Reliable Protection for High Mileage Engines
I’ve been using Mobil 1 Extended Performance High Mileage 5W-20 for my vehicle, and I’m very satisfied with the results. It runs smoothly and feels noticeably more refined after the oil change. I appreciate that it’s designed specifically for higher mileage engines—it helps reduce engine wear and keeps things running efficiently. I’ve also noticed less engine noise and a smoother startup, especially on colder mornings. The 5-quart container is convenient and makes oil changes easy without needing multiple bottles. Overall, this is a trusted, high-quality oil that gives me confidence in my engine’s long-term health. Definitely worth it for anyone wanting reliable protection and performance!

Quality that lasts
I’ve tried a lot of different oils in my time, but I’ve always found them. This brand has been rated as one of the best out there. And it is also one of the most affordable.

Amazing oil
I have a '17 KIA with 2.0L Turbo. I switched to a major brand synthetic oil after about 10,000 miles. About 7 years later at 55,000, I started seeing oil consumption. I had been using Mobil1 0W-20 Hi-Mileage/Ext. Performance in our Honda van for years and we had zero problems with it - that engine is known to have oil fouling issues resulting in overhaul or new engine. So, I decided to use it (5W-30) in the KIA. It took two yearly changes to stop the oil use. I just checked it today, 4000 miles since the last oil change and NO OIL USAGE! I think this oil is mandatory for any vehicle over 50,000 miles - at least it is in my driveway. You might wonder how it 'cured' that engine - dissolving hard carbon is what it does. Once the piston rings are freed to expand, they seal the cylinder like they're designed to do and oil consumption stops. Engines that have broken rings or scored cylinders from the carbon build-up may not have the best results, but it sure doesn't hurt to try. You do have to give it time to work. The best thing is to start using it before the trouble starts.

Good oil, will keep buying
Haven’t had any issues with it. Doesn’t last the advertised 20k as oil will thin out before then.
