The dreaded dry start phenomenon.
The least wear and tear on the machine is to keep it in a stable condition.
With the exception of some industrial machinery, automobiles, motorcycles, and other vehicles are usually controlled to vary their power output depending on the situation and to achieve their objectives.
The situation is far from stable.
Especially when starting up a machine that is cold, it is the time that wears out the life of the parts the most, and I am sure that many people would like to do something about it.
A dry start is when the engine has not been started for a while and oil has fallen from the cam heads, cylinders, and pistons and accumulated in the oil pan.
Most cylinder wear in internal combustion engines is due to dry starting.
Camshafts, crankshafts, and some turbochargers use journal bearings with soft metal rings to support the shafts, but there is also an aspect of fluid lubrication where oil in the bearings sprays out and floats the shaft.
It is easy for everyone to imagine that even if there is oil left, the lubrication environment is harsh until the oil pressure starts to build up and the shaft begins to float.
Even if there is oil left, the lubrication environment is harsh.
Ester oil is said to be effective for this purpose.
Ester oil is said to be chemically adsorbed on metals, adsorbing to pistons and cylinders and protecting them from dry-start damage.
However, esters are not the only components that are adsorbed.
Although engine oil contains a variety of anti-wear agents, esters alone are not sufficient to protect journal bearings during startup.
Temperament Lube recommends a solid lubricant

Because it is solid, it has excellent lubricity even at low temperatures and is fine enough to settle on metal surfaces and scratches, protecting them from dry-start wear.
