Are Cheap Auto Motor Oils Worth It

Motor oil is stored generally in an oil pan, below the crankshaft on the underside of the engine. 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. This is essential, because the engine must have motor oil - 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. Oil normally thins out, as it is heated, but it is also possible by using additives or because of natural inherent qualities. An oil with the viscosity of 10 at zero degrees F (10W30) might also be able to pass the thickness test for even 30,40, 50 or 60 viscosity oil at 210 degrees Fahrenheit. This characteristic is called multi-viscosity. Turbocharged engines may well benefit greatly from the use of synthetics because of the improved temperature and high range heat resistance but for the average motorist, synthetics may not be worth the higher outlay, especially if the vehicle is older, high mileage and leaks or burns oil. 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. Yet if there is one message from experienced auto mechanics and technicians it is to change your oil often and early - especially if are in extreme conditions such as commercial taxi or police use or drive in a very cold climate in the winter time.
