Both oils exhibit good high-temperature performance, but Mobil 1 High Mileage may have a slight edge due to its thicker consistency. This thicker oil is better suited to withstand extreme heat conditions, providing added protection for your engine.

Regular Mobil 1, although capable of withstanding high temperatures, mightn’t be less robust in extreme heat conditions. Also, the regular Mobil 1 formula does not contain the same seal conditioners as the High Mileage version, meaning it may be less effective in identifying and helping prevent oil leaks.

No 05: Deposits and Sludge Control

If you want to effectively control deposits and sludge in your vehicle’s engine, Mobil 1 High Mileage motor oil is the way to go. This oil contains more detergents than regular Mobil 1, making it more effective at addressing issues commonly found in older engines with looser tolerances.

Deposits and sludge can build up over time, especially in engines with higher mileage, negatively impacting engine performance and longevity. The extra detergents in Mobil 1 High Mileage help to break down and remove these deposits, keeping your engine clean and running smoothly.

Regular Mobil 1, although effective at preventing deposits, may not contain the same level of detergents needed for high mileage engines. Because regular Mobil 1 oil can’t always remove the existing deposits, switching to Mobil 1 High Mileage is a great way to ensure your engine gets the deep cleaning it needs.

No 06: Viscosity Grade Options

Both oils offer a range of viscosity grades to suit different climates and driving conditions.

However, Mobil 1 High Mileage, specifically designed for older engines, typically offers slightly thicker viscosity options than regular Mobil 1. Older engines often have looser tolerances, and a thicker oil can help compensate for any wear and tear.

Thicker viscosity grades, such as 10W-30 or 10W-40, are commonly available for Mobil 1 High Mileage. Meanwhile, regular Mobil 1 may offer a wider range, including thinner options like 0W-20 or 5W-30.

No 07: Compatibility with Catalytic Converters

For catalytic converters, using high zinc and phosphorus oils, like some high mileage oils, may raise concerns about the longevity of the converter. These oils can potentially damage the catalysts inside the converter, leading to reduced efficiency and increased emissions.

On the other hand, regular Mobil 1 motor oil meets stricter emissions standards and is generally considered more compatible with catalytic converters. It’s designed to provide optimal protection and performance while ensuring the longevity and effectiveness of the catalytic converter.

No 08: Compatibility with Older Engines

Mobil 1 High Mileage is specifically formulated to meet the unique needs of engines with higher mileage. It contains additives that help to reduce oil leaks, minimize oil consumption, and prevent engine wear.
