Engine oil doesn't have polarity.
haha so which one of you chilldress ipc people asked this one haha
there is none
conclusion on oil
A false analogy is where an invalid conclusion is drawn from a comparison between two apparently similar situations. eg Water is liquid and is good for you to drink. Engine oil is also liquid and must therefore be good to drink. Just because water and engine oil are analogous (similar) in one respect does not mean they are analogous in another. This is a false, and in this case highly dangerous, analogy.
The property responsible for the fact that water and oil do not mix is their difference in polarity. Water is a polar molecule, with positive and negative ends, while oil is nonpolar. As a result, water molecules are attracted to each other and repelled by oil molecules, making them immiscible.
Engine oil entering through the breather hose can indicate a problem with the engine's internal pressure regulation, often due to excessive blow-by from worn piston rings or valve seals. This condition can lead to oil being pushed into the crankcase ventilation system, potentially causing oil to be drawn into the intake system. It may result in decreased engine performance, increased emissions, and oil contamination. Regular maintenance and monitoring can help identify and address such issues before they lead to more significant engine damage.
On a 2stroke engine the oil/gas mixture enters the crank case (lubricating the crankshaft bearings) before it is drawn into the cylinder.
Water molecules have a higher electric polarity than oil.
On 3.7-liter engines, the oil groove on the connecting rods typically faces the crankshaft. This orientation ensures proper oil flow for lubrication, allowing oil to be drawn from the crankshaft and distributed to the connecting rod bearings during engine operation. Always consult the specific engine manual for precise installation guidelines.
Oil does not mix with water or other polar liquids because oil is nonpolar, while water and other polar liquids are polar. The difference in polarity creates a strong intermolecular force between the molecules of oil and the molecules of water, preventing them from mixing. This difference in polarity results in oil forming a separate layer on top of water.
Crankcase oil is engine oil , so yes
Oil is low in polarity primarily due to its hydrocarbon structure, which consists of long chains of carbon and hydrogen atoms. These molecules have nonpolar covalent bonds, resulting in an overall nonpolar character. As a result, oils do not readily interact with polar substances, such as water, making them hydrophobic. This low polarity is a key factor in oil's ability to serve as a nonpolar solvent and to dissolve other nonpolar compounds.
