5w20 is thinner at lower temperatures, whereas 10w30 is thicker at lower temperatures. 5w20 is better for cold-weather starting, whereas 10w30 is better for sealing action. Light duty petrol and diesel engines use 5w20, whereas large weight carrying engines need 10w30.
Is it OK to use 10w30 instead of 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.
Should I use 5w20 or 30?
You’ll get better protection with 5W 30 oil in cold as well as hotter climates. 5W-20 oil is best for those who live in colder climates with low temperatures. It can be used for light-duty applications, for engines that do not reach very extreme temperatures.
Which is better 10w30 or 5w20?
So, that means when you are comparing 5w30 vs. 10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. … This enables the 5w20 motor oil to reach engine parts quicker and create less drag that reduces fuel economy.Should I use thicker oil in a high mileage engine?
High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. … Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.
What happens if you use 5W-30 instead of 5W 20?
Using 5W-30 instead of 5W-20, you risk damaging your car’s engine because the internal engine components work with 5W-20 motor oil. … It means that both motor oils have the same viscosity under cold temperature. However, 5W-30 has a slightly higher viscosity at 212 degrees Fahrenheit than 5W-20.
Can I put 10w30 in 5W-30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
Is 5W 20 oil synthetic or conventional?
Is 5W20 Oil A Synthetic Oil? 5W-20 oil is available as conventional and synthetic variants. 5W-20 conventional oil is made out of refined crude oil and several additives. It provides adequate performance at normal operating temperature and is recommended for engine protection and lubrication.What is the difference between OW 20 and 5W 20?
Although 5W20 and 0W20 (0W20 synthetic oil) can be used at 20°C/68°F, 0W20 is thinner than 5W20 with cold engine temperatures, especially during the first few minutes after you start your car. New cars specify it because it gives the car a bit better fuel economy compared to the 5W20.
Is 5W 20 thicker than 10w40?So the 5W-20 indicates a thin oil that is great for cold climates, but it does becomes very thin at hotter engine temperatures. The 10W-40 indicates that the oil flows reasonably well at cold temperatures, yet does not get much thinner even when very hot.
Article first time published onIs 5w20 good for summer?
5W20 yeah it is like water, good for winter, but not as good in summer, when it gets 110F. Although 5w20 is like water, but it is holding together.
Is 5w20 thicker than 10w30?
Whether the oil is thicker or extra thinner, it specifies the type of engine it is suitable for. There are hundreds of oils but 10w30 and 5w20 are the most common of all. The 10w30 type is the thicker one and 5w20 is the thinner.
Can you mix 5w20 and 10w30 oil?
It should be fine, considering the temps, and that the suggested oil viscosity is usually 5W-30, so two quarts of 5W-20 and three of 10W-30 probably come pretty close to some viscosity around 5W-30.
Is 10w30 good for high mileage?
Mobil Clean High Mileage 10W-30 is designed for vehicles with more than 75,000 miles. Its advanced formulation helps protect seals and prolong engine life. … These oils protect against sludge and engine rust and corrosion under high and low-temperature operating conditions.
What oil is best for old engines?
- Pennzoil High Mileage Conventional Motor Oil. …
- Castrol GTX Part-Synthetic High Mileage. …
- Valvoline MaxLife High Mileage Synthetic Blend. …
- Mobil1 High Mileage Engine Oil. …
- Amsoil Premium Protection Motor Oil.
Which is better high mileage oil or synthetic?
High mileage oil is designed for vehicles with more than 75,000 miles. … As a rule of thumb, most new cars require synthetic oil. Older cars generally run well with conventional oil, unless your vehicle has more than 75,000 miles on it, in which case high-mileage oil is recommended.
Can you use 10w30 oil in a generator?
Ultimately though, 5W30 or 10W30 are fine in most cases, for most vehicles and generators. Likewise, you’ll often find that using either mineral or synthetic oil is fine. You can even mix the two!
What is the difference between 5w30 and 10w30?
Both the oils have similar viscosity at 100 degrees Celsius but 5w30 grade oil will thicken less than 10w30 grade oil in cold climate. This means 5w30 grade oil will flow effectively in low temperatures, whereas 10w30 oil will flow effectively in high temperatures because of the smaller temperature window.
Is 5w20 good for high mileage?
While both 5W20 and 5W30 motor oils are suitable for high mileage engines, the best viscosity type for your vehicle depends on how the manufacturer designed the engine. Using 5W30 when it is advised that you use 5W20 can result in your vehicle not getting good fuel economy.
What car uses 5W 20?

Can I use OW 20 instead of 5w20?
The 0W or 5W refers to the pumpability in cold temperatures. Therefore, a 0W would flow more easily than a 5W and could be an acceptable substitute. Thus, it is suitable to use a SAE 0W-20 as a replacement for SAE 5W-20 application. **Offers same protection as 5W but also provides faster flow and better fuel economy.
Is it OK to use 5w20 instead of 0w20?
