Is filling your tires with nitrogen better than filling them with oxygen? The short answer is: “Yes”.
Here’s the science to support that fact. You may be surprised to learn that the air we breathe is roughly 78% nitrogen and 22% oxygen. That same air mixture gets pumped into your tires every time you fill up. You may be thinking, “Well, if it’s 78% already, shouldn’t that be enough? I mean, does 22% oxygen really make that much of a difference?” Again, the short answer is: “Yes”.
The key is how much oxygen gets displaced by that extra nitrogen. When the nitrogen content is increased from 78% to 99%, the oxygen content drops from 21% to less than 1%. The reason that this is good is that oxygen really isn’t that great for your tires to begin with. The problem with oxygen is that it expands when the tires get hot, this causes over-inflation and actually leaks out of the tires’ sidewalls at a much faster rate than nitrogen which is a much larger molecule. Ironically, this naturally occurring “over-inflation” directly causes “underinflation” which contributes to the degradation of the rubber. As if that isn’t enough, plain air contains water vapor which is corrosive to the metal rims as well as the tire pressure sensors.
Nitrogen has been used for many years in aircraft tires, racing cars and military vehicles, but how does it affect the average passenger car? Well, that really depends on the type and the amount of driving you do, as well as how faithfully you check your tire pressure. Not everyone has tire pressure monitors, though they are becoming standards on most new vehicles.
Your best bet is to give our service department a call and we can evaluate and advise you on whether or not nitrogen filled tires are right for you and your driving habits and circumstances.
One would think that some of the smaller components, such as those little vent windows wouldn’t cost too much to replace…that is until you’ve actually broken one. Of course, everyone knows that there are many components of automotive glass on the car that will largely differ in cost. Lots of individuals don’t understand how much the tiny vent window on a new or used car in Dallas may cost to fix.
Here’s a scenario you may have experienced:
You’re running behind for the most important meeting of your life and after switching off your car, you grab the keys and put them on the passenger seat while you collect your notes. After this you hop out of the vehicle and click the lock button on the door prior to shutting it. As you are actually letting go of the door, you remember your keys sitting in the front…but it’s too late. The door slams and is now locked…with your keys inside. Now what? Call a locksmith? Nope, there’s no time. So you choose to break the small vent glass and take care of the cost later…after all, how much can that actually cost?
So your meeting is over and you now need to contact and arrange an autoglass replacement for that small vent window you decided was your key back into your car. Of course, after talking with the autoglass center, you find out that the little vent window you broke is one of the priciest parts of glass on your automobile. D’OH!
What people don’t understand is that the vent window might be small compared to the other glass on the car but it is not often mass produced like the windshield or door window. Quite often, the vent window will need to be special ordered which means the manufacturer will likely need to commit additional time to custom cut this piece of glass. The vent window normally consist of lots of curves which will also increase the time it will take to custom cut the window.
Therefore should you find yourself in a bind and feel you must break a window on your automobile then you should bust the door window rather than that small vent window. The vent window can ultimately cost you 2 or 3 times what it would cost to replace the door window. Sad but true.

The other day I wrote about bearing noise coming from your front wheel drive car. It usually sounds like a constant “hum”. Today I want to cover a different noise: Clunking or clicking when you take a turn. Let’s say that you’ve already determined that something is wrong with your wheels. But, what exactly is it? Do you hear a clicking noise when you make a turn? Do you see grease around the tires? If you do, these are symptoms of a problem with your car’s axle system. The axle system is simply what enables you to turn and move the wheels. When the axle goes bad, you may also feel extra tension when turning the steering wheel.
If this sounds like it could be your auto repair issue, watch the video below with Mechanic’s Master Mechanic, Michael Renteria for a more detailed explanation. Michael, an ASE certified technician, explains why your car’s axle system is throwing grease (cracks in CV boot) and why you’re hearing clunking or knocking.
Now if you’ve found that you believe that you are having an axle problem like described in the video above, you are going to want to bring in your vehicle as soon as possible as to avoid causing any further damage to your front axle. Bring your GM vehicle by Freeman Grapevine and we’ll check it out for you.
