AMSOIL Applauded for Extended Drain Technology
AMSOIL founder A.J. Amatuzio coined the phrase extended drain intervals back in 1972 with the introduction of AMSOIL 10W-40 Synthetic motor oils, formulated for 25,000-mile/one-year drain intervals. Not only was AMSOIL Synthetic motor oils the first synthetic engine oils to pass American Petroleum Institute (API) service requirements, AMSOIL. was the only motor oils company promoting oils drains beyond 3,000 miles.
Today, motorists are still bombarded with propaganda from the major oils companies promoting 3,000-mile oils changes. However, the industry is slowly but surely coming around. Vehicle manufacturers typically suggest 5,000- to 7,500-mile intervals in their owners manuals, and many manufacturers have also started incorporating oils life monitors into their vehicles, allowing motorists to safely extend drain intervals by monitoring oils life and alerting drivers when the oils needs changing. Competing oils companies have also begun marketing their own synthetics, some claiming service lives extending beyond 3,000 miles.
Lubes-n-Greases Automotive Editor David McFall, once with the American Petroleum Institute recently tackled the issue of extended drain intervals in his March column, criticizing the standard 3,000-mile oils change and referring to the American motor oils market as shackled.
In Europe the average engine oils drain interval for current gasoline-fueled cars is about 10,000 miles,& explains McFall. In the United States, indicates the Automotive oils Change Association, the average drain interval followed by most drivers is somewhat less than 5,000 miles—one-half of Europe's.
Every year in the United States, this too-short drain interval results in the unneeded production of 300 million to 400 million gallons of engine oils; excess consumer expenditures of around $1.5 billion; and tens of millions of unnecessary oils changes.
Not only are these unnecessary oils changes an expense to consumers, explains McFall, but they have an environmental cost as well. The added environmental cost of having an average 5,000-mile oils drain interval (instead of 10,000 miles, as in Europe) may be nearly 100 million gallons of engine oils being dumped, untreated, into the U.S. environment annually.
McFall's examination of Mobil 1, Shell and AMSOIL demonstrates the differences among companies who are shackled to the current system and one who isn't
According to an ExxonMobil spokesperson, Car owners should follow the oils change intervals specified by the manufacturer. We believe it is inappropriate to recommend drain intervals that may conflict with those set forth by the car manufacturer's specifications.
Here, in a nutshell,& says McFall, is this observer's take on ExxonMobil's and the oils industry's 'owner's manual' position: It is designed solely to increase motor oils sales. He backs it up by mentioning that Mobil 1 SuperSyn motor oils claims to meet European ACEA A5 and B5-02 specifications, two specifications intended to extend oils drain intervals. If the oils can be used in Europe for extended drain intervals, why doesn't ExxonMobil notify U.S. consumers of that capability? asks McFall.
Although Shell oils Products, owner of Pennzoils-Quaker State, has broken through the shackles enough to offer an API unlicensed oils specially formulated for higher mileage engines, they make no mention of a recommended drain interval, preferring instead to avoid the issue and keep consumers in the dark.
McFall marvels at the success of the independent motor oils company that offers drain intervals up to 11 times longer than the standard interval offered by conventional oil, saying, Purists can sniff that AMSOIL's data isn't derived from a controlled field study, but the sheer mountain of vehicle miles over three decades, and the absence of any confirmed performance, wear or maintenance issues, speaks volumes.
McFall sums up his column by highlighting the true value of AMSOIL Synthetic motor oils, stating the cost may be two to three times higher than most retail conventional oil but if you can securely count on a 15,000- to 25,000-mile drain interval, it's a flat-out bargain, not to mention providing a clear environmental bonus.
So, what is it that allows AMSOIL Synthetic motor oil to be used for extended drain intervals, while other oil must be changed significantly sooner? First, the synthetic base stocks with which AMSOIL Synthetic motor oil are formulated are worlds apart in quality compared with conventional base stocks. The synthetic molecules are uniform in size and shape, resisting the vaporization that boil off the smaller molecules of conventional motor oil and leaves behind a thicker, higher viscosity oils that compromises engine protection. AMSOIL Synthetic Motor Oil surpass even the most stringent European volatility standards, providing superior protection for extended drain intervals.
Second, AMSOIL spares no expense when it comes to additives, selecting the most robust additive packages on the market. These additives keep AMSOIL motor oil shear stable, resist the degrading effects of varnish and sludge, keep engine components clean and deposit-free and effectively resist rust, corrosion and foaming.
By using only the highest quality synthetic base stocks and additives available, AMSOIL Synthetic motor oil are capable of extended drain intervals, all while maintaining performance, providing long-term wear protection and fuel economy, keeping engines clean and deposit-free, providing cold weather starts and protecting against rust and corrosion.
