My Buying Guide on ‘Best BMW Diesel Exhaust Fluid’
As a BMW owner, I know how important it is to use the right diesel exhaust fluid (DEF) in your car. DEF is a liquid that helps to reduce harmful emissions from diesel engines, and it’s essential for keeping your car running smoothly and efficiently.
But with so many different DEF brands and products on the market, it can be hard to know which one is the best for your BMW. That’s why I’ve put together this buying guide to help you choose the right DEF for your car.
What is DEF?
DEF, or diesel exhaust fluid, is a type of urea-based solution that is used to reduce harmful emissions from diesel engines. DEF is injected into the exhaust stream, where it reacts with the NOx (nitrogen oxides) produced by the engine to form harmless nitrogen and water vapor.
Why do I need DEF?
All diesel engines manufactured after 2010 are required to use DEF in order to comply with EPA emissions regulations. If you don’t use DEF in your BMW, your car will not pass emissions testing and you could be fined.
What are the different types of DEF?
There are a few different types of DEF on the market, but they all contain the same active ingredient: urea. The main difference between different DEF products is the concentration of urea. Most DEF products are sold in a 32.5% urea solution, but some products are available in a 16.25% urea solution.
How much DEF do I need?
The amount of DEF you need to use will vary depending on your car’s engine size and how much you drive. However, as a general rule of thumb, you should expect to use about one gallon of DEF for every 5,000 miles driven.
Where can I buy DEF?
DEF is available at most auto parts stores, gas stations, and truck stops. You can also order DEF online from a variety of retailers.
How do I use DEF?
DEF is added to the DEF tank, which is usually located near the fuel tank. The DEF tank is typically labeled with the DEF symbol, which is a blue circle with a white “DEF” inside.
To add DEF to your car, simply open the DEF tank cap and pour the DEF into the tank until it reaches the full line. Be sure to close the DEF tank cap tightly after you’re finished.
What happens if I run out of DEF?
If you run out of DEF, your car’s engine will go into a “limp mode” where it will only run at a reduced power output. This is to prevent your car from emitting too much NOx. You will need to add DEF to your car as soon as possible to get it out of limp mode.
How can I keep my DEF tank full?
There are a few things you can do to keep your DEF tank full:
- Check your DEF tank regularly and add DEF as needed.
- Fill up your DEF tank at the same time you fill up your gas tank.
- Sign up for a DEF delivery service so that you never have to worry about running out of DEF.
Conclusion
DEF is an essential fluid for all diesel engines manufactured after 2010. By using the right DEF, you can help to keep your car running smoothly and efficiently, and you can also protect the environment by reducing harmful emissions.
Here are a few tips for choosing the best DEF for your BMW:
- Choose a DEF product that is made with high-quality ingredients.
- Look for a DEF product that is certified by the American Petroleum Institute (API).
- Choose a DEF product that is compatible with your car’s engine.
By following these tips, you can be sure that you’re choosing the best DEF for your BMW.