Everybody wants to have a vehicle that lasts forever, or at least long enough to give the vehicle to your oldest child when they go off to college. One thing to remember is that the moment you drive the new vehicle off the lot is when your car’s factory scheduled maintenance begins.
Having regular factory maintenance inspections ensures that your vehicle will be working at its best as any issues can be addressed before they become serious issues. Your vehicle maintenance will consist of basic scheduled service and intermediate scheduled service.
75,000 Mile Service Check
The 75,000 mile service check is an intermediate scheduled inspection that isn’t as intensive as a major service check but the inspection involves more than just checking and changing your vehicle’s oil. Most mechanics and dealerships will perform many of the same services, with added tweaks to stay competitive against other service centers. Here are some of the basic things that are done during the 75,000 mile service check.
Visual Inspection: A good mechanic will visually inspect areas of the vehicle that experience the most wear-and-tear. They should inspect all belts, hoses, suspension bushings, brakes, and motor mounts. The vehicle will also be inspected for leaks, unusual noises when in operation and strange noises that may indicate a problem.
Filter Replacements: You’ll have the oil and filter replaced, the engine air filter checked and perhaps the cabin air filter changed.
Recall Issues:Freeman Grapevinewill also check if your vehicle falls into the manufacturer’s recall list for any significant problems that need to be fixed so the driver won’t be put at risk while out on the road.
Some other maintenance your service technician may perform include tire replacement, shock/strut replacement, and replacing the drive belt. In addition, a safety inspection will also be performed so that you are rest assured you will be driving a tip-tip vehicle out on the road. If any leaks are noticed, the service technician will be able to find out where it is coming from and fix the problem.
So keep an eye on your odometer and make sure to schedule your 75,000 mile factory maintenance inspection so that your vehicle can be checked for any potential problems. With this inspection, your vehicle will last for a very long time without needing extensive major repairs due to negligence.
I would say that the majority of people know that regular scheduled maintenance is a necessity when it comes to owning a car to keep it running properly. One of the most common maintenance produces is getting oil changed. A no -brainer, right?! Well, you’d think so, but there are a handful out there that just don’t get their oil changed. And then they end up with some major, and sometimes even irreversible damage to their vehicles engine.
But enough about the importance of oil changes. Another important maintenance procedure you need to have done is getting your tires rotated. Now this one I can understand being overlooked….sometimes! For some reason, people seem to always forget about the tires, which is crazy to me because they are the ones doing the ground work…no pun intended!
Keeping your tires properly maintained not only keeps you safe…very important, but also helps you to get the most wear out them as well. And if that’s not enough, rotating your tires also helps you get better gas mileage as well which all adds up to saving money, and, in this economy is a very important thing.
If you find that you have trouble remembering to rotate your tires, I suggest you add it in when you get your oil changed. To get the most of your tires, you want to keep them on a regular rotation so that they wear evenly. But even more frequently, you should at least check the tire pressure. Driving with low tire pressure is unsafe and can make your tires more susceptible to flats and punctures and can even make driving your vehicle challenging.
If you need a service shop, then of course I recommend giving Freeman Grapevine a try and I guarantee you won’t be disappointed. And of course you’re always welcome to come check out our great selection of new and use vehicles too!
It doesn’t take your car repairman to tell you that, if you’ve hit your 60,000 mile mark and haven’t had your fuel injectors cleaned, it’s probably time to do so. I don’t need to tell you that the cleaner your fuel injectors are, the more efficient your engine will be, whereby resulting in better gas mileage. With fuel prices seemingly stuck at well over $3 a gallon, this just means more money in your pocket. What happens when fuel injectors are dirty or clogged is that they don’t spray in an even pattern. This will produce poor fuel ignition and is a huge waste of fuel. Check out the video below. This is a great report on fuel injectors.
Replacing fuel injectors can cost several hundred dollars so you don’t want to neglect them, as they are the feeding tube for your engine and you are going to want as much efficiency as possible. It’s a good idea to get them serviced at least once a year. Remember, following your regular maintenance schedule will prove to greatly benefit the life of your car’s engine.
It can be one of the most annoying noises your car, or truck can produce. That CLUNK when you turn the wheel of your vehicle. The issue here could actually be a number of things. There can be 5 things that can cause a front end clunk.
