mishimoto-mmra-lc-fullf-liquid-chill-full-strength-synthetic-engine-coolant-1

For those seeking efficient cooling for their Jeep's engine, Mishimoto has you covered with their Liquid Chill Full Strength Synthetic Engine Coolant. This product combines a non-toxic propylene glycol base with poly-organic additives (POAT) to provide year-round protection for various engine types.

The Mishimoto coolant protects against boil-over up to 265°F and freezes down to -26°F, ensuring a stable operating temperature. Additionally, it reduces engine wear and seals pinhole leaks as it passes through the cooling system.

A key feature is that it doesn't leave any residues or clogs in the radiator or thermostat, extending the life of these components. Available in either Full Strength or 50/50 Pre-Diluted options, this coolant is a reliable choice for all water-cooled engine applications.

peak-antifreeze-coolant-50-50-prediluted-all-vehicles-1-gal-3-78-l-1

I've been using Peak Antifreeze + Coolant in my daily life for quite some time now, and I have to say it's been a game-changer for me and my car. This stuff is specifically formulated to deliver superior protection against damaging scale and corrosion, and it works marvelously. It contains 10 times the scale-fighting inhibitors to ensure maximum cooling system performance, and I've definitely noticed the difference in my car's performance.

One feature of Peak Antifreeze that's stood out to me is its universal formula. It's compatible with any color or type of antifreeze/coolant, which means it doesn't matter whether you're using a specific brand or color – this stuff will work with it all. This has been incredibly helpful for me, as it's meant I can use Peak Antifreeze in conjunction with any other antifreeze I've used before without any issues.

Another great thing about this product is that it meets the performance requirements of ASTM D3306 and D4985, which is an added bonus for anyone who's looking for a high-quality, reliable antifreeze. And the phosphate-free and silicate-free formula is a major plus, as it means this product is better for the environment and helps to maintain the integrity of your engine.

One slight downside I've found to Peak Antifreeze is that it does contain a small amount of Denatonium Benzoate, which is a bittering agent added to deter potential consumption of the antifreeze. While this is a good thing in terms of safety, it does mean that it's less pleasant to handle, especially if you need to clean up any spills.

Overall, though, I highly recommend Peak Antifreeze + Coolant to anyone looking for a high-quality, reliable antifreeze that works well in a variety of cars and is good for the environment. It's definitely made a noticeable difference in my car, and I wouldn't hesitate to use it again in the future.

west-marine-50f-engine-water-system-antifreeze-gallon-for-boats-1

I recently had my hands on the West Marine -50F Engine & Water System Antifreeze, and let me tell you, it did a fantastic job protecting my boat during the cold winter months. As someone who lives in a mild but freezing winter region, I needed an antifreeze that could keep my potable water systems, sanitation systems, and all engines running smoothly without any issues.

One of the highlights of this antifreeze is its use of pure virgin propylene glycol. Not only does it provide quality and effectiveness, but it also reduces residual smells and tastes. Additionally, the product contains corrosion inhibitors that prevent damage to metal engine components and seals, making it an ideal choice for any boat.

The bright triple die pink color is a fantastic feature as well. It lets users know when antifreeze has traveled through water lines, sanitation system lines, or engine cooling systems. It even serves as an indicator when flushing systems in the spring. I found it incredibly helpful in knowing when to start preparing my boat for winter and when I could safely start using it again in the spring.

Now, while this antifreeze is fantastic, I did find one issue with the label. It claims to offer protection down to -50 degrees Fahrenheit, however, upon further investigation and reading the application instructions, I realized that this claim is misleading. The antifreeze is only good for temperatures down to 7-10 degrees Fahrenheit. While this works well for my region, it might not be the best choice for those living in colder areas.

In conclusion, the West Marine -50F Engine & Water System Antifreeze is an excellent product that provides top-notch protection for boats during colder months. Its use of pure virgin propylene glycol and inclusion of corrosion inhibitors make it stand out in a sea of potentially costly and damaging antifreeze options. Just be sure to note the temperature range that it can actually handle, and you'll be all set for a safe, effective, and winterized boat.
