How to Maintain Your Car Battery

Not sure how you can maintain your car battery?

While you may be quite strict about keeping your car clean and supported from the outside, you may have been ignoring under the hood too often. 

If so, chances are you’ve been neglecting your car battery and denying the car what it needs to working properly.

After all, of what use is a sparkling, well-kept car if it doesn’t even start in the morning, making you late for work?  

Obviously, all of your effort into making sure your car remains spotless on the outside would definitely be pointless in this scenario.

 As such, making sure your battery is in tip-top shape is imperative.

Easy task

Still, it’s not like maintaining your battery is too difficult a task to complete. You only really need to check on it once every 2-3 months and perform only a few simple tasks to take care of it.

So, here are all the things you need to do to take care of your battery:

Checking the level of water every 2-3 months

Though checking for water levels is pointless if your car uses a maintenance-free battery , if you’ve got a wet-cell non-maintenance-free battery installed in your car, you’d need to check the fluid levels every 2-3 months or so.

If you want to check the fluid levels, you should unscrew/open the fluid caps and see whether the water levels are below the designated mark.

If so, carefully fill up the battery with distilled water, taking care not to overfill it. Replace the cap when you are done, and you will be good to go.

Protecting the battery from high temperatures

If you find protecting your battery from cold weather important to prevent freezing, you should just as well protect it from extremely high temperatures.

Usually,the car battery quality depreciates faster in extremely hot temperatures than in extremely cold temperatures.

Nevertheless, protecting the battery from heat isn’t really that hard of a task. All you need is some heat resistant grease to slather over the battery exterior, or even get an insulator to cover your battery.

Both of these would work just fine to form a barrier between your battery and unwanted heat to guard against damage

Cleaning off the battery terminals of battery acid corrosion

Now, dried-up acid corrosion on terminals is one of the most common battery problems you will encounter when taking care of your battery.

Ordinarily, your car battery produces hydrogen gas that reacts with the terminals to leave unwanted, disgusting bluish-white gunk on your battery terminals.

So, you need to clean this off if your battery is to perform optimally. Prepare a paste made of baking soda and water and apply it on a wire brush which you’ll use to scrape off the gunk gently.

Safety first

Be sure to don protective gear like face masks and goggles when performing this task; you don’t want to be inhaling this stuff or letting any of it brush off and fly into your eyes.

Though it does need to be said that this is one problem you can’t completely solve. You’ll have to clean this gunk off your car battery time and again.

The silver lining here though, is that you only need do so once every 6-8 months.

Checking your battery’s voltage and recharging when necessary

You can almost always tell if your battery is running low before it dies out. This is picked from indicator panels and dimming headlights.

The most effective way, however, is using a voltmeter. This way, you are sure to determine the exact power left in your battery. It just gets the guesswork out of the way, making you more aware of the state of your battery.

As long as your battery levels are close .to 12.5 or 12.6 V, you’re not in the woods yet.

Use a trickle charger

If you do need to charge your battery, however, take your car to an auto electrician or charge it from home using a trickle charger.  This allows you to avoid the additional service costs altogether.

Though taking your car to the auto shop is important at least once every 6-9 months, there are some things you can’t completely take care of on your own.

How To Maintain Your Car Battery Conclusion

Your car battery is one small component of the car. Its purpose, however, cannot be discounted. A faulty battery, just like a flat tire, can be such a thorn in your flesh. 

However, with these insights, you are sure to be a couple of steps ahead of any eventualities of a faulty car battery.

Preparations You Should Make Before Using a Catalytic Converter Cleaner

Cleaning your car’s catalytic converter using a catalytic converter cleaner is not a messy process as many people imagine.

As long as your car still runs by burning fossil fuels, it will produce pollutants like carbon dioxide, nitric oxide, and carbon monoxide gases.

CO2 is a greenhouse gas that is mainly responsible for global warming since it absorbs heat from the sun and traps it in the atmosphere. Carbon monoxide, on the other hand,  is lethal to humans when present in high levels. This makes the later more damaging to both humans and the environment immediately it leaves the tailpipe of your car.

