Farmers can save as much as 50% on oil related costs in typical farm operations. There are additional savings in less labor, less down time (equipment is PRODUCTIVE ALL THE TIME and equipment lasts longer (less replacement costs)!
After 409,000 miles without an oil change, this 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.
Colonial Heights, Virginia -- "I didn't see any surprises in there at all. Based on what we had with the V-8, it came out the way we expected," said owner/operator Haywood Gray of his 1990 Mack E7-400 engine.
It came out in good shape, exactly what you'd expect for a well-maintained engine with 600,000 miles -- yet the engine's oil had not been changed for 409,000 miles! Here's the story.
Gray began using AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil (AME) in the E9-400 V-8 engine of a 1984 Mack truck 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.
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 Lubrizol, a major oil additive manufacturer.

Additionally, LEAD AND IRON IS FAR BELOW EXPECTED AND COMPARED TO TRUCKS USING CONVENTIONAL OIL! The engine showed light to moderate wear throughout, just as an engine in similar service and lubricated with conventional oil changed at 15,000 to 20,000 mile intervals would show. In fact, according to the engine rater the parts he examined -- cylinder liners, pistons, rings, bearings, valve train components -- could have been put right back in the engine and would have continued to provide the good, dependable service they had provided all along -- after 409,000 miles without an oil change!
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 Marine 15W-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.
Gray's 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 showed that AMSOIL used in extended drain interval programs consistently delivered lower rates of engine wear than conventional oils used in conventional drain interval programs.
"Synthetic base stocks, 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."
"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 recommends standard extended drain intervals for each product and application or drains determined according to the findings of used oil analysis, like Haywood Gray's are. Either way, 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 Ð truckers win with less downtime and oil expense and they win big with reduced engine wear."
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 that's protection!
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.
Customers like Haywood Gray "trendline" their oil analyses. Trend lining 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.
The AMSOIL oil analysis program puts technologically advanced testing equipment in the hands of experienced diagnosticians to deliver accurate, reliable, useful results. Contact your AMSOIL Dealer for details!





In the chart above it shows 1) for an oil to pass European Standards it can not evaporate at a rate of 13% or more. 2) You can see what the American oils are like on the chart, however, AMSOIL's rate is only 7.6%!
AMSOIL TOOK AN EARLY LEAD IN DEVELOPING FUEL EFFICIENT LOW VISCOSITY LUBRICANTS FOR TRUCKING AND OTHER HEAVE-DUTY DIESEL APPLICATIONS with the introduction of AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil. Independent testing verifies its outstanding fuel economy benefit: trucks equipped with Series 3000 in the engine and AMSOIL lubes in the drive train had an 8.2 percent improvement over conventionally lubricated trucks!

ONE MILLION MILES, FOUR OIL CHANGES!
This trucker saved at least $15,000 on oil changes because he used AMSOIL! "That could be the difference," he says, "between staying in business or not."
MICHIGAN - 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 analysis 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 in business or not."
Cars and Motorcycles
Stanick and his family use AMSOIL products in their cars and motorcycles, too. "I used AMSOIL in my wife's Olds Cutlass Ciera. 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 to Series 2000 Synthetic 0W-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."
NEW TRUCK
Stanick now owns a truck with a 1994 Detroit Diesel Series 60425 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 load. It was three in the morning and my son was driving. Suddenly, all the dash lights came on.
"We pulled over, shut down the truck and looked under the hood. A filter had come loose and all the oil had been pumped out of the engine. Every drop."
"Now that's a $25,000 engine that we ran without oil! But once we got the filter fixed and put some oil back in 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."
