Is 5w40 better than 5w30?
The difference between 5w30 and 5w40 is that 5w40 has larger viscosity than 5w30. This means 5w30 is better than 5w40.
Is 5w40 good for high mileage?
Mechanics commonly use 5W-40 motor oil to support higher mileage engines because it is thicker under heat than the average oil and will lubricate moving parts better inside the motor that have been worn down due to strain or age.
Is 5w30 good for high mileage?
Amazon Basics Full Synthetic is the best 5w30 oil for high mileage vehicles. This oil should only be used on vehicles exceeding 75,000 miles. This motor oil is formulated for longer drain intervals. It helps in preventing a build-up on drain intervals and preventing rust and corrosion.
Is 5W40 good for summer?
Be happy; 5W40 is great for summer with the added bennie of great cold start specs. As to interval, you can safely go longer but how much longer will depend on the soot load and fuel dilution.
Can I put 5W40 in my BMW?
The Castrol oil that BMW used to spec was midway between a 30 and 40 weight. Anything from 0W30 to 5W40 will be fine if it has the LL-98 or LL-01 rating. You don’t even need that if you are running shorter change intervals.
What happens if you mix 5w30 and 5w40?
Oils are miscible. You don’t need to worry about adding one to the other in any proportion as they will easily form a solution. You can use 1 litre of 5W30 mixed with 5W40 and it will not cause any sort of ill effects to the engine.
What does 5W 30 stand for?
5w30 is a motor oil that is widely used in light-duty petrol and diesel engines. The “W” stands for “winter,” the number preceding it indicates the oil’s viscosity (or thickness) at low temperatures (hence the W), and the number after it indicates viscosity at higher temperatures, when the engine is running.
Can I use 10w 40 instead of 5W40?
The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). However, the main difference between these two engine types is that the 5W40 can work better than 10W40 in very cold places.