Catalytic converters are devices that are fit onto the car’s exhaust system. They convert harmful emissions like CO and NO into to CO2 and nitrogen respectively.

When your car fails an emission test, it means that it is not emissions compliant. This is something that your OBD-II should be able to indicate. This happens because the catalytic converter is either degraded or it is dirty from carbon buildup that accumulates over time.

In order to improve the efficiency and durability of your catalytic converter, it is necessary that you clean between 2 to 4 times a year depending on the size of your car. This involves the use of a catalytic converter cleaner.

A catalytic converter cleaner is a chemical that strips away carbon that accumulates on the surface of the catalyst. The use of this cleaner is simple, but you need to start by making proper preparations as follows:

Find out the cause of your high emission levels

In order to extend the lifespan of your catalytic converter, it is important to clean it regularly. Clogging of the converter with carbon from the car engine minimize or block the contact between the catalyst and harmful gases for conversion.

Sometimes the cause of high emissions may not be related to the catalytic converter but a poorly maintained engine or bad tuning. However, display of OBD2 error codes like P0420 and P0430 will indicate that the problem is in the catalytic converter which needs to be cleaned or replaced.

Find out the cause of the carbon buildup

High emission level is usually caused by excessive carbon build up. Carbon build up is a process that you cannot prevent. But you can slow it by driving within the revolution limit that gives the best MPG fuel economy. Also, make sure that your tire pressure is at the right level.

The buildup is accelerated when the air-fuel ratio is less than the optimum in a situation commonly known as a ‘fuel rich’ situation.

This simply means that your car engine is not burning all the fuel as expected. For this reason, it is necessary to check the condition of your spark plugs. Replace them if necessary before you proceed to clean your catalytic converter.

Buy a good quality catalytic converter cleaner

When your emission problem stems from a clogged catalytic converter, you need to find the best cleaner to restore it. With a huge number of cleaners in the market, you will need to go through their features and reviews to settle on the right one.

The most important feature to look out for is the ability to greatly reduce CO and NO emissions as well as remove accumulated carbon and dirt from the converter and engine.

A good catalytic converter cleaner should work on all vehicles whether diesel, gasoline or hybrid. While no miracle cleaner is best in everything, you may need to try out a few products. Find the best one with time.

Prepare to clean your catalytic converter

After confirming that your converter needs cleaning and have found a good quality cleaner, it is time to prepare for the actual cleaning.

The first preparation at this stage is to ensure that your gas tank is almost empty. The next step is to pour the cleaner into the gas tank in order to blend with the remaining fuel. After this, you need to drive your car normally for at least 50 miles nonstop before filling the tank full.

It is important to ensure that the levels of dangerous emissions that your car produces are always at the minimum. Not only for compliance purpose but also to protect the health of people and the environment.

Catalytic converter cleaners do work, and it gets even better when you use a good quality brand. Clean your converter regularly and always ensure that your car is in good condition.

How to Match Wheel Locks and Your Vehicle

You have probably seen a car sitting on a set of concrete or brick blocks after the wheels and tires have been stolen. Whether you have factory wheels or aftermarket ones, owning a set of wheel locks is a low-cost opportunity that will help ensure wheels stay on your vehicle. Wheel locks replace the standard lug nuts on your wheels. They feature a specific face pattern that only works with a special key.

Fortunately, you can swap out the standard lug nuts for security wheel locks easily without taking a trip down to the dealership or auto repair shop.

The wheel locks are difficult to open if you do not have the special key. Thus, making them some sort of cheap insurance policy for your wheels and tires. However, you need to ensure that the wheel lock key is with you at all times so you can take the wheel and tire off when needed.

As you can imagine, there are many options when it comes to wheel locks on the market – with almost similar design and style. Here are five things you should look into to identify the best wheel lock for your vehicle.

Thread Size

Wheel studs are threaded bolts – or studs – that protrude through holes in your car’s wheels and onto which you thread the wheel or lug nuts. Most cars have either four or five studs for each wheel. But some SUVs, vans and trucks may have up to eight of them on each wheel.

