*NEW* AMSOIL Engine Fogging Oil |
|
| Amsoil Inc. has just unveiled a new product designed to protect your engine during long periods of storage. Some people are familiar with the term 'fogging an engine' which generally involves removing spark plugs and squirting oil into each cylinder to protect surfaces from rust and oxidation during prolonged periods of storage. It's also not uncommon to run a thicker mixture of oil and gas right before storing a 2-stroke engine to achieve similar results. However, neither of these are as effective as Amsoil's new fogging oil. The aerosal spray can be applied directly through the engine intake or carburetor as the engine is running and disperses to protect more surfaces than regular motor oil. This is particularly true on outboard motors and others engines that have horizontal cylinder orientations. This product is excellent for use on seasonal engines commonly found in two- and four-stroke recreational vehicles, hand held power equipment, small engines, construction and farm equipment, motorcycles, and any other engine that spends a significant amount of time without being started. |

AMSOIL Introduces World's First Oil Filter Cartridge for Diesel Applications with Nanofiber Technology.
AMSOIL INC. of Superior, WI has introduced a new premium, high efficiency cartridge oil filter utilizing nanofiber technology for Ford 6.0L diesel engines ranging from 2003 to 2006. The new EaO-88 is the world's first oil filter cartridge for diesel applications using advanced submicron full synthetic media. The EaO-88 provides an efficiency of 98.7% at 16 microns, significantly higher than the OEM filter.
The rigid construction of this filter is due to a polymeric center tube and end caps, along with its proprietary composition incorporating special grade nanofiber synthetic media, enabling the filter to last up to 1 year or 25,000 miles when used in conjunction with AMSOIL synthetic motor oil. Because of its improved oil flow, an additional benefit of this synthetic filter media is that oil is delivered to key engine components quicker, thus enhancing the lubrication process during cold weather starts.
Benefits include:
- Superior filtration efficiency
- Excellent flow characteristics
- Reduced engine wear
- Rugged and durable design
Fast Fact: A nanofiber is less than one micron in diameter. A human hair is 80 microns.
Motorcycle Oil Study
Here's an excellent article comparing over 20 different motor oils designed specifically for motorcycles. In the end, AMSOIL comes out on top for both sae 40 and sae 50 weight oils. I'm sure many people will discredit the article, since the tests were performed by AMSOIL. However, the tests performed were quite extensive, and the results speak for themselves. No other manufacturer has published any test results this conclusive, and yet several of them spend millions in advertising each year. If any of the other manufacturers could produce some test results that showed them to be superior, I would think that they would surely publish those results.
AMSOIL OUTPERFORMS MOBIL 1 ONCE AGAIN
AMSOIL performed more API comparitive motor oil testing this past November. Included in the testing was Mobil 1 Extended Performance motor oil, which did perform extremely well. However, AMSOIL still topped nearly every category with Mobil 1 finishing a close second in most cases. You can see the details for yourself by looking at the published results here. As for pricing, you can purchase AMSOIL through us, and have it shipped right to your door for roughly the same price you will pay for Mobil 1 off the shelf at your local retailer. Additionally, AMSOIL is rated for 25,000 miles versus 15,000 miles for Mobil 1. The choice is yours, but clearly, the best choice is still AMSOIL and the cheapest place to buy it is right here.

