The Redex 10W-40 being reviewed here is a part-synthetic motor engine oil suitable for petrol engines. Motor oils like these are essential for proper functioning and longevity of car engines. The numbers 10W-40 denote the viscosity grade of the oil which is suitable for a wide range of temperatures.

This review will specifically look at the 2 litre bottle of Redex's 10W-40 part synthetic engine oil. We'll go over the key specifications and benefits of using this oil, who it is best suited for, customer reviews and an overall assessment of the pros and cons of this product.

Specifications

Redex RMTN0007A is a 10W-40 part synthetic motor oil that meets key industry specifications for gasoline and diesel engines. The 10W-40 viscosity rating means this oil has characteristics of both a 10 weight oil and a 40 weight oil.

The 10W refers to the oil's behavior at cold temperatures. Oils with a lower cold rating, like 10W, allow for easier flow at startup in cold weather. The 40 refers to the oil's viscosity at high operating temperatures. Higher numbers indicate thicker oil that maintains a protective layer between engine components at higher heat. So 10W-40 provides a balance of cold flow and high temperature viscosity.

Redex RMTN0007A has a part synthetic formula containing some synthetic base oils blended with conventional mineral oils. This provides enhanced performance properties compared to a conventional oil.

This motor oil meets API SN and ACEA A3/B3/B4 specifications for gasoline and light duty diesel engines. These certifications indicate the oil has passed rigorous testing for areas like wear prevention, deposit control, oxidation resistance, and fuel economy. Overall, the key specs make this oil suitable for a wide range of engine types and driving conditions.

In addition to the RMTN0007A, the Redex RMTN0010A 5w30 C3 Fully Synthetic Engine Oil for VW Audi Seat Skoda - 2 Litre is an excellent choice specifically formulated for VW, Audi, Seat, and Skoda vehicles. This fully synthetic engine oil provides superior protection and performance in a variety of conditions. The 5W-30 viscosity ensures optimal engine efficiency while reducing emissions. Its C3 specification means it meets the requirements for extended service intervals, making it perfect for modern diesel engines equipped with particulate filters.

Checking Oil Levels

It's important to regularly check your engine's oil level to ensure there is sufficient oil. This should be done once a month or as per your vehicle's maintenance schedule. Park your car on a level surface and wait 5 minutes for the oil to drain into the sump. Pull out the dipstick, wipe it clean, then reinsert fully and pull back out to check the level. It should be between the minimum and maximum markers. Top up if required.

Topping Up/Changing Oil

When topping up or changing the engine oil, refer to your vehicle's manual for the correct specifications and viscosity. Redex 10W-40 is suitable for many vehicles. Ensure the engine is warm before draining old oil completely. Replace the drain plug, then add fresh oil slowly, allowing time for it to drain into the engine. Check the dipstick to ensure you have reached the proper level, and replace the cap securely before running the engine.

Disposal of Old Oil

Old engine oil can be harmful to the environment so should be disposed of properly. Do not pour it down drains or onto the ground. Many auto part retailers offer free recycling of used oil. Alternatively, contain it in a sealed container and drop it off at a waste management or recycling center that accepts oil.
