There are basically hundreds of types of synthetic lubricants and moisturizers and hundreds more different versions of these! All custom customised for specific uses from automotive to industrial to help aviation. Here I will cover the most common synthetic lubricants intended for automotive, fleet and some manufacturing uses and how they get along with the petroleum oils the majority of individuals are familiar with.
The components of a man-made lubricant base stock usually are man-made designer molecules “synthesized” by chemically reacting some simple compounds two cause a finished base stock. This gives a lubrication engineer the capability to tailor the base stock into a specific application for highest lubricant performance.
To understand just how synthetic lubricants relate to all of us marketplace we must we tell you the list of available oils. Inside the “oil bidness” different skin oils are categorized in groups of the chosen type of base stock these are made from. The base stock is merely that. The bulk of the product the thing is in the bottle minus the chemicals that are mixed in to make the necessary oil perform certain functions.
Group 1 oil:
These are the old large paraffin base oils. They may not be used for modern engine essential oils anymore but can still possibly be found in those little remover bottles of all-purpose household acrylic you buy at the hardware store to get stuff like oiling door pivots.
Group two oils:
This can be a standard petroleum base investment that all modern conventional oil oils are made from. Quality ranges widely depending on where it turned out “dug up from”. During “finished” form it can incorporate various amounts of paraffin (wax), impurities left over from improvement and from the ground it originated in! Chemically it is a hodge podge of different sized hydrocarbon substances, not all of which “get in addition to each other” so to speak. The effect of this is a product that creates sludge, varnish and physical wear as it ages and also breaks down in service.
These skin oils have steadily increased over the years as API providers requirements have gotten stricter. However as modern machines pump more horsepower coming from smaller engines with fewer total oil sump potential and the level of horsepower/torque carried though today’s light weight gas efficient drive trains remain climb, lubricant manufacturers realize that conventional petroleum oils actually just cannot be improved virtually any farther.
Hence the proceed we see by automakers to help synthetic fluids; both in search engines and transmission/differentials. Combining this with the need to improve gas consumption and synthetic lubricants very well know the ability to do just that and see why “factory filled” having synthetic is becoming more and more widespread.
Group three oils:
Set three oils are oil oils that have been hydroisomerized, “hydro-cracked” as it is commonly called. Essentially the most stringent level of petroleum acrylic refining. Much of the paraffin in addition to impurities have been removed and it is performance on any number of marketplace tests is substantially greater than its group two friends.
Although it is not made from a produced, engineered molecule and as such is just not a true synthetic oil, it will offer a portion of the benefits you should expect from a true man-made and in fact is usually marketed and marketed as a fully synthetic product.
In fact, the majority of synthetic oils on the market are in reality made from group three skin oils because of a lawsuit a few years before between Mobil and Castrol that totally changed the particular synthetic oil industry. For this reason lawsuit, the buying community has largely been bamboozled into believing that these essential oils are actually real synthetic.
Car headlights happened. Exxon- Mobil Inc. makers of Mobil One sued Castrol, makers of Castrol Syntec, accusing them of marketing a new hydro cracked petroleum acrylic as a synthetic-which they were! Mobil Inc. felt that Castrol Inc. had pursued an unfair market advantage mainly because group three based essential oils are much less expensive to create than true synthetic essential oils yet Castrol was advertising and marketing Syntec as a 100% man-made product:
Castrol could make the item for less, and sell it for less in addition to un-fairly under the cut just about all its competitors in the man-made oil market with a necessary oil that was not truly a man-made product. In the end, though, Castrol convinced the court that will group a three-based necessary oil has been sufficiently refined which it should be able to be marketed in addition to true synthetic oils. This is the court expanded the definition regarding synthetic to include a group of three based oils. Because the man-made oil market is the most effective growing part of the lubricants market, manufacturers are eager to bounce up and grab the income that having that sexy purchaser grabbing word synthetic for the bottle brings.
Group several oils have nowhere at the performance of true personalized engineered synthetic oils, specifically in temperature extremes where the adult males get separated from the children so to speak!
Group four essential oils:
Polyalphaolefln and related olefin oligomers and olefin polymers. (Synthetic hydrocarbon) PAO because they are commonly called are an accurate man-made engineered base acrylic produced by a catalytic reaction with different alpha-olefin compounds. PAOs are widely recognized as giving an outstanding performance for many lube applications because of their very high viscosity index, a wide operational heat range and because it is heat and shear stability.
PAOs also have low corrosivity and therefore are compatible with mineral oils as well as the range of materials that machines and other machinery are constructed from.
The molecular structure of PAO’s are easily customized for proper use in all kinds of applications from automotive to industrial and they are widely used in motor natural oils, gear lubes, high temperature/extreme pressure greases, Compressor natural oils and hydraulic fluids.
Team five oils:
This team comprises all synthetic natural oils other than PAOs. A short listing includes Esters such as Polyolesters (Neopentyl Polyol esters, Diesters (Dibasic acid esters) Various Alkylated Aromatics, PAG (poly Glycol/various Glycol’s), Silicones etc. This particular group of synthetics is mainly used for various industrial as well as aviation applications. Polyol esters are commonly used for turbine and aviators applications.
They are very thermally stable and ideally best for very high-temperature use. Therefore their use in such things as higher temp greases, jet applications and gas turbines. There is a very low coefficient of chaffing and are sometimes added throughout small amounts to mineral natural skin oils and other synthetic oils in order to reduce the coefficient of chaffing of the finished product. Diesters are most commonly used in aviation along with industrial compressor applications on the other hand because of the tremendous anti-scuffing security they offer. They are often added throughout small amounts to PAO structured two-cycle oils as this element is very beneficial to a two-cycle motor oil.
Diesters are shear-stable, have good lubricity, and detergency and are polar this means they have an electrical charge that produces them to cling to metal surfaces-a desirable trait for most moisturizers. Diesters are not compatible with most seal materials as they might cause excess swelling of many popular seal materials. Because of this, they are generally added in small amounts for you to automotive PAO based natural skin oils to provide a positive seal purpose.
