That knocking sound? Yeah, we know how frustrating it is. We’ve dealt with it too, and trust me, it’s not something you want to ignore. If you leave it alone, it can turn into serious engine damage. But don’t worry—we’ve learned exactly what works, and we’re here to help you fix it the right way.
So, what’s the deal with engine knock additives? Well, they’re special chemicals that help stop that annoying knock by boosting octane, improving fuel combustion, and cleaning out carbon buildup. The trick is to pick a good one, use it the right way, and stay consistent. Oh, and using better fuel and keeping the engine clean? That helps too.
But here’s the thing—just dumping in an additive won’t magically fix everything. There are a few key things you need to know to get the best results. Keep reading, and we’ll walk you through it all step by step!
Choose the Right Additive
Alright, let’s talk about picking the right additive—because trust me, not all of them work the same way. I’ve made the mistake of grabbing the first bottle I saw, and yeah… that didn’t go well. Some additives are great at boosting octane, while others are made to clean out nasty carbon buildup.
If your knock is from cheap gas, you need an octane booster. But if your engine has gunk built up inside, a detergent-based additive is what you want. Brands like Lucas, Sea Foam, and Royal Purple? Solid choices. Just read the label before you buy—seriously, it’ll save you time and money.
Use It Regularly
Let me tell you something I learned the hard way—one bottle of additive isn’t gonna fix everything overnight. I used to think I could just dump it in once and boom, problem solved. Yeah… that’s not how it works.
If your engine has been knocking for a while, it probably has some gunk built up inside, or maybe it’s just not getting the right fuel. Either way, one treatment might help a little, but if you want that smooth, quiet ride, you’ve gotta use it regularly.
Think of it like brushing your teeth. You don’t just do it once and expect perfect teeth forever, right? Same thing with your engine. I usually add a bottle every few tanks, especially if I’m using cheaper gas. It helps keep everything clean, stops knocking before it even starts, and just makes the engine run better. And honestly? It’s way cheaper than paying for engine repairs later.
I noticed a big difference once I started doing this. My engine ran smoother, it felt more responsive, and that annoying knock? Gone. So, if you want your car to stay happy, don’t just use an additive once—make it a habit!
Go for Higher-Octane Fuel
I used to think gas was just gas. As long as the tank was full, I was good to go. But then my engine started knocking, and I had no idea why. Turns out, the fuel I was using wasn’t cutting it. Some cars need higher-octane fuel, and if you don’t give it to them, they’ll start complaining—loudly.
I learned this the hard way when I tried saving a few bucks by using regular gas instead of premium. Yeah… a big mistake. My car felt sluggish, and that knocking sound was driving me crazy. Higher-octane fuel burns better and keeps everything running smoother.
It helps prevent knocking, especially in high-performance engines. And yeah, it costs a little more, but trust me, it’s worth it. When I switched back to premium, my car ran like a dream—no knocking, better acceleration, and just overall smoother driving. It felt like my engine was thanking me.
So if your car recommends premium, don’t ignore it. And even if it doesn’t, throwing in a tank of higher-octane fuel now and then can help, especially if you’re dealing with engine knock. Give it a shot—you’ll probably feel the difference right away!
Keep Your Engine Clean
Let me tell you—keeping your engine clean is way more important than I thought. I used to think if I kept adding fuel and changing the oil, everything would be fine. But then I started hearing that annoying knocking sound again, and I realized I was missing something big.
Over time, carbon buildup can sneak into your engine. It coats the pistons, valves, and spark plugs, messing up how your engine burns fuel. And guess what? That leads to knocking. Keeping everything clean isn’t hard, but it does take a little extra attention. First off, I started using a good fuel additive every few tanks.
It helps clean out carbon before it becomes a big problem. I also noticed that using higher-quality fuel with better detergents helped a lot. And I made sure to stay on top of regular maintenance. Changing the oil on time, cleaning the spark plugs, and getting my intake valves cleaned now and then really made a difference.
Ever since I started paying attention to the cleanliness of my engine, my car runs way smoother. The knocking stopped, and my car just felt better overall. Trust me—keeping your engine clean is like giving it a spa day.
Check Your Spark Plugs
Okay, let me be real—I used to completely ignore my spark plugs. I thought, “They’re just little parts, they’re fine.” But when that knocking sound started up again, I learned the hard way that I couldn’t just brush it off.
Spark plugs are super important. They’re the ones that light up the fuel in your engine. If they’re worn out or the wrong ones, they can mess up the timing of that spark, and you guessed it—knock, knock, knock.
Now, I make it a habit to check my spark plugs regularly. If they’re covered in dirt or carbon, that’s a sign they need cleaning or replacing. And here’s the thing—don’t just grab any spark plug from the store.
It’s so important to get the right one for your car. I didn’t realize that the heat range of the plug mattered, but it does! Using the wrong one can mess with your engine’s timing and cause knocking.
Once I switched out my old, worn spark plugs for the right ones, the difference was huge. My engine ran way smoother, the knocking stopped, and I felt a lot less worried every time I started the car. So trust me—don’t skip this step. Your spark plugs may be small, but they’re mighty!

Replacing It Isn’t That Hard
At first, I thought replacing spark plugs was something only a pro could do. I kept thinking it was too complicated for me, but honestly, once I gave it a try, I was surprised at how simple it was. If you’ve got a few basic tools, like a socket wrench and a spark plug socket, you can handle it.
So, the first thing I did was pop open the hood and find the spark plugs. Now, depending on your car, they might be easy to reach, or they might be a bit tricky, but once you locate them, it’s just a matter of unscrewing the old ones and swapping them out.
It’s pretty straightforward—just make sure to screw in the new ones carefully. Don’t want to mess that up, right? Once they’re in, tighten them, reconnect the wires, and you’re good to go.
And let me tell you, after I replaced those spark plugs, my car ran like a dream. The knocking was gone, and the car felt smoother, more responsive like it had a little extra pep in its step. Plus, I didn’t have to pay a mechanic to do it. So yeah, if you’ve been putting it off, don’t!

By picking the right additives, using them regularly, and making sure your engine stays clean, you can stop the knock before it gets worse. And don’t forget about the fuel and spark plugs—those little things do matter!
Once I started doing all this, my engine ran way smoother. The knocking went away, and my car just felt better overall. Sure, it took a little time and effort, but it was worth it.
