Mobil 1 0W-20 and 0W-30 Advanced Fuel Economy synthetic motor oils deliver up to 2 percent fuel economy improvement* and can save drivers more than $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 nine more miles on a tank of gas when using Mobil 1 Advanced Fuel Economy
in either 0W-20 or 0W-30. 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 miles per gallon, annual mileage of 12,500 and lifetime mileage of 150,000.
