Coolant and antifreeze is a topic we are asked about on a regular basis, and often causes confusion; types, colours, service life etc. Perhaps the most frequent cause of confusion is what the difference between anti-freeze or coolant is. Basically, they’re the same product (although the term “coolant” could just be applied to plain water; see below!) To help clear some of the confusion up on the more technical details of antifreeze and coolants we enlisted the help of Martyn Mann – Technical Director, Millers Oils UK - who has provided the information below. Not all antifreeze / coolant is the same! Coolant can be plain water; water is a very effective coolant but would not protect against sub freezing temperatures or protect against corrosion inside the engine. The use of antifreeze protects against both problems. Antifreeze not only suppresses the freezing point of your engine coolant, but provides good corrosion protection and increases the boiling point during use. Most commercial antifreeze formulations include a glycol (to suppress the freezing point and raise the boiling point), corrosion inhibiting compounds and a coloured dye (commonly orange, green, red, or blue fluorescent) to aid in identification. A 1:1 dilution with water is usually used, resulting in a freezing point in the range of minus 37 °C to minus 42 °C, depending on the formulation. There are two basic types of coolant available today dependent on the corrosion inhibitors used: ·inorganic additive technology (IAT) ·organic additive technology (OAT) Inorganic Additive Technology This is the traditional coolant based on inorganic additives and is called inorganic additive technology (IAT). It is a tried and proven chemistry that provides a fast acting protective film. The additives deplete and the coolant needs to be drained and replenished every couple of years. This type can be used on all mixed metal engines with components including steel, cast iron, copper, brass, aluminium and solder without any detrimental effect. Organic Acid Technology The newer OAT coolants work differently than the older silicate based IAT coolants. Aluminium and ferrous metals form a surface-layer of corrosion in the presence of moisture, even with the little bit of moisture in the air. OAT coolants prevent this metal-oxide layer that protects the surface against this corrosion. Inherent with their design, the OAT coolants last longer than the older traditional IAT coolants. This category of antifreeze cannot be used in systems containing yellow metals. A couple of questions and answers. Why are coolants different colours? Coolants/antifreezes are coloured so you can visually see them; colour intensity can be an indication of over dilution. The different colours are non specific to the different types of antifreeze. The manufacturer can dye the product any colour they want. The colour is no guide to the actual type of antifreeze type and the label should be read before use. What is best for performance use? It is always best to use the engine manufacturer’s advice. If engine contains yellow metals [copper and brass as in older vehicles] then the long life products based on organic technology should not be used. As a general rule, most modern engines require the long life organic antifreezes. Is there any advantage to using concentrate over pre-mixed coolants? None other than the user may want to use the pre-mixed product due to ease of handling or cost and visa versa. Can concentrate and pre-mixed coolants be mixed? A simple answer is that you can, however do not mix IAT and OAT antifreeze together. So, there we go. Hopefully this information has been useful, if you have any further questions not covered here please ask and I will try to get the answer. With thanks to Martyn Mann and Millers Oils. Cheers Guy and the Opie Oils team.

Very few vehicles need a DOT5 fluid, so few that we don't sell one. It's mainly military vehicles that need it. If anyone has been recommending it on here, I'd guess they are getting confused with DOT5.1.
-
As the fluid heats up, it will move around, kind of like a convection current in a kettle etc. The heat comes from the brakes, but will affect the fluid in the whole system.

Brake fluid... Bit of a mystery topic! To help dispel some myths and for some good solid general info on the mysterious world of brake fluids I decided to contact Millers Oils up in West Yorkshire. Their Technical Director, Martyn Mann was on hand to give us some useful info… below is Martyn's article on brake fluids. There is a degree of confusion regarding the specification of brake fluid and this article sets out to clarify the situation. The Department of Transportation (DOT) classifies brake fluids to defined specifications. These specifications relate to their boiling points and chemical composition, both of which are important. All currently available brake fluids are covered by one of the following specifications; DOT3, DOT4, DOT5 and DOT5.1. The laws of thermo-dynamics dictate that the energy from motion is turned into heat through friction. A braking system only works efficiently if the fluid remains incompressible. If the brake fluid boils, it turns to gas, which is compressible and the braking system becomes “spongy” or in extreme cases fails completely. A brake system is not perfectly sealed and moisture can get into the system and be absorbed by the fluid. The effect is to reduce the boiling point of the fluid, which reduces the efficiency of the braking system, as described above. The DOT specifies two reference tests for brake fluids. * Dry boiling point - the boiling point of fresh fluid * Wet boiling point –the boiling point once the fluid has absorbed moisture (representing brake fluid after time spent in a real situation). There are two main types of brake fluids: * DOT 3, DOT 4, Super DOT4* and DOT 5.1 which are based on poly glycol compounds. * DOT 5, which are based on Silicone. Note the two types of fluid are not compatible and must not be mixed in a braking system. SILICONE BRAKE FLUID (DOT 5) Silicone based DOT 5 was originally introduced to give higher temperature performance over glycol DOT 4. Silicone fluid also has other advantages, it does not damage paintwork and it does not absorb water. However, silicone fluid is a poor lubricant and does not lubricate ABS pumps as well as PAG fluids. It is also more compressible than PAG fluids, which can result in a sluggish or spongy pedal. It therefore requires special design considerations in braking systems. Further, because it does not absorb water, any water remains as globules, which can pool in low spots in the system and cause corrosion. This water can vaporise when heated under heavy braking giving a disastrous effect on braking efficiency. DOT5 fluids are not recommended for motor sport applications. POLY GLYCOL BRAKE FLUIDS (DOT 3, 4 AND 5.1) Glycol based DOT 4 fluid is the current mainstream brake fluid, and you will see that the specification is considerably better than DOT 3 which it replaces. DOT 5.1 has higher specification still and is for fast road and occasional track day use. It has a similar spec to DOT4 for the boiling point (>260) but is a lot lower viscosity @-40C typically 900 centistokes (compared to 1500 - 1800 centistokes for DOT 4 and super DOT 4). Listed in the table below, are the minimum dry/wet boiling point specifications for each DOT level. BOILING POINT: DOT 3 - 205°C (dry) / 140°C (wet) DOT 4 - 230°C (dry) / 155°C (wet) DOT 5 (silicone) - 260°C (dry) / 185°C (wet) DOT 5.1 (PAG) - 260°C (dry) / 185°C (wet) Super Dot4 * - 300°C (dry) / 195°C (wet) (racing brake fluid) * Super DOT4: The main difference between DOT 4 and Super DOT 4 is the dry boiling point. Normal Dot4 is >260C whilst Super DOT 4 is more like >310C With thanks to Martyn Mann - Technical Director Millers Oils. Cheers Guy. Opie Oils
