The Right Fluids For Your Vehicle

March 1, 2021 by Denver Express Car Care

Big advances in automotive technology have led to the development of high-tech fluids to keep pace. A simple example of this is the cooling system.  For decades it was primarily made out of iron, steel and rubber hoses.  There was one kind of coolant that protected these components from corrosion.

Today, cooling system components are made with various metal alloys and plastics.  These materials require different additives to protect them from corrosion.  Since the materials used vary from manufacturer to manufacturer, we now have a number of different kinds of coolant.  So it’s very important that you choose the right one for your vehicle.  If you pour in the wrong kind, it won’t protect the cooling system and may even void the warranty.  Of course, your friendly and knowledgeable pros at Express Car Care will know the proper coolant to use.  If you’re concerned you may have used the wrong fluid, be safe and have your service center flush your system and start fresh with the right fluid.

Brake fluid is confusing for some drivers.  For a very long time, most vehicles used Dot 3 brake fluid.  Now we have Dot 4 and Dot 5.  Some people mistakenly think the higher numbers are an upgrade.  The natural assumption is, if 3 is good than 4 must be better.  That’s not how it works.  They are different formulations to meet the requirements of differences in brake systems.  Only one of them will be recommended for your vehicle.

Transmission fluid is done the same way.  With the tremendous engineering advances in automatic transmissions, there have been several new types of fluids developed to protect and lubricate them and it’s important to choose the right fluid for your vehicle.

Nowhere are the advances in automotive fluids more evident than in motor oil.  Many new weights and formulations have been created to meet the demands of today’s modern engine design.

Modern engines have more parts and much tighter tolerances.  Every year, vehicle engines make more power and get better fuel economy.  But with all the added sophistication and complexity, they still have to be durable.

That’s where the new grades of engine oil come in, they have to be formulated to lubricate, protect and clean all of those engine parts, big and small.  The oil has to be thin enough to get into small passages, yet resistant to vaporization.

Your vehicle may have come from the factory with synthetic oil, transmission fluid, brake fluid, differential fluid, etc.  If so, your recommended service intervals will be based on synthetic-type fluids and you should use the same type when your vehicle is serviced at Express Car Care in Denver.

Because grades of oil and types of coolant, transmission fluid, brake fluid, and every other fluid used in your vehicle are so carefully matched to the vehicle, take care to always use the right fluid if you are topping off at home.  Check your vehicle’s owner’s manual or ask your helpful service advisor.  Using the wrong fluid can cause costly damage.
