  • Reliable Protection for High Mileage Engines
Size: 5 Quart Style: Extended Performance High Mileage Configuration: 5W-20
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! ... show more

Both our cars are over 150k miles and they run like new, all due to this product. Keep your oil changes regularly, on time, use genuine oil filter products and you should see your car perform longer.

  • Poor packaging
Size: 5 Quart Style: Extended Performance High Mileage Configuration: 5W-20
The oil and filter was correct as ordered, but the box that the oil was shipped in was too big for the two containers. It allowed the contents to shift and bounce around. The box was partially opened, the filter was loose out of its box. I’m amazed that there were not any oil leaks.

  • Amazing oil
Size: 5 Quart Style: Extended Performance High Mileage Configuration: 5W-20
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. ... show more
