Synthetic Blend Oil : These have a dose of synthetic oil mixed with organic oil, and are formulated to provide protection for somewhat heavier engine loads and high temperatures.

This generally means they're less volatile, so they evaporate far less, which reduces oil loss and increases fuel economy. These oils are popular with drivers of pickups or SUVs who want extra protection for activities that put more stress on the engine, such as hauling heavy loads. They're also much less expensive than full synthetics—sometimes just pennies more than a premium conventional oil. Higher-Mileage Oil : Today's vehicles simply last longer.

If you prefer to pay off your car and run the mileage well into the six figures, you have another oil choice:, oils formulated for higher-mileage vehicles. Almost two-thirds of the vehicles on the road have more than 75, miles on the odometer. Consequently, oil companies identified this as an area of customer interest, and have new oils they're recommending for these vehicles. When your vehicle is somewhat older and has considerably more mileage, you may notice a few oil stains on the garage floor.

Engine seals such as those around the crankshaft may have hardened and lost their flexibility, so they leak and may crack, especially at lower temperatures.

Higher-mileage oils are formulated with conditioners that flow into the pores of the engine seals to restore their shape and increase their flexibility. Most rubber seals are designed to swell just enough to stop leaks, and oil refiners pick their "reswelling" ingredients carefully.

Valvoline showed us the performance data of one of their seal conditioners that caused most seal materials to swell while reducing the swelling of one seal material that tended to expand too much from the ingredients found in some other engine oils. You also may have noticed some loss of performance and engine smoothness due to engine wear on your higher-mileage vehicle. These higher-mileage oils also have somewhat higher viscosities. Even if the numbers on the container don't indicate it, there's a fairly wide range for each viscosity rating and the higher-mileage oils sit at the top of each range.

They may also have additives to improve their viscosity index. The result? They seal your pistons better against their cylinder walls and won't leak as much through larger engine bearing clearances that have worn down with time. They also may have a higher dose of antiwear additives to try to slow that wear process.

If you have an older vehicle, these features may mean more to you than what you might get from a full synthetic at a fraction the price. Although a higher second number is good, the oil also has to be robust , lasting for thousands of miles until the next oil change.

Oil tends to lose viscosity from shear, which is the sliding motion in the tight clearances between metal surfaces,such as those found in bearings. So, resistance to viscosity loss—called shear stability—is necessary to enable the oil to maintain the lubricating film between those parts.

Unlike antifreeze , 95 percent of which is made up of one base chemical typically ethylene glycol , petroleum-based engine oil contains a mixture of several different types of base oils—some of which are more expensive than others. Oil companies typically pick from a selection of five groups, each of which is produced in a different way and in different viscosities.

The more expensive groups are more highly processed, in some cases with methods that produce a lubricant that can be classified as a synthetic. The so-called full synthetics contain chemicals that may be derived from petroleum but are so altered that they're not considered natural oil anymore. For example, one custom blend contained 10 percent polyalphaolefins PAO , which is the most common type of chemical used as the primary ingredient in a full synthetic oil.

The base oil package in any oil makes up anywhere from 70 to 95 percent of the mix; and the rest is composed of additives. Some base oils have natural characteristics or ones that derive from their processing, which reduce or eliminate the need for additives.

Although some additives make improvements lubrication, they don't necessarily have great lubricity on their own. The ingredients in an additive package differ in cost, but price is just one factor. Some additives work better in certain combinations of base oils. Likewise, some less expensive base oils are a good choice for a blend because of the way they perform with popular additives.
