Lucas Auto Care's Automotive Blog
Everyone in Houston, TX knows we are advised to go to our Houston dentist twice a year. Oral-conscious Houston 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 Houston folks understand the wisdom of using this system for handling dental care, why do many resist when facing the same system for our essential car maintenance?

Following the vehicle manufacturer’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 Houston motorists to keep it all straight – even if you’re part of the 1% of the TX drivers that read their owners’ manual.
And if you have more than one European Car, the complexity is multiplied. You’d need a computer to keep track of everything. Well, that’s how your service center Houston does it. For example, Lucas Auto Care 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 Houston weather conditions, altitude, and where and how you drive in TX. Talk about these things with your honest Lucas Auto Care service advisor and you may decide that the severe service schedule in your owner’s manual is more appropriate.
Since anything that’s not expressway driving in moderate Houston weather is considered severe, most of us do at least some of that around Houston, TX 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 European Car is a blend of base oil and special additives. There are detergents to clean the inside of your European Car 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 auto manufacturer’s maintenance recommendations include both a time and mileage element – like 3 months or 3,000 miles, whichever comes first.
It’s easy for Houston drivers 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 harmful 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 Houston don’t realize how harmful it is to skip an oil change. There are a lot of dangerous 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 Houston motorists. 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 honest Lucas Auto Care service professional. Fess up – you’ll feel better. And he can help you get back on track. Following recommended intervals is the key to keeping your European Car on the road and avoiding expensive repairs.

Have you noticed an increase in price when you get a flat fixed in Houston or your tires rotated? It might be the result of your TPMS, or Tire Pressure Monitoring System.
The federal government began requiring a TPMS system on 2008 model year passenger vehicles and light trucks. Some 2006 and 2007 models may have them as well. The system has a warning light that is mounted on the dashboard that will go on if one of the tires becomes severely under inflated.
Why the new requirement? Because underinflated tires are the number one cause of tire failure. Tire blowouts cause harmful and sometimes fatal accidents. Underinflated tires also need longer stopping distance and can skid, both of which also present dangers on TX roads. Many flat tires can also be prevented by proper tire inflation, and though this may seem an economic consideration, Houston motorists who have changed a flat on the side of the road recognize that this has serious safety concerns as well.
Advances in tire technology, specifically the development of radial tires has made it harder for Houston motorists to recognize when a tire is underinflated. At a recommended pressure of 35 psi, a tire is seriously underinflated at 26 psi. But the tire doesn’t look low on air until it reaches 20 psi. This raises concerns about vehicle owners being able to tell when their European Cars are a safety hazard on the road. Hence, the TPMS.
So, like seatbelts, the important TPMS system is expected to save a lot of lives. The technology has been in use in race cars for years, and now it’s being mandated for all passenger cars, SUV’s, mini-vans and pick-ups. Besides warning Houston drivers when their tires need air, the system is required to indicate when it is malfunctioning.
This increased safety won’t come without increased costs to Houston motorists. Estimates regarding the cost of maintaining the TPMS on your vehicle run from $27 to $100. Also, there will be an added cost for tire repair. Houston service centers have had to purchase new scanning equipment to work with TPMS sensors and other vital equipment to repair tires and wheels equipped with TPMS. Lucas Auto Care technicians have to be trained to use the new equipment. These costs will have to be passed on to Houston car owners.
Further, whenever a tire is changed, the Lucas Auto Care tech will have to deal with the TPMS. Sensors will have to removed, then re-installed and re-activated. Sometimes the act of changing a tire will damage a sensor, and it will need to be replaced. These extra services will come at an added charge to Houston drivers.
Tire rotations will require that the TPMS be re-programmed. And whenever a vehicle’s battery is disconnected, the TPMS will require re-programming as well.
The TPMS itself will require attention – it contains batteries and sensors that will wear out and need to be replaced.
So, if you’ve noticed an increase in the cost for car care at your Houston tire center, it may not be the economy. It could be the cost of the TPMS in newer vehicles. Before you dash off an angry letter to Congress, however, stop and consider what you’re paying for. If predictions are correct, the TPMS will save lives, and that will be a benefit to all of us.
Of course, no warning system will save lives in Houston if motorists don’t pay attention to it. And remember that the warning doesn’t come on until the tire is severely under inflated – you still should check your tire pressure at least once a month. Houston drivers can prevent accidents and potentially save lives without a warning system by keeping their tires properly inflated.
Most Houston motorists know that tires wear out and that the wear has to do with tread depth. Most of us have heard that “bald” tires are dangerous, but most of us picture a tire with no tread at all when we think of a bald tire. And when we take our vehicles in for preventive maintenance, the technician tells us they’re need to be replaced long before all the tread is worn off. Just how much tire tread wear is too much? And how can you tell? Tires are pricey and their condition is important to the safe handling of a vehicle, so it’s essential for Houston car owners to know the answers to these questions.
First of all, it’s important to understand that there may be a legal limit to tread wear. If your tires are worn past this limit, you have to replace them to be in compliance with TX auto safety laws. That’s why measuring your tread wear is part of a vehicle safety inspection.
In some jurisdictions, tread must be at least 1.6 millimeters or 2/32 of an inch thick. This standard has been in effect since 1968. But this standard has recently been called into question, and some Houston auto owners are arguing that it be changed.
The safety issue that has brought this standard under scrutiny is the ability of a vehicle to stop on a wet surface. When a vehicle has trouble stopping, most Houston drivers immediately look at the brakes as the source of the problem. But tires are crucial to safe stopping distances because they provide the traction required in a stop.
