What Are the 6 Essential Vehicle Fluids?

Vehicle Fluids

If you aren't aware of the importance of fluid maintenance, then you might want to start learning. Similar to the water we consume, your vehicle needs various fluids to stay active and driving. If these six fluids aren't regularly inspected and topped off, your automobile will be at risk of lower performance, gas mileage, and value, as well as a higher risk of a breakdown or collision. 

What are the 6 Essential Fluids?

The six essential fluids that every car needs are engine oil, transmission fluid, brake fluid, coolant, power steering fluid, and windshield washer fluid.

Engine Oil

Engine oil, also referred to as motor oil, is the most vital fluid of all. As you may know, its primary job is to lubricate and protect your engine's components from overheating. As a responsible vehicle owner, you should know which type of oil your vehicle takes. You can find the oil specifications for your car in the owner's manual if you are unsure. There are 3 main types of motor oil: conventional, semi-synthetic, and synthetic. When it is time for your next oil change, bring your vehicle to our shop for quick service.

Transmission Fluid

Similar to engine oil, transmission fluid serves to lubricate your transmission. This fluid is usually a red color. If you notice that the fluid status is low or contaminated, you should have it changed or flushed immediately. If you can't locate the reservoir, do not hesitate to bring your vehicle to Guthrie's Auto Service for your next transmission fluid flush service.

Brake Fluid

Without this essential solution, your vehicle would not be able to slow down or come to a complete stop. If you start to notice a brake delay or unusual feeling with your brakes, you should first check your brake fluid levels. At our auto repair shop, we offer professional brake flushes to help properly maintain your vehicle. 


Engine coolant aids in cooling down your engine by absorbing excess heat and taking toxic byproducts out of the exhaust system. Without coolant, your engine would simply overheat. We recommend regular coolant flushes to help prevent major repairs down the road.

Power Steering Fluid

The power steering fluid is a powerful solution that ensures you ride around smoothly. If your power steering fluid is running close to empty, your car's steering wheel will start to stiffen up, making it difficult for you to make turns. Running low on this liquid can be very dangerous, which is why you inspect this fluid at least twice a year.

Windshield Wiper Fluid

Windscreen washer fluid is employed to clean the windshield of your car. It is often overlooked, but it is crucial for safe driving. Without this liquid, you could experience trouble seeing through your dirty windscreen.

It would be best if you examined all the fluids in your vehicle at a minimum of every oil change interval. If you need any of these solutions flushed or topped off, please bring your car to our expert team at Guthrie's Auto Service Inc.
