ExxonMobil recommends Mobil Brake Fluid DOT 3 to be used in functions utilizing disc, drum, and skid brake programs on automobiles that require DOT Stage 3 efficiency. ExxonMobil use suggestions embody:

Use solely in your concentrated kind in pre-sealed or well-sealed

container All the time seal container instantly after use as liquid absorbs moisture from the environment pretty shortly; this may considerably cut back the service life.

By no means reuse drained brake fluid.

Brake fluid can have an effect on automobile paint, so take away spills instantly with out rubbing.

Brake fluid needs to be drained from the automobile each two years or 40,000 km (24,000 miles) and refilled.

See Proprietor’s & Operator’s Guide for particulars.


You’ve in all probability puzzled concerning the varied substances in your storage, particularly the lifetime of brake fluid. How secure is it to make use of a can or bottle of liquid that has been sitting within the storage or basement? You’re proper to consider this, because it’s not simply brake fluid, however numerous different automotive fluids and merchandise which have a particular shelf life as soon as opened (and even sealed). Understanding the distinction between what is appropriate to place in your automobile and what needs to be thrown away could make a giant distinction in how your automobile performs on the highway.


The shelf lifetime of brake fluid is straight associated to the quantity of moisture it’s uncovered to after opening the bottle. Brake fluid is hygroscopic, which signifies that it attracts and absorbs water from the encircling environment. The extra water it absorbs, the much less efficient it turns into when it will get into your automobile’s braking system. With water within the combine, the boiling level of brake fluid might be lowered significantly, which, given the stress it’s underneath throughout braking, interprets to much less efficient stopping energy and a spongy brake pedal.


When a bottle of brake fluid leaves the manufacturing unit, it’s sealed in order that it doesn’t are available in contact with outdoors air which might additionally comprise moisture. Most brake fluid producers declare {that a} sealed bottle doesn’t have a set expiration date. In a way, the liquid doesn’t break down over time and presents the identical degree of efficiency even after years on the shelf.

An open bottle is a distinct story. Even if you happen to’ve solely poured a little bit out of the bottle, you’ve launched moisture into the equation and begun the chemical means of absorbing that liquid from the air. Most producers suggest that any opened bottle of DOT brake fluid be used inside 12 months or thrown away. Please observe {that a} full yr is the outer restrict of what can be acceptable. A interval of three months is extra prone to supply a greater secure restrict by way of preserving the boiling level close to its unique degree.


Engine oil follows a distinct sample in comparison with the lifetime of brake fluid. Though moisture just isn’t actually an issue for the oil, the shelf lifetime of the components packed contained in the bottle has a particular influence on how lengthy it may be saved earlier than being thrown away.

In a secure setting, the place the temperature doesn’t fluctuate dramatically or attain extremes of scorching or chilly, you may get about 5 years out of a bottle of motor oil. Test the expiration date, as extra producers have began including this to every container. Energy steering fluid is an analogous story. Unopened, three to 5 years underneath regular temperatures is a secure window to be used.

Continuously requested questions

What’s it and what’s it for?

Brake fluid, also called hydraulic fluid, is a vital a part of your brake system. It’s used to transform the pressure into stress when urgent the brake pedal. It’s delivered by way of your automobile’s brake traces and works at extraordinarily excessive temperatures and pressures to convey your automobile to a secure cease.

What kinds of brake fluid can be found?

There are 2 most important kinds of brake fluid in the marketplace:

Glycol-based brake fluids: DOT 3, DOT 4, DOT 5.1

— or —

Silicone-based brake fluids: DOT 5

Brake fluid is assessed by the Division of of Transportation (DOT) utilizing a quantity between 1 and 5.1. This DOT quantity signifies the boiling level of the fluid. The upper the DOT quantity, the higher the standard of the hydraulic fluid and the higher the power to resist a excessive temperature and efficiency setting. Glycol-based brake fluids are commonest in efficiency automobiles with anti-lock braking programs (ABS). Silicone-based brake fluids are usually utilized in automobiles with hydraulic brake programs and NOT ABS know-how. One of these fluid is hydrophobic and won’t soak up water.

What’s the distinction between DOT 4 and DOT 5.1 brake fluid?

Whereas each DOT 4 and DOT 5.1 brake fluid are glycol based mostly, which implies they’re appropriate with one another and might be simply blended with out damaging the brake system, they do have a key distinction of their viscosity degree. For brakes to carry out reliably and constantly, brake fluid should keep a relentless viscosity over a variety of temperatures, together with excessive cold and hot. automobiles with anti-lock braking programs (ABS) and traction or stability management.

It is because these programs usually use micro valves and require speedy activation. DOT 4 fluids have a a lot increased viscosity restrict of round 1800 mm2/s. The upper the worth, the harder it’s for the fluid to move and if the worth is excessive when the air temperature is low, the fluid might have a unfavourable impact on ABS efficiency. Subsequently, DOT 5.1 fluids are typically really useful for highway and racing automobiles that use ABS.

How usually ought to brake fluid be modified?

Most efficiency automobiles use glycol-based fluids that aggressively soak up moisture. Because of this virtually instantly, when the seal on the brake fluid bottle is damaged, the product absorbs moisture from the air after which, when it’s in your system, from the rubber hoses and seals inside your automobile. For this reason you need to keep away from opening the brake fluid reservoir and all the time seal fluid bottles tightly. This absorbed moisture can change the efficiency traits of the brake fluid.

Because of this, brake fluids usually have very excessive boiling factors (to fight this), however as moisture is absorbed, the boiling factors drop. If brake fluid boils (and turns to gasoline), it’ll lose its capability to transmit energy. This may partially or fully disable braking, compromising efficiency and most significantly security!
