Courtesy Automotive Service Guide to Using the Correct Fluids in Your Vehicle

Courtesy Automotive Service Guide to Using the Correct Fluids in Your Vehicle

Today's Courtesy Automotive Service post focuses on using coolant.  If you pour in the wrong kind, it won't protect the cooling system and may even void the warranty. Check your vehicle owner's manual. Of course, your Courtesy Automotive Service service advisor will know the proper coolant for your vehicle. Brake fluid is confusing for some SAN CLEMENTE drivers. Back when we opened Courtesy Automotive Service, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some SAN CLEMENTE residents 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 vehicle. Ditto for transmission fluid. For decades there were two basic types of tranny fluid used at Courtesy Automotive Service: friction modified or not. With the tremendous engineering advances in vehicle aut ... read more

The Courtesy Automotive Service Basic Guide To Synthetic Oil

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it. Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used. Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials. Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer ... read more

Fall and Spring Checkup in SAN CLEMENTE

When I was a kid, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it's about time to get into Courtesy Automotive Service for a checkup and he said that he read on the internet that modern cars don't need seasonal service. My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense. Back when my dad was teaching me about how to take care of the family vehicle, most of them used a different weight of oil in the winter and in the summer. But most of today's modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes. Your owner's manual or SAN CLEMENTE service advisor at Courtesy Automotive Service can tell you the right oil to use. Of course, you're concerned about the coolant or ant ... read more

Talk to Courtesy Automotive Service About New Shoes for Your Vehicle

Custom wheels are one way that SAN CLEMENTE folks express themselves and personalize their vehicle. But they aren't as cheap and easy as sticking decals on your back window. There are several factors that need to be considered, including cost, the fit of the wheel, modifications that will have to be made to the vehicle, how the new wheels and tires will affect the operation of the vehicle, your driving habits and, of course, the style of the wheels. Most SAN CLEMENTE drivers start with the last factor: the style of the wheels. But that should be the last thing we choose. When considering custom wheels, you should first carefully consider your budget. Some wheels may require adjustments to your vehicle suspension system, brakes, or traction systems. You need to know what you can afford before you start shopping or get your heart set on a particular type of wheel. There are three basic ways you can change your wheels. First, you ... read more
