Synthetic Formula

Mobil 1 FS 0W-40 is a fully synthetic engine oil, meaning it is made entirely from synthetic base oils rather than mineral oils like conventional engine oils. The synthetic base oils allow Mobil 1 FS 0W-40 to meet the latest industry and manufacturer specifications.

The key benefits of the synthetic formula include:

• Excellent low temperature fluidity. The synthetic base oils flow freely even in extreme cold, allowing for fast lubrication at startup to protect critical engine parts.

• Outstanding high temperature stability. Synthetic oils are highly resistant to oxidation and thermal breakdown, enabling extended oil change intervals without forming sludge or deposits.

• Lower volatility compared to mineral oils. The synthetic base oils evaporate much slower, reducing oil consumption.

• Improved fuel economy. The free-flowing synthetic formula provides up to 2% improved fuel economy over conventional oils.

• Advanced additive chemistry. The synthetic base oils allow for advanced additive packages to be engineered into the oil for maximum engine protection.

Overall, the 100% synthetic formula of Mobil 1 FS 0W-40 delivers exceptional all-round lubrication and protection beyond conventional engine oils. Drivers can feel confident knowing their engine is well protected with this advanced full synthetic formulation.

Another excellent option is Mobil Super 3000 X1 5W-40 - 1L, which is a versatile synthetic oil designed to provide enhanced engine performance and protection. This oil offers superior resistance to thermal breakdown and reduced wear, making it ideal for both petrol and diesel engines. Its formulation contributes to improved engine cleanliness and efficiency, ensuring your vehicle runs smoothly under various driving conditions.

Viscosity

Mobil 1 FS 0W-40 has an advanced synthetic formula that provides excellent viscosity and protection across a wide temperature range. The 0W refers to the viscosity grade when cold, with the 0W allowing for easier flow at low temperatures below -30°C. This allows for fast lubrication at startup to protect critical engine parts. The 40 refers to the viscosity grade when hot, at 100°C, where the oil maintains a thicker viscosity of 12.5 cSt to protect against wear.

This low viscosity when cold along with high viscosity when hot gives the oil exceptional thermal properties. Mobil 1 FS 0W-40 flows easily when you start your engine in frigid temperatures, circulating rapidly to critical components. But it still maintains the thicker protective film for outstanding wear prevention when the engine gets hot. The advanced formula resists viscosity breakdown and provides exceptional protection across all driving conditions, from winter cold to extreme summer heat.

Oxidation Stability

Mobil 1 FS 0W-40 is formulated with fully synthetic base oils that feature exceptional oxidation resistance. This allows the oil to effectively resist thermal breakdown even after prolonged use, keeping your engine protected over extended drain intervals.

The advanced full synthetic formula undergoes testing to demonstrate its capability to withstand oxidation for long periods under stressful conditions beyond normal driving. By resisting oxidation and thermal breakdown over time and high temperatures, Mobil 1 FS 0W-40 maintains its viscosity, keeps engine sludge and deposits minimized, and continues protecting your engine even after thousands of miles of driving.

The oil's inherent stability means you don't have to change it as frequently as you would with conventional motor oils. This saves you time and money while still ensuring your engine gets the high level of protection it needs for the long haul. Mobil 1 FS 0W-40 keeps your engine clean and running smoothly mile after mile.

Detergent System

Mobil 1 FS 0W-40 features an advanced detergent system that helps keep engines clean. The detergent additives suspend oil sludge and deposits so they can be filtered out, preventing them from clogging oil passages or sticking to engine components.

This is critical for maintaining proper oil flow and pressure, while also allowing moving parts to operate smoothly. Over time, build up of deposits can reduce engine performance and efficiency. Mobil 1's detergents help prevent this.

The detergent technology is designed to combat common issues like piston ring sticking, valve train wear, and degradation of oil. It works to continuously clean away performance-robbing deposits even under extreme driving conditions.

Tests show Mobil 1 FS 0W-40 keeps pistons up to 10% cleaner than industry standards. This allows the engine to maintain near factory-clean levels for extended drain intervals. Overall, the detergent system delivers exceptional long-term engine cleanliness.

Fuel Economy

Mobil 1 FS 0W-40 is formulated to provide enhanced fuel economy benefits while protecting your engine. The advanced full synthetic formula with friction reducing additives allows the engine to operate more efficiently.

Tests have shown that Mobil 1 FS 0W-40 can provide up to 2% fuel economy improvement compared to lower quality oils. This can translate into significant savings at the gas pump over time, especially for drivers who accumulate high mileage.

The low viscosity synthetic oil flows quickly at low temperatures while maintaining viscosity at high temperatures. This reduces pumping losses and internal friction for improved fuel efficiency. The oil readily flows into critical areas of the engine at startup while providing robust protection when the engine is hot.

Independent testing confirms that Mobil 1 FS 0W-40 meets or exceeds the requirements for fuel efficient oils identified by leading industry and car manufacturer associations. So you can be confident that by using Mobil 1 FS 0W-40 you'll be getting advanced fuel economy performance.

Switching to Mobil 1 FS 0W-40 is an easy way to take advantage of opportunities to improve fuel efficiency without sacrificing engine protection or durability.

Oil Change Intervals

One of the biggest benefits of Mobil 1's 0W-40 oil is that it allows you to go significantly longer between oil changes compared to conventional oils. The advanced full synthetic formula is designed to hold up for extended drain intervals of up to 15,000 miles or 1 year, whichever comes first when used in gasoline engines. This resistance to thermal breakdown allows the oil to retain its viscosity and lubricating properties for longer periods of time before requiring a change. For those looking to reduce maintenance costs and downtime spent on frequent oil changes, the ability to extend drain intervals is a major plus. Mobil 1 states their 0W-40 oil meets or exceeds the most demanding standards of leading industry and car manufacturers for outstanding engine protection, so users can feel confident going the distance between oil changes without worrying about premature wear to critical engine components. Just be sure to follow the manufacturer's recommendations for oil change intervals to get the most value from Mobil 1's extended performance.

Ease of Use

Mobil 1 0W-40 motor oil is known for being very easy to pour and handle compared to other synthetic oils. The viscosity allows it to flow smoothly right out of the bottle without being overly thick or sticky. This makes adding oil or topping it off a breeze.

The fluidity also contributes to no-fuss operation in cold weather. Even in freezing temperatures, Mobil 1 0W-40 pours with ease due to advanced additives that maintain excellent flow characteristics. You won't have to fight with or wait for the oil, even on the coldest days.

Overall, Mobil 1 0W-40 offers exceptional ease of use that drivers appreciate. No struggling to get the oil into your engine. Just smooth, fast pouring every time. This user-friendly experience makes oil changes and top-offs hassle-free.

Price

Mobil 1 FS 0W-40 is competitively priced for a premium synthetic motor oil. While not the cheapest option on the market, it provides excellent value given the advanced technology and proven performance.
