What does viscosity of motor oil?
hi brooklyn, the viscosity of motor oil is how quickly it flows
How is the knowledge of vicosity is applied to motor mechanic?
Motor oil moves through the engine system and its components to lubricate them and pick up contaminants that can harm the engine. ... Oil is measured by its viscosity, or how thick or thin the oil is. An example of a difference in viscosity is comparing honey and vinegar. Honey is thick and flows very slowly when poured.
Motor oil is used to lubricate different parts of an engine The viscosity of oil changes as a motor runs or is turned off What external factor will most frequently change the viscosity of the motor?
decreased temperature
Cause of engine oil turning black?
engine oil turns black when oil mixes with the carbon from normal combustion inside the engine. this process eventually changes the viscosity of the oil and keeps it from flowing through and lubricating the motor properly.
Can you mix different weights of motor oil?
Of course you can but when you do you are changing the viscosity of the oil. Your engine requires a certain weight or viscosity of oil. Use only the weight oil recommended by the manufacture.
What does a motor mechanic need to know about viscosity?
A mechanic needs to know which oil to select for the various moving parts of a car. The oil you use in the gear box is usually a higher viscosity than the oil used in the engine. The engine uses different viscosity oils depending on the seasonal temperature.
How do you Engine Oil?
Well Engine oil manufacturers keep the manufacturing techniques secrets with each others. Most motor oils are made from a heavier, thicker petroleum hydrocarbon base stock derived from crude oil, with additives to improve certain properties. The bulk of a typical motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule. One of the most important properties of motor oil in maintaining a lubricating film between moving parts is its viscosity. The viscosity of a liquid can be thought of as its "thickness" or a measure of its resistance to flow. The viscosity must be high enough to maintain a lubricating film, but low enough that the oil can flow around the engine parts under all conditions. The viscosity index is a measure of how much the oil's viscosity changes as temperature changes. A higher viscosity index indicates the viscosity changes less with temperature than a lower viscosity index.

Why low viscosity motor oil used in the winter and high viscosity motor oil used in the summer?
Low viscosity oil flows easier when it is cold but become thinner when it is hot.
Can you mix motor oil viscosities?
Short Answer is Yes but don't mix brands Long answers From the Chevron.com site: "Can I mix different viscosity grades of motor oils?" "Yes. It is always advisable to not mix motor oil brands, however, different viscosity grades of the same brand motor oil are compatible. Be aware that mixing viscosity grades will turn out a product that is different in viscosity than either what was originally in the engine or what was added." From Shell.ca: "If you mix viscosity grades such as a 5W30 low-viscosity oil and a 10W40 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 5W30, but thinner than the 10W40. This change does not reflect incompatibility - it's simply a re-balancing of the viscosity characteristics. In all other ways, the product should work as expected. But there's absolutely no danger about incompatibility resulting from mixing engine oils," Miller says. "We've tested all of our grades and brands, and we haven't observed any problems." From Mobil1.com: "For our customers to choose a viscosity grade, we recommend they follow the engine manufacturer's recommendations as indicated in their owner's manual. There is no need to mix two Mobil 1 viscosity grades when one will do; however, we see no problem mixing different SAE grades of Mobil 1 Tri-Synthetic series motor oils."
What is the cranking amps drawn from the starter motor of a 200 tdi engine?
Depends on a lot of factors, including oil viscosity, engine mileage, temperature, etc. The best way to find out is to hook an ammeter to your starter motor wire, you will get an exact answer.
What happens if you use the wrong weight motor oil in a vehicle?
If you use the wrong weight motor oil in an engine, it is possible that you could destroy the engine due to lack of lubrication, either because the oil's viscosity is to low to provide adequate bearing separation, or because the oil's viscosity is to high to permit adequate lubrication. Use the manufacturer's recommended oil.