AMSOIL UNVEILS THE LONGEST LASTING OIL FILTER
 Since the early 70's, AMSOIL Inc. has been manufacturing synthetic motor oils designed to last 25,000 miles and beyond. Now, AMSOIL has introduced their new line of oil filters that are rated for 25,000 miles as well. Just last month, they released a new line of air filters rated for 25K miles between cleanings. At this point, AMSOIL now offers a total package that allows you to go 25,000 miles or 1 year, whichever comes first, without needing to stop at your local auto-repair shop for routine vehicle maintenance. This is a huge convenience for consumers to be able to go an entire year without needing to service their vehicles. In addition, the cost savings on yearly vehicle maintenance drops to an all-time low. Both of these new offerings from AMSOIL inherit the name 'Absolute Efficiency' and rightly so. No other manufacturer in the world makes an oil filter designed to last for 25K miles. Come to think of it, no other manufacturer in the world makes a synthetic oil designed to last that long either. |
 AMSOIL Inc. has just released their new line of Ea™ Air Filters featuring nanofiber technology that will be replacing the TS series. These new air filters cost slightly more than the TS series, but they offer better performance, capacity, efficiency, air flow, and filter life. The nanofibers allow these filters to capture far more of the small dirt particles from entering your engine, as compared to the cellulose and wet gauze offerings by Fram, K&N, and others.They also don't require the use of tack oil or any other cleaning products. Simply vacuum the dirty side of the filter, or use low-pressure air from the clean side to blast away the dirt particles. AMSOIL recommends they be cleaned once per year, or every 25,000 miles, whichever comes first. The filter life is rated for a minimum of 4 years or 100,000 miles, and they have been tested to over 120,000 miles while maintaining 99% efficiency. The cleaning intervals also coincide with AMSOIL's recommended oil change intervals, which allow motorists to get all their service work done in one convenient trip. The TS line of air filters will still be available while supplies last. If there isn't an Ea™ filter for your application, you can still use the Hastings line of premium quality filters. |
Comparative Motor Oil Testing
|
AMSOIL | Seven tests were run on the motor oils. The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability of engine oils. The High Temperature/High Shear Test (HTHS) measures a lubricant's viscosity under severe operating conditions. The NOACK Volatility Test measures the evaporation loss of oils in high temperature service. Pour Point indicates the lowest temperature at which a fluid will flow. Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity for combating acids. The Cold Cranking Simulator Test (CCS) measures a lubricant's viscosity at low temperatures and high shear rates. The Four-Ball Wear Test measures a lubricant's wear protection properties. The impressive test results show AMSOIL Synthetic 10W-30 Motor Oil outperformed the competitors in each test. |
Thin-Film Oxygen Uptake (ASTMD-4742)
|
The Thin-Film Oxygen Uptake Test evaluates the oxidation stability of lubricating oils. A mixture of the test oil and chemistries found in gasoline engine operation (oxidized/nitrated fuel, soluble metals and distilled water) are placed in a test vessel, which is pressurized with oxygen and placed in a heated bath. Anti-oxidant breakdown is evident when the oxygen pressure in the vessel rapidly decreases. At this point, the induction time (break point) of the oil is recorded. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil had the highest induction time of all the tested oils. In fact, it didn't reach its break point in over 500 minutes of testing.The superior oxidation stability of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively resist the formation of engine deposits and sludge, keeping engines running clean and efficient and extending oil life. It also resists thickening, maintaining its superior wear protection and lubricating properties and maximizing fuel efficiency. High Temperature/High Shear (ASTM D-4683)
|
The High Temperature/High Shear Test measures a lubricant's viscosity under severe high temperature and shear conditions that resemble highly-loaded journal bearings in fired internal combustion engines. In order to prevent bearing wear, it is important for a lubricant to maintain its protective viscosity under severe operating conditions. The minimum High Temperature/High Shear viscosity for a 30 weight oil is 2.9 cP. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil surpasses this minimum standard and displayed the highest High Temperature/High Shear viscosity in the group.The superior viscosity retention of AMSOIL Synthetic 10W-30 Motor Oil in the face of severe temperature and shear conditions allows it to provide continuous, unsurpassed protection for engine bearings, extending equipment life and preventing wear. NOACK Volatility (ASTM D-5800)
|
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. A maximum of 15 percent evaporation loss is allowable to meet API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL 10W-30 Synthetic Motor Oil outperformed its nearest competitor by over 30 percent.The extremely low volatility of AMSOIL Synthetic 10W-30 Motor Oil allows it to maintain its superior protective and performance qualities throughout extended drain intervals, even when faced with severe operating temperatures. In addition, oil consumption and emissions are minimized and fuel efficiency is maximized. Pour Point (ASTM D-97)
