Since applying a bottle of PolyGuard-1™ Oil Treatment to my engine I've experienced an 8% increase in fuel efficiency. Being a numbers guy I quickly did the math and it's saving me around $2 per fill-up. I change my oil every 3,000 miles so when I calculate the fuel savings and driving those miles I save about $22 per oil change. That savings more than covers the cost of the treatment. Basically the product more than pays for itself so I guess you could say I get all the engine protection I need for free! Or the more you drive, the more you'd save.

I've been using DWG's PolyGuard-1™ Oil Treatment ever since I've owned my current car. I use my car in my business and I'll admit that I often drive it harder than I should. I now have 160,000 miles on it and it still starts and runs just like when it was new. And if that's not impressive enough, I've actually ran it out of oil 3 times due to a leak I wasn't aware of and I believe the only reason why it's still running today is because I always added PolyGuard-1™ each time I changed my oil. With the price of cars today DWG's PolyGuard-1™ Oil Treatment has saved me a lot of money. Thanks DWG.

My families mini van now has over 300,000 kilometers (approx 200,000 miles) on it and I owe it all to DWG's PolyGuard-1™ Oil Treatment. My wife and I bought it new and I'm proud to say we've added the product to the engine at every oil change. Because of the oil treatment I get an 60 extra miles per tank compared to a business associate that drives the same van. With the price of gasoline the product pays me to use it. Today it still runs like it's brand new. I've really enjoyed the peace of mind that using the product has given me. Even in the sub-zero temperatures it starts easy and never labors. The engine runs so quiet that I often have to check to see if it's still running.

Before you read this article I want to point out the fact that the "Big-3" auto manufacturers do believe in oil additives. Each one of them have an oil additive manufactured for them and private labeled with their name on it. One uses a graphite based additive another uses a sulfur based product. You'll find it on the shelves in their parts departments. I understand why you might be surprised by that bit of news, we've never heard them promoting it have we? Heaven for bid that we should extend the life of the equipment they manufacture and sell. Have you ever looked at the corporate end of year reports of these companies and noticed that their income source in replacement parts is nearly double that of their new car sales income? Interesting? Why do you think that car parts don't seem to last as long? Some suggest that it's by design.

Because oil technology has made great strides in recent years, the thought that motor oils of today are capable of protecting engine parts and extending engine life better than ever before is understandable. Keep in mind though that the design of today's motor oils are still dictated by the manufacturers of today's engines. The oil designer follows a strict set of guidelines set forth the by the engine manufacturer just as it has been done for decades. They follow those guidelines so that they can place a label on the can that says; "meets manufacturers minimum requirements." It was recently pointed out to me that the engine manufacturers minimum requirements haven't changed since 1957. I found that odd knowing that the minimum demands we place on our engines today is significantly greater then the minimum demands of the fifties.

Did you see that it's based on the "minimum requirements?" Remember that the next time you buy a quart of store brand oil...it was also made by the company with the lowest bid.

It's no secret that an engine contains hundreds of moving parts that must be kept separate from each other by a film of oil. Whenever two parts slide or rotate, the resulting metal to metal contact can produce severe and unnecessary wear. An important function of motor oil is to establish a film of oil thick enough and strong enough to prevent metal-to-metal contact. The more an oil can accomplish this the longer a piece of equipment can last.

A second important function of motor oil is to reduce friction. Friction results from the resistance of engine parts to movement against each other. To experience that right now place the palms of your hands together and rub them against each other quickly for 10 seconds. You will feel an immediate increase in palm temperature. Can you imagine how quickly the moving parts in your engine would heat up and fuse together if you didn't have good lubrication?

Motor oils are required to do more than provide a lubricating film and reduce friction. A third important function is to act as a coolant and help remove the heat generated by the engine. The engines heat again comes from friction produced by closely fitted engine parts such as connecting rods and main bearings, camshafts, and piston rings. Though most people think that the radiator fluid is responsible for cooling the engine it actually only handles about 60% of that task. The engines oil handles the other 40%. This presents a good case for always keeping your oil at the correct level as specified by the manufacturer.

The ease of starting an engine depends not only on the condition of the battery and ignition, proper fuel volatility, and fuel to air ratio but also on the flow properties of the motor oil. If the oil is too viscous or heavy or thick at starting, it will impose enough drag on the moving parts that the engine cannot be cranked fast enough to start promptly and keep running. All of our friends in the northern parts, where temperatures drop each year, have most likely experienced this from time to time. That's why they make sure they change their engine oil to a lower viscosity before the temperatures drop. Viscosity is a measure of the oil's resistance to flow. A lower viscosity such as a single- grade 5W can flow easier in cold temperatures than a single-grade 40W. But then once the engine finally warms up to operating temperatures the 5W is not enough protection and now your engine needs 40W. Therefore engineers designed a multi-grade blend that could function in conditions as extreme as that. You've seen them as 5W-20, 5W-30, 5W-40, 10W-30, 10W-40 and so on. Here in Texas where temperatures can be extreme on the other end of the scale you'll find many owners using 20W-50. Be sure and always consult your owners manual for the recommended blend. But then again perhaps you should make a more intelligent decision and determine what's best for your engine.

With all of the internal parts of an engine being constructed basically of metal components, motor oils are blended with other additives that help to neutralize the foreign by-products that can occur in the crankcase. Fuel that blows by the rings, moisture that never evaporates because the engine wasn't operated long enough at normal operating temperatures, and there are many more. Those by-products can be corrosive to the internal metal parts so motor oil has a blend of additives that can help resist rust and corrosion. It just seems that no one can tell you how long it can actually resist the elements.

The efficient operation of an engine depends on the motor oil to do the following:

Permit easy starting.
Lubricate engine parts and prevent wear.
Reduce friction.
Protect against rust and corrosion.
Keep engine parts clean.
Cool engine parts.
Seal combustion pressures.
Prevent foaming.
Aid fuel economy.
