Synthetic Oils Beat Petroleum Oils On All Counts!

Oil is the lifeblood of your vehicle's engine. Without it, there is little likelihood that any of your vehicles would make it past the end of our street each morning. For decades conventional petroleum oils have been providing adequate protection for all of our vehicles. Notice the key word here: adequate. Petroleum oils, for the most part, have done an adequate job of protecting our engines from break down. If you change it often enough, you can be relatively sure that your car will last 100,000 to 150,000 miles without a serious engine problem.
My question is this: Why are you settling for adequate when something better has been available for the past 25 years? Do you ask your mechanic to simply keep your vehicle from breaking down, or do you want him/her to keep it running in tip-top shape? The fact that you are reading this article suggests the latter. It is perfectly reasonable to expect top performance from your vehicles. You are certainly paying for it. It's tough to buy a vehicle for less than $15,000 to $20,000 anymore. That's a great deal of money to shell out for adequate performance.
Today's engines are built for better performance, and, although petroleum
oils are designed for better performance today than they were 10 or 20 years
ago, there is only so much that can be done. Today's engines need high
performance lubricants, and synthetics are the only ones that fit the bill.
When thermal or oxidative break down of petroleum oil occurs, it leaves
engine components coated with varnish, deposits and sludge. In addition, the
lubricant which is left is thick, hard to pump and maintains little heat
There is another effect of the non-uniformity of petroleum oil molecules
which reduces their effectiveness as well. Uniformly smooth molecules slip over
one another with relative ease. This is not the case with molecules of differing
size. It would be much like putting one layer of marbles on top of another. If
the marbles were all of the same size, they would move over one another fairly
easily. However, if they were all of differing sizes, the result would be much
less efficient. In the case of petroleum oils this inefficiency leads,
ironically, to added friction in the system (the very thing that lubricants are
supposed to reduce). Hence, petroleum oils are only marginally capable of
controlling heat in your engine.
So, if you like the hassle of changing your oil regularly and you are only looking for marginal performance for the next 100,000 miles, feel free to use petroleum oils. By the way, if you're interested, I've got an old dishwasher for sale too. You have to rinse your dishes first, it's really loud and runs for about 3 hours, but it gets most of the food off of our plates. It's a steal at only $50. Let me know if you're interested.
However, if you aren't all that fond of pulling dirty dishes out of your
dishwasher, I'm going to assume that you don't relish the idea of changing your
oil every 3,000 miles or dealing with another pushy car salesman every 3 to 5
years either. If that's true, keep reading. I think you're going to like this.
Synthetic lubricant molecules are pure and of uniform size. This is because
synthetic oils are designed from the ground up with the sole purpose of
protecting your engine. Nothing is added if it does not significantly contribute
to the lubricating ability of the oil. In addition, in top-quality synthetics,
no component is added which is contaminated with any substance that might lessen
the lubricating qualities of the oil. Not only that, synthetic oils are designed
so that the molecules are of uniform size and weight. This significantly adds to
the lubricating qualities of the oil.
Moreover, because of their uniform molecular structure, synthetic lubricants operate with less friction than petroleum oils which have the non-uniform molecular structure discussed earlier. The result is better heat control, and less heat means less stress to the lubricant. Thus, synthetic oils can be used safely for much longer drain intervals than conventional lubricants. In fact, AMSOIL synthetic oils have been guaranteed for 25,000 miles or one year since 1972. Red Line Oil also recommends long drain intervals of 10,000 to 18,000 miles.
You might ask why other synthetic oil manufacturers are not recommending extended oil drains for their synthetics. The answer is really very simple: money. They are afraid that if they recommend longer drain intervals, they won't sell enough oil - petroleum oil, that is.
You see, petroleum oil is their golden goose, and has been for years. The only reason large oil companies produce a synthetic oil is because somebody else did it first (AMSOIL), and they must please the small (but growing) percentage of the population which has already decided that synthetics are better and won't purchase anything else.
Petroleum oil is where the money is. With recommended oil drains of only
3,000 miles, many people are changing their oil 5 to 8 times per year. If
everyone suddenly switched over to synthetics, they would begin to realize that
it is possible to go 10,000 to 25,000 miles or more without an oil change
(depending upon the oil). This is a scary thought for large oil companies who
depend upon regular oil changes for their business.
In addition, because of their uniform molecular structure, synthetic oils do not cause the "blanket effect" which was mentioned earlier. Since each molecule in a synthetic oil is of uniform size, each is equally likely to touch a component surface at any given time, thus moving a certain amount of heat into the oil stream and away from the component. This makes synthetic oils far superior heat transfer agents than conventional petroleum oils.
ENGINE DEPOSIT REDUCTION
COLD TEMPERATURE FLUIDITY
The uniform molecular structure of synthetic oils has another performance
enhancing benefit as well. In a petroleum oil, lighter molecules tend to boil
off easily, leaving behind much heavier molecules which are difficult to pump.
Certainly, the engine looses more energy pumping these heavy molecules than if
it were pumping lighter ones. Since synthetic oils have more uniform molecules,
fewer of these molecules tend to boil off. Moreover, when they do, the molecules
which are left are of the same size and pumpability is not affected. Obviously,
the end result is little loss of fuel economy or performance.
In 1989, Mechanical Engineering Transactions had this to say in its
1989 Synthetic versus Mineral Fluids in Lubrication article: "Oil drain
intervals in both industrial and automotive applications can be extended
typically by a factor of four due to the improved oxidative stability of
appropriately additized synthetics."
If these benefits are of importance to you, don't settle for adequate anymore. Step up to the ultimate in protection, synthetics. Better yet, don't just use a synthetic, use the synthetic manufactured by the largest, most experienced synthetic lubrication company in the world: AMSOIL. AMSOIL beats every other synthetic on the market in terms of engine protection, fuel economy and extended drains.
AMSOIL has been recommending 25,000 mile oil drains for 25 years without one mechanical breakdown due to these practices. Name one other oil company that has the guts to subject their oil to that kind of abuse and guarantee it with a written warranty. There aren't any because there is not one other oil company out there that can match AMSOIL's commitment to a quality product or their integrity to stand behind that product.
