Both oils have a high-temperature rating of ’40’, making them well-suited for warm conditions. However, they differ mainly in their cold-weather performance, indicated by the ‘0W’ and ‘5W’ in their names. Cold Weather Performance https://cdn.opieoils.co.uk/images/variants/icon/castrol/castrol-edge-titanium-0w-40-a3b4-fully-synthetic-car-engine-oil-1-litre-5.jpg Mobil 1 FS 0W-40 advanced full synthetic engine oil is engineered for the latest gasoline and diesel engine technology (without Gasoline or Diesel Particulate Filters) delivering excellent all-round performance. It provides exceptional cleaning power, wears protection. Mobil 1 FS 0W-40 keeps your engine running like new in all driving conditions. According to the 2020 ford owner’s manual, almost all of their engines must be using a 5w30 motor oil or 0w30 motor oil. Unfortunately, there are no mentions of 0w20 motor oil and 0w40 motor oil in the recommendation list of motor oils used in Ford engines. But both 0w20 motor oil and 0w40 motor oil can be used for all climates or temperatures, but 0w20 motor oil is a better option for hot climates. The fact that 0w40 retains its fluidity when the cold makes it ideal for fuel economy. It provides the much-needed lubrication to ensure the engine parts don’t strain to move. The ease of movement does not require much force; as such, there is low fuel consumption.

If the engine is not clean, It can lead to further engine damage.

The W in most oil-grade alphanumeric systems denotes winter. In winter, where driving environments are poor due to cold, the 0w will work better than 5w as it is less dense. The thinness of the oil makes it effective in reducing friction and easing the movement of the engine parts. Is 0w40 Good For Winter? https://cdn.opieoils.co.uk/images/variants/large/castrol/castrol-edge-titanium-0w-40-a3b4-fully-synthetic-car-engine-oil-4-litres-3.jpg Although it excels in cold conditions, 0W40 also offers strong performance in high temperatures. The ’40’ in 0W40 indicates the oil’s high-temperature viscosity, meaning it won’t get too thin when things heat up. This ensures that even in hot conditions, the oil maintains a stable film to protect engine components from friction and wear. 0W40 vs 5W40

Properties and Specifications

Before making any switch, consult your vehicle owner’s manual for specific oil recommendations. If your manual states that both oil grades are suitable, switching should not be problematic. 2. Is one type of oil better for older cars? https://cdn.opieoils.co.uk/images/variants/medium/mobil/mobil-1-fs-0w-40-advanced-fully-synthetic-engine-oil-20-litres-1.jpg From the SAE numbers, we can tell that 0W-40 oil has a higher number after ‘W’ than the 5W-30 oil. This implies that 0W-40 oil offers better resistance to thinning and thermal breakdown, making it a recommended oil for high temp regions. 3. Suitable Temperature Yes, You can mix two different viscosity oils as long as they are from the same brand. It will be just fine.
