Hi-Line Autocare Guide To Using the Correct Fluids in Your Vehicle

Today’s Hi-Line Autocare post focuses on using the proper fluids for your vehicle. Significant advancements in automotive technology have lead to the development of high-tech fluids to keep modern cars operating at peak performance. This is due to both engineering advances and new high-tech materials used to build sedan automotive systems.

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.

Now 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 among sedan vehicle manufacturers, we now have a number of different kinds of coolant.

It’s essential for East Irvine car owners to use the right coolant. Hi-Line Autocare Guide To Using the Correct Fluids in Your VehicleIf you pour in the wrong kind, it won’t protect the cooling system and may even void the warranty. Check your sedan owner’s manual. Of course, your Hi-Line Autocare automotive advisor will know the proper coolant for your vehicle.

Brake fluid is confusing for some East Irvine drivers. Back when we opened Hi-Line Autocare 25 years ago, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some Orange people mistakenly think the higher numbers are an upgrade. You know, if 3 is good then 4 must be better. That’s not how it works. They are different formulations to meet the demands of differences in brake systems. Only one of them is designed for your sedan.

Ditto for transmission fluid. For decades there were two basic types of tranny fluid used at Hi-Line Autocare: friction modified or not. With the tremendous engineering advances in sedan automatic transmissions, there have been several new types of fluids developed to protect and lubricate them.

Nowhere are the advances in automotive fluids more evident to East Irvine auto owners and Hi-Line Autocare professionals than in motor oil. Many new weights and formulations have been created to meet the demands of today’s high-tech sedan engine design. Modern engines have more parts and much tighter tolerances. Every year, engines make more power and (thankfully!) get better fuel economy. And along with all the complexity and sophistication, 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 sedan engine parts, big and little. The oil has to be thin enough to get into little passages, yet resistant to vaporization.

At Hi-Line Autocare in Orange, we believe that in some ways modern automotive fluids are just as impressive as the new engines. Because weights of oil and types of coolant and transmission fluid are so carefully matched to the vehicle, make sure you always use the proper fluid if you are topping off at home.

Check your sedan owner’s manual or ask your East Irvine service technician.
The wrong fluid can cause damage to your sedan engine. If you drive a car or truck around CA with 75,000 miles or more, consider high mileage formulations. These fluids contain extra detergent to clean dirtier older engines as well as additives to condition seals and gaskets. That’ll help prevent leaks. Always be sure that the high mileage fluid is the same weight or type of fluid recommended for your sedan.
