Petroleum vs Synthetic
With petroleum oil in the engine 88% of the internal contamination comes from the oil. This is because of the chemical reactions within the engine's crankcase between petroleum oil and various by-products of combustion, including sulfur, heat and water. It is not the by-products themselves that make the oil dirty. It is the chemical reactions caused by the by-products.
AMSOIL is not susceptible to these chemical reactions in the crankcase. To understand this, we must look at the differences in molecular structure of petroleum and AMSOIL.
Petroleum is a hydrocarbon. AMSOIL is a diester formed by combining fatty acids with isopropyl alcohol in a five million dollar synthesis machine. AMSOIL is 100% saturated. This means that it is made up entirely of tightly bonded molecules that are extremely difficult to break apart.
Petroleum oils are less than 55% saturated, often less than 50%. This means that almost half of every quart of oil you put in your engine is unsaturated, or loosely bonded molecules of hydrocarbons. It is not the saturated part of petroleum that causes difficulties, it is the half that's unsaturated.
There are several damaging chemical reactions that are constantly happening to the unsaturated or loosely bonded hydrocarbons. Some of the more serious are:
AMSOIL's high surface tension (higher than water) causes it to cling to metal and to sheath tiny particles of water into a glove of AMSOIL until the temperature of the water rises above 212 degrees Fahrenheit. Then 100% of the water evaporates preventing any moisture build-up in the motor or drive train. Condensation can therefore, be easily tolerated with AMSOIL.
AMSOIL has extremely high film strength. Film strength refers to the amount of pressure it takes to squeeze the lubricant out from between two flat pieces of steel. Petroleum oil ranges from 250-550 psi. AMSOIL's film strength is over 3250 psi.
Therefore, the entire inside of the engine "floats" on a film of Amsoil. This is the reason for the average increase in gas mileage of 12% and 6% boost in horsepower that users are experiencing.
AMSOIL is by nature a high detergent lubricant. It has been specifically formulated for high detergency without using detergent additives that quickly break down and wear out. This is possible because of the chemical makeup of AMSOIL.
As a result, AMSOIL has the ability to remove tar, sludge, varnish and other deposits from the inside of the crankcase, leaving wear surfaces mirror clean.
Gum and varnish are the causes of the following problems in engines:
AMSOIL's extremely high detergency means that it is capable of reducing and/or eliminating the above problems.
AMSOIL has a very high seal compatibility. Petroleum oil shrinks cork gaskets and requires a "swelling agent" additive to prevent this or limit its effect. AMSOIL has the ability to restore petroleum-oil- hardened neoprene and rubber seals to their original resiliency. AMSOIL does not shrink cork gaskets.
AMSOIL Gives You The Luxury Of Changing Your Oil Once A Year...Or Every 25,000 Miles!
Why 25,000 miles? In laboratory tests...the first signs of non-exterior contaminants show up sometime after 30,000 miles. 25,000 miles is therefore a conservative figure. Samples of oil can be sent to any oil testing laboratory for analysis (AMSOIL has a kit available for that, Analysis Kit#G-1451) should a user feel uneasy about extended service.
Amsoil gives your vehicle a new lease on life!!!
One thing is certain, when motorists switch to AMSOIL synthetic motor oil their engines are being treated to the best synthetic oil money can buy. And while some engines appear to take the change in stride and continue operating the same as ever, others seem transformed. What may new AMSOIL users experience?
Oil pressure moderates - At idle, a slight oil pressure drop indicates the new oil flows more freely than the old oil did and that's beneficial to the engine. High oil pressure at idle indicates the oil pump must work hard to push the oil through the engine, which is stressful for the pump. Hard to pump oil may also leave some components under lubricated and unprotected.
If they keep an eye on their oil pressure, new AMSOIL users will find it's steady as she goes at the new, better pressure.
Higher engine rpms - because AMSOIL synthetic motor oil generates less intra fluid friction than conventional oils do and do a better job during boundary lubrication conditions, engine bearings rotate more easily with AMSOIL in the engine. You get more bang for your fuel buck. For a given amount of energy, a bearing that moves easily rotates faster than one that doesn't move freely.
Increased fuel efficiency - Less intra fluid friction and smoother boundary lubrication translates into fuel savings as less energy is used to overcome the friction required to move the vehicle a given distance.
More power - Yet another side to lower intra fluid friction and better boundary lubrication. The power the engine used to overcome both with conventional oil now goes to moving the vehicle. Many users report their shift points actually decreases due to the "extra" power their engines find with AMSOIL.
"Spring" cleaning - Synthetic oils clean as they go, removing sludge and deposits left by the previous oil. If AMSOIL synthetic motor oil is installed in a particularly fouled engine without an AMSOIL Engine Flush pretreatment, sludge and debris, freed by the cleaning action of AMSOIL, ends up in the oil filter. Motorists should change their filters frequently until the cleaning process ends. Oil consumption will increase if full filters are not changed. Once completed, the vehicle's oil consumption rate will return to normal or even to a rate lower than its customary rate.
Of course, AMSOIL synthetic motor oils actually help engines achieve extremely low oil consumption rates, due to the oils extremely low volatility.
Easier cold starting - Less prone to low temperature gelling, AMSOIL synthetic motor oils allow engines to turn over more easily in colder temperatures than conventional oils do. In fact, most AMSOIL users find they no longer need block heaters.
Lower operating temperature - Oil sump temperatures may run as much as 20º F cooler with AMSOIL than they do with conventional oils. Friction generates heat, and since AMSOIL synthetic motor oils generate less intra fluid friction than other oils do, they also generate less heat.
Additionally, AMSOIL synthetic motor oils are better heat transfer agents than conventional oils are, so the engine's total heat "bill" adds up to less with synthetics. Flexible synthetic lubricant molecules allow heat to swirl away from hot surfaces and into the midst of the oil stream. (It's called "turbulent flow.") Rigid conventional oil molecules move heat along the hot surface. The surface of the oil film gets overburdened with heat while the core of the oil stream gets a free ride. (It's called "laminar flow.") Plus, the carbon deposits formed as conventional oils break down coat and insulate hot surfaces.
