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.
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 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.
it will over heat, and crack. palm oil is much too flammable to be inserted into a car engine.
68 weight is the most common
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.
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.
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.
You need three things to have a fire: heat, fuel, oxygen All oils are fuel, oxygen in the air, too much heat on the stove...poof! At a lesser heat, or shorter time, oil can do a 'slow burn' which is what happens when a pan with oil that is forgotten too long on the stovetop. To some degree, that is also why the oil in an engine breaks down and has to be replaced periodically.
