Many oil change centers say they recommend what manufacturers recommend for oil change intervals which are 3000 to 5000 miles. This is simply not true.
Today's manufacturers recommend up to 15,000 mile changes and recommend high quality lubricants. The service believes it must sell at 3000 miles to survive.

Note that OEM branded lubricants are often thought of being superior when in fact they are lower in grade than shelf brands.!

"Three primary factors are normally responsible for oil failure"

Oil that becomes too thin, too thick, or too acidic has exceeded its useful life.

Dan Peterson's Tech ArticleBecause they work to suspend contaminants and by-products of combustion, it is not uncommon for gasoline and diesel oils to become dark. It may be more noticeable in some applications. It does not mean the oil is failing or must be changed.
Fortunately, a number of different tools are available that measure motor oil’s condition and its ability to continuously protect and perform its other key functions.
When motor oil exceeds its useful life or is impacted by a mechanical defect, it most commonly becomes too thin to separate metal parts, too thick to pump or too acidic for continued use.

Too Thin
When oil becomes too thin, it fails to provide the required oil film thickness to
separate metal surfaces. Different engine designs require different starting oil thickness
or viscosity. Viscosity at 100 °C is one of the most highlighted oil properties and is a good indicator of adequate oil film thickness in an engine at operating temperature.

A number of things can cause engine oil to become too thin to protect engine
parts. Excessive mechanical shear can thin oil to the point of causing issues with
engine protection. As motor oil cycles through the engine, it is exposed to shear stress in the engine’s upper end, piston walls and bearings that reduces its shear strength. Continuous exposure to these conditions causes oils built with inferior shear stability to thin excessively, leaving critical engine parts susceptible to metal to metal contact.

Fuel contamination of the oil sump is another major cause of excessively thin engine oil. Both gasoline and diesel fuel are thinner than engine oil and when mixed, the oil’s viscosity, film thickness and ability to separate parts are significantly reduced. While a small amount of fuel dilution is relatively common and does not have a material impact on oil life, excessive fuel dilution in mechanically compromised equipment is much
more harmful.

Too Thick
When it comes to oil, although it may seem like “the thicker, the better,” oil that is too thick is just as detrimental as oil that is too thin. Excessively thick oil is the most commonly discussed oil failure and the subject of many big oil company marketing campaigns.
When oil becomes too thick to flow to engine parts, these areas are starved of
oil, resulting in metal-to-metal contact that can lead to catastrophic engine damage.
The precursor to sludge is oil that has become much thicker than its original
design. The cause is a complex chemical reaction involving heat, combustion byproducts
and oxygen combining to create chemical attack on the oil molecules. The resulting chemical reaction creates a much thicker substance that does not flow or protect as well as the original oil. When the reaction continues, sludge begins to form in areas of higher localized temperature and low flow. While some varnish is normal, sludge is a sign of excessively degraded oil that needs to be replaced. In order to inhibit sludge and varnish, the oil must resist attack by oxidation forces. Synthetic base oils have a much higher
level of saturated molecules that inherently resist this constant bombardment. Additionally, antioxidants are added to either reduce the formation of free-radical oxidation precursors or soak up these precursors once they form.

Another cause of oil thickening, primarily affecting diesel oils, is excessive soot loading
in mechanically unsound engines. Diesel oils are designed to handle some soot contamination, but when the soot overloads the available dispersants in the oil, the oil thickens. The agglomerated soot particles reach a critical size and cause excessive wear commonly seen in diesel liners.

Too Acidic
Acids are a normal by-product of burning fossil fuels. Different fuel types, engines and combustion conditions create varying levels of acid formation. These acids, transferred via blow-by gases, are carried away to the engine oil. Oils are designed with a detergent that neutralizes these acids before they accumulate and cause engine damage. The detergent level is measured with a test called Total Base Number (TBN). This measure of alkalinity drops over the life of the oil and reaches a critical level when the oil can no longer consume the acids created by combustion. When TBN reaches a critical level,
acids build up quickly and attack the surfaces most susceptible, including yellow
metals and lead-lined bearings. Without correction, this condition quickly worsens
and results in excessive chemical wear. Although less common, this failure mode
can cause significant damage if left uncorrected.

