We also get from the number that 5w10 has a viscosity index of only 5 at low temperatures, which is half the viscosity of 10w40 at low temperatures. But, this is not applicable everytime as both the oil can sometimes be used in the same engine without any problem. If you use 10w40 in an engine for which 5w30 is recommended, then you will get poor engine performance in winter. We believe that you should never use 10w40 instead of 5w30. One most common type of difference between the two of them is their viscosity. Here are some more articles for you to check out: 20W50 vs 10W40 Oil: Whats the Difference and Which Is Better?

Can You Use 10w30 Instead Of 5w20: External Temperature The lower the number before the "W" in these oils, the thinner the viscosity of the oil. The recommended oil for all Toyota engines is 5w30 motor oil. For instance, 5w30 isnt always recommended in low temperatures for all car models. As a result, there will be a lack of fast lubrication and engine wear and friction. Accidentally Used 5w40 Instead of 10w40: Is It Ok? Considering this much knowledge, we can say, 10W40 is good to go to oil. Thus, 10w40 motor oil is preferable at a higher temperature since its viscosity at a low temperature is pretty high. Related Posts: Can I Use 5w30 Instead Of 5w20 In My Honda? Piston and cooling nozzles require increased oil flow. If you use 10w40 in place of 5w30, it won't perform as well as 5w30 in low temperatures. In addition, using thicker oil like the 10w40 motor oil will also provide the engine parts a lot of lubrication. So, whichever type of oil you use, it is vital to understand the grades first. The difference in their viscosity level almost entirely defines their applications in car models. But in actuality, it finds the thinness as well. Price: 5w30 is more expensive, 10w40 is cheaper. The cold viscosity is referring to the thickness of the oil upon a cold start of the engine. Also, with higher viscosity, it will have a decreased flow rate. It simply implies that choosing motor oil other than manufacturers recommended cars increases its chance of damaging parts. Can I Use 10w40 Instead of 5w30? Will It Hurt the Engine?

If you live in a region or drive in cities with year-round low temps, using 5w30 may be the best option here. 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). 20w-40. There is no mention of 10w40 motor oil in the recommendation list. Can You Buy a Random Brand? 10w40 oils are not made for smaller engines. In summary, what you should know is that 5w30 oils are less viscous and flow easily than 10w40 oils at both high and low temps. But, 10w40 is multi-weighted. In addition, the thickness or viscosity is known as the weight of the fluid. 5w30 has lower viscosity hence it is suitable to use in hot or lower temperatures. Colder oil viscosity is only affected by the first number (with a "w").Dec 30, 2021 Is 10W40 better than 5W40? However, as its number suggests, it is much thinner than 10w40.

Are There Any Situations When You Can Put 10W40 Instead of 5W30? In this article, we will be talking about the differences between these motor oils. While the cold weight isnt significantly different, the difference in the warm weight means that the 5w30 oil will be thinner while running at optimal temperature, which can cause damage to the engine due to insufficient lubrication.
