10 Best Motor Oils 2025 in the United States

Mobil 1 Advanced Fuel Economy Full Synthetic Motor Oil 0W-20 is designed to enhance fuel efficiency with its low-viscosity formulation. Being a full synthetic oil, it offers superior protection and performance compared to conventional oils. One of its standout features is the Triple Action Formula, which ensures excellent engine performance, cleanliness, and protection, helping to extend the life of your engine by preventing the buildup of deposits and sludge. This oil meets the ILSAC GF-6 standards, providing low-speed pre-ignition and timing chain wear protection, which are critical for modern engines.

Another key advantage is the long oil change interval, allowing up to 10,000 miles between changes, which can be convenient for those who prefer less frequent maintenance. This motor oil has received high customer ratings, indicating strong user satisfaction. However, synthetic oils like this can be more expensive upfront compared to conventional oils. Additionally, while the 0W-20 viscosity is great for fuel economy and cold starts, it may not be suitable for all vehicle types, particularly older models that might require a different viscosity.

This product is highly suitable for those looking to improve fuel economy and engine protection in their cars and trucks.

Mobil 1 Advanced Full Synthetic Motor Oil 5W-20 is a high-quality option designed to offer excellent engine performance and protection. Its synthetic nature helps it perform better under extreme temperatures, maintaining good viscosity whether it is hot (up to 500 degrees F) or cold (down to -30 degrees F). This oil meets the ILSAC GF-6 standards, ensuring it offers low-speed pre-ignition (LSPI) and timing chain wear protection, which are critical for modern engines.

It also improves fuel economy and helps keep your engine clean by preventing deposits and sludge buildup. One of its standout features is its long oil change interval, allowing you to go up to 10,000 miles between changes, which can save time and money in the long run.

Despite its excellent performance and protection qualities, you may need to consider availability and potentially look for similar alternatives within the Mobil 1 range or other brands as this product has been discontinued. Its viscosity of 5W-20 makes it suitable for a broad range of vehicles, including cars and trucks. If you prioritize engine longevity and performance, and can find it in stock, this motor oil is a strong candidate.

Valvoline Full Synthetic High Mileage with MaxLife Technology 5W-20 is designed specifically for cars and trucks with over 75,000 miles, making it a great choice if you want to protect an older engine. It’s a full synthetic oil, which generally offers better performance and longer-lasting protection than conventional oils. The 5W-20 viscosity means it flows well in cold starting conditions while still protecting your engine at normal operating temperatures. This oil includes special additives called seal conditioners that help prevent and even treat leaks—something common in older engines.

It also provides 50% better wear protection than the industry standard, plus extra defense against deposits, sludge, corrosion, and rust, helping to keep the engine cleaner and running smoother over time. On the ratings front, it meets or exceeds current industry standards (ILSAC GF-6A, API SP, and others), so it’s suitable for modern engines and offers reliable protection. Made in the USA by a trusted brand with over 150 years of history, it’s widely well-reviewed by customers for performance and longevity.

The 5W-20 viscosity is best matched to vehicles that recommend this grade—using a different viscosity may not provide optimal protection. While synthetic oils often allow for longer intervals between changes, always follow your vehicle manufacturer’s recommended oil change schedule. If you drive an older vehicle looking to extend its life with high-quality protection, this Valvoline oil is a solid option that balances advanced technology with proven performance.
