The best kind of synthetic oil usually uses a combination of three various synthetic base fluids that includes polyalphaolefin (PAO) as well as alkylated aromatics. Whatever the kind of chemical makeup, synthetic actually have similarities. Compared to conventional oils that have molecules of different sizes, a molecular structure of synthetics in fact are consistent when it comes to shape and mass. Such uniformity simply means that the molecules will create less friction when it collides and when there’s less friction, which means less heat.
Synthetic oil have uniform properties than any conventional mineral lubricant oil. A conventional motor oil in fact is made from Group I and II base oil stocks which are blended together with additives. The oil likewise have hydrocarbon molecules which comes with variation in length. There are light liquids and there are also heavy ones. This then will contribute to chances of conventional mineral oils in solidifying in cold weather and to also evaporate if it is hot. The oils likewise have residual molecular compounds of which detract from the lubricating properties and then contributes to the sludge in engines. This is the reason why conventional mineral oil change are necessary.
There are also synthetic motor oils which are made from Group III and IV base oil stocks which comes with uniform size hydrocarbon molecules and none of such contaminants are found in Group I and II base oils. Its uniformity leads to excellent performance, even with the low and high temperature performance.
Why Synthetic Oil is Better
Flows Easier in Cold Weather
Because it can flow easier in cold weather, there’s no loss of prime when the oil is cold. This is likewise resistant to viscosity breakdown due to friction, heat and chemical contaminants.
Oil Change is Lower
Changing the oils in synthetic oil is actually lower compared to regular oil change. There are in fact much longer change intervals for synthetic oils which is 7,500 to 10,000 miles on the oil changes than 3,000 on mineral oil.
Another thing is that synthetic oil change intervals are usually said to be up to 25k miles between changes. It is however best to avoid doing it that long.
Keeps the Engine Clean
As the oil will circulate through the engine, this could pick up some deposits. This then causes conventional oils to form sludge that could reduce the efficiency of your engine and will also reduce the life of your engine. The full synthetic oils have fewer impurities than the conventional and synthetic blend oils and this can in fact resist formation of sludge and deposits in the engine.
You may have understood already why synthetic oil is a lot better. Synthetic oil costs on its change is however twice as much compared to the conventional oil. But, it is able to last longer, so your actual cost increase would be close to about 50 – 60%. If you switch towards synthetic oil, you will find that it is more expensive, but it has higher returns on investment in the long run.
