Rotella T4 VS T6- Head to Head Comparison
Both oils are designed to provide superior engine protection and performance. However, there are some key differences between the two products. Here are some of the most notable differences between Rotella T4 VS T6.
When looking at the base oil, both Rotella T4 and T6 have high-quality base oils. However, the Rotella T4 has a higher quality base oil that is purer. The Rotella T6 has a base oil that is more synthetic.
The synthetic base oil in the Rotella T6 can be more harmful to the environment and is not as biodegradable as the pure base oil in the Rotella T4. The Rotella T4 is also GMO-free, while the Rotella T6 has GMO ingredients.
The Rotella T4 also contains more antioxidants than the Rotella T6. These antioxidants protect the oil from becoming rancid and help to keep it fresh.
Overall, the Rotella T4 has a higher quality base oil that is more environmentally friendly and healthier for your skin.
If you look at the viscosity of these oils, then you can’t find many differences between them. Rotella T4 has a viscosity of 40 cSt at 100°C, while Rotella T6 has a viscosity of 50 cSt at 100°C. However, Rotella T4 does have a higher shear stability than Rotella T6, meaning it is less likely to thin out under mechanical stress.
In terms of shear stability, Rotella T4 falls short when compared to Rotella T6. Shear stability is key in order to preventing the oil from breaking down and becoming ineffective.
Rotella T6 additives help to improve shear stability and keep the oil intact even under high pressure and extreme temperatures. This ultimately means that your car’s engine will run smoother and be less likely to experience any type of failure.
Let’s move on to the additives in the oil. Both Rotella T4 and T6 contain lots of additives and detergents to help clean and lubricate the engine, as well as anti-foam and anti-corrosion agents.
However, the T6 has an additional component that improves its oxidation stability, which helps it stay in good condition for a longer period of time.
On top of that, it’s also worth mentioning that both products are low ash formulas and have low levels of phosphorus and sulfur. The T4 contains 15 ppm of phosphorus while the T6 has only 11 ppm.
And both are ENHANCED with shear stabilization agents, which helps them resist shearing and breaking down at higher temperatures – something that’s particularly important if you’re driving in extreme conditions like off-roading or towing a heavy load.
Now, if you’re trying to decide between Rotella T4 VS T6, one of the things you’ll need to consider is compatibility. Rotella T4 is specifically designed for use in turbo-charged diesel engines, which means it likely won’t be compatible with gasoline engines.
It is also not suitable for use in vehicles with catalytic converters due to its high sulfur content. On the other hand, Rotella T6 is a synthetic oil that can be used in both gasoline and diesel engines, making it a great choice for those who want one oil that can do it all. It also has lower sulfur content than the T4, so it’s more environmentally friendly.
So, let’s talk about pricing. The cost of the Rotella T4 can vary tremendously depending on where you buy it. It can range in price from as low as $15 to as high as $40 for a gallon of oil. The Rotella T6 is usually a bit more expensive and can range in price from about $20 to $60 for a gallon of oil.
Ultimately, when it comes to price, there isn’t a huge difference between the two oils. So, if you’re looking for an affordable option that still provides good performance, then the Rotella T4 might be your best bet. On the other hand, if money is not an issue and you want top-of-the-line performance, then the Rotella T6 is definitely worth considering.
Rotella T4 VS T6- The Winner
When it comes to Rotella T4 and T6, it really depends on what kind of engine you have and what your specific needs are. Both oils offer impressive protection and performance, but the best option is the Rotella T6. It offers superior protection against sludge, excellent fuel economy, and increased shear stability. It’s also compatible with a wider range of engines and lubricants than the Rotella T4.
If you have an older engine or a diesel engine that requires a lower viscosity oil, then Rotella T4 is still a great choice as well. It’s more affordable than the T6, and its thinner viscosity provides great protection for older engines that require less oil pressure.
So, in the end, when comparing Rotella T4 VS T6- The Winner is Rotella T6 for most people due to its superior protection and fuel economy benefits.
Frequently Asked Questions
Why is Rotella T6 so good?
Rotella T6 is a high-performance synthetic oil that is specifically designed to meet the needs of modern diesel engines.
