If the engine is a car’s heart beat then fuel and a good engine lubricant is its lifeline. The engine oil you use determines how long your car will serve you. This Royal Purple Vs Mobil 1 comparison review has more.
Good lubricants/engine oil help car owners cut down car maintenance costs because they need fewer oil changes. Royal purple and Mobil 1 are among the most respected top notch motor oil brands for the average car, in the market today. They both have products with a range of viscosity grades some of which give up to 17000 miles between oil changes. This may translate to only one oil change in a year, depending on how far you drive. Their synthetic formula is both thermal stable (meaning the vehicle will not be affected by changes in temperatures) and oxidation stable – thanks to Zinc Phosphorous and other anti-wear additives. This review however, intends to go deeper and discover which of the two products would serve you better.

Royal Purple Vs Mobil 1- How do they compare?
Both products carry the current API and ILSAC engine oil licenses. They also have the GM Dexos 1 – GM’s new global specifications for gasoline engine oils. They both have warranties of up to 5 years. Even though the oil itself does not go bad, the additives used may be time specific. What all these point to is that both Royal Purple and Mobil 1 are quality synthetic motor oils able to protect your engine and support 1, or at most 2 oil changes in a year. How else do they compare?
Oil Change Interval
Mobil recommends oil change intervals for normal driving at 15000 miles while Royal Purple recommends 12000 miles. For both products, this is about a period of one year. Many oil manufacturers recommend changing engine oil every 5000-7500miles. Synthetic oils are however enhanced to even last up to a year without an oil-change. The recommended change interval depends on driving habits. Most manufacturers categorize driving habits into normal and severe and include oil change intervals for these in the car manual. Because the frequency of changing oils directly relates to the amount of money spent on oil changes, Mobil 1 is a better product.
Additives
Royal Purple’s proprietary Synerlec Additive technology and performance filters work against oil foaming and break down, engine wear, corrosion and rusting. This helps manage the oil flow and capture/clean out contaminants. As a result, the car no longer feels heavy or sluggish, its mileage per gallon improves and the ride is silent/smooth.
Likewise, Mobil 1 has a proprietary SuperSyn protection and a blend of high performance synthetic base stocks coupled with an additive component system that ensures overall outstanding engine protection that keeps the engine running like new. All the same, Royal Purple’s Synerlec Additive Technology makes the oil film several times stronger and offers a one off performance filtering solution. This makes it the better product.
Thermo – Oxidation Engine Oil Simulation Test
From this test, Royal Purple has a deposit weight of 10 out of 100 while Mobil 1’s deposit weight is 49 out of 100. The test is used to determine the deposit formed in the oil at high temperatures. Lubricants normally form deposits when heated. Unchecked deposits can slow down efficiency and overall car performance especially with the current increase in turbo charges and the direct fuel injection. Royal Purple forms less deposits and is therefore the better product.
Royal Purple Vs Mobil 1 oil – A Comparative Overview
Mobil 1 Overview
- For best performance, follow the manufacturer's recommendations in your vehicle owner’s manual.
- Fully synthetic formula with supersyn technology helps prevent deposits and sludge build-up to enable long engine life
- Excellent overall lubrication and wear protection performance for all driving styles
- Outstanding thermal and oxidation stability for outstanding performance during the maximum oil change interval recommended in a vehicle’s owners manual
- Enhanced frictional properties that aids fuel economy
For almost 4 decades, Mobil 1 has been renowned worldwide as one of the early innovators of synthetic motor oil. Mobil 1 still scores among the best oils in lubricating and strengthening engines and is popular for its guaranteed durability and efficiency. Mobil 1 5W-30, also known as annual protection full synthetic oil, comes with the proprietary SuperSyn protection which guarantees protection in extreme temperatures. This it does by preventing sludge build-up and deposits in the engine, thus prolonging engine life.
Mobil 1’s proprietary blend also ensures car owners experience boosts in engine smoothness, fuel efficiency and peak performance for up to 15000 miles between changes. Your car therefore runs strong for long. The blend also offers wear protection and overall excellent lubrication to all driving styles. Its enhanced frictional properties help in fuel economy resulting in improved miles per gallon (MPG). Besides, its not just in the high temperatures that your car is covered. Even in low temperatures, the motor oil offers quick starting with ultra-fast protection for the car’s engine and electrical system.
All in all, Mobil 1 has additives that improve its thermal and oxidation stability. It is designed to keep the engine functioning like a new one, by providing excellent wear protection and cleaning power. This improves the overall performance. The motor oil does not however come with performance filters. This means that one has to buy them separately. All the same, Mobil 1 filters are readily available.
Pros
- Longstanding quality brand
- Needs just one oil change a year
- Contains more detergents to help clean engine
- Affordable
Cons
- Have to buy separate extended performance filter
- Good for vehicles that frequently use the highway
- Not much improvement on MPG

Royal Purple Overview
- Better wear protection
- Increased fuel efficiency
- Better protection of the expensive catalytic emission system
- Improved compatibility with fuels containing ethanol
- Superior corrosion protection
Royal purple is an American automotive lubricant manufacturer specializing in industrial, automotive marine and even racing lubricants. As the name suggests, Royal Purple 5W-30 is purple in color, due to the addition of a thermo chromic dye that fades to amber as the oil heats up. The oil has the company’s proprietary Synerlec Additive technology and performance filters which make it stable enough to resist oxidation ultimately producing fewer deposits in the engine. On some occasions, it even completely removes the engine deposits. This technology with its blend of synthetic oils greatly aids in reducing engine heat and wear.
Royal purple Increases power by reducing friction and therefore improves combustion efficiency which translates into more torque and horse power of up to 3-5 percent more than other leading conventional and synthetic oils. Its blend of synthetic oils helps wipe out wear. Since the oil is extremely cohesive it sticks onto the engine surface long after shut down thereby giving it an extra protection during start up. In addition, its patented anti wear additives minimizes any harmful effects that gases may pose. The motor oil is highly compatibility with other mineral and synthetic motor oils that contain ethanol making switching to it from other oils problem-free.
When it comes to filtering, Royal purple high performance oil filters combine advanced micro-glass technology with high capacity optimized flow giving a high performance and filter file. The filter housing is strong and provides extra protection against puncture by road debris. The royal purple filters can provide change intervals 2 to 3 times the manufacturer’s recommendation.
Pros
- Long oil change interval
- Smoother ride
- Increased miles per gallon
- Improved filters incorporated with micro glass technology
- Softens ignition problems especially on cold days
- Good for a range of vehicles
Cons
- A bit pricy
- Containers may leak
