Performance

The Mannol Extreme 5W40 SL/CF oil is designed for maximum engine performance across a wide range of operating conditions. It provides excellent wear protection, even under high temperatures, to keep your engine running smoothly.

This motor oil has been tested to provide a high viscosity index, meaning it maintains a protective oil film between engine components at both low and high temperatures. You can count on stable performance whether driving in freezing winter conditions or during hot summer months.

In industry standard Sequence IVA wear testing, the Extreme 5W40 received a rating of 0.8, far exceeding the minimum requirement of 1.5. This demonstrates the oil's exceptional ability to minimize engine wear, even during prolonged operation.

The advanced formula also delivers great fuel economy benefits. It has a low viscosity rating of 5W-40, meaning it flows easily when the engine is cold, reducing friction and enabling smooth startups. Once at operating temperature, it provides the high temperature protection of a 40 weight oil. This combination helps maximize engine efficiency and fuel mileage.

Overall, the Extreme 5W40 delivers outstanding all-around performance. It protects against wear across a wide temperature range while also optimizing fuel economy. For drivers who want maximum engine protection without sacrificing efficiency, it's an excellent choice.

Pros

• Designed for high performance and racing engines, providing excellent protection even under extreme conditions. The 5W-40 viscosity offers easy cold starts while maintaining stable oil pressure at high temperatures.

• Meets a wide range of specifications and approvals from major manufacturers like Mercedes, VW, Porsche, BMW, and API. This demonstrates the oil has passed rigorous testing across different engines.

• Contains a robust additive package including high levels of detergents to prevent sludge build-up. The synthetic base oils also resist oxidation and thermal breakdown, helping the oil last longer between changes.

• Offers strengthened anti-wear properties to protect highly loaded parts like bearings and valve train components. This minimizes wear even during extended oil change intervals. The oil film strength also reduces friction for added power and fuel economy.

Cons

While the Mannol Extreme 5W40 SL/CF is a quality oil, it does have some drawbacks to consider:

• May not be suitable for all engines: This oil is formulated for gasoline engines, so it may not provide adequate protection for diesel engines. Be sure to check your owner's manual for recommended viscosity grades and specifications. Using the wrong oil can lead to increased wear or even engine damage.

• Higher price point: Synthetic oils like the Mannol Extreme tend to cost more than conventional oils. For some drivers watching their budget, the extra cost may not be justified, especially for older vehicles that don't require full synthetic oil. There are more affordable synthetic blend and conventional oils available.

• Limited availability: Because it's a European brand, Mannol oils can be harder to find in some areas compared to major brands like Mobil, Castrol, and Valvoline. You may need to visit specialized auto parts stores or order it online if your local shops don't carry it. Lack of availability could make it less convenient to purchase.

• May not provide fuel economy benefits: While synthetic oils like 5W40 provide excellent protection at temperature extremes, they do not necessarily improve fuel efficiency compared to lighter viscosity oils. Drivers looking to maximize mpg may want to use a thinner oil during optimal driving conditions.

Overall the drawbacks are minor for most drivers who prioritize engine protection over factors like price and availability. But they are worth acknowledging before choosing the Mannol Extreme as your oil of choice.

Best Uses

The Mannol Extreme 5W40 SL/CF oil is ideal for drivers who want a high performance motor oil that can handle a wide range of temperatures. This oil is formulated for both gasoline and diesel engines, making it versatile for many types of vehicles.

Some specific scenarios where the Extreme 5W40 really shines:

• High performance and sports cars - With its low viscosity, this oil helps maximize engine response and power output even under high stress driving conditions like racing or track days. The advanced additive package provides exceptional wear protection when engines are pushed to their limits.

• Colder climates - The 5W winter grade makes this oil flow readily at start-up in frigid temperatures, while the 40 grade provides sufficient viscosity and oil film strength when the engine is at operating temperature. This combo helps prevent wear during cold starts while maintaining protection at higher temps.

• Towing and hauling - The shear-stable formula fights viscosity loss when subjected to heavy loads over extended driving durations. It keeps oil pressure steady and ensures optimal lubrication for hard-working engines under load.

• High mileage engines - Dispersant and detergent additives help keep older engines clean by preventing sludge and deposit buildup. It also contains seal conditioners to rejuvenate aging seals and reduce oil consumption.

So in summary, the Mannol Extreme 5W40 is a good option for performance enthusiasts, cold weather drivers, haulers, and aging vehicles. The advanced formula provides well-rounded protection that caters to a wide spectrum of demanding driving needs.

Value

The Mannol Extreme 5W40 SL/CF oil typically retails for around £16 for a 1 liter bottle. This puts it at a mid-range price point compared to other leading synthetic motor oils.
