Make Sure Your Engine Stays Protected with Regular Oil Changes

One of the best and most affordable ways to keep your car or truck running longer is with regular oil changes and oil filter replacements.

The oil in your engine serves several purposes, including:

  • Performing up to 40 percent of your engine cooling: Motor oil absorbs heat from certain areas and redistributes it to prevent the buildup of excessive heat in your car’s oil content.
  • Preventing internal engine corrosion: Without clean oil in the right amount, your engine may be vulnerable to rust and corrosion.
  • Lubricating moving components to prevent damage from friction and excessive heat: Oil has additives that reduce friction and provide a protective layer on engine components.
  • Cleaning your engine: Motor oil absorbs debris and dirt, keeping it from building up on engine components, which is a crucial step in ensuring all engine components are functioning optimally.

If the oil in your engine is low quality or contaminated, or if the oil level is low, you can experience catastrophic engine problems. That’s why regular oil change service is so important.

The oil change schedule can vary for your car or truck, depending upon your manufacturer’s recommendation, your vehicle’s age and your regular driving habits, such as frequently towing or hauling heavy loads or making frequent short trips. Our expert oil change technicians can recommend a schedule that’s in the best interest of your vehicle based on your driving habits.

Frequently Asked Questions

  • Does the oil filter need to be replaced with every oil change?

    Your new, clean oil won’t stay that way for long if you have a clogged, dirty oil filter. These filters help the oil stay clean for many miles, but there comes a point where they can’t hold any more dirt or debris. When that happens, you’ll end up running unfiltered oil throughout your engine and reducing all of the protection that clean oil provides. Oil and oil filter changes are relatively inexpensive, so make sure you don’t put off your next oil change.

  • Can I change my own oil?

    Most of our customers come to us because our auto service is fast and convenient, but there are several other reasons to forego doing it yourself. In addition to running the risk of overlooking an oil leak, you may not have the easy access you expect to the areas you need to reach, such as the oil filter and oil pan bolt, for instance. It’s also unlikely that you’ll be able to dispose of the old oil properly or that you will notice other problems with your vehicle.

    To make sure the job is done right, come to Reliable Automotive. Our expert technicians will make sure you have the type of oil and filter that are ideal for your car or truck, and they’ll do a visual inspection of your hoses, brake system, tires, and other important parts of your car without a bunch of added fees to let you know of any potential issues so you can stay informed of your vehicle’s health and take care of any small problems before they become big headaches.


  • What is synthetic oil?

    Many drivers aren’t familiar with the different types of oil available on the market today-conventional and synthetic. “Synthetic” oil may refer to full synthetic oil or a synthetic blend. Here’s what you should know about the differences in the types of motor oil:

    Conventional motor oil is derived from crude oil and doesn’t have any additives. It does its job well, but it’s important to adhere to a regular schedule of oil change service to ensure your engine is staying protected. It breaks down or degrades more quickly than synthetics. Synthetic oils are man-made. Full synthetic oil contains a synthetic base plus additives that enhance its performance and its ability to protect your engine.

    Semi-synthetic, or synthetic blends, are a mix of a synthetic base with conventional kinds of oil. There is more than one type of full synthetic oil, with each having a different blend of additives and providing various degrees of durability and cleaning power.

    If you’re unsure which type of motor oil is best for your car or truck, don’t worry-the pros at Reliable Automotive can make a recommendation and answer any questions you may have. We’ll make sure you only purchase exactly what you need to keep your vehicle running great.

  • How often should I check my oil?

    Because oil is critical to keeping your engine clean and running properly, the oil level should be checked about once a month, and you may also want to check it if you’re about to take a long trip. If you find that your oil level is low month after month, you may have an oil leak. Make an appointment at your nearest Reliable Automotive location for a leak check and a change of your oil and filter.

  • Do I have to go to the dealer for an oil change to keep my warranty?

    In nearly every instance, you’re not required by your warranty terms to have your oil changed or get any other type of auto repairs or service at the dealership. At Reliable Automotive, our ASE-Certified technicians have the same expertise that you’ll find at a dealership. Check your warranty to verify maintenance requirements (you may need to use a certain type of oil and filter), then schedule an appointment for your oil change at Reliable Automotive.

  • Can’t I just top off my oil instead of having it changed?

    While you may need to add some oil from time to time, keeping it topped off does not do anything to protect your engine from the harmful effects of dirty oil. As you add fresh motor oil, it blends with the old oil, so it’s much less effective than a complete change. You will still have sludgy oil circulating throughout your engine, leaving your engine components susceptible to damage from excessive friction and heat buildup.

    Keep in mind that if you’re having to top off your oil frequently to get it back up to the designated level, you may have an oil leak. Make sure you have a leak-free system and fresh, clean oil in your engine by scheduling an oil change service appointment at Reliable Automotive’s Buda, San Marcos, or Kyle location.

  • Can I switch to a different brand or kind of oil than the one I’ve been using?

    Yes! Our technicians will be glad to recommend the right oil for better protection and performance than your previous type of oil. In general, if the oil is in line with the oil and viscosity that your vehicle’s manufacturer specifies, making a change to a different type or brand of oil won’t cause any issues.

  • How can I tell if my oil is bad?

    Take a look at the oil on the dipstick. Look to see if it appears milky or has clumps in it, and check to see if it feels gritty. Even if you have a late-model vehicle with a digital display of how much life you have left in the oil, a quick check of the dipstick is always a good idea.

  • Why should I go to Reliable Automotive instead of a quick oil change shop?

    We know you have plenty of options for oil change service, including “quick lube” shops. That’s one reason we go beyond a fast oil change to give our customers extra value and exceptional customer service. While you have your car or truck at Reliable Automotive for your oil change, we’ll also check several of your engine’s major components. If we discover any issues, we’ll give you a clear estimate and be able to take care of any repairs or additional services you may need.
