If you’ve walked through the automotive fluids section of an auto parts store, you’ll know how overwhelming the sheer number of products available can be. How do you know what’s right for your vehicle?
As you know, these fluids all serve a function in making your car run. Your vehicle manufacturer has specified a particular type of fluid for every system from the motor, to the cooling system, brake fluid and so on. When you realize that not every variation is applicable to your vehicle, the task becomes more manageable.
First let’s talk about why there are so many varieties. Starting with motor oil, we see that manufacturers match the properties of a particular weight or type of oil with the design needs of the engine. For example, engines with sophisticated valve trains often require a thinner weight of oil.
Some vehicles come from the factory filled with synthetic oil and the recommendation to use it for life. The safe bet is to always use what the factory recommends. The recommendation is what‘s been proven to work in function and durability tests. The recommended oil is also a factor in determining oil change interval schedules.
A good quality oil has more additives that are engineered to clean and protect the engine. They cost a bit more but are worth the extra protection. If you buy budget oil, you might want to consider shortening your oil change interval.
Sometimes fluids are developed specifically to meet the needs of a particular family of engines. An example would be coolant. Because of the different materials used to build the cooling system, the coolant must be formulated to protect those parts, which vary from manufacturer to manufacturer, from corrosion. We’ve seen special coolant for General Motors, Volkswagen, Chrysler and others.
The same is true of transmission fluid and brake fluid in recent years.
The good news is that your service center has databases that tell them the recommended fluids for your vehicle. This takes all the guess work out. If you have some special needs, like a higher mileage engine or want enhanced performance, ask your service advisor for upgrades or additives that’ll meet your needs while being consistent with the manufacturer’s recommendations.
Of course, your full-service oil change will top off your fluids. But it’s a good idea to have some of everything at home in case you need to top something off yourself or to take on a trip. Ask your service advisor or check your owner’s manual for fluid specifications.
