Safety rules to consider when doing car maintenance yourself

Safety rules to consider when doing car maintenance yourself
By Jakob Jelling

Working on a car involves several risks which you should be aware of and prevent before actually starting the job. First of all, you should never try to work on the car and try to fix any part of it if you do not know what you are doing and how it works. One of the main things you should be very careful with when working on a car is the batteries, but there are many other things you should be careful about as well.
The car batteries contain an acid and emit hydrogen gas, which can be not only dangerous for human health but can also produce explosions. This way, it is mandatory that you do not take any ignition source, such as cigarettes, close to the car while working on it. Besides this, you should wear gloves while handling the batteries and try to avoid having any direct contact with them. Besides this, batteries can also give you shocks due to the amps they have, and you should disconnect the battery negative cable in order to avoid having problems due to this.
It is also highly recommendable that you maintain a fire extinguisher near the car and easily to reach while you are working on it. Some of the most combustible parts of the car are the engine and the batteries, so you should always be extremely careful while working on them and should not allow anyone who is smoking to come close to you or the car until you have finished.
Another important thing you should have in mind while working on the car is the existence of poison gases. Some parts of the car, such as the exhaust, contain poison gases which could be very harmful and even intoxicate you. Therefore, it is important that you avoid allowing these gases to enter your respiratory system by wearing a protection.
Also, while handling car cables it is very important that you are extremely careful on how you connect them. Car cables could cause voltage sparks and, in combination with the gases and other combustible elements it implies the danger of fire. This way, it is very important that in cases such as when you need to receive help from another car, you learn how to properly connect the cables before trying to do so as well as you maintain the car keys away from the ignition while working on them.

Your Engine, Your Baby: Synthetic or Conventional Oil

Your Engine, Your Baby: Synthetic or Conventional Oil
by: Michael Walker

One central argument between car enthusiasts and on Internet car forums alike is what oil is better for your car, synthetic or conventional. Before synthetic oils became available for regular automobiles, the argument centered solely on brand types and weight. But now, with the advent of these synthetics all over the market, what is truly the best choice for your engine? Let’s explore both of these worlds to find out.Conventional oil is rated according to a SAE system. This scale is used so that you know what type of oil is best for your car given the environmental conditions (temperature, city driving, etc.) of where you live. The first number, for example on 10W30 motor oil, is 10 followed by a “W”. This “W” indicates that the number before it is the viscosity rating of the oil. The lower this number, the better the oil is for colder climates. The higher the number, the better it is for hotter driving conditions.Synthetic oils, on the other hand (before their commercial release) were used in many military vehicles and fighter jets. Airlines also use synthetics in their engines. The synthetic oil has been designed not to break down as quickly and can tolerate extremities in temperature and weather (hot to cold).One of the major differences between conventional and synthetic oils is that synthetics are treated with more additives that protect your engine for a longer amount of time before you have to change it. And, while we don’t want to get into all the molecular chemistry involved in the making of these oils, we should mention that they also last longer in hotter conditions and won’t “gel” in colder ones, like conventional oil. In other words, synthetics have more additives, which greatly protect the car from viscosity breakdown. They are designed to withstand temperature extremes. It may be safe to say that extreme driving conditions call for the use of synthetics.On the financial side of the matter, synthetics cost a whole lot more; up to three or four times as much as regular conventional oil. But, the wonderful thing is that you don’t have to change your oil every 3,000 miles; recommended with conventional oil use. In fact, you may not have to change it until well after 25,000 and up to 50,000 miles as long as the oil filter is changed every 10,000 miles. So, the cost at first might scare consumers away, but the long-term benefits of synthetic oil use are substantial.However, you will still have to be responsible for your car’s maintenance check-up every 3,000 miles or so. With regular oil-changes, you are automatically checking over the car for other problems (or if you don’t an inspection mechanic does). It might help you find a problem that could be dealt with, that could’ve gone unchecked. Also, you’ll want to check the synthetic oil every now and then to be sure that it isn’t contaminated and/or that there isn’t any moisture build-up.With normal everyday driving, perhaps conventional oils work best for you. You aren’t driving in extreme conditions and you swear allegiance to regular oil. That may be fine. Synthetic oil cannot really offer you anything that conventional oil cannot under normal operating conditions. However, the definition of extreme driving states that if you do a lot of short driving (two to twenty miles) daily, it’s hard on your car. And, specialists agree that this constitutes extreme driving due to the faster breakdown of the structure of conventional oil.Another major reason that many are choosing the synthetic route is that it contains fewer impurities; impurities that can cause your engine harm, perhaps to the point of premature engine wear. With conventional oil, there’s no way to totally rid, filter or clean the impurities from the natural elements. That’s another reason why synthetic oils do not have to be changed as much even in extreme driving conditions.You’ll want to be careful; however, if you do decide that you want to give synthetic oils a try. If you’ve been driving your 1983 Ford Thunderbird for years using 10W30, you may not want to switch using your conventional oil brand. Conventional oils have solvents that stick to gaskets and seals and often cause them to swell a certain way. These gaskets and seals have been used to the same oil for years and the switch to any other type of oil (whether it is to a different conventional oil brand, or an upgrade to a synthetic) may be harmful. The oil you change (or upgrade to) will also have solvents and additives, different from the original. So in other terms, the changing of oils could result in oil leaks and/or a once small oil leak becoming bigger due to the reaction the seals and gaskets will have to the change (not because of the oil itself). If you think that this might be the case for you (i.e. if you have an older car using conventional oil), it’s recommended that you not try synthetic oil until you have an engine (or new car) with relatively virgin gaskets and seals that will be able to acclimate much more easily to the chemical changes of the newer type of oil.It’s easy to see that that fanfare for one or the other is an argument that has really been explored. It’s best for you to decide what will fit your personal needs. If you have an older car, you may want to wait until you upgrade. However, if you have a newer car, the benefits of synthetic oils are easily seen. Again, it’s solely dependent upon you and the conditions where you drive. Synthetics are shown to provide their best protection above 250 degrees Fahrenheit. Most people do not drive their cars this hot. However, many do drive in cities, where driving times are considered to be more of a “stop-and-go” nature, which may be considered “extreme” in many circumstances. When the time comes for you to make a decision, at least you’ll be informed of the differences of each. And, until that time, no matter what, keep up that automotive pride!

