Why AMSOIL Synthetic Oil?
When it comes to deciding, what synthetic oil is right for your equipment we have went to the experts to get the synthetic oil basics. Watch the video below that explains the difference between conventional oil and synthetic oil and what sets AMSOIL apart from other synthetic motor oil.
The following list provides the various categories of oil and how the American Petroleum Institute (API) rates them.
Group I: Fractionally distilled petroleum that is further refined with a solvent extraction purpose to help with oxidation resistance and to remove wax.
Group II: Fractionally distilled base stocks then hydrocracked to further refine the purity.
Group III: Hydrocracked further than group II base stocks increasing the viscosity index higher with a lower wax content.
Group IV: Polyalphaolefins (PAO's). chemically engineered creating a true "synthetic oil base stock"
Group V: Base stocks that do not fall into group I-IV
When you add it all up Group 1 and II are typically considered mineral oils with Group II having an additional step of hydro cracking for added purity.
Group III: Considered synthetic oil by API in the USA but not in Germany and Japan. Why? Look back at the Group descriptions Group III base stock is the same as group II but hydrocracked or in plain English refined one-step further, thus it is still a mineral oil just further refined. Most of the synthetic oils sold in the US are actually Group III Synthetics oils.
On the other hand, AMSOIL Synthetic oil is pure Synthetic oil that falls into the Group IV classification. AMSOIL Synthetic oil uses a polyalphaolefins base stock, which is a single molecule not a hydrocarbon chain. Group IV base stocks are much purer that the other groups giving it superior mechanical properties over a very wide temperature range. Group IV Synthetic oils have a much-improved viscosity index and require little to no viscosity improvers, which are the most vulnerable to thermal and mechanical degradation over the life of the oil.
AMSOIL Synthetic oil is designed to reduce the wear and tear on mechanical components when compared to petroleum products while reducing oxidation and the formation of sludge, which is a killer in today's engines due to the heat buildup. As a result, AMSOIL Synthetic oil is engineered and warranted for up to 1 year or 25,000 miles in the majority of its motor oils in normal service applications.
Motor oil test comparisons continually prove the superior quality of AMSOIL synthetic motor oil.
So the answer to the question "why Synthetic oil?" is very simple, AMSOIL Synthetic oil is superior to petroleum motor oil, the independent tests prove the facts.
One last point, many people refer to AMSOIL as AMZOIL or AMS OIL, actually AMSOIL started out as AMZOIL but changed the name due to a name dispute way back when it first came to market. Although when you say it is sounds like AMZOIL is actually AMSOIL.
