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 5W-30 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.
How do I choose the right oil weight?
Oil gets thinner as it gets hotter. To determine the correct viscosity for an application you need to know the operating temperature of the oil in that application. Engines that run high operating oil temperatures require higher viscosity oil. Engines that run low oil temps require lower viscosity oil.
Is 5W-30 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.
Is 5W or 10W better for summer?
Answer: There is absolutely no need to switch to 10W-30 motor oil in the summer if 5W-30 is an acceptable grade for your engine. ... Remember also that a 10W-30 and 5W-30 are essentially the same viscosity at operating temperature, so there is no tangible advantage switching over to 10W-30 for summer driving.
Is 30 weight oil the same as 10w30?
SAE 10w30 oil has 10w thickness at low temperatures, but SAE 30 is at high temperatures. ... In the straight SAE, 30 doesn't and can have immense Viscosity and helpless pumpability at low temperatures. As SAE 10w30 is not thick in low temperature, while SAE 30 is in high temperature.
Is it OK to switch from 5w30 to 10w30?
The oils only differ in cold weather viscosity. If you never see temperatures below zero F then either 5W30 or 10W30 is fine. If winter temperatures are regularly below 0 degrees F then 5W30 is what you should run and you can run it year round if the 30 weight is good according to your owner's manual.
When should I use 20w50 oil?
20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.
Can I use 10W30 instead of 15w40?
Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. ... High quality 10W-30 oils can perform as well, and better than industry-standard 15W-40 oils.
Is 5W30 good for summer?
5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts.
What happens if you put 10W40 instead of 5W-30?
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.
Can you put 10w30 in 5w20?
Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won't spray your lower cylinders for an extra second or so on each cold start.
Is it bad if I put 5W-30 instead of 5w20?
Can You Use 5w30 Instead Of 5w20. It is not recommended. Although they both have the same winter rating of 5, the thickness (viscosity) of 5w30 is a bit higher than 5w20. That means your engine's at stake for using the high viscosity oil.
What does 10W30 mean?
Answered January 07 2020. The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.
What happens if you put 10W oil in 5W?
With temperatures going down to 20F a 10W oil will not be an issue. ... There is a small benefit of using a 10W instead of a 5W oil in that the 10W will normally have less viscosity improvers in it. Viscosity improvers help the oil behave "thicker" at higher temperatures, but they do not actually provide lubrication.
Is 10W 30 thicker than 5W 30?
So both the oils 5W–30 and 10W–30 have exactly the same viscosity (SAE 30) when your engine is running, and will perform in the same way. However, the 10W–30 oil will be thicker (higher viscosity) than the 5W–30 when it is cool.
