Can I put 5W-30 in my car instead of 0W-30?
When it comes to engine oil, choosing the right viscosity is crucial for the health and performance of your vehicle. Many car owners wonder if they can substitute 5W-30 for 0W-30, especially when the latter is specified in their owner's manual. In this article, we’ll explore the differences between these two oils and whether this substitution is safe for your car.
Understanding Oil Viscosity Ratings
The numbers in oil grades, such as 0W-30 and 5W-30, represent the oil's viscosity, or thickness, under different temperature conditions. Here's what the numbers mean:
- The first number (0W or 5W): This indicates the oil's viscosity in cold temperatures. The "W" stands for winter. A lower number means the oil flows more easily in cold weather, which is critical for engine startup.
- The second number (30): This represents the oil's viscosity at operating temperature. Both 0W-30 and 5W-30 have the same viscosity when the engine is warm.
In essence, the main difference between 0W-30 and 5W-30 is how they perform in cold weather. 0W-30 flows better at lower temperatures, making it ideal for colder climates.
Can You Use 5W-30 Instead of 0W-30?
The short answer is: it depends on your car and the climate you’re driving in. Here are some key considerations:
- Manufacturer's Recommendation: Always check your vehicle's owner’s manual. If it specifies 0W-30, it’s because the manufacturer has determined that this oil provides optimal performance and protection for your engine.
- Climate Conditions: If you live in a region with extremely cold winters, 0W-30 is better suited for your car because it flows more easily at low temperatures. However, in milder climates, 5W-30 may perform just as well.
- Engine Wear and Tear: Using an oil with a higher cold viscosity (like 5W instead of 0W) could lead to slightly slower oil circulation during cold starts, which might increase engine wear over time in very cold conditions.
When Is It Safe to Use 5W-30?
In many cases, using 5W-30 instead of 0W-30 is safe, especially if:
- You live in a region with moderate or warm temperatures where cold starts are not a concern.
- Your car is older and not as sensitive to slight differences in oil viscosity.
- You’re in a pinch and 0W-30 is unavailable, but you plan to switch back to the recommended oil at your next oil change.
However, if your car is under warranty, using an oil grade not specified in the manual could void the warranty. Always consult your mechanic or dealership if you’re unsure.
Conclusion
While 5W-30 can often be used as a substitute for 0W-30, it’s essential to consider your car’s specifications, the climate you’re driving in, and the potential long-term effects on your engine. When in doubt, stick to the manufacturer’s recommendation to ensure optimal performance and longevity for your vehicle.

Frequently Asked Questions
What is the difference between engine oil 0W-30 5W-30 10W 30?
The 0W30 oil is thinner at colder temperatures than 5W30. The 5W30 oil is thinner at colder temperatures than 10W30 oil. All three motor oils act about the same at hot temperatures because they are all 30 weight oils when hot. W means winter.
Is 5W-30 OK for my car?
As previously stated, 5w30 is ok, not a particular problem, simply not -as- good/appropriate as 0w30. 0w30 is more expensive, because its more expensive to make, because it requires higher grade ingredients to work, not to fleece people. Yes 5w30 used in other vehicles, but those are different engines.
Will 5W20 hurt a 0W20 engine?
If SAE 0W-20 synthetic oil is not available, SAE 5W-20 conventional oil may be used. However, it must be replaced with SAE 0W-20 synthetic oil at the next oil change.
What happens if I put 5W30 instead of 0w40?
Some cars accept a variety of different oil weights depending on the climate you live in. The 0W-40 will be a little thicker than the 5W-30 that's recommended, which may reduce fuel efficiency somewhat but it shouldn't be the end of the world.
Is it bad if I use 5W-30 instead of 0W20?
While using 5W-30 instead of 0W-20 might not cause immediate catastrophic failure, it can lead to increased wear, reduced fuel efficiency, and potential long-term damage to the engine. It's best to stick with the oil viscosity recommended by the vehicle manufacturer for optimal performance and longevity.
Which engine oil is better, 0W or 5W?
The first number of a multi-grade oil designates the ability for the oil to be pumped and flow at colder temperatures; the “W” stands for winter. Thus, a 0W oil will be able to flow faster and get to critical engine components better than a 5W or a 10W oil; especially in extreme cold conditions and at engine start-up.
What happens if you put 5W30 instead of 0W30?
A 0W-30 grade can operate at much lower temperatures than a 5W-30 as the oil will flow faster thereby protecting the engine at an earlier stage. Some engines are not suited for a 0W-30, always check your owner's manual before adding oil to your engine.
Can I use 5W-30 at high mileage?
One of the most critical aspects of maintaining a high-mileage vehicle is ensuring it has the right engine oil. This is where high-mileage 5W30 engine oil enters the picture.
Can I put 5W-30 instead of 0W20 on my Subaru Outback?
Oil Type & Capacity for Subaru Outback
Like the Crosstrek, the oil for the Subaru Outback needs to be an API classification SN or ILSAC GF-5. Also like the Crosstrek, the Outback engine should be filled with 0W-20 synthetic oil. If synthetic oil isn't available, you can use either 5W-30 or 5W-40 conventional oil.
Is 5W-30 good for hot climate?
5W-30 motor oil, on the other hand, is multi-grade lubricating oil, it will perform the same in a wider range of heat condition. Hence it outperforms the parts better in hot and cold weather due to the additives included in the batch.
