## Description

Gold Eagle ISO-HEET Premium Fuel-Line Antifreeze, Water Remover & Injector Cleaner is the premium gas-line antifreeze that absorbs up to 5 times the water of regular gas dryers. It is designed for year round use in all 2 and 4 cycle gas and diesel engines. ISO-HEET prevents rust and corrosion by getting the water out. This anti-freeze can be used with every fill up in below freezing temperatures or whenever you want to absorb water from gas or diesel fuel. This product comes in an easy pour 12 ounce bottle. Usage Directions: Twist off cap. Puncture seal. Pour ENTIRE contents into tank before or after filling with fuel. Bottle treats 20 gallons of fuel. Use with every fill-up in winter, and at least every 5,000 miles in summer to clean injectors. Removes water and condensation in warm, wet weather.

Review: Can’t Go Wrong - With today’s fuels containing a certain percentage of ethanol which can attract moisture, this product can absorb fuel tank water to keep your gas tank clean. I use it about four times a year & not just during the winter months. Plus it had a fuel injector cleaner as well.
Review: A Must-Have for Improved Engine Performance and Gas Mileage! - I recently tried **Iso-HEET Water Remover and Premium Fuel Line Antifreeze** and I’m very impressed with the results! I added it to my gas tank as directed, and I immediately noticed a smoother engine performance. My engine starts up more easily, even in cold weather, and it runs much more efficiently overall. I especially love how it helps to remove water from the fuel line, preventing any potential issues with fuel system freezing or corrosion. I’ve also noticed an improvement in my gas mileage. It feels like I’m getting more miles per gallon, which is a great bonus. The **Injector Cleaner** aspect is another huge plus—my car runs cleaner and more efficiently after using this product. At 12 fl. oz., the bottle is the perfect size for multiple uses and gives great value for the price. I highly recommend this product to anyone looking to improve their vehicle’s performance and extend its longevity. Definitely a great addition to my car care routine!

## Questions & Answers

**Q: how do i use it ? is it safe for any car ?**
A: I use it in combination with Marvel Mystery oil to make an fuel system cleaner. 5 parts MM to 1 part Heet. Works well in 3 cars I own - 2 Japanese and 1 German made.

**Q: Red bottle versus yellow bottle?**
A: I hope 5 years later David was able to find a new job. You can use this in any gasoline or diesel engine. The difference is the ISO (red bottle) contains isopropyl alcohol. The yellow bottle contains methanol. Isopropyl alcohol evaporates faster therefore removing the water faster. Methanol is better at lowering the water's freezing point. They both do both but just different ways.

**Q: Can I use these in my Yamaha outboard?**
A: Yes, any motor,engine that runs on gasoline, I used it on a snow blower

**Q: Isopropyl vs methanol Heet for removing water, one combine the water so it can be burned out, the other does not. Anybody know which one?**
A: At one point isopropyl was the only one recomended for fuel injected and other engines. I think it has less acidity than ethanol and methanol. It is the only one I keep in stock because it's safe and effective in all engines. I don't have to worry about someone using the wrong one.

### ⭐⭐⭐⭐⭐ Oh no. There's water in my fuel tank. I can smell it!!
*by K***L on May 13, 2026*

Be careful where you buy your gas. Especially if it has rained recently. Those underground tanks at the gas station build up condensation that drips right into the fuel. This is a good product to remove the water from the gas tank on your car or truck. It's a certain smell. You can recognize that smell when you are filling up your tank. When you smell it, get you some of this product before you run all that water through the fuel system in your car. It's a great product.