A tire’s contact with the road surface creates traction, which allows for effective braking. On a wet surface, a tire only has traction if it can get to the road’s surface. So tire tread is designed to channel water out from under the tire to allow it to stay in contact with the road. If the tire can’t shift the water, then it starts to “float.” This condition is called hydroplaning. It is very dangerous for Houston car owners since the vehicle won’t stop no matter how hard the driver presses the brakes. Steering control is also lost.
A recent study tested the stopping ability of a passenger car and a full-sized pick-up on a road surface covered with only a dime’s depth of water (less than a millimeter). The vehicles were traveling at 70 mph (112 kph) when they stopped on the wet surface. At 2/32 tread depth, the stopping distance was double that of a new tire. The passenger car was still traveling at 55 mph when it reached the stopping distance it experienced with new tires.
Let’s suppose that you’re on a busy Houston freeway in a light drizzle and a vehicle stops suddenly in front of you. You just bought new tires and you brake hard, missing the vehicle with only inches to spare. If you hadn’t bought those new tires, you would have crashed into that vehicle at 55 mph. That is a major difference.
What if your tires had a tread depth of 4/32? You would have crashed into that vehicle at 45 mph. Still not a good situation. But it’s better.
Now what if you were driving that pick-up truck? You wouldn’t have missed that vehicle in the first place, and you would have crashed at higher rates of speed in both of the other scenarios. The heavier your vehicle, the longer its stopping distance. It’s a matter of physics.
The results of this test has led Consumer Reports and others to ask that the standard for tread wear from 2/32 to 4/32. The increased standard will improve safety on the road and save lives here in TX and nationally.
Of course, until the standard changes, you’ll have to decide whether you’ll be willing to replace your tires a little sooner.
You can use a quarter to tell if your tread wear is down to 4/32. Place the quarter into the tread with George’s head toward the tire and his neck toward you. If the tread doesn’t cover George’s hairline, you’re under 4/32. With a Canadian quarter, the tread should cover the digits of the year.
You can measure the 2/32 tread wear with a penny. If the tread touches the top of Abe’s head, it’s at 2/32. Tires are a significant item for Houston auto owners when it comes to car care. But their condition has a major impact on safety. We need to decide whether to sacrifice safety for economy. Keeping our tread wear above 4/32 is good auto advice.
Improved fuel economy has two benefits for Houston car owners: less fuel is necessary and fewer emissions are released. Spring cars and trucks run cleaner than ever. Houston motorists may not realize that the first federally mandated pollution control device came out almost fifty years ago.
TX car owners that were around in the early 60’s may remember that the PCV Valve came out on 1964 model cars. PCV stand for Positive Crankcase Ventilation. The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine.
When fuel is burned in the European Car engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.
Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to dangerous sludge. Sludge is like Vaseline and clogs passages in the engine leading to damage.
Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in Houston.
Enter the PCV valve. It’s a small, one-way valve that lets out the detrimental gases from the crankcase, and routes them back into the air intake system where they are re-burned in the engine. Fresh air comes into the crankcase through a breather tube. This makes for good circulation in the crankcase. And that gets the dangerous air out. As you can imagine, however, the valve gets gummed up over time.
Spring drivers that skip oil changes now and then will notice that the PCV valve gets gummed up even faster. If the PCV valve is sticking in your European Car, the gases won’t circulate as well, leading to increased pressure in the crankcase. That, in turn, can lead to oil leaks. Fortunately, the PCV valve is very inexpensive to replace at Lucas Auto Care in Houston. Some can even be checked by your honest Lucas Auto Care advisor.
Your European Car manufacturers usually recommend they be changed somewhere between twenty and fifty thousand miles. Unfortunately, PCV valve replacement is left out of some European Car owner’s manuals, but at Lucas Auto Care, we will make sure your PVC is replaced if needed.
All of us Spring car owners can do our part for the environment. Watch that lead foot, stay on top of our essential automotive maintenance and don’t forget to replace our PCV valve.
Unless you live in Death Valley, you really don’t hear much any more about cars overheating. That’s because cooling systems in vehicles have been much improved. That doesn’t mean you can’t overheat your European Car engine, though. Without proper preventive maintenance, you could still find yourself on the side of the highway in Houston waiting for your European Car engine to cool down.
When you service your cooling system at Lucas Auto Care, your service professional will check the condition of the coolant. It can become corrosive over time, which can damage a radiator — leading to an overheated engine. Changing the coolant periodically is good car care. Your European Car owner’s manual can give you guidelines on how often to replace it.
If your engine overheated, your honest technician will also check your coolant system for leaks. Check the European Car radiator for cracks and the radiator hoses for leaks. He’ll also check your water pump. They don’t need to be replaced on a regular schedule, but they do need an inspection regularly. They can and do wear out.
The water pump is a critical component of your European Car cooling system. It pumps the coolant to keep it circulating through the engine. The coolant is cooled in the radiator, then it travels through the engine, where it absorbs heat, then it returns to the radiator, where it releases the heat. And so on. But a water pump is something of a misnomer. The fluid pumped through your European Car cooling system is not just water. It also contains coolant, which is actually poisonous. You should never consider your radiator as an emergency water supply.
There are many types of coolant. It varies from vehicle to vehicle, and using the wrong kind could damage your engine. Your service advisor will know which kind your vehicle’s manufacturer recommends. The team of automotive professionals at Lucas Auto Care is always a good source for auto advice. We’ve been providing quality automotive services at our convenient location in Houston for 10 years.
Keeping your cooling system in good repair will help keep your engine running well, and keep you out of the Houston repair shop. This means that a regular cooling system inspection should be on your schedule for routine preventive maintenance of your vehicle. Your owner’s manual will tell you how often you need to do this. It varies depending on what kind of car you drive, what type of driving you do and where you live in TX.
At Lucas Auto Care, we help you keep your cool which will keep you in the driving lane.
