High Mileage 5W-20 Full Synthetic Motor Oil, 5 Quart, from Mobil 1 (Part No. 120768)
In This Article...
Will 5W-30 work in a Toyota Corolla?
* Recommended viscosity (SAE): SAE 0W-20, 5W-20, or 5W-30 engine oil is advised in severely cold temperatures since SAE 10W-30 or a higher viscosity engine oil may make it difficult to start the engine.
Here is an explanation of oil viscosity using 0W-20 as an example.
The characteristic of the oil that allows for cold starting is indicated by the 0W component of the oil viscosity rating. Engine starting in cold conditions is made easier by oils having a lower value before the W.
The number 20 in 0W-20 denotes the oil’s characteristic viscosity at high temperatures. If the vehicle is run at high speeds or with a heavy load, an oil with a higher viscosity (higher value) may be more appropriate.
Is synthetic oil required for a Toyota Corolla?
Only Solution. Only Toyota cars (apart from 3UR-FBE Engines*) that require 0w-20 synthetic oil have been given the go-ahead for longer oil change intervals of 10,000 miles or 12 months. (You should, though, keep checking the oil level frequently and topping off as necessary.
Can I replace the 5W-20 in my Toyota with the 5W-30?
It is generally not advised to substitute 5w30 oil (or any other oil weight) for 5w20 oil because even a small viscosity change has the potential to harm your engine.
Because your engine was developed with 5w20 oil in mind when it was constructed, all of the parts that come into contact with it must be a specified viscosity after the engine hits operational temperature, or 212.
5w20 oil will have a lower viscosity than 5w30 oil at this temperature; it will flow more easily and with less resistance. When 5w30 is used in place of 5w20, the engine will experience increased oil resistance once it reaches working temperature, which the engine is not built to manage.
If you substitute 5w30 oil for 5w20 when doing so is not advised or authorized by the owners handbook, it could violate your car’s powertrain warranty, impair engine performance, and ultimately harm your engine.
Using the proper oil keeps your engine operating at its best.

Toyota 0W-20 oil is synthetic, right?
Finding the ideal motor oil for your car is more challenging now that there are so many options available. Oil types like OW-20 are currently becoming much more widespread. Why should you use this oil? What is it?
Toyota car owners now favor the new 0W-20 Oil over other types of oils.
The cost of a quart of the pure synthetic 0W-20 oil is approximately $6.36. Although a quart costs quite a bit, it is the best oil you can use in your Toyota.
The use of synthetic oil is spreading. Simply said, it outperforms traditional motor oil in a wider range of driving circumstances and doesn’t degrade as quickly. Toyota advises using it in all of their vehicles, with the exception of select 4Runner/Tacoma and Flex Fuel Tundra/Sequoia models, because it is so well-liked (see: is Synthetic Oil Good or Bad).

Toyota 5W-20 oil is it synthetic?
Compared to the most widely used grades, it aids in improving fuel economy and increasing engine efficiency. The actual savings vary depending on the type of vehicle/engine, the weather, the road conditions, and the viscosity of your present motor oil.
- Fast protection and quick starting in cold weather contribute to extending engine life.
Toyota uses 100% synthetic, right?
For further information on the recommended oil for your specific Toyota vehicle, consult your owner’s manual. Toyota recommends synthetic oil in all of their vehicles and mandates it on some model years.
Better oil to use: 5W-20 or 5W-30?
The two oils are not superior to or inferior to one another. Your engine needs and the type of vehicle are the determining factors.
You should take into account two things while selecting the ideal multigrade engine oil for your vehicle:
- The recommended oil viscosity grade for your engine
- The temperature that your automobile usually operates at (whether you drive in colder temperature or hotter climates)
Even though certain automobiles do provide some variation in engine oil choices, the majority have a suggested viscosity grade. This is due to the fact that engines are built to run on a particular oil viscosity, and changing that could have an impact on the performance of your engine.
Ideally, 5W 30 oil is ideal for drivers who frequent more extreme weather conditions. Compared to 5W-20 oil, it has a higher viscosity index and a wider operating temperature range. In both colder and hotter climes, 5W 30 oil will provide better protection.
For people who reside in colder climates with low temperatures, 5W-20 oil is recommended. It is suitable for light-duty applications and engines with moderate temperature ranges. In cooler conditions, 5W-20 oil offers good start-up performance.
