Category Archives: Service Intervals
Most people in the Nashville area are aware that automotive manufacturers have recommended service intervals. Following recommended service intervals is very important. The engineers that design our vehicles have tested the various systems and components to meet durability and safety standards. Some of these standards are self-imposed and others, like those for emissions components, are government mandated for the areas around Mount Juliet, Nolensville and Hermitage in Tennessee.
The maintenance schedules are designed to achieve the standards. Think of the benefits of following recommended intervals as falling into three general categories: Protection, Efficiency and Safety.
Protection. Let’s start with motor oil. First of all, the engineers recommend a particular weight and type of motor oil for your sedan. All of their oil change recommendations assume using the proper motor oil. Motor oil contains detergents and other additives that clean the engine and provide corrosion resistance. Over time, the additives are depleted. The oil also becomes contaminated by water, dirt and combustion gases.
Extending your interval beyond the recommendation means that your sedan engine will be operating without the full protection of fresh motor oil. It also means that sludge can form in contaminated oil and clog up passages in the engine, starving parts from needed lubrication.
Efficiency. Some services are designed to keep automotive systems operating efficiently. For example, the fuel system gets clogged up with gum and varnish from the fuel. Fuel doesn’t flow efficiently which reduces fuel economy. A fuel system cleaning restores the fuel system’s efficiency and increases your gas mileage.
Safety. Your brakes are obviously one of the most important safety systems on your sedan. The manufacturer has scheduled brake pad replacement as well as power brake fluid drain and replacement intervals. Because brakes are so important, a brake inspection is also on the schedule to head off problems before they result in an accident.
Check your owner’s manual for recommended service schedules or talk with your Mount Juliet service advisor at Conder’s Automotive by calling 615-758-1515. You’ll find our shop located at 441 East Division Street in Mount Juliet, Tennessee 37209.
You may be surprised to learn that various inspections may be on your list of factory recommendations for your sedan. These inspections are usually at major intervals like fifteen or thirty thousand miles. They’re designed to uncover important parts that may be close to failing.
Your sedan owner’s manual can tell you when to change your oil, but it can’t tell you that you have a radiator hose that’s bulging and about to burst. For that you need a trained auto technician. These scheduled inspections are in addition to the multi-point inspections done with a full-service oil change.
Everyone in Mount Juliet, Tennessee knows we are advised to go to our Mount Juliet dentist twice a year. Oral-conscious Mount Juliet residents have a teeth-cleaning and examination. Once a year, we get x-rays to look for problems that can’t be seen with the naked eye. When our dentist is done, he/she tells us what was found – “Everything’s fine, see you in six months.” Or “You’ve got a small cavity starting, let’s schedule an appointment to take care of it.” By the time you leave, you have a plan for addressing any necessary issues.
This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big expensive problems. And you avoid those huge bills.
If Nashville folks understand the wisdom of using this system for handling dental care, why do many resist when facing the same system for our vital car maintenance?

Following the auto maker’s recommended intervals can be confusing. First, there are recommendations for so many things: oil changes, transmission, coolant, air conditioning, power steering, brakes, fuel system, filters, belts, hoses, alignment, rotation, balancing …you get the point.
Every item has a recommended interval and it’s hard for Mount Juliet drivers to keep it all straight – even if you’re part of the 1% of the Tennessee drivers that read their owners’ manual.
And if you have more than one sedan, the complexity is multiplied. You’d need a computer to keep track of everything. Well, that’s how your service center Mount Juliet does it. For example, Conder’s Automotive subscribes to automotive databases that have your vehicle’s recommended intervals. You may have wondered how they know what else to recommend when you take your car in for an oil change – it’s all in the database.
Well, it’s not all in the computer. There are other variables that can’t be accounted for in the schedule. Things like Nashville weather conditions, altitude, and where and how you drive in Tennessee. Talk about these things with your friendly Conder’s Automotive service professional and you may decide that the severe service schedule in your owner’s manual is more appropriate.
Since anything that’s not highway driving in moderate Nashville weather is considered severe, most of us do at least some of that around Mount Juliet, Tennessee and it should be taken into account.
Let’s take your basic oil change as an example – what issues are involved? The oil you put in your sedan is a blend of base oil and special additives. There are detergents to clean the inside of your sedan engine and corrosion inhibitors. A good quality motor oil will not only lubricate your engine, it will help it stay clean inside and run cooler.
Now, these additives deplete with use and time. That’s why most car maker’s maintenance recommendations include both a time and mileage element – like 3 months or 3,000 miles, whichever comes first.