|
The Pour Point Test determines the lowest temperature at which a lubricant will flow when cooled under prescribed conditions. The lower a lubricant's pour point, the better protection it provides in low temperature service. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil has the lowest pour point of the tested oils.The low pour point of AMSOIL 10W-30 Synthetic Motor Oil allows it to maintain its fluidity in extremely low temperatures, reducing drag on moving vehicle parts, providing critical engine components with quick, essential lubrication and easing startup in cold temperatures. Wear is greatly reduced and equipment life is extended. Total Base Number (ASTM D-2896)
|
Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher a motor oil's TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil has the highest TBN of the tested oils.The high TBN of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively combat wear-causing contaminants and acids, providing superior protection and performance over extended drain intervals. Cold Crank Simulator (ASTM D-5293)
|
The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and startability. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold temperatures. 10W motor oils are tested at -25°C and must have a viscosity below 7000 cP to pass. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil is well below the maximum requirement, while many of the competing oils barely pass.The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures. Four Ball Wear (ASTM D-4172)
|
The Four Ball Wear Test determines the wear protection properties of a lubricant. Three metal balls are clamped together and covered with the test lubricant, while a rotating fourth ball is pressed against them in sliding contact. This contact typically produces a wear scar, which is measured and recorded. The smaller the average wear scar, the better the wear protection provided by the lubricant. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil produced the smallest wear scar of the tested lubricants.| AMSOIL Synthetic 10W-30 Motor Oil provides unsurpassed protection against engine wear. Equipment life is extended, and repairs, downtime and expenses are reduced. |
  AMSOIL INC.has been the leader in synthetic motor oil formulation since its introduction of the world's first API rated synthetic motor oil in 1972. By specializing exclusively in the synthetic lubricant technology, AMSOIL is able to optimize the most advanced chemistries available. The "Genuine Synthetic PAO Formulated" designation displayed on AMSOIL packaging indicates that the oils are formulated with Polyalphaolefin (PAO) synthetic base stocks. This chemistry is the industry's premier base stock technology. Unlike conventional mineral-based chemistries, AMSOIL PAO base stocks contain fully saturated, hydrogenated molecules and are free of wax and other impurities. Combined with an exact balance of premium additives, it delivers superior hot and cold temperature performance, resists oxidation and acid formation and provides long-term wear protection. AMSOIL "General Synthetic PAO Formulated" oils have shattered the parameters of the most rigorous industry testing and set the standard for all other motor oils. |

NOACK Volatility 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, increased oil consumption and excessive wear and emissions. A maximum of 15 percent evaporation loss is allowable to meet the API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil lost an extremely low 4.9 percent of its original weight during high-temperature service, maintaining its superior protective and performance qualities,while Mobil 1 SuperSyn 5W-30 Motor Oil lost 9.17 percent of its original weight. |
|||
Four Ball Wear The Four Ball Wear Test determines the wear protection properties of a lubricant by measuring the wear scars produced by four metal balls in sliding contact under the test parameters. The smaller the average wear scar, the better the wear protection provided by the lubricant. As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil completed the Four Ball Wear Test producing a smaller wear scar than the Mobil 1 SuperSyn 5W-30 Motor Oil. |
|||
Flash/Fire Point The Flash/Fire Point Test determines the lowest temperatures at which application of a flame will cause lubricant vapors to ignite (flash point) and sustain burning for five seconds (fire point). Lubricants with higher flash and fire points exhibit more stable volatility characteristics and are safer to use and transport. As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil has higher flash and fire points than does Mobil 1 SuperSyn 5W-30 Motor Oil. |
|||
Pour Point The Pour Point Test determines the lowest temperature at which a lubricant flows.The lower a lubricant's pour point,the better protection it provides in low-temperature service.As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil has a lower pour point than Mobil 1 SuperSyn 5W-30 Motor Oil. |
|||
Total Base Number Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity. The higher a motor oil's TBN, the more effective it is in handling contaminants and reducing the corrosive effects of acids for an extended period of time.
