Description
CEM’s Marine Diesel Stabilizer is a premium diesel fuel stabilizer that is specifically designed and tested for marine applications. This includes boats running on standard diesel, biodiesel, or modern ethanol blends.
Its concentrated formula and precise dosage make it easy to use. All you need to do is simply add Quickstor when you fill up or refill your tank, and let it mix through the fuel system. This ensures your stored fuel stays fresh and will prevent diesel from breaking down over time.
For boat owners, maintaining fuel condition is critical. Poor fuel quality, water contamination, and algae growth can quickly lead to blocked injectors. Over time, this can reduce engine performance and lead to costly repairs. This product actively works to prevent these common problems before they start.
As most marine users know, water in diesel engines can lead to serious engine issues. CEM’s stabilizer helps control moisture, reduce corrosion, and stop biological growth from forming inside the tank. Aside from preventing contamination, it also cleans existing systems by breaking down sludge, gum, and carbon deposits already present.
The result is a cleaner-running engine with improved reliability. You also get a more efficient vehicle or boat that performs consistently whether on the road or at sea.
Used regularly, this stabilizer supports long-term protection of your engine, fuel injectors, and overall fuel system. This makes it an essential part of your marine maintenance routine.

1991 Fairways 36 that had a huge fuel bug issue in both tanks. After getting a price for both tanks to be flushed, to get rid of the fuel bug and picking myself off the floor, I decided to add FTC to full tanks of fuel.
The FTC broke down the bug, and separated it from the fuel. This made it very easy to remove the bug contamination, by draining the bottom of the Racor primary filter approx. every 5 hours of running. By the second tank of fuel (with FTC) added there was very little to be drained and now it’s completely clean.
CAT 3116 I had a problem with my starboard engine(cat 3116)blowing smoke. I ran the FTC Decarbonizer through three tanks of fuel and it seems to have fixed the problem. Would recommend it to anyone great product.
