There is always a lot of debate regarding Synthetic vs. Non-Synthetic, Brand "X" vs. Brand "Y", Etc. I am not here to debate those issues. I am here simply to "put to bed" some of the objections and myths regarding Synthetic Lubricants (including Motor Oil).

Synthetic Lubricants (Motor Oil) -- Objections & Myths

Let's put to bed some of the objections you will hear concerning the use of synthetic engine lubricants (some are old debates ... some are new):

Myth #1: Synthetic motor oils damage seals.

Untrue. It would be foolhardy for lubricant manufacturers to build a product that is incompatible with seals. The composition of seals presents problems that both petroleum oils and synthetics must overcome. Made from elastomers, seals are inherently difficult to standardize. Ultimately it is the additive mix in the oil that counts. Additives to control seal swell, shrinkage and hardening are required, whether it be a synthetic or petroleum product that is being produced.

Myth #2: Synthetics are too thin to stay in the engine.

Untrue. In order for a lubricant to be classified in any SAE grade (10W-30, 10W-40, etc) it has to meet certain guidelines with regard to viscosity ("thickness"). For example, it makes no difference whether it is 10W-40 petroleum or 10W-40 synthetic, at -25 degrees centigrade (-13F) and 100 degrees centigrade (212 degrees F) that oil has to maintain a standardized viscosity or it can't be rated a 10W-40.

Myth #3: Synthetics cause cars to use more oil.

Untrue. Synthetic motor oils are intended to be used in mechanically sound engines, that is, engines that don't leak. In such engines oil consumption will actually be reduced. First, because of the lower volatility of synthetic lubricants. Second, because of the better sealing characteristics between piston rings and cylinder walls. And finally, because of the superior oxidation stability (i.e. resistance of synthetics against reacting with oxygen at high temperatures.)

Myth #4: Synthetic lubricants are not compatible with petroleum.

Untrue. The synthesized hydrocarbons, polyalphaolefins, diesters and other materials that form the base stocks of high quality name brand synthetics are fully compatible with petroleum oils. In the old days, some companies used untested ingredients that were not compatible, causing quality synthetic lubricants to suffer a bad reputation. Fortunately, those days are long gone. Compatibility is something to keep in mind, however, whether using petroleum oils or synthetics. It is usually best to use the same oil for topping off that you have been running in the engine. That is, it is preferable to not mix your oils, even if it is Valvoline or Quaker State you are using. The reason is this: the functions of additives blended for specific characteristics can be offset when oils with different additive packages are put together. For optimal performance, it is better to use the same oil throughout.

Myth #5: Synthetic lubricants produce sludge.

Untrue. In point of fact, synthetic motor oils are more sludge resistant than their petroleum counterparts, resisting the effects of high temperatures and oxidation. In the presence of high temperatures, two things happen. First, an oil's lighter ingredients boil off, making the oil thicker. Second, many of the complex chemicals found naturally in petroleum base stocks begin to react with each other, forming sludge, gums and varnishes. One result is a loss of fluidity at low temperatures, slowing the timely flow of oil to the engine for vital engine protection. Further negative effects of thickened oil include the restriction of oil flow to critical areas, greater wear and loss of fuel economy. Because of their higher flash points, and their ability to withstand evaporation loss and oxidation, synthetics are much more resistant to sludge development.

Myth #6: Synthetics can't be used with catalytic converters or oxygen sensors.

Untrue. In fact the very low ash content of synthetics will extend the life of every exhaust system component.

Myth #7: Synthetics void warranties.

Untrue. No major manufacturer of automobiles specifically bans the use of synthetic lubricants. In point of fact, increasing numbers of high performance cars are arriving on the showroom floors with synthetic motor oils as factory fill. Which may not make the dealers too happy since oil changes usually lead to other service work.

Myth #8: Synthetics last forever.

Untrue. Although some experts feel that synthetic base stocks themselves can be used forever, it is well known that eventually the additives will falter and cause the oil to require changing. However, by "topping off", additives can be replenished. Through good filtration and periodic oil analysis, synthetic motor oils protect an engine for lengths of time far beyond the capability of non synthetics. Amsoil's unique additives packages allow for extended drain intervals.

Myth #9: Synthetics are too expensive.

Untrue. Tests and experience have proven that synthetics can greatly extend drain intervals, provide better fuel economy, reduce engine wear and enable vehicles to operate with greater reliability. All these elements combine to make synthetic engine lubricants more economical than conventional non synthetics. In Europe, synthetics have enjoyed increasing acceptance as car buyers look first to performance and long term value rather than initial price. As more sophisticated technology places greater demands on today's motor oils, we will no doubt see an increasing re-evaluation of oil buying habits in this country as well.

There are other OBJECTIONS, MYTHS and NON-TRUTHS circulating the forums, garages, and race tracks. The nine above are just a few that I wanted to address.

***** Conclusions *****

Since their inception, manufacturers of Synthetic Motor Oils have sought to educate the public about the facts regarding synthetics, and the need for consumers to make their lubrication purchasing decisions based on quality rather than price. As was the case with microwave ovens or electric lights, a highly technological improvement must often overcome a fair amount of public skepticism and consumer inertia before it is embraced by the general population. But the word has been getting out as a growing number of motorists worldwide experience the benefits of synthetic lubrication. The wave of the future, in automobile lubrication, is here, and AMSOIL has lead the march, recently celebrating their 30th year in business. For the environmental enthusiasts, the use of synthetics could reduce waste oil disposal by 80%, so if environment is your thing, then synthetic lubricants should be your choice.

When it comes to SYNTHETIC MOTOR OILS, having a firm understanding of their benefits is invaluable.

Eight reasons why synthetics are better for today's motorist and worth the extra upfront cost.

1) They improve fuel economy so that vehicles get better mileage out of every tank of gas.

2) They offer superior wear protection so that engines last longer.

3) By reducing friction they help engines run cooler.

4) By reducing deposits engines run cleaner and perform more efficiently.

5) Due to lower volatility they reduce oil consumption.

6) They have been proven to provide more horsepower.

7) They resist oxidation and breakdown, reducing varnish and sludge, keeping valves and rings from sticking.

8) Low pour points and cold weather pumpability make winter starts much easier.

When combined with extended drains, premium synthetic motor oils offer these additional benefits:

1) Synthetics save you money since the life-cycle costs are less than conventional (crude oil based) products.

2) They save you time (and money) with the convenience of extended drain intervals.

3) They reduce waste - since there is less used oil (and fewer empty containers) to dispose of.

4) They conserve a natural resource, since synthetic lubricants are made from liquid natural gas (not crude oil).
