So you ask...
"What's extended drain intervals all about ?"
GM (General Motors) and the state of
ExxonMobil Follows AMSOIL into Extended Drain Market
Motor oil technology has gradually progressed since the days of the earliest automobiles. In those days, standard motor oil drain intervals were between 500 and 1000 miles, and motorists had to switch viscosity grades with the changing of the seasons. The development of oil filtration and additive technology in the 1930s allowed drain intervals to increase to 2000 and later 3000 miles, while the development of viscosity modifiers in the 1940s allowed the formulation of multi-grade oils that could be used in both hot and cold temperatures.
According to AMSOIL Vice President Alan Amatuzio, the introduction of ExxonMobil extended drain oil is long overdue. "While AMSOIL INC. has certainly proven that extended drain intervals provide valuable benefits," said Amatuzio, "the fact that ExxonMobil is finally saying the same thing brings the message to even more people. ExxonMobil's move is significant in that more consumers will now recognize AMSOIL as the pioneer in extended drain oils and will benefit from the advanced technology we introduced 33 years ago."
ExxonMobil recently announced a new line of
motor oils recommended for extended drain intervals.
Mobil backed off 25,000 mile oil change
intervals in 1974.
AMSOIL stands apart from the competition.
A close look at ExxonMobil’s new long drain motor oil line reveals that two are petroleum based, one is a synthetic blend and only one, Mobil 1 Extended Performance, is a full synthetic. The petroleum based products are recommended for 5000 mile drains, the synthetic blend for 7500 mile drains and Extended Performance for 15,000 mile drains. However, a look at the fine print reveals that ExxonMobil is still recommending drivers follow the oil drain recommendations listed in their owners manuals during the warranty period. AMSOIL synthetic motor oils are recommended for 25,000 mile or one year drain intervals in both new and older vehicles. The AMSOIL warranty stands behind this recommendation.
AMSOIL has recommended 25,000 mile/one year
drain intervals since 1972.
Vehicle manufacturers are pushing for extended
oil drain intervals.
The motor oil industry is faced with the
extended oil drain interval issue.
Here is more about extended drain intervals.......
Today's motorist is confused. For several years GM and several other car manufacturers have been installing a monitor that uses a light on the dash to indicate when it's time to change oil. But oil companies and oil change facilities continue pushing the 3000 mile oil change interval. What's a car owner to
do? The right approach is to follow the light, and to use AMSOIL XL, the one oil designed for today's OEM approved extended drain situations.
Here is real extended drain for you !
409,000-Mile Oil Drain Interval Mack Engine Teardown
After 409,000 miles without an oil change, the AMSOIL-protected Mack E7-400 engine in this truck was as wear-free as an engine in comparable service treated to TWENTY TIMES the oil changes.
Gray began using AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil (AME) in the E9-400 V-8 engine of his first truck, a 1984 Mack, after the engine accumulated 45,000 miles. For 280,000 miles, Gray changed his oil at 40,000-to 60,000-mile intervals though his oil analysis reports showed, without exception, that the oil was good for continued use. At 325,000 miles, Gray increased his oil drain interval to 100,000 miles. The engine was torn down at 600,000 miles when Gray decided to sell the truck. The cylinder liners, bearings, pistons, rings and oil pump, all treated to extended oil drain intervals with AMSOIL, were found to be in excellent condition. Gray continued using AMSOIL AME in the engine of his new truck, a 1990 Mack with a E7-400 engine. With the new truck, instead of using 100,000 mile drain intervals, Gray began basing his oil drains on the findings of a used oil analysis program. He also installed an AMSOIL By-Pass Oil Filter. After 630,000 miles total and 409,000 miles without an oil change, the E7-400 engine was torn down by the local Mack dealership in December 1996 and its parts were examined by an engine rater from a major oil additive manufacturer.
Many factors enable AMSOIL to be safely used 20 times longer than petroleum oils may be used:
Stability AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil is far less prone to thermal and oxidative breakdown than are petroleum oils. Stability inhibits the formation of carbon deposits, varnish, sludge and acids, which helps the engine run clean and protected.
Neutralization ability While rapid TBN loss often renders conventional oils unfit for continued use, 12 Total Base Number (TBN) AMSOIL Synthetic Heavy-Duty Diesel and Marine15W-40 Motor Oil offers lasting protection against engine corrosion.
Viscosity retention Some conventional oils viscosity slips out of specification within a few thousand miles of an oil change. AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil neither loses viscosity as shear-prone oils do, which promotes wear during high temperature operations, nor gains viscosity as oxidation-prone oils do, which promotes wear during startup and cold temperature operations.
Grays successful use of AMSOIL synthetic motor oil in extended drain service is not unique. AMSOIL has conducted demonstrations with fleets all over North America. In each instance AMSOIL has been proven safe and effective in extended drain use. In fact, these studies show that AMSOIL used in extended drain interval programs consistently delivers lower rates of engine wear than conventional oils used in conventional drain interval programs.
The rater found the valve train components showed, very light wear. Very good. [I] find no wear on the shaft, which can be a heavily loaded area.
Southern over-the-road fleet AMSOIL was used in Cummins class 8 engines for 75,000-mile drain intervals; the fleets normal drain intervals were 15,000 miles.
