Oil Filter Warning

The oil filter is one of the most important parts of the engine, as it filters out any contaminates created by normal wear and the engine’s heat. When your car has the oil changed, most likely the oil filter is also changed – at least I hope so.

Oil Filter Warning

Years ago, we all knew that the oil and filter were changed at 3,000 miles; that was just the way it was. Enter the new age of cars, oils, and filters, especially synthetic oils which last much longer, as stated in some of my previous articles. Many oil changes can last 5,000 to 10,000 miles depending on the type of car, type of oil, and how many quarts of oil are in the oil pan.

Back in the day when we recommended the 3,000-mile service, any oil filter would easily protect the engine for that mileage, but not many oil filters would protect your car for more than 5,000 miles. If you are driving longer than 5,000 miles between oil changes and using a low-cost oil change shop, you may be damaging the engine and not even know it.

Why Does It Matter?

Let me explain. Oil filters all look the same on the outside but are very different on the inside. The difference lies in the amount of filtering material used and the type of drain-back valve used inside each filter. Less expensive filters, as you would suspect, have less filtering material and a less reliable drain back valve.

This may seem insignificant, but the results can be catastrophic. When you drive longer than 5,000 miles on one of the low-cost filters, the filter starts to lose the ability to keep the contaminates contained and they slip into the engine bearings, causing premature wear. The eventual outcome is engine failure. It does not pay to have an inexpensive oil change and an inexpensive oil filter put in your newer model car.

Currently, there is not a standard or law that says what part, or quality of part, needs to be put in your car. If you have an engine failure that should be covered by a warranty, and you have been using cheap oil/filter, this is not only scary for you, the consumer, but it could get downright ugly as the manufacturer may deny the claim. Ultimately, you should be aware of what is going on with the car and use a service center you trust.

A cheap oil change may save you money short term, but it won’t save you money in the long run.

Unnecessary Service

Unnecessary Service

I hear the phrase “unnecessary service” and wonder what that means. We visit the doctor for physicals, we visit the dentist for cleanings, we have our home air-conditioning unit cleaned and checked, a yearly eye exam and of course, the car needs a checkup too.

All of these professionals recommend some kind of service or checks to keep everything working properly. Most shops recommend services on cars that come in to their bays using the guidelines set out by the manufacturers or from the shops’ experience of early component failures. Sometimes there are a few recommendations and sometimes there are many service recommendations.

What Do We Suggest?

We recommend service to keep your car safe and reliable, just like the dentist tells you about issues developing with your teeth and gums. We know no one likes to spend hard-earned dollars on maintenance services, especially when after these services are performed, the car seems to run as usual with no noticeable differences.

I have found there are basically two types of philosophy on maintenance. The people who believe in maintaining and those who believe it’s better to wait until it breaks, then fix it. There are at least 30,000 parts on the average new car and over 5,000 of them are moveable parts. All moving parts require a clean source of lubricating oils, coolant, or greases along with filters set in place to catch harmful materials. In addition, we have electronic parts that can be affected by poor maintenance habits. The simplest of new cars have more computing power than the Apollo Moon Lander. In fact, you could get to the moon with just 1/10th of the computing power found in the modern car! Today’s electronics are so sophisticated that cars may run well even when there are serious failures in progress. The systems have enough authority to mask developing problems. By the time you have a detectable malfunction, one that you can feel or sense, you may have damaged expensive parts. The only outward indication the driver may get is a warning light on the dash.

How Are Your Shocks/Struts?

Shocks and struts take a beating, so we don’t have to! They help us ease the pain of driving over less than perfect roads and stabilize us over bumps, when we stop quickly, and when we go around corners. We pretty much take them for granted. Our owner’s manuals tell us they need to be inspected and/or replaced every 60,000 to 90,000 miles, depending on our driving habits. Many newer cars have computer-controlled electronic suspension systems that need inspection as well.

How Are Your Shocks And Struts

We recommend that you take some time when you are out driving around to notice a few things about your vehicle. If your car is bouncing a bit after you hit a bump in the road, nose-diving after you brake, swaying around corners, or has abnormal tire wear, then you need to have your shocks replaced.

Struts basically perform the same function as shocks, except they also are an integral part of your suspension system. If you are out and about in your car and notice the above symptoms, along with noise while going over bumps or turning corners, you might also have an alignment situation.

Other Notable Symptoms

Shocks and struts also give you another symptom if they are ready to be replaced… they leak fluid. They do a lot for us, and we certainly take them for granted until we notice our ride is just not as enjoyable or comfortable as it could be. Bad shocks and struts also cause wear and tear on our tires and our suspension components.

Make sure your shocks and struts are ready for whatever condition the roads you drive on happen to be in. Whatever your car may need, at Certified Auto Specialists, we want your vehicle to always be ready to go when you are!

How to Have a Lean and Mean Driving Machine

How To Have a Lean And Mean Driving Machine

Cars are built better than ever these days and are engineered to give us miles of service. That’s why keeping them well-maintained is critical! To stay on top of this, you need a trusted partner on your side to look out for you and your car. Here are some of the essential areas that we check during regular maintenance to keep your car running right:


It’s your vehicle’s lifeblood.  Dirty oil makes it harder for your engine to turn over and causes premature engine wear. We’ll set you up on scheduled oil changes, ensuring that your car is ready to roll down the road when you are for years to come.

Belts and Hoses 

These are made of very durable material with relatively long lives but they do deteriorate over time. They need to be regularly inspected and replaced as needed so they don’t give out when it’s inconvenient or unsafe. We do everything we can to make sure you’re never stuck on the side of the road, waiting for a tow truck.


Other than condensation from your air conditioner, your car should never leak. Your car uses 11 different types of fluid, such as antifreeze, engine oil, power steering fluid, air conditioner refrigerant, shock absorber fluid, battery electrolyte, windshield washer solvent, rear axle or CV boot lubricant, fuel and others.  Are you seeing liquid under your car? You need to bring it in right away.  


Since Henry Ford’s Model A, tires are the only thing between us and the road, so it’s essential to keep them as healthy as possible. A simple, inexpensive preventative maintenance measure is to keep your tires properly inflated and rotate them regularly. You can prolong their lifespan and improve fuel economy, a win-win! 


If neglected for too long, old unchanged coolant can corrode, leaving sediment throughout your cooling system and causing clogs. This can result in hot spots that damage your engine.


The battery cables must be securely attached and free of corrosion to get power to the starter and accessories so that the alternator receives a charge. When you come in for regular maintenance, we’ll check it out and make sure you’re getting all you can out of your battery.


Think of it this way, when it comes to fluids, our cars’ needs are similar to the human body. We need to keep our systems flushed with water to keep our bodies running well. Your vehicle needs fluids to remain healthy. Over time, these fluids get contaminated and cause corrosion. Flushing these out and refilling them with clean, fresh fluid keeps your car safe and running smoothly. It rids the system of harmful toxins and lubricates at the same time. We’ll make sure the fluids in your vehicle keep your car running right for years to come!
