What is 5w30? What is 5w40? Oil flow 5w40 provides higher pressure but less flow. Thickness of 5w30 and 5w40 5W30 is lighter, so it got better fuel consumption. Fuel economy 5w40 has poorer fuel economy.
Application 5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. Cost 5w30 is typically more expensive. In general, 5w30 is a great multi-grade oil for different temperature specters.
It is also more fuel efficient. This oil is most often used in case of higher mileage vehicles as it is thicker than the 30 oil, so will provide better lubrication for the working parts inside the motor that have been wear-off as a consequence of aging or strain.
Author Recent Posts. The best grade of oil for your engine is the grade recommended by the manufacturer. Is it okay to switch grades of motor oil, say, from 5W to 10W? With that in mind, some manufacturers suggest only one grade of motor oil for use in a particular engine, while others set a range of grades based on the climate in which the vehicle is driven.
How about 5W instead of 5W? Again, although both of these examples are 5-weight oil when cold, they have different properties when warm. Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine.
Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life. This reservation of rights is intended to be only as broad and inclusive as is permitted by the laws of your State of residence. View Quotes View my tire cart. Menu Call Us Find Us.

Skip to content In a previous article, we covered low-temperature grade motor oils 0W and 5W Proper Use of Motor Oil 10W30 vs 10W40 When deciding to use one motor oil grade over the other, consider the following factors: Ambient Temperature Although environmental temperature does not add to the heat your engine generates during operation, it impacts oil viscosity.
Fuel Economy 10W oil tends to be more common and widely available, making it more inexpensive to use. Motor Oil Blend Despite being close to negligible, 10W and 10W engine oils still have performance differences. Starburst Certification Go for oil labels with the right viscosity grade and display both the API donut and the Starburst symbol. Viscosity This aspect is vital when choosing between 10W30 and 10W40 motor oils and is the focal point of this read.
Mixing 10W30 with 10W40 You may get different responses when asked about mixing these two oil types. Motor Oil Blends Here are some tips on which oil mixture, 10W30 vs 10W40, to choose, depending on your engine makeup and driving style: Premium Conventional Oil. Conventional oils are becoming less of an option for off-roaders, as this mineral oil type is designed specifically for simple engines and riders with regular driving styles.
Should you fall under this driver category, you are better off with a conventional oil brand with the service level SM or higher. Otherwise, look to the other oil blends if you prefer aggressive riding. Full Synthetic Oil. Because this oil blend has fewer impurities and better extreme-temperature performance, full synthetics are usually compatible with high-tech engines found in race cars and come with a heftier price tag.
These oils are chemically engineered and not meant for all engine types. Both 10W and 10W rarely have full synthetic variants, even for diesel oils. Synthetic Blend Oil. This blend is the most common variant for both 10W and 10W engine oils next to conventional oil types. This blend is mixed with organic oil, which aids in resistance to oxidation.
It is the most economical of the oil blends and is excellent for hauling and off-pavement riding. High-Mileage Oil. High-mileage oils cater to vehicles with engines older than a decade and six-figure miles on the trip odometer. Its seal conditioners help with aging-seal problems, helping restore seal flexibility and covering piston-to-cylinder clearances better.
This formulation also has anti-wear additives that slow down engine wear. Click to see full answer. In this way, what is SAE 40 oil used for? SAE It forms an oil mist during operation, which lubricates all lubrication points that are not supplied with oil via oil splash lubrication.
Its strong adhesive power guarantees excellent emergency lubrication. Likewise, what does oil weight mean? Oil weight is a term used to describe the viscosity of an oil , which means how well it flows at a specific temperature. The Society of Automotive Engineers SAE assigns a viscosity number, or weight , to oil based on its flow at degrees F, which is roughly the standard operating temperature for most motors. The difference between 10w30 and 10w40 is the thickness of the oil at high temperatures, at which 10w40 is thicker than 10w The second number, " 30 " and " 40 " for these oils , is a rating of how effectively the oil pour at hot temperatures.
Multi-grade oils have a polymer that expands when the oil is heated and shrinks when it gets cold to keep the oil working as the viscosity is designated. Straight 40 Weight Motor Oil uses a unique combination of specialty paraffin base oils. This unique combination of base stock oils offers superior film strength.
