With the characteristic of a component that has an essential influence on all activities of vehicles in general and cars in particular, the engine and internal components will have to operate continuously with high intensity.
That leads to regular maintenance to ensure the engine runs smoothly and to limit errors and serious problems that may occur. When it comes to caring, it would be a big mistake not to mention lubrication.
But on the market today, 75w85 vs 75w90 are the two most popular options that users often use. So what is the difference between the two products, and which oil is the best choice? Find out in the article below.

About 75w85
75w85 is the name of a quality engine oil with a composition suitable for many purposes and many different vehicles. Because the main formula of this oil is organic compounds based on polyol esters with moderate viscosity instead of the more mucilaginous ones like many other products.
With the VI viscosity level, 75w85 can easily penetrate the engine’s internal components to lubricate and reduce friction in the most effective way.
At the same time, the correct film thickness also helps the product to operate stably without worrying about burning or coagulation when working in areas with harsh weather conditions.
The most typical are hot and humid tropics or cold, year-round snow-covered regions. To provide outstanding protection as well as lubrication for the parts in operation.
In addition, additives such as Bo and Chlorine also play an essential role in stabilizing the performance and enhancing the lubricating ability of the product. Not only that, but these components also perform another function of the 75w85, which is to create antifoam and rust-resistant films.
About 75w90
Like 75w85, 75w90 is also an engine oil of high quality and suitable for various uses. But with 75w90, you will enjoy an engine oil with a high concentration of constituents that give the product an impressive viscosity.
With such a high viscosity oil, you won’t need to worry about the adverse effects of friction occurring during engine operation. Not only that, the shear resistance of this lubricant is also significantly different from many other similar products.
In addition, 75w90 also contains several additives such as Bo, Chlorine, and especially Phosphorus to shape and support the oil in many different jobs.
Because of the possession of such a quality additive, this lubricant allows the parts to run smoothly and helps us treat rust stains and prevent foaming.
The starting time of the engine will also be reduced if we use this oil for lubrication. Along with that is the ability to avoid car won’t start right away after getting gas.
Similarities Between 75w85 vs 75w90
Basically, the 75w85 and 75w90 have similarities in many different aspects, from components to uses and operability.
Ability to operate in cold environments
Both 75w85 and 75w90 are suitable for use in weather conditions such as snowfall or the too-low outside temperature. Meanwhile, many other lubricant products perform poorly or even freeze if operated in cold conditions.
Therefore, these two products are always the number one choice if you travel in cold areas and do not want to face too much trouble with your vehicle. However, the ability of each oil sample to operate in a hot environment is different, not the same as in a cold climate.
Auxiliary ability
Not only does it serve as a quality lubricant, but both 75w85 and 75w90 possess a variety of additional capabilities to enhance vehicle performance and stability.
Anti-rust additives are included in the two products to help prevent the vehicle’s pipes and fluid transport mechanisms from rapidly degrading. In addition, the annoying air bubbles will no longer have a chance to exist when we use 75w85 as well as 75w90 for our car.
Good compatibility
The social structure with common organic substances, 75w85 and 75w90, is compatible with many other lubricants, especially oil in intercooler pipe. This also means that you can mix these two products with other substances to get the right mixture for your needs.
Difference Between 75w85 And 75w90
Of course, apart from the apparent similarities, there are specific differences between the 75w85 and 75w90. These are also the key points that you need to pay attention to if you choose a suitable product.
Distinctiveness
The most obvious difference that makes it possible to distinguish between 75w85 and 75w90 is the density and viscosity that each product possesses.
Basically, w85 and w90 have many similarities in composition, but w90 manufacturers add some special additives and change the amount of base oil.
And this difference has resulted in quite apparent changes in the density of this lubricating oil. Since then, the viscosity of 75w90, one of the performance evaluation criteria of lubricating products, has increased markedly compared to 75w85.
Heat resistance
We can see that the performance of the two products in cold environments is equal.
However, when it comes to areas that tend to be hot and sunny, it is clear that the 75w90 with a higher viscosity will have better performance and stability than the 75w85.
This does not mean that we cannot use the 75w85 in hot places. Instead, you need to consider and evaluate carefully before using it to ensure stability.
Auxiliary performance
It must be that both products can support the operation and maintenance of the engine’s internal components.
However, in fact, the year difference of 75w85 is somewhat lower than that of 75w90. Many reasons can lead to this difference, the most obvious of which lies in the composition of these two lubricants.
Frequently Asked Questions
Can I substitute 75w85 for 75w90 and vice versa?
Of course, you can ultimately use 75w85 to replace 75w90 and vice versa. Like 3057 vs 3157, these two lubricants have the same structure, function, and only a slight difference in performance.
So it is not too difficult to understand that both these products are interchangeable if the product you are using for some reason cannot be used or is not available. And of course, there will be some variation when we use each type of lubricant.
Do new and old oils work together?
It is not the oil but the additives in each product that are the leading cause of any type of oil reacting.
Therefore, you need to carefully refer to the ingredients and the recommendations from the manufacturer to avoid encountering this dilemma.
What does the letter W mean?
The letter W is the symbol for the word Winter to clearly show users the stable performance of these products in cold and snowy weather conditions.
Conclusion
Hopefully, through the knowledge that today’s article brings, you will know the difference and similarity of two quality lubricants, 75w85 and 75w90. From there, it will be easier and faster to choose a suitable solution for the vehicle.
