You’re looking to switch up your engine oil, but you’re not sure which way to go. Do you go with the tried-and-true Rotella T4 or experiment with the newer Rotella T5?
Both oils are excellent choices for a variety of reasons. But there are a few key distinctions that might make one or the other a better fit for your needs. Now the question is, which is better to pick between Rotella T4 VS T5?
Undoubtedly, both of these oils are really great. But there are some facts that put one oil slightly ahead of the other. Based on various factors we would recommend Rotella T5 to you.
In order to clear your confusion, we will try to share the difference between these two oils through this article. This will help you choose the best oil for you.
Head to Head Comparison between Rotella T4 VS T5
In the world of motor oil, there are two major contenders in the industry: Rotella T4 and Rotella T5. Both are engineered with the same basic principles in mind, but there are some key differences between the two.
In order to make sure you’re choosing the right oil for your vehicle, we try to make a comparison between Rotella T4 VS T5. It will surely help you to pick the best one.
Viscosity
The viscosity of an engine oil is one of the most important factors that you need to consider when choosing an oil for your car. In terms of picking the best one between Rotella T4 VS T5, you also need to look out for this factor.
Rotella T4 has a viscosity of 5W-30, while Rotella T5 has a viscosity of 15W-40. This means that Rotella T4 is thinner and will flow more easily at low temperatures, making it a better choice for cars that are driven in cold weather. Rotella T5 is thicker and will provide better wear protection at high temperatures.
Performance
When it comes to performance, Rotella T4 and T5 are both excellent engine oils. However, Rotella T5 has the slight edge over Rotella T4 in terms of better wear protection and a higher temperature range. Rotella T5 also contains more additives that help to protect your engine against oxidation.
All things considered, Rotella T5 would be the better choice for an engine oil. However, if you’re looking for an oil with lower viscosity, Rotella T4 would be a good option.
Temperature Range
The Temperature Range is different for Rotella T4 and Rotella T5. Rotella T4 has a temperature range of -45°F to 250°F, while Rotella T5 has a temperature range of -30°F to 300°F. So if you’re looking for an engine oil that can handle the coldest temperatures, Rotella T4 is your best bet.
However, if you’re looking for an engine oil that can handle the hottest temperatures, Rotella T5 is the better choice. It also has better oxidation stability, meaning it’s less likely to break down over time. So if you’re looking for an engine oil that will provide superior wear protection, Rotella T5 is the better option.
Additives
The Rotella T4 and T5 are both semi-synthetic diesel engine oils, which means that they’re blended using both synthetic and conventional base oils. But when it comes to additives, there are some key differences between the two.
The Rotella T4 has more zinc-based anti-wear additives than the Rotella T5, which makes it a better choice for older, higher miles engines. The T5 offers more detergents and dispersants than the T4, which keep your engine clean and free of harmful deposits. So if you have a newer diesel engine with low miles on it, then the Rotella T5 is probably your best bet.
Oxidation
Oxidation is an important factor to consider when choosing an engine oil, as it’s concerned with the oil’s breakdown and its ability to form sludge, varnish and residues. So which one is better?
Rotella T4 has a higher oxidation resistance than T5 due to its higher viscosity index. T4, like most traditional motor oils, contains additives that help prevent oxidation. This makes it better in cold temperatures and increases its longevity.
On the other hand, Rotella T5 features a proprietary additive package which helps reduce oxidation and resists viscosity breakdown more effectively.
So in terms of oxidation resistance, T4 outshines more than T5. However, keep in mind that both products will still need changing based on the manufacturers recommendations or individual vehicle needs such as larger turbochargers
Wear Protection
When it comes to wear protection, both Rotella T4 and T5 are equally effective. The base oil in a conventional engine oil is mineral oil, while the base oils in synthetic engine oils are made from synthetic polymer molecules.
The molecular structures of these polymers are uniform and finely tuned, meaning that they can better resist heat degradation and the build-up of sludge and deposits. It means that both Rotella T4 and T5 provide excellent wear protection for moving engine parts, keeping them from rubbing against each other and causing excessive wear.
Cost
Let’s talk about the price. Rotella T4 and T5 both have similar pricing, so you won’t have to break the bank to use either of them. However, if you’re on a budget, then there are a few things to consider when deciding between the two.
Rotella T4 usually has a lower price per quart than Rotella T5, which might make it more appealing for those who want to save a few bucks. That being said, Rotella T5 is designed for heavier duty use and is capable of lasting longer before needing a change. So in the long run, it could be more cost-effective than Rotella T4.
It all depends on what your specific needs are and how often you plan on changing the oil in your vehicle. If you drive regularly and plan on changing your oil every 3–5 thousand miles, then you might want to go with an option like Rotella T5 that can last longer and save you money in the long run.
Rotella T4 VS T5- The Winner
So,we’re at the end and now it’s time to know which is better between Rotella T4 VS T5? If you take into account all the factors we looked at, the answer is a bit complicated. If you’re looking for an engine oil that offers superior wear protection, then Rotella T5 is the best choice.
On the other hand, if you’re looking for an engine oil that provides superior oxidation stability and can last longer between oil changes, then Rotella T4 is the better option.
The cost of both oils may also influence your decision. Rotella T4 is usually more affordable than Rotella T5 due to its high viscosity rating and longer intervals between oil changes.
However, if you need a motor oil that offers superior wear protection and temperature range performance, then you may be willing to spend a bit more on Rotella T5. Ultimately, it depends on what your specific needs are. Both oils will provide maximum performance when used correctly in their designed environment.
Final Thought
It can be surely said that both Rotella T4 and T5 engine oils are great products. However, if you are looking for the best engine oil for your needs, Rotella T5 would be the better option. But T4 is also a great oil to use as well. So the choice depends on you.
In this article, we made a comparison between Rotella T4 VS T5 and made a decision which is perfect to pick. Hopefully, this article will be helpful for all of you. Thank you all.
