This particular antifreeze formula contains no phosphates, making it less toxic for the environment. When it comes to performance, Volvo guarantees a total of 150,000 miles of regular usage or 300,000 miles of heavy-duty usage. The nitrites inside make this antifreeze friendly towards both diesel and gasoline engines.

Most commercial antifreeze formulations include corrosion inhibiting compounds, and a colored dye (commonly a fluorescent green, red, orange, yellow, or blue) to aid in identification. [19] A 1:1 dilution with water is usually used, resulting in a freezing point of about −34°F (−37°C), depending on the formulation. In warmer or colder areas, weaker or stronger dilutions are used, respectively, but a range of 40%/60% to 60%/40% is frequently specified to ensure corrosion protection, and 70%/30% for maximum freeze prevention down to −84°F (−64°C). [20] Maintenance [ edit ] There are two main types of antifreeze solutions. The first being made from ethylene glycol. The second type is made from propylene glycol. What is the difference, you ask? Well, ethylene glycol is WAY more toxic than its cousin propylene glycol. Ethylene glycol antifreeze If you want to make sure that the coolant you are using is compatible with your car’s engine, all you have to do is know if it’s a diesel or a gas one. Diesel is known for being “less clean,” and engines running on it tend to suffer the wear-out faster. The same rules apply for octane boosters or other engine supplements. While propylene glycol is known to be less toxic and slightly less potent that ethylene glycol, mixing the two together will not bring any harm to the engine or the cooling system of your vehicle. Do not expect that one type of alcohol will enhance the features of the other. They will function well when mixed.The standard color of HOAT antifreeze solutions may vary, but most commonly, you will find either yellow or bright orange. The mileage of HOAT solutions is similar to that of OAT, summing up at 150,000 miles or 5 years, depending on how you use your vehicle.

It is an OEM (Original Equipment Manufacturer) designed to service Lexus, Toyota, and Scion vehicle models made from 2004 onwards. The coolant comes in pure form in a 1-gallon container. Use it accordingly to work fine, especially for the plumbing system of your RV and marine vehicle. It can fit for use with cottages, boats, swimming pools, trailers, RVs, snowmobiles, among others, for more than once easily. This marine antifreeze solution is versatile, and you can use it a bit longer, making it worth buying it.Starbrite® -50°F (-46°C) Non-Toxic Antifreeze will provide burst protection to -50°F (-46°C) and freeze protection within a range of +12°F to +16°F (-11°C to -9°C). When testing with a refractometer or hydrometer designed for use with propylene glycol, freeze point readings on the PG scale will range from +12°F to +16°F. Note: The burst point of PVC pipes used in most drinking water systems is about -10°F (-23°C). When winterizing water systems in regions where temperatures can fall below -10°F (-23°C), we recommend using Starbrite® -100°F (-73°C) Non-Toxic Antifreeze. Propylene glycol – Found in less potent antifreeze fluids. However, propylene glycol is the least toxic among these ingredients, both for humans and the environment.

Keep in mind that ethylene glycol is much more poisonous and bad for the environment and that if you pour the less toxic propylene glycol in, it will not decrease the overall toxicity of the solution. All in all, this kind of combination is absolutely safe for your engine. 3. Is used up antifreeze still toxic? Firstly, we want to stress out that you can not put any kind of coolant/antifreeze solution into your car. It might seem like a logical choice, but if you just go with “whatever” option, you risk engine misfires and potential damages. The strong suit of IAT antifreeze is its ability to prevent corrosion, thanks to phosphates and a mix of ethylene glycol. On the other hand, inorganic liquids generally leave a harmful effect on rubber and plastic parts, like tubes, pipes and other plastic containers. Additionally, IAT is known to be not so environmentally friendly, and some states even banned the use of IATs, and are insisting on alternative antifreeze solutions out there.Although poisonous, ethylene glycol has a sweet taste and every year thousands of people, many of them children, and countless pets and wild animals, are poisoned by accidentally drinking antifreeze. Propylene glycol, on the other hand, is safe to consume, and is used as an additive in some foods to keep them moist. It is already used as an antifreeze in some industries such as food production, but its viscous, syrup-like consistency makes it unsuitable for widespread use. You may know that antifreeze comes in a variety of colours, from red and blue to green and orange, created by adding dye. Why? Mainly for historical reasons – the different colours reflected either where the product was made, the brand that made it, or the type of corrosion-preventing chemical it contained. The resulting solution is not only non-toxic, but may actually be more effective as antifreeze, with nearly double the heat transfer capacity of ethylene glycol-based formulations. ‘The thermal conductivity of these metallic [nanoparticles] is much higher than that of the base fluid, so if you put them in you increase the overall heat transfer,’ Clancy explains. Now, the number of degrees the freezing and boiling point will move from the standard 32° F and 212° F depends on the type of antifreeze, and on the amount of antifreeze in the mixture. We will, of course, touch upon that topic in the sections to follow. What Are Antifreeze Types? Sanco Industries made sure their product is what you look for in a food-grade propylene glycol multi-purpose antifreeze solution. This crystal clear, non-toxic and zero alcohol antifreeze product comes in a 1-gallon formulation with the highest purity and USP-certified ingredients. I like what it can do for many things, such as a humidifier, humidor, and marine RV antifreeze solution. The multi-purpose solution is also used as a de-icing fluid for aircraft to lower the water’s freezing point.
