Which is better, 5W30 or 5W40 Toyota?
When it comes to maintaining your Toyota, choosing the right engine oil is crucial for optimal performance and longevity. Two of the most commonly recommended oils are 5W30 and 5W40. But which one is better for your Toyota? In this article, we’ll break down the differences between these two oils and help you make an informed decision based on your vehicle's needs and driving conditions.
Understanding the Basics: What Do 5W30 and 5W40 Mean?
The numbers and letters in oil grades, such as 5W30 and 5W40, represent the oil's viscosity and performance in different temperatures. Here's a quick breakdown:
- 5W: The "5W" indicates the oil's viscosity in cold temperatures. Both 5W30 and 5W40 perform similarly in cold weather, ensuring easy engine starts and proper lubrication during winter.
- 30 vs. 40: The second number (30 or 40) represents the oil's viscosity at high operating temperatures. A higher number, like 40, means the oil is thicker and provides better protection under extreme heat or heavy loads.
In essence, both oils perform similarly in cold weather, but 5W40 is thicker than 5W30 when the engine is hot.
When to Choose 5W30 for Your Toyota
5W30 is a versatile oil that works well in a wide range of temperatures and driving conditions. It is often the manufacturer-recommended oil for many Toyota models. Here’s why you might choose 5W30:
- Fuel Efficiency: 5W30 has a lower viscosity at high temperatures, which can reduce engine drag and improve fuel economy.
- Moderate Climates: If you live in an area with mild to moderate temperatures, 5W30 is an excellent choice for maintaining consistent engine performance.
- Manufacturer Recommendation: Always check your Toyota’s owner’s manual. Many Toyota models are specifically designed to use 5W30 for optimal performance.
When to Choose 5W40 for Your Toyota
5W40 is a thicker oil at high temperatures, making it ideal for certain driving conditions and vehicle requirements. Consider 5W40 if:
- High Temperatures: If you live in a hot climate or frequently drive in extreme heat, 5W40 provides better protection against oil breakdown.
- Heavy Loads: For towing, hauling, or driving in mountainous regions, 5W40 offers superior lubrication and protection under stress.
- Older Engines: If your Toyota has high mileage or an older engine, 5W40’s thicker viscosity can help reduce oil consumption and protect worn engine components.
Final Thoughts: Which Oil Should You Choose?
The choice between 5W30 and 5W40 ultimately depends on your Toyota’s specific needs, your driving habits, and the climate in which you drive. For most Toyota owners, 5W30 is the go-to option due to its balance of performance and fuel efficiency. However, if you frequently drive in extreme conditions or have an older vehicle, 5W40 might be the better choice.

Frequently Asked Questions
Which engine oil is the best for Toyota?
Mobil 1 is the recommended by Toyota in general. It's also the one they use in their nascars Your Manual should say 0w-16 but 0w-20 can be used. You really shouldn't need to even put in oil until after 3000 miles, and even then you wouldn't need an oil change until much later.
What oil does Toyota use from the factory?
The zero w20 oil is recommended by Toyota for all of their vehicles.
What is 5W-40 oil used for Toyota?
Toyota Motor Oil Synthetic SAE 5W-40 is a developed specifically for Toyota vehicles synthetic motor oil. His innovative additives protect your engine against wear effectively. Toyota Synthetic 5W-40 meets or exceeds the specifications of API SM / Cf and ACEA A3/B3.
What type of oil is better for high mileage cars?
High Mileage Synthetic Oils are specially designed for high-mileage vehicles that require synthetic oils with extra seal conditioner providing more protection to worn seals, which can mitigate leaks in high-mileage engines.
What are the benefits of using 5W40?
5w40 Engine oil flows well at low temperatures. This can enhance cold weather starting and engine wear. Synthetic 5W40 oil lasts long. Its longer oil change intervals save time and money on the long term.
Is 5W40 better than 5W30 in summer?
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.
Can I use 5W40 instead of 5W30 Toyota?
In most cases, 5W40 can be used instead of 5W30. Although it won't hurt your engine, it can probably affect the oil consumption in the car. However, most modern cars and trucks use variable valve timing and lift is controlled by oil pressure.
Is 5W40 oil good for hot weather?
Generally, 5W-40 oil is suitable for: Cold temperatures: Down to approximately -15°F (-26°C), though it can vary based on the specific formulation and manufacturer. High temperatures: Up to around 100°F (38°C) or higher, making it suitable for warmer climates and high-performance engines.
Is there a big difference between 5W30 and 5W40?
5W30 engine oils has a narrower temperature range then 5W40. 5W30 is suitable for operating temperature between -25°C and 25°C, and 5W40 has a range of between -25°C and 35°C. In terms of oil flow, 5W30 has greater flow than 5W40. However, for providing higher pressure, 5W40 is superior.
What happens if I mix 5W30 and 5W40?
We do not recommend you mix your car engine oil as different fluid contain different properties and chemicals which my mix together. This could reduce or make the properties irrelevant in the purchased oil, in turn losing all the benefits of more expensive engine oil.
