Let’s start things with Viscosity:
Every engine oil is available in a variety of viscosities which makes it more suitable to be used in higher or lower temperatures.
Mobil 1 advanced fuel economy is available in 3 different viscosities, which are 0W-16, 0W-20, and 0W-30.
According to the SAE standard, this motor oil is most suitable for lower temperatures, and has low viscosities and gives you a quick cold startup.
Here, for example, the digit 0 stands for the grade at low temperature, with W indicating winters and the digits 16, 20 and 30 indicate the grade at normal temperature.
The engine oil is normally thin during start-up so that it can quickly pass through the cold engine, and once heated up, the oil becomes thicker so that it is not consumed a lot.
This motor oil meets and exceeds the API standard and the ILSAC GF-6A standard.
Mobil 1 high mileage is available in 4 different viscosities or grades, which are 5W-20, 5W-30, 10W-30, and 10W-40.
According to the SAE standard, this engine oil is suitable for both lower and normal temperatures.
The digits 5 and 10 indicate the grade at a lower temperature, with W indicating winters, and the digits 20, 30, and 40 indicate the grade at normal temperature.
The viscosity index improvers help maintain the quality and performance during extreme low or high temperatures and prevent any thermal breakdown.
This motor oil meets and exceeds the API standard and the ILSAC GF-6A standard.
Types of these oils:
Oil type tells you about the qualities of engine oil. Full synthetic engine oils provide better protection compared to other types of oils. Luckily, both Mobil 1 advanced fuel economy and high mileage are fully synthetic motor oils.
Mobil 1 advanced fuel economy is a fully synthetic motor oil which makes it the most refined form of engine oil. This type of oil is totally manufactured in the laboratory, so it has the benefits of being formulated with unique technology and additives. Moreover, this motor oil promotes maximum engine life by providing better thermal and oxidation stability.
Mobil 1 high mileage is also a fully synthetic motor oil which makes it work best under extreme temperatures. Furthermore, being a fully synthetic engine oil, it gives out high mileage and does not require to be changed too quickly. This motor oil also gives maximum engine protection and provides smooth running.
What Additives are present in them?
Motor oils are formulated with a combination of additives and advanced technology, which helps boost performance and keeps the engine safe.
Mobil 1 advanced fuel economy motor oil has a couple of additives added into it to help maintain the oil quality and perform various vital functions. The special additives are anti-wear agents, antioxidants, active cleansing detergents, and viscosity index improvers.
Mobil 1 high mileage also uses modern additives to help provide a smooth engine running. The additives added in this motor oil are active cleaning detergents, anti-wear agents, antioxidants, seal conditioners, and viscosity index improvers.
How Catalytic converter performs with them?
Engines get heated up after running for a long time which results in oil burning off into vapors and entering the car’s emission system. This can produce by-products such as phosphorous, which may be poisonous for the catalytic converter. Moreover, an engine may misfire, which leads to incomplete combustion and causes overheating, which could also indicate the presence of a fault in the catalytic converter.
Mobil 1 advanced fuel economy uses special additives such as antioxidants which help boost oxidation and thermal stability. This, in turn, helps reduce any oil molecules from evaporating into vapors and entering the car’s emission system.
Mobil 1 high mileage uses advanced additives, which help reduce the risk of having an emission system failure. Moreover, all engine parts are well lubricated and thus protected from any harmful leaks that could damage the catalytic converter.
Do they keep the engine clean?
When the engine stays heated for long intervals, oxidation takes place as oil particles break down and combine with oxygen under high temperatures. The oil particles further break down and unite with dirt to form carbon, and in the presence of gas, coolant and water, a thick sticky paste is formed known as sludge. Sludge can cause a lot of issues such as block the valves, reducing oil pressure and thus stopping the oil circulation altogether, which would lead to damage.
Mobil 1 advanced fuel economy uses additives such as detergents which help clean the engine and reduce the formation of any sludge built up. Moreover, the active cleansing agents in this motor oil are also designed to particularly clean up any sludge or other harmful substances left behind.
Mobil 1 high mileage is also formulated with active cleaning detergents, which help keep the engine free from any sludge and deposits built up. These additives also help maintain the quality of the engine oil for longer-lasting performance.
Do they provide the engine against burning protection?
Heated engines can cause the oil molecules to evaporate and thus causing a drop in the oil level. The more the oil burns off, the more the fuel is consumed. This means you will have to change your engine oil too frequently. Moreover, increased oil burn-off also leaves the engine unprotected and produces dangerous emissions. It also causes poor performance and low temperature start along with increasing deposits in the engine.
Mobil 1 advanced fuel economy has outstanding low-temperature qualities, which help the engine start quickly while keeping it protected from any harmful deposits. The antioxidants in this motor oil further help reduce any oil burn-off and maintains thermal stability.
Mobil 1 high mileage is an excellent lubricant that promotes thermal and oxidation stability that helps reduce any oil molecules from evaporating even under extreme conditions.
How they protect the engine’s wearing off?
Additives such as anti-wear agents are added into full synthetic motor oils to help minimize any engine wear or tear.
Mobil 1 advanced fuel economy is formulated with a balanced additive component which helps provide outstanding wear protection. The anti-wear agents present in the motor oil prevent any engine wear for mild to severe driving conditions.
Mobil 1 high mileage uses an advanced full synthetic formula that provides exceptional protection to the engine and all the important parts. The anti-wear agents further provide great wear protection, which helps extend the engine’s life.
What about engine seal protection?
Modern technology and additives such as detergents are added to engine oils to help protect the engine seal.
Mobil 1 advanced fuel economy is formulated with active cleaning detergents, which help clean up any sludge left in the engine. Moreover, it protects the engine seal from other damaging deposits too.
Mobil 1 high mileage uses premium seal conditioners which help protect the engine seal from any leaks. Moreover, the detergents in the motor oil also facilitate cleaning and keep the oil-free from sludge and other harmful substances which may damage the engine seal.
Which oil is capable of increasing fuel economy?
You can significantly reduce fuel consumption if your engine works properly and is in good health. Furthermore, oil burn-off protection and prevention of any sludge built up can reduce the level of fuel consumption on a major level.
Mobil 1 advanced fuel economy provides excellent thermal and oxidation stability, which stops oil molecules from evaporating and thus maintaining the oil level. It is known to improve fuel economy by up to 2 percent. The active cleansing agents further prevent any sludge or harmful deposits from building up and keep the engine oil super clean.
Mobil 1 high mileage is formulated with special additives which help protect the engine from boosting performance and engine life. The detergents present make sure the motor oil stays free and clean from dirt and sludge deposits, and the antioxidants help reduce the level of oil vaporization. Thus, the duel consumption is controlled.
Which oil lasts longer?
An engine oil requires to be changed after a certain amount of miles. Luckily full synthetic motor oils offer you more mileage compared to other forms of motor oils.
Mobil 1 advanced fuel economy offers you great mileage before the oil requires to be changed. It gives you about 15 000 to 20 000 miles of protection before an oil change.
Mobil 1 high mileage also offers a good oil change interval. It is specially formulated for vehicles that run over 75,000 miles and offers 10 000 miles before it requires an oil change.