When looking for wheel nuts, the first thing you need to consider is the thread size. You can get the measurement of the thread size using a simple thread pitch gauge. Alternatively, take one of the standard lug nuts to a local hardware store and spin into it bolts they have in store.

Thread diameter or size is the measurement of the outside diameter of your wheel stud threads. You can find them in standard (1/2” or 7/16”, and more) or metric (14mm or 12mm, and more) measurements.

The commonest thread sizes for cars are 5/8”, 9/16”, 1/2”, 7/16”, 14mm, 12mm and 10mm. You can find your vehicle’s thread sizes on its manufacturer website or owner’s manual.

Thread Pitch

Thread pitch is the measurement of the distance between threads in millimeters in metric applications or threads per inch in non-metric applications. Using the thread pitch gauge, you can easily identify your vehicle’s thread pitch measurement. However, if your car has already been modified, it’s worth verifying the thread pitch before you purchase a lug nut wheel lock set.

Seat Type

The seat refers to area where the lug nut makes actual contact with your car’s wheel surface. The most common wheel seat types are:

  • Acorn or tapered cone seat
  • Mag seat with washer
  • Ball seat
  • Flat seat
  • Spherical or ball seat
  • Extended thread (ET)
  • Tuner style
  • Small diameter spine drive

It is critical that you match the lug nut seat to the wheel seat. Using the wrong type will likely see your wheel not seat properly, causing vibration and loosening of the lug nuts.

Length or Dimensions of Wheel Locks

It is vital that you confirm your wheel locks or lug nuts dimensions so you get the proper fit for both aesthetic and safety purposes. The measurements you need to take into account include the outside diameter and overall length.  Also, you need to determine the proper shank diameter and depth for mag style locks and nuts.

Finish or Color

The good thing is that lug nuts and locks are available in an assortment of colors and finishes. These varieties include blue, red, silver, yellow chromate, zinc, stainless steel, black chrome and chrome plated. Once you have had a chance to consider all the fitting measurements, all that remains is choosing the best wheel locks according to your preferred style.

Final Word

Most wheel locks on the market are sold in packs of four under the assumption that you install a lock on each wheel. This is sufficient for many car owner requirements. However, some companies offer wheel locks in sets of 20, allowing the total replacement of the lug nuts.

Best Fuel Injector Cleaner for Optimum Vehicle Performance

​Driving your own car makes you feel having the freedom to go anywhere you want and at any time you want. But along with owning a car is having the responsibility in taking care of it. In the case of fuel efficiency and engine performance, using the best fuel injector cleaner can make a huge difference for your vehicle.

What is a fuel injector?

A fuel injector is a valve that consists of a body that houses an electromagnetic coil and a sealing mechanism, which is kept closed by a spring. The injectors should either be fully open or fully closed. The amount of fuel that is injected determines how long the injector is open or how long the ball, disc, or pintle is removed from its seat.

This internal device is extremely important as soon as you start your vehicle up. When the fuel injector malfunctions, expect to experience several issues ranging from fast depletion of fuel to engine block noise and motor chatter.

One of the primary culprits in problems related to fuel injectors is cleanliness. No matter how oil companies promise clean fuel, there’s bound to be particulate matter than may get mixed into the fuel. Over time – and especially when the fuel line isn’t maintained – the particles may build up, thereby causing a lot of issues in your car engine.

The easiest way to address this particular issue problem is to use a fuel injector cleaner.

​What is a fuel injector cleaner?

A ​fuel injector cleaner is an additive that keeps fuel lines clean, protects the fuel injectors, and boosts fuel efficiency and mileage. When a fuel injector fluid is added to the fuel mix, particulate buildup in the fuel line and injectors will be dissolved.

Different factors may cause your fuel injectors to be clogged. Hydrocarbons and additives evaporate at different temperatures. Some amount of gasoline may be left behind the tip of the injectors each time the engine is turned off.

