Can 5w40 be used instead of 5w30?
If you are racking your brain to choose between 5w30 and 5w40, we recommend you go with 5w30.
However, if it is too expensive or not available for use, you can always go with the 5w40, which is just as good and will not cause any damage to the engine parts..
Is 5w40 good oil?
5w40 is better for starting your engine at low temperatures as it flows more easily in this environment. When the engine is running and hot, the differences are negligible; 5w40 and 10w40 both have high viscosities and are equally effective in protecting against engine wear.
Is Thicker oil better for high mileage cars?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.
What is 5w 40 oil used for?
Ideal for starting engines at low temperatures and effective at high engine temperatures, 5w40 engine oils can be used in most conditions.
What oil is thicker 5w30 or 5w40?
The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30. So, 5w30 is better than 5w40.
Can I mix 5w30 and 5w40 oil?
You don’t need to worry about adding one to the other in any proportion as they will easily form a solution.

Is 5w30 or 5w40 better for winter?
5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.
Is 5w30 better than 10w40?
The main difference between the 5w30 and 10w40 is the viscosity difference at different temperatures. … The one, 5w30, will be able to flow better when the temperatures are low than the 10w40. So at a lower temperature, the 5w30 oil will be the best to protect the engine.
Is 5w30 good for old cars?
In general thinner oils flow faster and lubricate better, and keep the engine parts cooler. using a thicker oil is asking for trouble. So if your original specification calls for 5W30, I wouldn’t change it. … Your driving habit also affect engine performance.
Can I use 10w 40 instead of 5w40?
10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. … Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.
What happens if you put wrong oil in car?
The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. … Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.
Is 5w30 good for high mileage?
1. Valvoline 5w30 – Editor’s Choice Best Synthetic Blend High Mileage Oil. … Having a large market share also allows Valvoline to cater to all niches, but we think that this is the best all-around motor oil for a high mileage engine that we saw.

Is 5w30 good for summer?
It used to be that changing oil weight for summer or winter months was part of proper maintenance. … To combat this, a lightweight oil such as 10-weight was used for cold weather, so it would flow, while heavier 30- or 40-weight oils were best in summer months to prevent the oil from breaking down in the heat.
Will thicker oil damage my engine?
Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.
