It is because not every part of the car, especially the engine, requires the same level of thickness or viscosity. The letter w also refers to winter or low temperature. In this garden gild guides well discuss the following:if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'gardengild_com-box-4','ezslot_13',122,'0','0'])};__ez_fad_position('div-gpt-ad-gardengild_com-box-4-0'); Any electrical machines, vehicles, or motors are runner by oils. The thinner motor oil like 5w30 will be providing less friction in the engine. The only recommended use of 5w30 is when temperatures are exceptionally low or freezing. They are more useful for larger engines with special viscosity requirements, but the case is different for 5W30. If you use 10w40 in an engine for which 5w30 is recommended, then you will get poor engine performance in winter. With its lower viscosity, 5w30 flows better at low temperatures. This is because a 5w30 oil would flow more easily in low temps than 10W30 or 10w40. So, if you are driving your car in a colder place, this thin oil is the best choice for you. But to answer the question, you can use a 5w40 motor instead of a 10w40 motor oil. You must have heard of the Honda oil, Read More Who Makes Honda Oil Filters? Therefore it protects better than 10w40 these parts working under extremely adverse conditions, especially in the summer heat. OTOH, the oil has a pour point of -39 (F and C are the same at -40), and will still pump with ease. The highly viscous nature of 10w40 will not allow the engine parts to move freely. This depends on so many things. 5w30 is less viscous while 10w40 is more viscous. Meaning, 10W-50 motor oil acts like an SAE 10W weight oil under 0C (32F), and an SAE 50 weight engine oil at 100C (212F). But, it can be used for temporary periods as the damage is always due to the long-term application. In some rare cases, 10w30 may cause engine overheating in extremely cold temps. Whats the Difference Between 10W40 and 5W30? The first number in the name of the oil represents the viscosity of the oil when cold. Some parts of the car need a thinner film to protect it from external influences, while others need a thicker film. Because the gasoline in 5w30 is thinner and more able to reach the tough parts of the engine than the fuel in 10w30, 5w30 is more efficient and less viscous. It is a thinner type of oil that allows running the oil inside at a cold temperature where oil jamming is a significant concern. 15w40 vs. 10w30 Toyota But you can also bypass such conditions with 10w40, as it continues to provide good performance even at 32F. But these numbers can sometimes be misleading. The 10W40 will just work well with your motorbike. 40 is generally good for all around use. So, it will face less friction with the engine parts and get a boost in fuel efficiency. Youre okay to switch oil thickness as long as you dont hear any knocking or new noises coming from the engine. However, these differences are not noticeable in normal temperatures. 5w30 oils are lighter than 10w40 oils, but they are recommended (each) for different situations. After 100,000 miles, it is wise to change to 10w40. Which oil is thicker 5w30 or 10W40? Oil viscosity refers to the density of the fluid and is measured using water as the standard viscosity level. If you need a 10w-40, you can use 5w-40. This will give you oil that works great in cold temperatures but not warmer temperatures. When you mix oils, you can lower or raise the viscosity, depending on the amount of oil of the same brand. Thus, some may perform better than the oil depending on the additives included in the formula. When the engine is cold, 5W has a lower viscosity and is healthier for the engine. bobistheoilguy.com, autocareaids.com, forums.overclockers.co.uk, theydiffer.com, pakwheels.com, blog.zeuspng.com/, forums.anandtech.com, motoraudit.com, quora.com, itstillruns.com, lubricants.totalenergies.com, Copyright 2023 YourGreatCar.com | Powered by Astra WordPress Theme.
