Valvoline Def and Blue Def are two common diesel exhaust fluids (DEF) used to reduce emissions from diesel engines.
Both products are designed to meet the Environmental Protection Agency (EPA) requirements for reducing nitrogen oxide (NOx) emissions, but there are some differences between the two.
This blog will explore those differences to help you choose the right DEF for your vehicle.

Difference Between Valvoline def vs Blue def
The main difference among various brands of DEF is their level of purity in the fluid. To get the best result, it is essential to meet the standard of purity of this fluid.
Well, both Valvoline & Blue Def meet international & EPA standards. We discuss the best brands for your vehicle.
EPA Standards
Valvoline high-quality fluids meet EPA requirements. EPA declares the limit of impurities that should contain a DEF. Valvoline DEFs come with minimum EPA limits to ensure low impurities.
That’s the main difference between quality DEFs. Also, it is API, AdBlue & ISO 22241 approved. That means it meets all the international standards.
Also, Blue Def comes with minimum EPA limits to deliver pure products. It is also approved by API & ISO 22241. That means both Blue def & Valvoline are pure & certified products.
Urea
Good manufacturers maintain materials quality & standards to provide pure products.
That is contamination-free. Both Valvoline & blue def uses pharmaceutical-grade urea to improve purity. They don’t mix agricultural grade urea to reduce cost.
Performance
Valvoline is the best-performing fluid that comes with the highest level of purity. It also ensures the maximum level of NOX reduction to improve engine reduction.
The best part is it performs unbeatable in the SCR system to ensure zero NOx.
It provides a fill hose to ensure a smooth flow of fluid into the DEF tank for e perfect mixture with NOx.
Blue def also produces Nitrogen gas to reduce NOx in the SCR system. It decreases the NOx throwing level to improve engine performance. Also, it performs well in the SCR system to reduce NOx.
But it can’t guarantee to ensure zero NOx like Valvoline. Also, it gives a filling tube for safe attachment with the DEF tank.
But if the attachment is not appropriate, that creates a risk of causing the leak on the fill tube.
Price
The main difference between Valvoline def and blue def is its price. Blue def is an affordable choice for all-range vehicle owners. It comparatively offers some premium features than its minimum price range.
Well, this inexpensive oil can support up to 6000 miles with a 20-gallon DEF tank. So the fun part is one gallon can go up to 300 miles. That is a real money saver.
On the contrary, Valvoline is an expensive choice. But obviously, it performs better than blue def.
Well, Valvoline ensures zero NOx emissions level in a Selective Catalytic reduction (SCR) system.
Recommendation
After comparing both Valvoline def & blue def, it is confirmed that both are high-quality def.
Suppose you are looking for high performance, then Valvoline is the best choice.
But if you are looking for the best budget def with good performance, then blue def is a must for you.
But if you have a diesel fuel vehicle, you can’t skip def. According to the EPA, all cars are designed in a way that requires DEF. So for your car’s safety choosing high-quality def is a must.
Why brands matters
Well, if you put a low-quality brand fluid that can damage your engine performance. Let’s learn how brands can create a difference.
Impurity
EPA level indicates the impurity level of DEF. It has a standard limitation that high-quality brands meet & follow.
But unfortunately, poor brands add too much impurity. That fails to reduce NOx emissions in SCR. As a result, it will be a waste of money.
So don’t only jump for the price. Check the impurity level & compare it with EPA standard level. The lower the impurity that indicates, the higher performance like Valvoline or blue def.
Urea
Reliable & standard brands choose pharmaceutical-grade urea to improve purity levels.
At the same time, low-quality brands use agricultural-grade urea that is engulfed with impurities.
Standards
When you are going to buy a DEF, it is highly important to check whether the product meets all the EPA standards, such as ISO 22241.
Without meeting this standard, any cheap product can damage your vehicle.
If you love your vehicle, don’t play with your luxurious car. A wrong brand’s fluid can damage your favorite car.
So, choose a high-quality brand like Valvoline or blue def to derive the best performance.
Final Word
Choosing between Valvoline Def and Blue Def depends on your specific needs and preferences.
While both products are effective in reducing NOx emissions, they differ in terms of their composition and performance in extreme temperatures.
Valvoline Def better option for colder climates, while Blue Def may be more suitable for hotter temperatures.
It is important to follow the manufacturer’s recommendations and use a DEF that is compatible with your vehicle to ensure optimal performance and emission reduction.
