Today’s Texas Express Lube & Auto post focuses on using the proper fluids for your vehicle. Big advances in automotive technology have lead to the development of high-tech fluids to keep pace. Some because of engineering advances and others, advances in the materials used to build truck 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 from manufacturer to manufacturer, we now have a number of different kinds of coolant.
And it’s important that . car owners use the right coolant. If you pour in the wrong kind, it won’t protect the cooling system and may even void the warranty. Check your truck owner’s manual. Of course, your Texas Express Lube & Auto advisor will know the proper coolant to use.
Brake fluid is confusing for some . drivers. Back when we opened shop 7 years ago, 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. 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 recommended for your truck.
Transmission fluid is the same thing. For decades there were two basic types of tranny fluid used at Texas Express Lube & Auto: friction modified or not. With the tremendous engineering advances in truck 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 . motorists and Texas Express Lube & Auto professionals than in motor oil. Many new weights and formulations have been created to meet the demands of today’s modern truck engine design. Modern engines have more parts and much tighter tolerances. Every year, engines make more power and get better fuel economy. And with all the complication 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 truck engine parts, big and little. The oil has to be thin enough to get into little passages, yet resistant to vaporization.
At Texas Express Lube & Auto, we believe that in some ways modern automotive fluids are just as great feats of engineering as the new engines. Because weights of oil and types of coolant and transmission fluid are so carefully matched to the vehicle, take care to always use the proper fluid if you are topping off at home. Check your truck owner’s manual or ask your . service advisor. The wrong fluid can cause damage. If you drive a car or truck 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 vehicle.
