What is Active Fuel Management Delete (AFM delete) and what are the benefits of doing it on your car engine
Active Fuel Management Delete (AFM delete) is an option to turn off some of the features on your car engine. It may be beneficial if you want a more fuel-efficient vehicle but there are trade-offs when turning these things off so do plenty of research first!
Active Fuel Management (AFM) is a technology used in some General Motors engines that allows them to operate on only four cylinders during light-load driving conditions, such as highway cruising. This improves fuel economy by up to 9 percent.
When AFM is active, the engine computer deactivates two pairs of cylinders, effectively turning the engine into a four-cylinder. The deactivated cylinders are reactivated when more power is needed, such as when accelerating or climbing a hill.
The main benefit of AFM delete is improved performance. With AFM disabled, the engine can stay in eight-cylinder mode for longer, providing more power when you need it. This can be especially beneficial if you often tow or haul heavy loads.
AFM delete kits are available from aftermarket suppliers and can be installed by a qualified mechanic. Doing so will void your vehicle’s warranty, so it’s important to weigh the pros and cons before making a decision.
Problems that can occur after AFM delete and how to solve them
One of the most common problems that can occur after an Active Fuel Management delete is engine knock. Engine knock is a knocking or pinging noise that comes from the engine because of uncontrolled combustion. This can be caused by a number of factors, but one of the most common is using lower-octane fuel than what is recommended for your vehicle. If you are experiencing engine knock, the first thing you should do is try using a higher-octane fuel. If that doesn’t solve the problem, there are a number of other potential solutions, including changing the spark plugs, adjusting the timing, and adding an octane booster to the fuel.
Another problem that can occur after an Active Fuel Management delete is increased exhaust temperatures. This is because the Active Fuel Management system regulates the amount of fuel that is burned in the engine, and when it is deleted, there is no longer any regulation. This can lead to increased exhaust temperatures, which can damage the exhaust system and potentially cause other problems. If you are experiencing increased exhaust temperatures, you should try adding an exhaust gas temperature (EGT) gauge to your vehicle so that you can monitor the temperatures and make sure they don’t get too high.
If you have delete your Active Fuel Management system, it is important to be aware of these potential problems and be prepared to deal with them if they occur. By taking some simple precautions and being ready to take action if a problem does occur, you can help keep your vehicle running smoothly and avoid any serious issues.
Active Fuel Management delete kits are available from a number of different manufacturers, and they vary in terms of price and quality. Before you buy a kit, it is important to do some research to make sure you are getting a good quality product that will work well with your vehicle. There are a number of online forums where you can read about other people’s experiences with Active Fuel Management deletes and get advice on which kits are the best. Taking the time to do your research before you buy can save you a lot of time and money in the long run.
When you are ready to install the Active Fuel Management delete kit, it is important to follow the instructions carefully. If you are not comfortable doing the installation yourself, there are a number of companies that offer installation services. Once the kit is installed, it is important to take your vehicle for a test drive to make sure everything is working properly.

DOD/AFM Delete: What Happens If You Put Oil In It?
If you’ve ever wondered what would happen if you put oil in your Active Fuel Management delete, wonder no more! We did the experiment so you don’t have to. Check out the results below.
The Active Fuel Management (AFM) system is designed to improve fuel economy by deactivating cylinders when they’re not needed. This reduces engine displacement and overall weight, resulting in better fuel efficiency. However, some enthusiasts believe that the AFM system can cause performance issues, so they opt to remove it entirely.
If you choose to do an AFM delete, you’ll need to use a different oil than what’s typically recommended for vehicles with this system. A regular motor oil won’t be able to properly lubricate the deactivated cylinders, so you’ll need to use a special oil that’s designed for AFM deletes.
We tried using regular motor oil in an AFM delete and the results were not good. The engine didn’t run smoothly and eventually seized up completely. We had to replace the entire engine as a result.
So, if you’re considering an AFM delete, just be aware that you’ll need to use the proper oil or you could end up causing serious damage to your engine.
