How much can I save with Mobil 1 Advanced Fuel Economy?
Mobil 1 Advanced Fuel Economy oils deliver up to 2 percent fuel economy improvement and can save drivers over $400 on gasoline over the life of their vehicles. That’s a savings of about six cents per gallon of fuel. A typical passenger car with a 20-gallon gas tank can go up to 9 more miles on a tank of gas when using Mobil 1 Advanced Fuel Economy. That equates to up to 250 more miles per year under typical conditions.  Fuel economy improvement is based on a comparison versus those viscosity grades most commonly used and a potential 2 percent fuel economy improvement.  Actual savings are dependent upon vehicle/engine type, outside temperature, driving conditions and your current engine oil viscosity.  Savings estimates are based on a gasoline cost of $3 per gallon, average fuel economy of 22.5 mpg, annual mileage of 12,500 and lifetime mileage of 150,000.

How can I determine the fuel savings that I might experience with my vehicle?
We offer an online fuel savings calculator. All you need to do is plug in the current cost of fuel, your gas tank size, the average miles per gallon you experience with your vehicle and the number of miles you drive per year.  It’s that simple. Many drivers can experience savings on gasoline purchases over the life of their vehicles.

When you say that I can experience up to 2 percent fuel economy improvement, is that compared to other synthetic motor oils, or conventional motor oils?
Fuel economy improvement is based on a comparison versus those engine oil viscosity grades, conventional or synthetic, most commonly used. Actual savings are dependent upon vehicle/engine type, outside temperature, driving conditions and your current engine oil viscosity. The higher your current viscosity equates to a greater potential for savings.

What if I don't notice improved fuel economy after switching to Mobil 1 0W-20 Advanced Fuel Economy or Mobil 1 0W-30 Advanced Fuel Economy?
Industry data confirms that lower viscosity engine oils, like the 0W-20 and 0W-30 viscosity grades offered as part of the Mobil 1 Advanced Fuel Economy line, contribute to improved fuel economy.  However, fuel economy improvement can be influenced by many factors including:  your vehicle/engine type, outside temperature, driving conditions, adjusting tire pressure and your current engine oil viscosity.

I thought Mobil 1 as a full synthetic already provided the protection my high-mileage car needs. Do I really need to switch off Mobil 1 to your High Mileage product for my high-mileage car?
Mobil 1 High Mileage is designed for high mileage vehicles that have been using conventional oils. It's true that most Mobil 1 vehicles with 75,000+ miles should be in excellent condition and would not require some of the Mobil 1 High Mileage benefits. However, most cars on the road today do not use synthetic oils, so we developed this oil specifically for these cars that would benefit from switching off conventional oil.

I'm currently using Mobil Clean High Mileage with good results. Why should I change to Mobil 1 High Mileage 10W-30, which costs more?
If your vehicle has been maintained well, Mobil Clean High Mileage represents an excellent choice. However, if you believe your engine may have sludge through less-than-adequate maintenance practices, Mobil 1 High Mileage may be the more suitable selection. Mobil 1 High Mileage helps reduce the sludge that other oils can leave behind which can result in extended engine life.  For severe cases where sludge and other heavy deposits are present, shorter oil change intervals of 3,000 miles are recommended as clean-up proceeds.

Is Mobil 1 with SuperSyn Technology a fully synthetic motor oil?
Yes, it is. To meet the demanding requirements of today's specifications (and our customers' expectations), Mobil 1 with SuperSyn uses high-performance fluids, including polyalphaolefins (PAOs), along with a proprietary system of additives. Each Mobil 1 with SuperSyn viscosity grade uses a unique combination of synthetic fluids and selected additives in order to tailor the viscosity grade to its specific application.
Back to top
What's the difference between a fully synthetic and a synthetic blend motor oil?
All motor oils are made up of base oils and additives. In general, fully synthetic motor oils contain non-conventional, high-performance fluids. Semi-synthetic oils (also called "blends") usually use a small percentage of non-conventional, high-performance fluids in combination with conventional base oil.
Back to top
What's the overall benefit of Mobil 1 with SuperSyn Technology?
Mobil 1 with SuperSyn Technology exceeds the latest industry and OEM requirements. It is designed for vehicles under warranty and will provide protection for the maximum oil change interval recommended in your owner's manual or by your oil life sensor.
 
The overall goal for Mobil 1 has always been to protect your engine, even under the most severe conditions, such as cold starting temperatures, extreme high-temperature operations and high-load conditions. Mobil 1 has been formulated with a performance reserve to provide you the peace of mind that your engine is protected during these severe conditions. But Mobil 1 with SuperSyn is not just for extreme service. You can also realize Mobil 1's benefits of improved engine cleanliness and extended engine life under "normal" service.