Note: An oil with a high mileage rating may be required for older vehicles (5W-20 or 5W-30). In this instance, the high mileage oil provides the engine with superior friction and engine drag protection at high temperatures.
What happens if I put the incorrect oil in my car?
The engine may seem noisier or start making a ticking noise if you applied the incorrect oil since the parts are working harder to get the engine moving. If the oil is too thick and cannot flow around your engine as easily as it should, this can also be a problem in cold weather, making it more difficult to start the automobile.
Because using the incorrect oil can create leaks, you might see a few oil stains in your garage or under your car, or you might smell burning when driving. Engine parts may not be adequately lubricated if the oil isn’t performing as it should, resulting in friction and the potential for burning the oil. This is unquestionably a red flag that needs to be addressed right away.
The fact that you feel like you need to fill up the automobile more frequently may possibly be related to the oil. Your engine will have to work harder and burn gasoline more quickly if the oil you’ve used is too heavy and thick to function properly.
Definition of 5w20 Vs. 5w30
The engine oil type 5w20 is distinguished by its oil weight of 20 in warm weather and a winter grade of 5. It has a lower viscosity than 5w30. While 5w30 has the same viscosity rating of 5 in the winter, it has an oil weight of 30 in the summer, making it thicker.
Working conditions for 5w20 Vs. 5w30
For use in cooler climates, use 5w20. As it moves swiftly and smoothly to deeper engine components with less friction, it makes it possible for a vehicle’s engine to start up rapidly. It immediately lubricates the components. In contrast, 5w30 performs well in warm environments. Unlike 5w20, it does not thin out quickly when exposed to heat. The engine components are therefore better protected overall when using 5w30 at operational temperatures.
Performance of 5w20 Vs. 5w30
These two engine oils function well in the environments for which they were created. Due to its low viscosity and reduced friction in the engine parts, 5w20 is a champion in colder regions with speedier engine starts. In hotter regions where a thick oil is required to resist the higher temperatures, 5w30 excels. Naturally, the engine will heat up more, necessitating a thicker oil. In colder climates, 5w20 is associated with higher performance and fuel economy, whereas 5w30 is associated with better overall engine component protection.
Your Owner’s Manual
Although it’s really easy, owners manuals are frequently disregarded. To find out the appropriate viscosity of the motor oil you should use, always consult your owner’s handbook. Use the 0W20 and 5W20 variations interchangeably, depending on the weather, if they are both on the list.
Location
Given that both 0W20 and 5W20 motor oils operate in much the same temperature range, it is critical to think about where you will be using the car. The operating temperature range for synthetic oil is -40C to 20C for 0W-20 and -35C to 20C for 5W20 (5W20 synthetic oil). Being aware of these facts means two things:
- If you reside in a region with extremely low temperatures, such as Alaska or Maine, it is preferable to use 0W20 oil.
- In places like Florida when the temperature is above 20C/68F, you cannot use either 0W20 or 5W20.
Viscosity
The motor oil will flow more smoothly the lower the number is. At beginning temperatures, a 0W20 will be more fluid than a 5W20, but both will function similarly at normal engine operating temperatures. Keep in mind that engine oils naturally become thinner during heating and thicken while cooling.
Quality Testing
Any oil brand with the appropriate viscosity grade and the API donut symbol is acceptable. The oil has passed the testing required for SL service, as indicated by the starburst sign.
The API donut indicates that your motor oil passed the current SL service rating test after being tested by the American Petroleum Institute. ACEA (Association des Constructeurs Europeens d’Automobiles) is the counterpart of API in Europe.
Manufacturer Requirements
If your vehicle is substantially loaded, the machine designer would typically advise using an oil that has a high viscosity and is heavy like honey. However, if it moves quickly, a lubricant that can move out of the way and then move back in is preferable.
Fuel Economy
Despite the fact that both 5W20 and 0W20 (0W20 synthetic oil) can be used at 20C/68F, 0W20 is thinner than 5W20 at cold engine temperatures, particularly in the initial minutes after starting your automobile. Because it gives the car slightly higher fuel economy than the 5W20, new models specify it. The 0W20 model satisfies a turbo-diesel engine’s requirements as well.
