Why does Honda use 10W30?

Honda uses 10W30 oil for their vehicles due to several reasons. Firstly, using a slightly thicker oil like 10W30 can provide better engine protection, especially in warmer climates or during the summer months. Thicker oil can help reduce engine wear and maintain proper oil pressure in high temperatures. Additionally, older engines with higher tolerances may benefit from thicker oils to keep oil pressure up, but this is not necessary for modern engines. It’s important to note that using a different viscosity oil than recommended by the manufacturer can potentially harm the engine, as internal oil passages may not be designed to accommodate thicker oils. Therefore, it is generally recommended to follow the viscosity grade specified in the owner’s manual for optimal engine performance and longevity.
It’s worth mentioning that Honda recommends 5W20 oil for some of their vehicles to improve fuel economy and meet regulatory requirements, such as the Corporate Average Fuel Economy (CAFE) standards. However, in hot weather or if driving conditions require it, Honda allows the use of 5W30 or 10W30 oil as specified in the owner’s manual. Ultimately, it is important to consult the owner’s manual for the specific oil viscosity recommended for your Honda vehicle.

What happens if you use 10W40 instead of 10w30?

Think of it this way: both oil grades are good for cold starts. But if you’re in a warmer climate or the engine runs a little hotter, 10W40 is the way to go. If you live someplace colder or the engine runs cooler, the 10W30 works better since it runs a little thinner in cooler temperatures.

Is 10W-30 better for hot weather?

A 10W flows well in cold weather, to protect the engine at start up, but it’s is too thin for use in the summer. A 30 grade oil, thick enough to protect in the heat, was recommended for summer use. Then, multi-grade oils were formulated.

How bad is it to use 10w30 instead of 5W30?

Using 10W-30 instead of 5W-30, however, could make cold starts more difficult. It’s helpful to think of the “W” as standing for “winter.” The lower the oil’s “W” viscosity, the more readily it will flow when cold. In this case, 5W-30 will flow more easily at startup than 10W-30.

Does it matter if I put 10w30 instead of 5w20?

10w30 is a thicker oil than 5w20, especially at higher temperatures. This means that 10w30 may provide more lubrication and sealing for older engines that have more wear and tear. 10w30 may also be harder to start in cold weather, and may increase the oil pressure and fuel consumption of your engine.

What happens if you put 10w30 in a 5w30 engine?

Really cold. It’s nearly the same viscosity at operating temperature, they are both 30 weight oils. But 10W-30 is THICKER at start up, causing oil to flow much slower to all the internals of the engine. It doesn’t really matter until it’s cold.

Is 10w30 or 10W40 better for summer?

So, if you drive in a warm climate — especially more than 32°C (90°F) — or have an engine that runs hotter than others, 10W-40 oil viscosity is a good option. This higher viscosity oil is designed for hotter temperatures and can handle the added heat stress from the environment.

Will the wrong oil damage my engine?

Yes, the wrong engine oil may cause component damage
If the precisely adjusted properties of the engine oil do not match those of the manufacturer’s approvals in the engine, extreme wear or even costly component damage can occur. Errors in oil selection therefore usually become noticeable after just a few kilometres.

Can I use 10w30 instead of 5W20 in my Honda?

It’s always best to use the 5W20 weight that Honda recommended, mainly because the VTEC system on the engine is oil pressure sensitive; a different weight oil will make slightly different oil pressure. So stick with 5W20 in any case. If you like conventional Castrol 5W20, go ahead, you’ll be fine!

Why does Honda recommend 10w30 oil?

Meticulously engineered, the Honda Engine Oil 10W-30 maintains optimal viscosity for efficient lubrication, effectively minimizing friction and maximizing engine component lifespan. This advanced formula ensures improved fuel efficiency and reduced wear.

What happens if I put SAE 10w30 instead of 5W30?

You can use 10w30 instead of 5w30 as long as the vehicle isn’t subjected to cold temperatures for an extended period of time. You want the oil to be pumped throughout the engine as quickly as possible after starting the engine to prevent “cold start damage”.
