Synthetic Formulation

The Motul 8100 ECO-clean+ utilizes a fully synthetic base oil formulation. Synthetic oils have a number of advantages over conventional mineral oils:

• Improved thermal stability. Synthetics are able to withstand higher operating temperatures without breaking down. This reduces oil oxidation and deposits.

• Better low-temperature properties. Synthetics flow more easily in cold temperatures, allowing for easier cold starts.

• Increased resistance to viscosity breakdown. Synthetics maintain their viscosity grade better over time.

• Lower volatility. The molecules in synthetic oil evaporate less readily than those in conventional oil. This reduces oil consumption.

• Higher purity levels. The refining process for synthetic base oils removes more impurities compared to mineral oil refining.

The synthetic formulation gives Motul 8100 ECO-clean+ high performance capabilities and allows it to provide extended drain intervals. Synthetics also offer superior protection for modern, high-output engines that generate more heat and stress.

ECO-clean Technology

Motul's 8100 ECO-clean+ engine oil utilizes an innovative ECO-clean technology designed to provide exceptional protection for emission control systems. This technology helps keep catalytic converters operating at peak efficiency for reduced emissions.

The key benefit of ECO-clean is its ability to minimize deposits in the emission control system. It helps prevent the buildup of phosphorus, sulfur, and other harmful contaminants on catalytic converter surfaces. By reducing deposits, the catalytic converter can function optimally throughout its service life.

ECO-clean additives make this motor oil fully compatible with catalytic converters and oxygen sensors found in the exhaust systems of most modern engines. Motul uses an ashless formula to ensure the oil does not contribute to catalytic converter poisoning. This enables the emission control system to work as intended and avoid reduced performance or failure.

Overall, Motul's ECO-clean technology allows its 8100 engine oil to deliver robust emission system protection, which is critical for meeting the latest European emissions standards. The oil allows engines to operate cleanly and responsibly.

Additives Package

Motul 8100 ECO-clean+ features an advanced additives package designed to provide excellent engine protection and extended drain intervals. Some key additives include:

• Detergents - Help keep critical engine parts clean by preventing deposit build-up. This enhances overall engine performance.

• Dispersants - Suspend oil contaminants and combustion by-products so they can be drained out during an oil change. This prevents sludge formation.

• Anti-wear additives - Create a protective layer on metal surfaces to reduce friction and wear, especially during cold starts. This prolongs engine life.

• Antioxidants - Inhibit oxidation at high temperatures to prevent oil thickening and deposit formation. This maintains fluidity.

• Corrosion inhibitors - Protect engine parts from rust and corrosion damage from moisture, acids, and contaminants.

• Foam inhibitors - Suppress foaming to enable smooth oil circulation and prevent air pockets that can reduce lubrication.

The advanced additives in Motul 8100 ECO-clean+ allow extended drain intervals of up to 20,000 miles/1 year under normal driving conditions. This maximizes engine protection while minimizing maintenance requirements. The oil withstands high temperatures without thickening or breaking down. Overall, the additives package delivers exceptional performance, protection, and longevity.

Viscosity Grade

The Motul 8100 ECO-clean+ has a viscosity grade of 5W-30. The "5W" refers to the oil's winter or low temperature viscosity rating, while the "30" refers to its high temperature viscosity rating.

A 5W-30 oil like the Motul 8100 ECO-clean+ provides the following benefits:

• Good cold start performance - The "5W" low temperature rating means the oil will flow easily at start-up in cold weather, allowing the engine to start smoothly and preventing wear.

• Good high temperature viscosity - The "30" rating indicates the oil will maintain a protective viscosity film at high operating temperatures to protect engine components from wear.

• Fuel efficiency - 5W-30 oils strike a good balance between low viscosity for fuel economy and high temperature viscosity for protection. Using a 5W-30 can increase miles per gallon compared to thicker oils.

• Meets specifications - 5W-30 meets viscosity specifications for many modern gasoline and diesel engine manufacturers for optimal performance and protection. It is suitable for a wide range of engine types.

So in summary, the 5W-30 viscosity grade of Motul 8100 ECO-clean+ provides excellent cold weather starting, helps improve fuel economy, maintains viscosity at high temperatures, and meets OEM specifications for many vehicle makes and models. The multi-grade formulation protects the engine in all operating conditions.

Performance

The Motul 8100 ECO-clean+ is designed to meet the latest engine oil specifications for modern gasoline and diesel engines. It has been tested and approved against industry standards such as API SN and ACEA C3 for gasoline engines, as well as ACEA E6, E7, E9 for diesel engines.

In real world driving, the 8100 ECO-clean+ provides exceptional performance across a wide temperature range. The synthetic base oils and additives help reduce friction and wear, allowing for smooth cold starts even in frigid temperatures. At high engine temperatures, the oil maintains its viscosity and protects against deposits and sludge buildup.

Drivers report the 8100 ECO-clean+ provides a noticeable improvement in fuel economy compared to conventional oils. This can be attributed to the low viscosity and friction-reducing abilities of the full synthetic formula. The oil flows easily when cold yet maintains a protective cushion at high temperatures.