Upper midwest grocery fleet AMSOIL was used in Cummins NTC 350 engines for 74,000-mile drain intervals; normal drain intervals were 12,000 miles.
Northern grocery fleet AMSOIL was used in Detroit Diesel Series 60 engines for 79,000-mile drain intervals; normal drain intervals were 20,000 miles.
Virginia Beach, Virginia owner/operator AMSOIL was used in Cummins 350 engine for 325,350 miles without a drain.
Midwestern trucking fleet AMSOIL was used in Detroit Diesel Series 60 engines for 60,000-mile drain intervals; normal drain intervals were 20,000 miles.
Northern tier over-the-road fleet In an ongoing demonstration, AMSOIL Series 3000 5W-30 is being used in a fleet of Cummins N-14 engines for extended drain service with oil drains based on the findings of used oil analysis. One change was performed at one year with 125,000 miles on the AMSOIL. The oil was recommended for continued use. Normal oil drains are done at 20,000 miles.
Except for normal top polishing on the push tubes the rater found, no wear to speak of. These can go right back in the engine and be used again. The push tubes were put back into the engine and are in use today.
I see no reason why it [the engine] couldn’t run on. Independent engine raterWHAT MAKES AMSOIL SO GOOD?
Synthetic basestocks, top-quality additives, and most importantly, more experience formulating synthetic motor oils than any other oil company, says AMSOIL Director of Technical Sales Dave Anderson.
AMSOIL first put a long-drain synthetic diesel oil on the market in 1975 and
since then has introduced three other long-drain synthetic diesel oils.
DOES AMSOIL OFFER A WARRANTY?
Yes. AMSOIL warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL products are used in full compliance with AMSOIL recommendations.
AMSOIL extended drain interval recommendations are set at a minimum of two times or more than the engine manufacturers recommendations as determined by oil analysis. Diesel operators who use AMSOIL for extended drains are fully protected.
Studies have proven time and again that extended drain intervals with AMSOIL are a win/win situation truckers win with less downtime and oil expense and they win big with reduced engine wear.
AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil Aces Test!
Haywood Gray has his used oil tested regularly to ensure the ongoing serviceability of the oil and well-being of the engine. In the engine oil report card, wear metals tell the whole story. A high wear metal content indicates a high rate of engine wear. In fact, most engine manufacturers publish upper limits on wear metals content at which an oil must be changed to assure continued engine protection. Even after 409,000 miles, AMSOIL protected better than Mack limits required. Now thats protection!
What Is Oil Analysis?
Oil analysis is a maintenance management tool that allows users to monitor equipment condition for maximum equipment life, maximum lubricant drain interval length and optimal downtime scheduling. Oil analysis saves users significant money by reducing equipment replacements and repairs, reducing the volume of lubricant purchased and destined for disposal and, most of all, by reducing downtime.
Oil analysis customers like Haywood Gray trendline their oil analyses. Trendlining involves comparing the results of previous oil analysis reports to those of the most recent report to establish trends in wear metals content, viscosity, acid content, acid neutralization ability and other characteristics as specified. Departures from established trends indicate a change in engine or lubricant condition and the information they provide may be used to correct abnormal conditions before they cause damage or failure.
What's Woody doing now?
This trucker saved at
least $15,000 on oil changes because he used AMSOIL.
MIDLAND, MICHIGAN-- Independent owner-operator Norman Stanick used AMSOIL Synthetic SAE 30 in his 1987 Caterpillar 3406 engine since the truck was new
(after breaking in the engine with another oil) until he sold it seven years and one million miles later.
He performed four oil changes during that period, basing his extended oil drain decisions on the findings of used oil analyses performed at 50,000 mile intervals.
After 848,000 miles, Stanick pulled the pan to fix a water leak. He decided to take a look at the main and rod bearings. He was there when the mechanic pulled them out. "There was not a shiny spot on any of those bearings. They miked out at new part measurements," said Stanick.
"I saved between $15,000 and $18,000 on oil changes. That could be the
difference between staying
Stanick and his family use AMSOIL products in their cars and motorcycles, too. "I used AMSOIL in my wife's Old Cutlass Cierra. We put 212,000 miles on it with eight oil changes and sold the car to a guy who's tickled pink with it.
"Now my wife drives a Chevy Lumina with a V6 engine. We switched it to Series 2000 Synthetic OW-30 Motor Oil and picked up three miles a gallon. The engine runs cooler. In fact, that oil completely changed that engine. It impresses me tremendously."
Stanick's son races a Honda 750, in which he uses AMSOIL Series 2000
Synthetic 20W-50 Racing Oil. "The first time he put the oil in, he picked
up a tremendous amount of horsepower. He came off
Stanick now owns a truck with a 1994 Detroit Diesel Series 60 425 engine. He uses AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil in it. He continues to use oil analysis and changes his oil at 250,000 mile intervals.
"Let me tell you a story. My son and I drive team. We were in California
pulling a 43,000 pound load.
"We pulled over, shut down the truck and looked under the hood. A filter
had come loose and all the
"Now that's a $25,000 engine that we ran without oil! But once we got the filter fixed and put some oil back it, it started right up and has run perfectly ever since. I'm sure AMSOIL saved my engine.
"I have no question I can run this engine two million miles with eight oil changes. People don't believe me. They tell me I'm crazy. I just smile all the way to the bank."
