What is Valvoline?


Established in 1886, Valvoline is also known as “The Original Engine Oil.” Currently, it’s under its parent company Ashland Inc. Three popular Valvoline oil types are conventional, synthetic, and blend.

Valvoline offers solutions for all types of engine gear oil, including high mileage and heavy-duty vehicles, and is available in more than 80,000 sites worldwide.

What is Mobil 1?


Mobil 1 is an American company with over 40 years of experience in designing synthetic motorcycle oil, as well as lubricants for airplanes and other vehicles.

When it comes to engine oil, you can’t go wrong with Mobil 1. With innovations that meet stringent Japanese, European, and American standards, Mobil 1’s multi-layer and anti-wear technology provides your engine with extended protection.

Valvoline vs Mobil1

1. Viscosity grades

Viscosity refers to the thickness or consistency of the oil. High-viscosity oils are thicker and flow more slowly.


The right viscosity ensures proper lubrication and protection of engine components. Whether you choose Mobil 1 or Valvoline, both brands offer a good amount of options, as shown below.

Valvoline Full Synthetic vs Mobil 1 Fully Synthetic viscosity grades
SAE 0W16 Mobil 1 5w20
SAE 0W20 Mobil 1 5w30
SAE 5W20 Mobil 1 10w30
SAE 5W30 Mobil 1 15w50
SAE 10W30
SAE 20W50

2. Fuel economy


Mobil 1’s Advanced Fuel Economy 0W-20 full synthetic engine oil is designed to maximize fuel economy. It helps protect the engine for up to 10,000 miles and meets ILSAC GF-6 standards on wear protection.

Valvoline, on the other hand, exceeds the ILSAC GF-6 standard by around 40%. So, in terms of the fuel economy of Mobil vs Valvoline, the latter is a better option.

3. Volatility

The Noack Volatility test is a method used to determine the evaporation characteristics of motor oils. Those with low volatility are designed to minimize evaporation, ensuring they maintain their protective and lubricating properties even in extreme heat.

According to the chart below, Valvoline Advanced has a lower score at 8%, while Mobil 1’s best is around 9.17%. This makes Valvoline oil quality the better option between the two.


4. Longevity


Valvoline recommends different timeframes to change your oil depending on whether it’s Valvoline synthetic blend vs full synthetic. For the latter, changing is necessary after every 7000 miles or 12 months, whereas the former needs replacement every 500 miles.

In contrast, Mobil 1 can last for 10,000-15,000 miles. However, they still require changing after 1 year, just like Valvoline.

5. Price


Between the two, Valvoline is more affordable—most of its products cost $39.99 to $89.99. Meanwhile, Mobil 1 oils will set you back $30 to $115.

Pros and Cons

In this section, we will have a brands comparison between the pros and cons of Valvoline oil vs Mobil 1.

1. Valvoline

  • More options for viscosity grade
  • Offers 40% higher than standard fuel efficiency
  • Better oil volatility
  • Cheaper option
  • Average longevity

2. Mobil 1

  • Several viscosity-grade options
  • Average oil volatility
  • Nearly double the longevity of most brands
  • More expensive option
  • Standard fuel efficiency

Which is Better?

Of the two products, Valvoline leads in almost all factors—it offers better performance, even at extreme temperatures, while being an affordable option. The one factor where Valvoline does not succeed is longevity, given how Mobil 1 can last almost twice as long.

How Does It Work—The Functions of Engine Oil


The insides of your vehicle’s engine are made of many moving parts, which can experience wear and tear over time from friction and high temperatures. This is where engine oil comes in, as it provides lubrication to reduce friction.

Below are a few ways engine oils benefit your cars and motorcycles:

1. Cleaning


Engine oil plays a crucial role in maintaining the cleanliness and performance of your car’s engine. It not only lubricates the engine’s moving parts but also acts as a cleaning agent.

Engine oil contains dispersant additives that help suspend and trap contaminants like dust and metal within the oil, preventing them from sticking to engine components.

2. Cooling


The oil plays a crucial role in dissipating heat generated during operation by absorbing heat from the engine components and carrying it away to the oil cooler located outside the engine.

3. Sealing


Your car’s engine oil creates a dynamic seal around piston rings. As the pistons move up and down the cylinder walls during the engine’s operation, the oil adheres to the cylinder walls, creating a thin lubricating film.

This film helps stops combustion gases from going out to the combustion chamber, ensuring maximum compression and output.

4. Shock absorber


Engine components are always moving and vibrating inside your car. When these components move rapidly, engine oil gets trapped within the gaps and spaces between moving parts, forming a thin lubricating film.

This film acts as a dampener, absorbing and cushioning the impact of vibrations. By creating a barrier between the metal surfaces, the oil helps to dissipate and dampen the vibrations, reducing the transmission of shock through the engine.

5. Rust protection


Corrosion or rust occurs when metal surfaces are exposed to wet surfaces and oxygen. Lubricants, such as engine oil, contain inhibitors that constitute a protective barrier on metal surfaces. It’s this barrier that stops water and air from coming into the exposed metal, reducing rust formation.

Factors to Consider Before Buying Oil

Here are some essential tips to guide you in selecting the appropriate motor oil:

1. Read your car manual


Your car’s manual contains information about the recommended motor oil specifications for your specific vehicle. The manual provides details such as the required viscosity, oil type, and any additional manufacturer recommendations.

Following these guidelines ensures you choose the right motor oil that aligns with your car’s requirements.

2. Determine your driving environment


Consider your driving environment, including the climate and weather conditions in which your vehicle primarily operates. Thinner oils, with lower viscosity ratings, are suitable for colder temperatures, ensuring easy engine startup and proper lubrication.

On the other hand, more viscous oils provide better protection and performance in high-temperature environments.

3. Know your oil types


Synthetic oils generally offer better oxidation resistance, improved temperature stability, and enhanced protection against wear and deposits. However, they can be more expensive than mineral oils.

Consider your budget and the specific needs of your vehicle to determine which type is most suitable. If budget allows, synthetic oil is always the better choice.

4. Standards

Look for oils that carry the appropriate accreditation from the American Petroleum Institute (API) in the US and the Automobile Association (ACAE) in Europe, as it indicates that the oil has met the required performance and quality criteria.

Checking for these standards ensures you choose a reliable and high-quality motor oil for your car.

5. Consider your driving habits and vehicle requirements


Evaluate your driving habits, including factors such as frequent stop-and-go traffic, long-distance highway driving, or towing heavy loads. This can help you select a motor oil that provides optimal protection and performance.

How to Know if My Engine Oil is Bad

Here are some key factors you need to look out for to determine if your engine oil is going bad:


  • Oil Change Light

Your oil change light is your first and most obvious indication. When it starts to turn on, this means there is not enough in your engine.

Use your dipstick to determine your engine oil level. To test, pull the dipstick out of its housing and dip it all the way into the oil tank. If it’s below the ADD line, it’s time to refill the tank.

  • Engine Noise

A creaking or rumbling noise coming from your engine can mean that there’s no lubrication to absorb the shocks coming from the system. Identifying this early can save you from a huge engine problem down the line.

  • Oil has a dark color

Over the course of use, the engine oil will turn dark as it absorbs contaminants like dust and metal. Dark engine oil is a sign that it is past its lifespan and may not absorb more material.