AMSOIL synthetic motor oils are formulated to provide a broad level of overall protection, evidenced by guaranteed
extended drain intervals. Synthetic base oils help resist oxidative decomposition,
and a properly balanced, high-quality additive package helps keep contaminants
in check and engines running for a long time.


No longer settle for the typical quick lube oil change with no wear protection, Results in no added performance, poor cold weather flow properties, winter stress, leaves deposits, totally lacking any quality control in the vat (you don't even know what really is in there), and does nothing to extend life to your vehicle. AMSOIL's wear protection earns us customers for one major reason - noticeable performance.

We represent the largest AMSOIL Supply and service, and the top 5 in new accounts in the US and 6th in total sales. We can meet any need. This sales monster is homed right here in Sioux Falls!!

Why haven't the Big Oil Lubricant manufacturers informed consumers of the vast improvements to gasoline engine oils since the 1996 requirement of ILSAC GF-1 then on to more modern performance categories such as GF-2, GF-3 and GF-4? They know it's just to easy to keep you coming back at 3000 miles.

Are you aware of the money you are loosing in your company fleet? Did you know scheduled service is a thing of the past? The manufacturing industry is saving billions with higher quality lubricants and oil analysis. AMSOIL lets you fleet service your vehicles based on established guaranteed intervals. Please review our fleet study how we saved a pest control business in Minnesota $77,000 in one year with a fleet of 60 Ford F-150 trucks.

We also did a study with Waste Management and saved them millions on their Duluth trash truck fleet.

Drive more than 4000 miles per month? The bypass filter system eliminates oil changes.

STOP Changing your OIL!
When using AMSOIL, you may want to consider the By-Pass filtration systems. Change oil at 200,000+ oil intervals. Just change the full flow (EA OIL Filter and BE series Bypass filter) and by-pass unit yearly and top off. We recommend oil analysis after each cycle of new filters at least to monitor so you have full knowledge of the life and superiority of the AMSOIL product, We have prepaid shipping kits available. We recommend using Oil Analyzers as they specialize in synthetic oil testing.

Reduce dependence on foreign oil. AMSOIL has the solution. Add 8 to 10% to your mileage. You can normally reach 25,000 miles or one year before draining your oil.

AMSOIL's ASE Commercial Grade 100% Synthetic 10W30/.SAE-30 has become my favorite product to sell here locally in Sioux Falls.
Number one, the original design feature was extended engine life and high temperature performance but it's now selling just fine due to the fuel consumption reduction.

But here are some other reasons to consider using it in all your hard working motors now:

MANUFACTURERS POSITION: Briggs and Stratton owners manual quote:

* “Air cooled engines run hotter than automotive engines.  The use of  non-synthetic multi-viscosity oils (5W-30, 10W-30, etc.) in temperatures above 40°  F (4° C) will result in higher than normal oil consumption.”

See for yourself!
It is formulated with premium synthetic base oils that exceed both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements. Unlike conventional SAE 30 motor oils, AMSOIL ASE has a naturally high viscosity index and does not contain paraffin (wax). It has a -38°F pour point and qualifies for SAE 10W, making it an "all season," multi-grade lubricant with a wide operating temperature range. Reduces wear an average of 45% meaning you keep your engine in operation for years beyond what you would expect using OEM recommended oils.

Resists Heat and Reduces Oil Consumption
AMSOIL engineered Formula 4-Stroke® Small Engine Oil to withstand the high temperatures of hard working diesel and gas engines. It effectively resists oxidation and oil vaporization to control oil thickening (88% less) and reduce oil consumption (65% less). AMSOIL ASE lasts longer in service than conventional oils and keeps engines clean for peak operating efficiency.

