Places sales of motor oils

Engine oils are sold primarily at gas stations, but also for car washes and car showrooms and workshops. In all these places we can also get help in choosing the right motor oil. Some drivers also like to purchase a greater quantity of motor oils, for example, before going further in the route or just when you notice that some motor oil are sold at discount prices. Nowadays motor oils can also be ordered over the Internet, and then will be delivered to your home driver to the address indicated during the order process. This solution is used by drivers who spend a lot on the road.


Handwritten car repair - how to start?

More and more car owners decide to carry out servicing their own car, usually in his garage. Very often there arise garages genuine. Automotive for many people is in fact a true passion, and auto parts they are as well known as everyday objects. But if we lack knowledge in this field, you should reach for specialist guides, which are generally in the form of books. Often a lot of information in this area can be found on the Internet by typing in a search engine, for example, the model of our car. It all makes servicing cars is becoming easier and more and more people are opting for such a repair in your garage.


In the crankcase

In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings), and rods connecting the pistons to the crankshaft. The oil collects in an oil pan, or sump, at the bottom of the crankcase. In some small engines such as lawn mower engines, dippers on the bottoms of connecting rods dip into the oil at the bottom and splash it around the crankcase as needed to lubricate parts inside. In modern vehicle engines, the oil pump takes oil from the oil pan and sends it through the oil filter into oil galleries, from which the oil lubricates the main bearings holding the crankshaft up at the main journals and camshaft bearings operating the valves. In typical modern vehicles, oil pressure-fed from the oil galleries to the main bearings enters holes in the main journals of the crankshaft. From these holes in the main journals, the oil moves through passageways inside the crankshaft to exit holes in the rod journals to lubricate the rod bearings and connecting rods. Some simpler designs relied on these rapidly moving parts to splash and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. However, in modern designs, there are also passageways through the rods which carry oil from the rod bearings to the rod-piston connections and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. This oil film also serves as a seal between the piston rings and cylinder walls to separate the combustion chamber in the cylinder head from the crankcase. The oil then drips back down into the oil pan.45

Motor oil may also serve as a cooling agent. In some constructions oil is sprayed through a nozzle inside the crankcase onto the piston to provide cooling of specific parts that undergo high temperature strain. On the other hand, the thermal capacity of the oil pool has to be filled, i.e. the oil has to reach its designed temperature range before it can protect the engine under high load. This typically takes longer than heating the main cooling agent ? water or mixtures thereof ? up to its operating temperature. In order to inform the driver about the oil temperature, some older and most high performance or racing engines feature an oil thermometer.

Due to its high viscosity, motor oil is not always the preferred oil for certain applications. Some applications make use of lighter products such as WD-40, when a lighter oil is desired, or honing oil if the desired viscosity needs to be mid-range.6
