I own a 2000 Cherokee that's currently running fine. A friend recommended using Sea Foam in the gas and engine to clean it up. I'm curious if this product is effective or just a waste of money. The cost is about $12, which isn't much, but I'd like to know if it's worth it.

Hey there, Mary! Sea Foam is indeed a popular product used for cleaning engines and fuel systems. Many users have reported positive results, particularly in older vehicles like your 2000 Jeep Cherokee. Here's a breakdown of what Sea Foam can do, just for context:
  1. Cleaning Throttle Body and Carburetor: It's effective in cleaning the throttle body and carburetor. Users have successfully used Sea Foam with a toothbrush for thorough cleaning.
  2. Improving Old Gas Quality: Sea Foam can enhance the performance of old gas, making it run well.
  3. Engine Sludge Removal: It is known for its ability to clean out sludge from engines. Pouring it into the crankcase before an oil change can lead to significantly dirtier oil, indicating the removal of buildup.
  4. Fogging for Storage: Sea Foam is also used for fogging engines in storage, like chainsaws, keeping cylinders clean.
  5. Oil Additive for Noise Reduction: Some users have found that adding Sea Foam to the crankcase helps in reducing engine noise, like lifter ticking.
However, there are some considerations to keep in mind:
  • Not a Miracle Fix: It won't fix broken parts. If your engine has underlying mechanical issues, Sea Foam won't be a cure.
  • Potential Short-Term Effects on Worn Parts: If parts like rod bearings or seals are worn, Sea Foam might accelerate their wear by cleaning away debris that's cushioning them.
  • Usage Instructions: To add it to the crankcase, you pour it into the same place where you add motor oil.
  • Smoke Generation: Be aware that using Sea Foam, especially through the intake, can cause a significant amount of smoke. It's best not to do this in densely populated areas.
  • Not Always Necessary for Low-Mileage Vehicles: For newer or low-mileage vehicles without much carbon buildup, the effect might be minimal.
  • Post-Use Maintenance: After using Sea Foam, you might need to replace oil, air filters, and possibly the fuel filter, as it can dislodge a lot of debris.
In summary, I've personally found that Sea Foam can be a pretty useful product for maintaining and cleaning certain aspects of your engine and fuel system, especially in older vehicles. Just remember, it's not a substitute for mechanical repairs and should be used according to the instructions for the best results. Zack - Motor Verso Mechanics Team
