FAQ: Does Fuel Economy Oil Work Bob?

What oil is best for fuel economy?

Fuel-economy oils have become popular over the last several years, especially the 0W20 and 5W20 oils. Most of these oils will provide at least a 1- to 2-percent increase in fuel economy over using the next viscosity grade.

How does Advanced fuel economy oil work?

How does this work? During warmup, Mobil 1 Advanced Fuel Economy oil flows faster because of its lower viscosity, which can minimize metal-to-metal contact to reduce friction and wear. Actual savings are dependent upon vehicle/engine type, outside temperature, driving conditions and your current engine oil viscosity.

Does high mileage oil do anything?

It can help reduce oil consumption, smoke, and emissions from older engines. High mileage oil also works to minimize leaks and oil seepage. While you could use high mileage oil in a younger car without harming it, the issues that high mileage oil addresses usually don’t appear in vehicles with fewer than 75,000 miles.

Does thinner oil improve fuel economy?

Technically, yes, as thin oil flows through the engine with less resistance than thicker oil. Some dedicated “hypermilers” — drivers who treat getting the best possible mileage almost as a game — insist it makes a small difference, usually less than a half-mile per gallon.

Which is better 5w30 or 10w40?

The first number in the motor oil’s name describes the oil’s cold viscosity. A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

How can I improve my fuel economy?

10 Easiest Ways To Boost Your Vehicle’s Fuel Economy

  1. Drive Smoothly. Potential savings: 54 Cents Per Gallon.
  2. Slow Things Down.
  3. Keep Your Left Foot Off The Brake Pedal.
  4. Turn Off The Engine At Idle.
  5. Clean Out The Trunk.
  6. Take Time For A Tune Up.
  7. Choose The Right Motor Oil.
  8. Pay Attention To Tires.

Is 0W20 the same as 5w30?

0W-20 OIL. It readily means that the 0 oil will flow well and better at a cold temperature more than 5W-30 oils even while maintaining the same viscosity. The 0W-20 is said to be the best oil in the market because it helps to reduce environment hassle on waste oil disposal.

Is 0W-20 oil the same as 5W20?

0W-20 synthetic oil’s range is between -40°C to 20°C while a 5W20 (5W20 synthetic oil) is from -35°C to 20°C. It is better to use 0W20 oil if you live in a place with very cold temperatures, such as Alaska or Maine. You cannot use either 0W20 or 5W20 in areas where temperatures exceed 20°C/68°F like Florida.

How many miles is 0W20 good for?

Mobil 1 High Mileage 0W-20 advanced full synthetic motor oil is designed to help extend the engine life of vehicles with over 75,000 miles and protect critical engine parts for up to 10,000 miles between oil changes.

Is there really a difference between high mileage oil and regular oil?

High-mileage oils have ingredients to take care of older engines, like conditioners, seal swells, antioxidants, detergents and wear or friction additives. Typically they use a viscosity modifier that is durable and won’t lose viscosity very easily. These oils need to stay thicker longer to protect engine parts.

Should I use thicker oil in a high mileage engine?

High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.

What’s the difference between high mileage oil and synthetic?

High mileage oil is designed for vehicles with more than 75,000 miles. As a rule of thumb, most new cars require synthetic oil. Older cars generally run well with conventional oil, unless your vehicle has more than 75,000 miles on it, in which case high-mileage oil is recommended.

Why do modern engines use thinner oil?

Thinner oils are being used these days for three reasons: They save fuel in test engines, the viscosity rules have changed, and manufacturers are recommending thinner grades. The Sequence VI-B is the test used to evaluate fuel economy for the GF-3 specification.

Which oil is better 10W30 or 10W40?

Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.

Will thinner oil damage engine?

What happens when you add a thicker oil to a thinner oil (or vice versa)? Again, if you accidentally mix thicker motor oil with thinner motor oil, it will not damage your car’s engine (not for that one time you “accidentally” do it, at least).