Use AMSOIL ASE in your small garden equipment, commercial engines, generators and snow removal tools.Excellent For Transmission Systems
AMSOIL Formula 4-Stroke® Small Engine Oil is a shear stable formulation that contains no friction modifiers. It will not break down during rigorous mechanical activity, making it ideal for hydraulic or hydrostatic systems and chain cases. It is wet clutch compatible and designed to prevent clutch slippage in commercial or recreational transmissions. AMSOIL Formula 4-Stroke® Small Engine Oil protects gears and bearings during high-demand, commercial duty service.




A car’s engine needs oil to run without damage. Let the oil run out, the engine seizes
and you’re looking at a complete rebuild or buying a new engine. AMSOIL Dealer Mark Corey of Olathe, Kan. discovered, along with one of his customers that AMSOIL synthetic oil has changed the rules about oil and engines. As Corey tells it, AMSOIL retail customer Rob Barrette of Overland Park, Kan. ran over a metal and concrete protrusion with his 2000 Volkswagen Jetta TDI.

“It was late at night and he thought things were OK after the impact,” Corey said. “The
next morning Rob unknowingly drove his car more than 10 miles without oil in the crankcase and the oil pressure light on. “When he got home he called me to ask if the light being on was a bad thing. I told him that driving any distance with the oil pressure light on was bad.” Corey had serviced the car in October 2007 with AMSOIL Synthetic 5W-40 European Engine Oil (AFL), which was in the crankcase for a little more than 6,800 miles. “I told Rob that I would pull the old pan and inspect for damage,” Corey said. “The odometer read 141,718 miles. The pan sounded hollow, and the last few ounces of oil were dripping out of the cracked aluminum oil pan.
I let Rob know of the grim possibilities of a burned-up engine and turbocharger.”
Offering some hope for this bleak picture, Corey told Barrette stories of others who had been running AMSOIL in their vehicles and lost the oil while driving.
The crack that likely appeared the night before had become bigger with the vibration of driving that morning.
“Expecting the worst, I pulled the pan and checked thoroughly,” Corey said. “I felt it was a gamble as I installed a new oil pan and fresh AMSOIL.”
After the pan gasket sealer had some time to cure,
Corey started the car. “The little VW diesel ran as quietly and smoothly as
ever,” he said. “After a 20-mile test drive, I had Rob driveback to his house. I told him how lucky he was.
“A couple of weeks later, Rob brought the car by to have me check it. I pulled the dipstick out and the oil was full and looked great. Rob's mom had acquired this
car one year earlier as a very well-maintained creampuff from a meticulous owner. The 142,000-mile engine was still in near-perfect condition.”

  • Cars & Trucks made before 1995 need oils with more anti-wear additives and better quality detergents.
  • Drivers discovering top quality (real) synthetics do indeed increase fuel mileage.
  • New lubricant trends demanded by industry are developed well before the engine and transmission technologies hit the marketplace. This allows AMSOIL to further develop their product even further while the competition arrives late testing their product after the requirement goes live.
  • New emission systems demand oils, which can take more heat and leave fewer deposits. Currently diesel engine changes have created problems which demand more stable base stocks. We have them and you save more fuel to boot!
  • OEM Automatic Transmission Fluids are limited to light duty use. AMSOIL ATF and Low Viscosity Trans Fluid cuts temperature significantly and delivers more power to the wheels. Our transmission fluids continue to be well ahead of the industry because of AMSOIL's relationship with suppliers.
  • They are demanding better lubrication qualities from the oil to improve fuel economy.
  • Commercial vehicles Require synthetics in transmission and drivetrain parts to retain extended warranties. (And better power transfer).
  • Environmentally we can not go on disposing of the millions of gallons of oil each year that is the bi-product of 3,000 mile oil change intervals - Imagine if everyone changed their oil at say 7,500 miles instead. The used oil disposal problem would be cut by 50%. Yes 50%, not just 1 or 2% - Now consider the impact of a 25,000 and beyond oil change interval.
  • OEM fill and recommended product now from several lines such as Eric Buell Motorcycles.
  • AMSOIL is MADE in USA.
