Oil Drain Intervals on the Rise

The 3,000 mile oil change interval has been ingrained in the American consciousness for decades. Conventional motor oil companies aggressively push it, oil change centers remind their customers to return when another 3,000 miles have accumulated on the odometer and fathers teach their children to change their oil and filter according to a 3,000 mile schedule.

Vehicle Manufacturers

Vehicle manufacturers, on the other hand, aren't quite on the same page. A look at many recent-modern owners manuals reveals a recommended 5,000- to 7,500-mile oil drain interval, while European vehicle manufacturers recommend even longer drain intervals. As the service lives of spark plugs and transmission fluids have increased, consumers have demanded longer service intervals for motor oil as well. The introduction of electronic oil life monitors on modern vehicles is beginning to push drain intervals upward. Oil life monitors typically determine when oil should be changed based on engine operating conditions such as temperature, revolutions and speed.

Almost all 2005 and later General Motors vehicles are equipped with its Oil Life System, which makes use of a color-coded system to alert the driver when it's time to change the oil. A "yellow" condition indicates that it's time to think about changing the oil, while a "red" condition indicates that the oil is past its service life. According to GM, the typical drain interval for vehicles equipped with the Oil Life System is 8,500 miles, which will result in a savings of 6.6 million gallons of oil and $145 million for 2005 model-year drivers over the lives of their vehicles.

General Motors is actively seeking to extend oil drain intervals even further. In fact, the company recently asserted that 20,000-mile oil drain intervals are possible with existing engine technology and synthetic oils meeting current specifications, while 30,000-mile oil change intervals are achievable with appropriate motor oil quality and minor engine modifications.

"Drain intervals are a very specific goal for GM, and are being managed in a logical and planned fashion," says James A Spearot, director of GM's Chemical & Environmental Sciences Laboratory in Warren, Michigan. "Longer drain intervals are desirable to meet customer demands for reduced maintenance and convenience, and for the environmental benefits that come with less oil handling. And, in the end, longer drain intervals will help us with our warranty protection goals."

Motor Oil Companies

AMSOIL represented the lone voice for extended drain intervals in America for over 30 years, recommending 25,000-mile/one-year drain intervals. While extended oil drain intervals have been common in Europe for years, other American motor oil companies have mostly avoided recommending them, preferring instead to stick with 3,000-mile recommended intervals despite the contrasting recommendations of vehicle manufacturers and European motor oil companies.

In fact, Marc Graham, president of Pennzoil-Quaker State-owned Jiffy Lube International, was quoted in a 2001 Lubricants World interview as saying, "At [Pennzoil-Quaker State] we use a number internally that if we [shorten the drain interval] by 100 miles [for each car serviced], it would mean an additional $20 million in revenue for the company." He also explained that "if we could move our customers to get one more oil change per year, it's worth $294 million for the oil change alone and $441 million in revenue, when you include the ancillary products and services customers typically buy along with the oil change."

Today, with vehicle manufacturers recommending longer and longer drain intervals and the increasing use of oil monitoring systems, the practice of extending drain intervals has become more mainstream and forced more motor oil companies to take notice. ExxonMobil, for example, recently introduced a line of long drain motor oils, and other motor oil companies will likely follow. As more motor oil companies begin offering extended drain motor oils, the extended drain interval idea pioneered by AMSOIL over 30 years ago will become increasingly common.

According to a special report released May 2005 by the Motor & Equipment Manufacturers Association (MEMA), synthetic motor oils are key to extended drain technology: "Extended drain technology is primarily based on the availability of synthetic oils. While the additives in conventional, non-synthetic oils allow them to function longer than the traditional 3,000 miles, it is primarily the synthetic base stocks that allow the oil to last much longer. Synthetic oil offers many advantages in durability versus conventional petroleum oil and it is all based on the synthetic oil's superior heat and oxidation resistance. Synthetic oil is more accurately controlled at the molecular level and therefore can be engineered to resist the forces in an engine that work against oil durability."

AMSOIL offers a complete line of premium quality synthetic motor oils formulated for extended drain intervals.

Why Motor Oil Deteriorates

It is common knowledge that, at some point, engine oil must be changed. It's something that is preached relentlessly to vehicle owners by vehicle manufacturers, quick lubes and oil companies. But consumers are widely unaware of what exactly makes oil changes necessary.

Many factors contribute to a motor oil's demise, but it is essentially the accumulation of contaminants in the oil and chemical changes in the oil itself that make a motor unfit for further service. With time, it is inevitable that the oil will be contaminated by dirt or sludge, or succumb to the extreme pressures or temperatures found inside an engine. AMSOIL Motor Oils are formulated with the industry's most advanced synthetic base stocks and additive packages to combat the forces that deteriorate conventional oils. (read more)


What is the NOACK Volatility Test?
Volatization is a term used to describe what happens to a fluid as it is heated to the point it begins to "boil off." Upon reaching a certain temperature, oil will begin to lose some of its lighter weight molecules as they "boil off" and leave heavier weight molecules behind. Not only does this cause higher oil consumption, this process can also cause increased viscosity making the oil more difficult to circulate through the lubrication system. (read more)

"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."


FULL WARRANTY


AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
