Automotive Motor Oil Change Frequency

Believe it or not your vehicle is made up of thousands and thousands of parts the majority of which are metal in origin and composition. It is a known fact in the work of mechanics that metal rubbing against raw metal creates great friction, and wear and tear on the metal surfaces in collision with each other. Thus without adequate lubrication from oil type lubricants you’re the motor in your vehicle – be it car, truck or S.U.V. would not last long and would thus have a very short life span.

There are some partly or wholly non-petroleum oils which are referred to as “synthetic oils”. According to manufacturers of these synthetic oils , a car or truck can be driven up to 30,000 miles ( 50,000 km) without the requirement or need for an oil change. The most grueling auto racers use premium synthetic oils almost exclusively. All sorts of claims have been made for synthetics which after all were developed for tank use on the Russian front in WW2. The most vital and important claims reduced friction , reduced wear, improved fuel economies , and extended oil change interval times. While no motor oil will eliminate engine wear, synthetics do offer measurable improvements in engine life according to Alberta based auto industry analyst M. L. Labovitch. How much of course is of course still subject to tremendous and ongoing heated debate and debates. In terms of flow characteristics most synthetics flow like water at – 40 degrees Celsius below zero , a temperature point where most conventional motor oils and even Russian vodka freezes solid. If it happens ( as it sometimes does in case of limited or no routine auto maintenance and service) that the oil filter itself is so dirty that motor oil cannot pass through the oil filter, in most cases a bypass valve will open and the motor oil goes directly to the moving parts. There are some partly or wholly non-petroleum oils which are referred to as “synthetic oils”. According to manufacturers of these synthetic oils , a car or truck can be driven up to 30,000 miles ( 50,000 km) without the requirement or need for an oil change. The most grueling auto racers use premium synthetic oils almost exclusively. What are the drawbacks of synthetics ? Price is the primary concern with synthetics costing from three to five times as much as conventional motor oils and lubricants. But just considering the increased length of time between oil change intervals they provide, the real cost difference may not be all that great by any means or manner of form. Some people just must have top of the line – the very best lubricant money can buy – even dirty un-cleaned motor oil if necessary. It seems that half a loaf of bread is better than no bread at all, or in this essential though lubrication provide by dirty, as opposed to more pure, lubricating fluids.

The oil drain plug is in the oil pan at the the bottom of the engine. This has to be removed with a solid wrench or socket. If you do the work yourself as you remove the plug, be careful not to let hot oil drip onto your hand or arm. It usually and generally goes through the camshaft, up to lubricate the valve lifters and rocker arms, then down to the crankshaft, the pistons and down the inside interior walls of the engine’s cylinders. Gravity brings the motor oil eventually to the oil, where the process begins again. In this way, the motor-oil lubricates all engine parts, cooling the surface and surfaces and reducing wear. In addition the motor oil and oils also act as a liquid washer and sealant around the pistons. Motor lubricating oil serves to seal the area on the circumference of the pistons. This way none of the air/ fuel mixture that is compressed for the combustion purposes, – to drive your motor and power plant, can escape. As a result the lubricating oil acts in addition to simple lubricant benefits to increase engine power and horsepower and maintains a far more powerful and efficient power plant that would be available otherwise.

Most motorists take their engine oil for granted. Multiviscosity is a most highly desirable characteristic in an auto engine motor oil and lubricant. If the oil is relatively thin at low temperatures, it will flow easily overall and provide good lubrication. This is especially important in the cold northern Alberta winter time climate. From the time the engine starts in the minus 40 degree temperature and the engine oil begins to flow more engine wear and tear occur than in thousands and thousands of normal driving in warmer more moderate ambient temperatures. Current auto industry recommendations and protocol in 2010 is to start the vehicle and bring the temperature up to its normal operating temperature. The motorist can do this simply by letting the engine run for 10 to 20 minutes . Take care not to run the car in an enclosed space, underground garage or a garage with the large door ways closed. Dangerous fumes and carbon monoxide poisoning can result.
In one tragic terrible case a home owner left the auto running in an attached garage. The CO fumes entered the home poisoning his family – especially if are in extreme conditions such as commercial taxi or police use or drive in a very cold climate in the winter time.

