If you are talking about standard #2 diesel fuel oil and not motor oil and you have a #2 oil fired furnace or boiler in the home the answer is yes .
Drain some out..
Oil is too sticky and too thick, pump not functioning properly.
Friction produces heat. Oil lubricates the engine and reduces friction thus reducing heat.
The oil will make contact with the crankshaft. This will create a froth of oil mixed with air. This is a poor lubricant and will cause severe engine wear.
68 weight is the most common
it will over heat, and crack. palm oil is much too flammable to be inserted into a car engine.
Too much oil or a blockage in the return line.
You probably put an oil in with too thick of a visccosity.Engine has to work harder to turn crankshaft and move pistons, can cause a predetination.
When frying food, it is best not to try to get the oil hot too quickly. This can be a danger because if the oil heats too quickly, it can progress into a fire and spread very quickly. Always heat oil slowly when frying foods.
Olive oil holds heat better than vegetable oil. However, all types of cooking oils are susceptible to heat damage if they are left on a burner for too long.
The oil traps heat with is received through the sun. The heat that is trapped slowly curls up the leaves. As is the leaves were burned slowly. And the oxygen that it needs will be trap too.
Warm oil is runnier than cold oil. So either your bearings are worn, and the oil escapes too easy through the bigger-than-expected gap,or your oil pump is worn.