Take a look at the video below for a quick explanation how each of these components can be the culprit of causing that front end clunk.
If you’ve exhausted the entire list of potential problems above, remember it could be your control arm bushings. As was said in the video, these are pretty heavy duty bushings, so you probably have put a LOT of miles on your vehicles.
If you aren’t really sure how to check your GM vehicle’s suspension system for the noise that you know is coming from “somewhere up there”, go ahead and bring in your car at anytime. We’ll be able to diagnose and fix your front end clunking quickly and efficiently. Front end suspension is always taking some extreme abuse from pot holes and poorly maintained road, so it will probably require some adjustment at times. Letting it go may only create problems in the future.
Ok, how do you know when you may require replacement shocks and why are shocks so essential? These are excellent questions. This is certainly an frequently overlooked but crucial piece to your automobile in regards to safety. make no mistake, recognizing when it is time to switch your shocks is extremely important.
First, let’s evaluate the shocks as well as the suspension system:
Examining your shocks is often a very simple thing to perform. The truth is, it is something you can do yourself fairly easily.
The very first thing that can be done is pay attention if you are driving. For example, upon hitting the bump does your car or truck continue to bounce up and down? If the answer is yes then you definitely will almost undoubtedly require fresh shocks. Start taking note now, as this will likely start slowly and get worse over time until they are really bad. In reality, if you delay too long you may break other components and parts of of you vehicle.
Another approach to test your shock’s life would be to physically peek underneath your car or truck. For a truck or van you might not be able to see them. In this instance you need to push on the bumper and follow the measures the same as you are physically taking a look at them. They may bounce. Two or three bounces they are fine. If they continue to oscillate, then they need replacing.
As stated before, the main reason it is so important to change worn out shocks is because they’re critical to keeping your tires connected with the highway. If you are driving down a bumpy road and the wheels are bouncing up and down, worn shocks will in fact permit the wheels to entirely lose contact with the highway. Considering your tires are the only thing separating you from the highway, this can be particularly unsafe when you run into a dip or a bump during a high speed curve. Superior shocks will help to minimize body roll, also essential during cornering.
IF you think that your shock may be worn and really can’t figure it out by yourself, swing by and we’ll take a look at them. Then we can recommend the right types for your Buick or GMC.
Freeman Grapevine is wondering: “Do you know what can happen if you don’t change your oil regularly”? I can already hear the grumbling.
“Yes Ozzie, our engines will have to work a little harder. No big deal, these modern cars can handle that sort of thing.” Really? Take a look at the video below. The car that is the subject of the video is all of 5 years old and it looks like someone has poured tar into the engine. Don’t believe me? Take a look for yourself.
Oil changes viscosity under the extreme and constant pressure, heat and friction your engine produces. Over time, your oil will begin to solidify and turn to a gunky tar that puts your engine’s life at risk quite literally. An engine that hasn’t had regularly scheduled oil changes is subject to a catastrophic malfunction, or break down. You could be looking at a total engine replacement, and that is not a cheap repair. In fact, cleaning the engine when it has reached this state is similarly expensive procedure.
I know I’ve written about this before, but I really want you to get the most out of your Buick or GMC vehicle, and in order to do so, that means regularly changing your oil. It really is a very simple and inexpensive thing to do.
If you haven’t had your oil changed in the past 5,000 miles, then it’s time to bring your new or used car into Freeman Grapevine and get it done. Remember, it’s going to cost you a lot more money the longer you neglect your engine’s necessary oil changes.
Do you suspect you have an oil leak? You must, or you wouldn’t have that nasty stain in your driveway. The hard part is trying to figure where the oil leak is coming from. There are a number of places that engine oil may leak in your car.
The main place your engine is going to leak is from the bottom of the oil plug. There is a quick fix for fixing a leaky oil plug, is to get a fiber gasket and uses that to help seal the leak. If the issue is more serious, you are probably going to want to bring it into Freeman Grapevine, so we can take a look at it.
As you can see from the video, that oil leaks can happen in a number of places and might require the advanced diagnostic techniques from a master mechanic. Remember, an oil leak of any kind should be addressed and fixed as soon as possible. Give your Dallas Fort Worth Buick GMC dealer a call today.