Three Automotive Services Every Car Needs

Taking care of your car could take up a lot of time. Car fanatics could argue that its all part of the pleasure in owning a car. On the other hand, other will say its something that needs to be done just to keep the car running. The bottom line is both car owners are delighted with the idea of an auto service garage that offers all the automotive services a vehicle needs.

A master mechanic knows just what a car needs and at the same time has the automotive services to fulfill it. In other words, a good auto service garage doesnt cater to a specific kind of vehicle. The more automotive services it can offer the better. That means customers dont have to hop from one garage to the other. At the same time, the mechanics can completely own up to what they have started with.

Several automotive services any car repair shop should have are the following:

Tune Ups

Cars need maintenance services. That means the engine needs to be checked on regular intervals to make sure that it is in perfect condition. Advancements in tune up services are ideal because vehicles are also affected by technological developments. If your car is one of the newest models, a proper tune up involves a diagnostic scanning of your its onboard computer systems. This could be one of the most costly automotive services your car can experience. But if your car is the expensive type, its just logical to give it the treatment it needs including skills from the expert mechanic.

Transmission

Another of those most common automotive services your car needs is transmission. Most cars nowadays use fuel injections which could be really complicated for the unskilled mechanic. Transmission replaces about 25% of the contaminated fluid, leaving behind 75% of the old fluid to mix with the new. This sounds simple, but the latest technology is required to make it right.

Timing belts replacement

Car owners should know that timing belts should not remain permanent on a car. In the past, chains were used instead of belts but that produced too much noise so the belts were introduced. Belts are not really costly, but it takes experience to be able to replace them correctly. If you do not avail of this specific service, your engine could get seriously damaged.

Top 12 Automotive Wiring Tips

The best connection is a properly done solder joint. If you aren’t sure how to solder, crimp the connection then solder it. Cold solder joints not only introduce resistance, but they can come apart.

2) Keep your grounds as short as possible. It is far better to have a few more connections than a long ground that can build heat and introduce ground loops. It is common practice to run a ground wire from a high demand devise such as a fuel pump back to the battery. This not only adds additional loads to the pump or devise but also can lead to device failure. Have you ever seen a production auto with a ground cable longer than the positive cable?

3) If at all possible, use stainless hardware to fasten all primary cables. Some galvanic or plated hardware can cause dissimilar corrosion and can sometimes carry more impedance that its stainless counter parts. On smaller secondary circuits, this is not as important.

4) Battery storage. Keep batteries away from humidity. Keeping it charged will prolong its life. If a battery is dead, cool it before you charge it. Put in the refrigerator or outside if its cold. Cool batteries charge better.

5) Batteries specifications and charge rates are for 77 degrees Fahrenheit. Temperature variations will change charge rates.

6) Use relays. Anytime you want to switch a device that draws more current than is provided by an output of a switch or component you’ll need to use a relay. The coil of an SPDT relay that we most commonly use draws very little current (less than 200 milliamps) and the amount of current that you can pass through a relay’s common, normally closed, and normally open contacts will handle up to 30 or 40 amps. This allows you to switch devices such as headlights, parking lights, horns, etc., with low amperage outputs such as those found on keyless entry and alarm systems, and other components. In some cases you may need to switch multiple things at the same time using one output. A single output connected to multiple relays will allow you to open continuity and/or close continuity simultaneously on multiple wires.

7) Most electromechanical devises are rated according to the MTBF (Mean Time Between Failures). You improve your odds of a long MTBF by keeping your electrical devices in a low humidity, low heat environment.

8) Do not ever use THHN/THWN wire. This wire (insulation) classification is not rated for automotive use. Cars move and vibrate which chafes the insulating material.

9) A wire that is rated for A/C voltage may have a different rating when used in low voltage D/C applications. Your house uses A/C, your car uses D/C.

10) The best primary power cable is a type TEW or MTW (Machine Tool Wire) as its rated for continuous use with higher amperage loads.

11) OFC (oxygen free copper) is by far the best cable for automotive use. However, it is expensive and requires a quality crimper and should be soldered for security. The most common application for this wire is high-end car stereo applications.

12) If you are like me, you may choose to skip OFC and go with TXL wire. TXL (thermal cross-linked) wire is next best. TXL wire has twice the voltage rating of standard GPT (general purpose) wire. Most high-end harnesses are made with this wire. If you want to keep your ride for the long haul, you may want to pony up for a harness made with this wire.
