What do the grades of oil mean?
The Society of Automotive Engineers (SAE) developed a scale for both engine (motor oil grades) and transmission oils. This number represents the oil’s resistance to thinning at high temperatures. For example, 10W-30 oil will thin out at higher temperatures faster than 10W-40 will.
What are the different grades of motor oil?
Motor oil can be segmented into four basic varieties—synthetic oil, synthetic blends, high mileage oil, and conventional oil.
Is 5w30 oil thicker than 10w30?
10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.
Is 20W50 good for high mileage?
The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. The thickness is not meant for daily, older vehicle use.

What is the best motor oil for generators?
The Honda 10W-30 motor oil is conventional synthetic oil that is suitable to increase the longevity of the generator. The oil is ideal for reducing the consumption and the formation of any residue. The oil is stronger than other oil brands and retains viscosity.
What is the best engine oil temperature?
Your engine functions at its best when the oil is between 180 and 200 degrees. Most factory cooling systems, however, maintain fluid temperatures of approximately 200 to 220 degrees, which means the maximum temperature drop it can create in your oil still exceeds the ideal temperature.
Which diesel engine oil should I use?
Function. Oil is used to lubricate the pistons as these are pushed into the combustion chamber and return downward to the crankcase.