What to do when a hot engine is hard to start

What to do when a hot engine is hard to start
by: Jakob Jelling

Although usually engines exposed to cold weather is the most known problem related to car starting difficulties, hot engines might bring obstacles as well. Many people realize that the car do not start as easily as it should when the engine is hot and do not know what to do about it. In order to be able to overcome this problem, it is important to start by learning why it happens.Most of the reasons by which a hot engine would be hard to start are based on problems related to the fuel. When the engine is too hot, fuel can't circulate properly due to the way in which vapor obstructs it and therefore the engine wouldn't start as easily as it should or it wouldn't start at all.A car engine would keep on gaining temperature until a while after it was shut off. During this period of time is when the highest amount of vapor would be circulating around and therefore that is when the chances it obstructs the engine are bigger as well. This way, if you are driving in hot weather and you have just turned off the car in which you experience start problems, you should wait for a few minutes until starting it back.Fuel injected engines do not experience this problem as much as others do due to the fact that the fuel remains inside the injectors by being under a very high pressure. This way, fuel injected engines would not become so easily obtruded by vapors as other engines would and therefore the car would not have the same problems to start as another would.Also, engines might become hard to start while being hot if it coincides with the season in which refiners change from a fuel blend to another. Sometimes gasoline refiners change from a higher volatility fuel to a lower one when summer approaches due to the way in which hot weather causes fuel to evaporate easier. If refiners change back to a higher volatility fuel while the engine is still exposed to days of high temperatures, this could cause the fuel to evaporate too much creating too much vapor and therefore obtruding the engine.

What is Fleet Maintenance Management?

What is Fleet Maintenance Management? -
by: Jennifer Bailey

Fleet Maintenance Management is a critical position in any company that has a number of commercial vehicles. The individual responsible for the management and maintenance of fleet vehicles performs a variety of functions. It is imperative that companies such as delivery drivers or even taxi services know what is going on with their vehicles at all times. Preventative maintenance, order/vendor logging and fuel economy are among a few of the issues that fleet maintenance managers deal with on a daily basis. One of the most important duties of a fleet maintenance manager is the maintenance of vehicles. With the number of vehicles many companies have on the road each day, maintaining quality vehicles is important. Regular and controlled fleet vehicle maintenance can assist in more efficient and lower cost repairs, fewer technical problems and more efficient tracking, management and budgeting of the fleet. An outstanding fleet vehicle maintenance program can save time and money by ensuring that vehicles are safe and on time. Repairs and downtime for fleet vehicles can cost your company a considerable amount of money. High-quality fleet vehicle maintenance can mean the difference in your company’s reputation being one of top-notch service rather than undependable service. Preventative maintenance and scheduling routine maintenance or repairs can extend the life of your fleet vehicles. Many fleet vehicle managers find that using a specialized software program is the best way to organize these needed elements. With the high cost of fuel today, fleet managers also take into consideration the fuel usage among the vehicles. Fleet maintenance software programs often have features that enable the manager to appropriately budget for gas. The ability to log and track the mileage of drivers can give the manager a good idea of the average fuel consumption of each vehicle in the fleet. Fleet maintenance managers occupy important positions within a company. Most managers within top U.S. companies recommend the use of high-quality fleet maintenance software programs. These programs enable the fleet managers to keep detailed records and logs of everything that happens with each vehicle. For companies whose primary service depends on well-maintained vehicles, organization and tracking of the fleet and expenses is obviously a key responsibility. Your company’s business reputation is important and it is essential that the fleet manager is able to accurately maintain an exceptional level of quality of all vehicles in your fleet.With all of the products available on the market, the fleet maintenance management needs to examine the company’s needs to find the product best suited for them. The manager may choose to examine some of the top products by taking advantage of free trials offered by most companies. During the free trial, you are generally capable of performing the full range of functions in order to get a good feel for the product. This is a critical first step in choosing the software program that is right for your company About the author:Fleet Maintenance Software Info provides comprehensive information on fleet maintenance software, reviews and programs for commercial vehicles.
