Motor oil is the lifeblood of your car’s engine, providing lubrication, cooling, and cleaning to keep it running smoothly. But with so many different types of oil available, it can be difficult to know which one to choose. Fortunately, I found the two popular options: SAE 30 vs 10W30. Although both have advantages, it was difficult for me to choose which one was better.
SAE 30 has a higher viscosity and is thicker, providing better protection to the engine in warm weather, but it may not be suitable for colder temperatures. 10W30 is designed for colder temperatures and contains additives that improve engine protection, cleanliness, and fuel economy. It is also less prone to oil consumption, lasts longer, and is more expensive than SAE 30.
Stay tuned, here you will be taught about SAE 30 and 10W30 . It may help you choose the best oil for your vehicle. Let’s explore.

SAE 30 is an excellent motor oil developed for small engines such as lawnmowers and generators. It has a viscosity rating of 30, meaning it is relatively thin and flows easily. SAE 30, such as Briggs & Stratton 30W Engine Oil, protects engines operating in moderate to warm temperatures.
- SAE 30 oil performs well at high temperatures.
- It is a popular choice for older engines with a looser internal tolerance.
- It is generally less expensive than synthetic oils.
- SAE 30 oil can go longer between oil changes.
- It is easy to find and widely available at most automotive stores.
- Poor cold-weather performance.
- The higher viscosity may cause reduced fuel efficiency.
Note: The manufacturer should improve the quality features. It needs to work on its performance in cold weather. Users may face trouble in cold areas starting the vehicle.
Most of the users generally give excellent reviews about the performance of sae30. Almost more than 80% of users give it 5 stars. Its durability, sheerness, and longevity collect excellent remarks.
Sae30 is the best motor oil compatible with almost all small engines. You can use it in boats, lawnmowers, and other equipment. Its performance is satisfactory.
However, some users claimed its color was black, even when opening the pack. Some users also claim it cannot work well after 1 or 2 seasons.
10W30, for example, Valvoline Daily Protection SAE 10W-30, is a popular motor oil recommended for use in cars and trucks. The “10W” designation indicates that the oil has a low viscosity when cold, making it simpler to start an engine in cold weather. The “30” means the oil maintains its viscosity when hot, protecting the engine.
- 10W30 oil can be used at a wide range of temperatures.
- Its thinner consistency improves fuel economy.
- Contains additives to protect engine parts from wear and tear.
- Helps keep engines clean by preventing deposits and sludge.
- It can be found at most auto supply stores and service stations.
- Poor performance in extremely cold temperatures.
- Thins out quickly at high temperatures, reducing protection and increasing engine wear.
Note: It needs improvement in terms of quality. Manufacturers should work on it to make it a better oil for use at cold temperatures.
10w30 has received high praise from many users for its excellent performance. With an impressive 84% of users giving it a 5-star rating, it is clear that this oil has won over many fans.
Users appreciate its sheerness, longevity, and excellent value for money. This oil also improves engine performance and has good strength against extreme temperatures.
However, some users have claimed that it does not function as well as conventional oil. They suggested that there is room for improvement.
Viscosity means the oil’s resistance to flow at a particular temperature. SAE 30 oil has a higher viscosity rating than 10W30 oil. It means SAE 3O is thicker and more resistant to flow.
It protects the engine’s internal parts better by reducing metal-to-metal contact. However, the thicker oil may not be suitable for colder temperatures.
The W in 10W30 stands for “winter,” indicating that it is formulated to perform well in colder temperatures. In contrast, SAE 30 oil best suits warmer climates, where temperatures do not drop below freezing.
The 10W30 oil is designed to have a lower viscosity when cold, allowing for easier engine start-up and faster oil circulation.
10W30 oil offers better engine protection than SAE 30 oil because it contains additives that help reduce engine wear and tear. These additives improve the oil’s ability to resist oxidation and deposit formation, leading to a longer engine life.
The more advanced formula of 10W30 oil also helps reduce engine deposits and sludge. So, it ensures better protection for the engine.
10W30 oil may offer better fuel economy than SAE 30 oil because it is less viscous. It creates less friction within the engine.
Lower viscosity oil reduces drag and helps the engine operate more efficiently, leading to improved fuel economy.
However, the difference in fuel economy is minimal. It is always best to follow the manufacturer’s recommendations for oil viscosity.
10W30 oil contains more detergents and dispersants than SAE 30 oil. It can help keep engines cleaner by preventing deposits on engine components. The detergents in 10W30 oil help to keep contaminants suspended in the oil.
It also prevents them from sticking to engine surfaces and causing damage. The oil dispersants help break down and remove sludge and other debris from the engine. So, 10w 30 may be a better choice than SAE 30.
SAE 30 oil is thicker and may not flow as easily through the engine as 10W30 oil. Due to its viscosity, SAE 30 oil may be more prone to oil consumption. So the engine may use more oil than necessary.
On the other hand, 10W30 oil flows more quickly through the engine and is less likely to be consumed excessively.
10W30 oil contains more additives that protect the engine from wear and tear than SAE 30 oil. These additives protect the engine by preventing the formation of deposits and reducing friction. As a result, 10W30 oil may offer better long-term durability than SAE 30 oil.
The recommended oil change interval for SAE 30 oil is typically shorter than that for 10W30. SAE 30 oil breaks down faster due to its lower viscosity, losing its protective properties. 10W30 oil, with its higher viscosity, can last longer and ensure adequate protection.
SAE 30 oil is compatible with other straight-grade oils, while 10W30 oil is compatible with other multi-grade oils.
If an engine requires straight-grade oil, SAE 30 oil would be a better choice. If you have an engine that requires multi-grade oil, such as 5W30 or 10W40, then 10W30 oil would be a better choice.
SAE 30 oil is generally less expensive than 10W30 oil. It is because SAE 30 oil is a single-grade oil, while 10W30 is a multi-grade oil containing more additives. But the higher price of 10w30 also brings more quality features than SAE30.
In my opinion, it ultimately depends on the climate and the engine’s requirements.
SAE 30 oil may be better for warmer climates, while 10W30 oil is suitable for colder temperatures. 10W30 oil has more advanced additives that offer better engine protection, cleanliness, and durability, but it is expensive. SAE 30 is also an affordable choice if you live in warm areas.
However, following the manufacturer’s recommendations for oil viscosity is always best. It ensures the correct oil change intervals, optimal engine performance, and longevity.