In addition, the volatile compound in the fuel may evaporate, leaving a residue on the injector tip. When it accumulates, it may start affecting the spray pattern and fuel distribution. As a result, the overall performance of the engine may be affected.

A fuel injector cleaner is an additive that keeps fuel lines clean, protects the fuel injectors, and boosts fuel efficiency and mileage. When a fuel injector fluid is added to the fuel mix, particulate buildup in the fuel line and injectors will be dissolved.

Choosing The Best Fuel Injector Cleaner

If you use your vehicle often, you need to check the fuel injectors from time to time as well.  A service may be required in the following instances:

  • Detonation which can lead to catastrophic engine failure
  • Failed emission
  • Increased fuel consumption
  • Poor performance
  • Pollution
  • Poor idle
  • Smoke from the tailpipe
  • Surging and bucking under light throttle

The quality of gasoline may sometimes be inconsistent. This may cause build-up, and lead to inefficient ignition and poor power output.

What could make it all worse is that the high output engines are sensitive to deposits that accumulate on fuel injectors, intake valves, intake ports, and in combustion chambers. With this, it can cause an increase in fuel consumption, poor performance, and increased exhaust emissions.

The easiest and fastest way to address these issues is to use the best fuel injector cleaner to keep your vehicle in tiptop condition.

A complete fuel system cleaner eliminates dirt and deposit from more than just the injectors. This should contain powerful ingredients and solvents to be able to thoroughly clean the whole system.

To be certain that you are purchasing the right fuel injector system for your vehicle, you need to look at a couple of factors.

Alcohol vs. polyetheramine (PEA)

Alcohol-based products are often used for old vehicles to get rid of years of deposits in the entire system. However, this is best performed by mechanics, and is already considered an obsolete practice.

For most modern running vehicles, polyetheramine will work as the best fuel injector cleaner component. This compound is a premium fuel additive known for its high fuel cleaning action on direct fuel injectors and fuel lines.


Some of the best fuel injector cleaner variants are strong enough to clean decades of solid buildup in fuel lines and injectors, while others are designed for milder approaches. Know first the status of your vehicle (i.e. if it has been in operation for quite a number of years already) before choosing a fuel injector cleaner based on strength.

New car models don’t need too strong compounds to clean the fuel injectors. Doing so may actually do more harm than good, as the strong components may affect the integrity of small moving parts inside your vehicle. In short, being too clean-conscious may end up damaging your car instead of maintaining it.


Don’t be fooled by an expensive product, but don’t choose cheap ones instead. Focusing on price may not always lead you to the best fuel injector cleaner that your vehicle needs.

Having said that, ask around for a variety of the best fuel injector cleaner products in retail shops, and compare their features and prices. In the long run, you will be able to determine which fuel injector cleaner will fit best for your vehicle’s needs and your intended budget.

Frequency of use

Some fuel injector cleaners are designed for one-time use, while others need to be added each time you fuel up. These product types have varying price points, but try to estimate how much you’ll be spending with frequent usage comparing to a one-use product.

Engine suitability

Some of the most efficient fuel injector cleaners are not designed for diesel engine vehicles. Make sure to check for the compatibility of the product with your vehicle engine. Either ask the manufacturer or retailer about the product’s suitability for your car engine or do a quick online search for product specifications.

Using an incompatible fuel additive may create a lot of unwanted issues on your vehicle.

Enclosed instructions

Never buy a fuel injector cleaner that does not come with usage instructions. There’s a lot that you will probably miss out if you fail to follow instructions on how to properly use the product. Remember that while some of the best fuel injector cleaners are quite expensive, damaging your vehicle by not following usage directions will be more costly.

One significant detail that injector cleaners indicate in the label is the required fuel level before pouring the product in. Most products of this kind work optimally when you maintain a particular fuel level (as indicated by your vehicle’s fuel gauge).

Another important instruction has something to do with the right timing to start your vehicle. If you start up your car too soon, the product may not have slid down through the fuel line and injectors yet. Check the instruction manual for the recommended wait time before using your vehicle.