It’s easy for Mount Juliet car owners to think, “Gee, I’ve only driven 2,000 miles in the last 3 months. I can wait on that oil change.” But you need to remember that the inside of your engine is a dangerous environment. The oil is contaminated with combustion by-products that starts degrading its effectiveness even when it’s just sitting there.
A lot of people in Mount Juliet don’t realize how harmful it is to skip an oil change. There are a lot of harmful metal parts moving around in your engine. Small bits of metal wear off and are floating around in your oil. They can be carried to more delicate areas of the engine where they cause damage. Your oil filter is designed to trap metal particles and other dirt, but if it’s clogged up because you haven’t changed it, it can’t trap any more.
Oil sludge is another problem for Mount Juliet car owners. Sludge is oil that has turned to a gunky jelly – think ‘Vaseline’. Obviously, sludge doesn’t lubricate. It can also clog small oil passages so that all the parts don’t get properly protected by the oil. That’ll lead to premature wear.
If you’ve missed some oil changes, don’t despair. Just talk with your friendly Conder’s Automotive service advisor. Fess up – you’ll feel better. And he can help you get back on track. Following recommended intervals is the key to keeping your sedan on the road and avoiding costly repairs.

People near Mount Juliet Tennessee often ask Conder’s Automotive how often they should have a particular service done. It’s a great thing to ask. You can look at your owner’s manual, or have your Mount Juliet Tennessee service advisor at Conder’s Automotive look up your vehicle in a service database. What you find is often a surprise to people – there are actually two service schedules.
One is the regular schedule and the other is the severe service schedule. Service intervals are shorter on the severe service schedule. When asked, most folks in Mount Juliet Tennessee will say that their driving is normal and that the ‘regular’ schedule probably applies to them. ‘Severe service’ sounds pretty extreme – ‘I don’t drive like that’.
Well, here is what the manufacturers say constitutes severe driving conditions; you can draw your own conclusions.
- Most of your trips are less than four miles.
- Most of your trips are less than ten miles and outside temperatures are below freezing.
- The engine is at low speed most of the time – not on the highway. You operate your vehicle in dusty areas.
- You regularly tow a trailer or carry heavy loads.
- Drive with a car-top carrier.
- Stop and go driving.
- Driving in very hot or very cold weather.
If that’s severe driving, what constitutes regular driving? Well, it would look something like this: I live somewhere with moderate temperatures all year round – I’m thinking San Diego here. And I live close to a freeway on-ramp. Everywhere I need to go is right off the freeway, at least four miles from my home. I can drive at a steady 60 miles per hour when I’m on the freeway.
I don’t know about you, but that doesn’t sound like my normal driving. It sounds more like ideal conditions. I live where it gets hot in the summer and cold in the winter. I run short errands around Mount Juliet. Occasionally we load up for family trips.
For me, normal driving includes elements of severe service driving. So here’s what I tell people: think about how you drive, where you live, where you go and what you are expecting to with your vehicle in the near future.
Picture a line with ‘regular’ on one end and ‘severe’ on the other, and make a judgment on where you fall. If your regular oil change recommendation is 5,000 miles and the severe service recommendation is 3,000 – when should you change your oil? For me, it’s closer to 3,000 miles. For my wife, it’s closer to 5,000 miles. Your Mount Juliet Tennessee auto service advisor at Conder’s Automotive will be happy to have this discussion with you and help you sort it out.
Just a quick word on why severe service intervals are shorter. One has to do with heat. That can either be external heat from the weather or engine and transmission heat from stop and go driving or working extra hard moving heavy loads or towing. The heat causes the fluids like oil and transmission fluid to break down more quickly and then they aren’t as effective.
Another factor is water. Moisture naturally collects in fluids as they cool. In your motor oil, for example, if you don’t drive long enough for the oil to fully heat up, the water won’t evaporate. Water in the oil can lead to the buildup of damaging sludge.
If you live where the air is dusty or polluted, fluids will become contaminated and filters will get dirtier more quickly.
So make an honest evaluation of your driving conditions. You’ve made the commitment to take care of your vehicles, so it only makes sense to follow the right schedule.
Nowadays, Mount Juliet auto owners are paying more at Nashville gas pumps. For some families in the greater Nashville area, it adds up to several hundred dollars every month. That’s got to come out of the budget somewhere. This is one of the reasons many Tennessee auto owners are putting off buying a new car. They plan on keeping their old vehicle for a year or two longer than before.
Even now, 2/3 of the personal vehicles on our local Mount Juliet, Tennessee interstates have over 75,000 miles on them. The average age of vehicles is over nine years. And most people in Nashville can’t afford to be stranded or inconvenienced by a break down. So following a regular maintenance schedule, like personal diet and exercise plans, is actually critical to preserving your investment.
