeaway: the “best” high mileage oil depends on what problem you’re trying to solve—longer drain intervals, general wear protection, or cleaning and protecting an older engine. If you want my overall budget and best pick, I linked it so you can grab the exact one I recommend.
