Say your engine needs 30-weight oil when it is running at operating temperature. Well, 30-weight oil will work perfectly well when your engine is warmed up. But when you go to start it on a cold winter morning, that 30-weight oil is considerably thicker and has a hard time moving when you turn the key.
Is it better to use 5w30 or 10w30?
5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 is more suitable for commercial vehicles and other cars with heavy load engines.
Which is better 10w30 or 10W40?
The higher the number, the more viscous or thicker, the oil is at higher temperatures. 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.
Is 5w30 or 10w30 better for winter?
10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.
What is the difference between 10w30 and 20W 40?
20w 40 is a thicker oil when compared to the original 10w 30 oil. So 10w 30 oil is going to flow better than 20w40 oil when you initially start it and also run it. If the oil flows better the better the oil will lubricate and protect engine parts.
Is it OK to use 5w30 instead of 10w30?
Can you use 5W-30 instead of 10W-30? Absolutely yes for car engines, 5W-30 is usually synthetic and superior to 10W-30. Both have the same viscosity at the operating temperature of an average car engine. 5W has lower viscosity when cool and is considered better for the car engine during engine start.
What happens if you use 10w40 instead of 5w30?
If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
Is it OK to use 10W40 instead of 10W30?
Similarly, SAE 10W-40 motor oil performs well in cold weather conditions. It has the same low-temperature limits as the 10W-30 but is better in higher temperatures. Either 10W30 or 10W40 for summer use is fine; however, 10W-40 motor oil will better protect your engine.
Does 10W40 hurt 10W30 engine?
If you were to put 10W40 in an engine designed for 10W30, the “thicker” oil would lead to friction in the engine and an increased load on the oil pump. The car would have to do more work to get the oil around the engine block.
Can I use 20w50 instead of 10W40?
Using an oil of a higher viscosity as you mention, 20W-50 instead of 10W-40 can actually cause a higher rate of fuel consumption due to the fact that there is a greater resistance to flow. This greater resistance to flow can also increase engine operating temperature.
Can I use SAE 30 instead of 10w30?
No, SAE 30 is a single viscosity oil. 10w30 is multiple viscousity. Recommended engine oil viscosity changes with temperature because natural oils change viscosity with temperature. A SAE 30 oil will thin out at higher temperatures.
Can I use 5w 20 instead of 5w30?
5W-20 oil, being the lower viscosity oil (thinner oil) than 5W-30, might help boost your fuel economy. And although you may not notice a vast difference, it does add up over time. However, remember that you should always use the motor oil recommended for your car by your engine manufacturer or mechanic.
Can I use 5w40 instead of 5w30?
There’s not going to be much functional difference between a 5w-30 and 5w-40 as there’s a lot of functional overlap in the recommendations. The lower weight might yield better efficiency under light load operating conditions, but higher weight might yield better protection under higher load operating conditions.
Can I use 20w40 in splendor?
Yes. Get good Mineral oils. 20W40 Grade. the above mentioned oils are very good and will lasts up to 2000kms.
Is it OK to use 20w40 instead of 10w30?
20w40 is thicker at high temperatures than 10w30 It is desirable for lubrication at operating temperatures to be high. 20w40 is better than 10w30 at normal operating conditions.
What happens if I use 20w50 instead of 10w30?
The main reason for using 20w50 is to slow down oil burning. If this is the case, using 10w30 would speed up the burning. I have had oil burners before, and used 20w50 in the summer, with no problem. But, your car will be hard to start in very cold weather with 20w50.
Should I use 5W or 10W oil?
It’s helpful to think of the “W” as standing for “winter.” The lower the oil’s “W” viscosity, the more readily it will flow when cold. In this case, 5W-30 will flow more easily at startup than 10W-30. In fact, some automakers allow you to switch to a lower viscosity oil depending on weather.
Can I mix 10w30 with 5w30?
No- you wont get the desired output by mixing these two oils. Because , both have different grades, 5w30 is more light and the density is less , and is intended for light usage (scooters). Whereas a 10w30 is a higer grade with more density and suitable for more higher capacity engines.
Which oil is heavier 5W or 10W?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
Should I use heavier weight oil high mileage car?
Older cars with high mileage should typically be serviced with thicker oil. The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Your engine will last longer if you use thicker oil.
Is 10w40 good for high mileage?
Mobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars.
Is 5W30 good for high mileage?
5W-30 motor oil is the top viscosity recommendation by automakers over the past four decades for use in many vehicle types. Furthermore, high-mileage 5W-30 motor oil is specially formulated for late model vehicles or newer vehicles with over 75,000 miles/120,000 kilometers.
