Helps Prevent Engine Breakdown

10w 30 is thicker in texture. The more thick the coating layer, the more durable the resistance will be. 10w 30 is made out of enhanced anti-wear additives that delivers thicker and more long lasting layer of anti-wear shield to help the breakdown and sudden engine failure.

5w 30 is quick to flow compared with 10w 30. Thus, it allows longer intervals in between pulling in break and acceleration. 5w 30 is especially formulated to run in cold weather with its thin texture, thus, it is quick to response and easy to rush.

Prevents Leakage

10w 30 comes works as a oil conditioner. Due to its thick viscosity it helps the engine and protects it against sludge and other harmful deposits with its pristine seal conditioning. the premium seal conditioning also helps the oil to treat the engine well and prevent leakage.

On the other hand, unlike 10w 30, 5w 30 focuses more on the high resistant viscosity and prevents thermal breakdown.

Improved Anti-wear Additives

Most of the oil requires a special sort of fuel injector cleaning but thanks to 10w 30 that comes with adhesive cleaning agents and includes a given detergent base. It’s an oil but works both as a cleaning and lubricating agent that helps the engine from producing further sludge and passageways remains.

Protect Against Sludge

10w 30 has superiors antioxidants unlike many other oil fuel in the market. Thus it is quick to flow and rushes to the rescue in rare cases of motor oil breakdown. The quick flow allows a zero sum game that also resist against the sludge formulation.

5w 30 is quick to flow an helps reduce exhaust emissions due to friction. One of the vital goal a fuel oil must meet is to prevent the engine from noise and vibration. The constant effort not just creates friction but also can result in the untimely expiration of the engine. But owing to 5w 30 which is proven to reduce friction and deliver less engine wear.

Thus it takes more effort and time pumping the oil through out the engine to flow through. 10w 30 doesn’t transfer heat like 5w 30 oils which is much thinner. As a result, the temperature level rises, arousing the possibility of engine breakdown and the build up of harmful sludge due to hastened chemical.

Which one is Better?

The differences between these two oils are rather insignificant. Yet while driving, a slight change can result into a massive affect. That’s why consideration is a must. With 10w 30 being the thicker oil no damage will be done. In a simplified answer, 5w 30 is ideal for cold climates as it is especially designed to conduct in low temperature. Nevertheless, 10w 30 being the more denser oil is good for riding in low temperature.

Are They Interchangeable?

The answer straight off is “YES” they are interchangeable. But one has to abide by the temperature chart handed over by the manufacturer company that comes along with the manual. To be exact, these oil has the same sort of operating style with different ideal temperature point.


Both these oil are adequate. With 5w 30 having the rating of 4.7 and 10w 30 with the rating of 4.8 out of 5 there isn’t much to debate about. It’s only the weather fact you have to bear in mind while buying any of these two.