Determining what to do for a higher-mileage vehicle can be challenging because many vehicle manufacturer’s manuals don’t publish service intervals after 60,000 miles. Thus, Mount Juliet drivers need to be better at keeping records and planning for preventive maintenance.
You can start by figuring that services with a recommended interval should still be performed on that interval, even after you’re past the tables in your service manual. For example, a service might be recommended every 15,000 miles. Well, just keep doing it every 15,000 miles for as long as you have your car.
Now higher mileage engines operate under more stress. Some Nashville automotive experts suggest that the severe service schedule is more appropriate and that routine service should be performed at shorter intervals. Check with your owners’ manual or service advisor at Conder’s Automotive to see if the severe service schedule is right for your vehicle.
And keeping current with your full-service oil change schedule is important for a couple of reasons. First, older engines have had more time to build up oil sludge. Skipping an oil change here and there can really compound the problem for your sedan.
Another equally important reason is that your other fluids are routinely checked and topped off. Power steering fluid, brake fluid, coolant and transmission fluid can be kept at optimal levels even though the older seals and gaskets are leaking more than when they were new.
And speaking of older seals and gaskets: they start to dry out and become more brittle with age. You may want to consider using high mileage formulation oil and fluids. These products contain key additives to condition seals and gaskets to keep them from leaking. The high mileage formulations cost more than standard products, but they are well worth it in terms of preventing serious repair bills down the road.
Older vehicles in the Mount Juliet, Tennessee area need repairs and replacements that newer ones don’t. Things like timing belts, radiator hoses, suspension work, anti-lock brakes, air bags, water pumps, alternators and batteries. That may seem like a lot of stuff to have done, but it works out to be cheaper than new car payments.
With a high-mileage sedan, a couple of relationships will become pretty important to Mount Juliet car owners. The first is with your service specialist at Conder’s Automotive. You need someone you trust to take care of your car and be mindful of your needs. Ask for help to develop a plan to keep your vehicle road-worthy that works within your budget, and for the Mount Juliet, Tennessee area driving conditions.
The next relationship is with your vehicle itself. We’re not talking about naming your car or tucking it in at night. We just mean – pay attention and get to know your vehicle. Notice unusual sounds, smells, vibrations, etc. Then you can describe the changes to yourservice specialist at Conder’s Automotive and head off problems. We can’t do anything about the price of gas, but we can properly maintain Old Faithful to keep it safely and economically on the local Mount Juliet, Tennessee roads.

Let’s talk about deciphering the auto service menu board. Mount Juliet, Tennessee service centers like Conder’s Automotive have a board that lists the routine services they provide. But some people don’t know what these services really are unless they ask. Let’s go down a typical list, in alphabetical order, starting with air conditioning service.
Feel free at any time to give Conder’s Automotive a call at 615-758-1515 to learn of the many services we offer, or stop by our Mount Juliet, Tennessee auto center at 441 East Division Street 37209.
First remember that all of these services are recommended by vehicle manufacturers. They set how often or at how many miles the service should be done.
Air conditioning service involves purging the old refrigerant and capturing it for proper disposal. Then fresh refrigerant is installed. The fresh refrigerant will lubricate the system and will also help it cool better.
Alignment. Service centers like Conder’s Automotive make sure all four wheels are lined up and track with each other. This reduces tire and suspension wear and improves safety and handling.
Battery service. Service centers like Conder’s Automotive inspect the battery for corrosion, leaks or damage. Test the battery’s ability to hold a charge. If the battery’s still strong, clean it up. If not, replace it.
Brake service. This could be two things. A brake inspection to see if the brakes are working well mechanically and to see if the pads are still safe. If not, replace the pads and make any repairs that might be in order.
The other thing is to evacuate the brake fluid, clean out the system and replace it with fresh fluid. This is important, but often over looked.
Cabin air filter. The cabin air filter is the filter that cleans the air that comes into the passenger compartment. It works like the filter on your furnace at home. It gets dirty and needs to be changed often.
Cooling system. This is the cooling system for your engine. Replace the old coolant with fresh to protect your radiator and other cooling system components from corrosion.
Differential service. Every vehicle has at least one differential. They don’t require service very often, so people don’t think of them much. The differential transfers power from the drive train to your wheels. Drain the old fluid and add fresh lubricant.
Engine air filter. This filters the air that’s burned in the engine. It also gets dirty and needs to be replaced often.
Fuel filter. This filter cleans the fuel before it gets to the engine. Like the other filters, it too gets clogged and needs to be replaced in order to maintain good flow.
