“Which Brand of Coolant Is the Best?” is a common question that comes up when people are looking to buy new coolants for their vehicles. There are many different brands from which to choose, and some have the reputation of being better than others. These days, there are countless online articles and reviews that will help you choose the appropriate brand for your vehicle’s needs. In this article, I will discuss how important it is for every driver to purchase only the best coolant for their vehicle.
The best engine coolant brand depends on the type of vehicle. There are coolants that are designed to work well in gasoline engines, diesel engines, and even hybrid engines. Depending on the type of vehicle, you will have a choice between an inorganic and organic engine coolant.
Which Brand of Coolant Is the Best?
Coolant for Gasoline Engines
A popular engine coolant brand for gasoline engines is “Genuine BMW Longlife-04”. This particular coolant is a mixture of ethylene glycol and propylene glycol. This coolant does not contain any silicates and it contains special corrosion inhibitors designed for use in engines that are exclusively operated on regular gasoline.
Coolant for Diesel Engines
For diesel engines, a famous coolant brand is “Mercedes Benz Long Life Coolant”. This particular brand is a mixture of ethylene glycol and urea. It contains special corrosion inhibitors such as borate that are designed for use in diesel engines. It also contains a pH-buffering agent to ensure the coolant is at the proper level of alkalinity.
When you are on the road, your car’s coolant is working hard to keep your engine’s temperature stable.
Inorganic Coolant vs Organic Coolant
Inorganic coolants are typically more resistant to corrosion than organic types. They also offer better protection for aluminum parts. This includes antifreeze corrosion protection as well as aluminum cylinder head protection against galling and end-sealing of the water jacket passageways.
Organic coolant is typically more environmentally friendly and will not contain lead, which is a heavy metal that can cause health problems. Organic coolants are naturally biodegradable and break down into harmless compounds when they are exposed to the air. They also do not contain any petroleum distillates as inorganic coolants do.
The easiest way to determine if an engine coolant is organic or inorganic is by looking at the ingredients on the bottom of the bottle.
For instance, a coolant known as “Mercon V” is an inorganic engine coolant that protects against corrosion and contains no borates. This particular brand also protects against chloride pitting and does not require the use of pH-adjusting agents
Coolant known as “Maxlife Antifreeze/Coolant” is an organic engine coolant that protects against corrosion and contains no silicate.
The main ingredient in this particular brand of coolant is ethylene glycol. Ethylene glycol is also an ingredient in many antifreeze brands.
Antifreeze is what prevents the coolant from freezing at low temperatures, and it also prevents water from being readily absorbed by the engine.
