Are synthetic oils better than conventional motor oils ?
Synthetic oils are man made lubricants which were originally created for jet aircraft engines. They have a wide range of performance and can protect the engine at very high oil temperature conditions. In other words , they have exceptional thermal stability. Where conventional oils would turn to jelly at very low temperatures and could break down at very high temperature , synthetic lubricants manage to remain fluid at these temperatures and give adequate lubrication where it is needed most.
In most cases the answer is “yes”. Synthetic oils are man made lubricants which were originally created for jet aircraft engines. They have a wide range of performance and can protect engine at very high and very oil temperature conditions. In other words, they have exceptional thermal stability. The main disadvantage of synthetic lubricants is that they are inherently more expensive than mineral oils. This restricts their use to speciality oils and greases which command premium prices.
