AMSOIL Ea Air Filters

Motor homes are exposed to a lot of dust and dirt. Good air filtration is vital to keep abrasive particles from entering the engine and destroying precision components. The AMSOIL Ea Air Filter incorporates nanofiber technology which has been used exclusively in severe and heavy duty applications. AMSOIL EA Filters are more efficient and have greater capacity than cellulose and wet gauze filters, effectively extending engine and filter life and reducing engine wear.

AMSOIL Spin-On By-Pass Oil Filters

The AMSOIL Spin-On By-Pass Oil Filter is the ultimate in effective and convenient oil filtration. The unique spin-on by-pass cartridges are quick and easy to service. And because it is a by-pass system, the filter cleans oil thoroughly. In fact, the AMSOIL By-Pass removes virtually all harmful dirt particles from engine oil. The AMSOIL By-Pass even removes water.

AMSOIL Ea Full-Flow Engine Oil Filter

The AMSOIL Ea Oil Filters are the highest efficiency filters available to the auto/light truck market. Featuring advanced full synthetic nanofiber technology, Ea Oil Filters provide greater efficiency, capacity and durability than cellulose filters, extending engine and filter life and reducing engine wear. When used in conjunction with AMSOIL Synthetic Motor Oil in gasoline and diesel vehicles, Ea Oil Filters are recommended for up to 25,000 miles or one year, whichever comes first, in normal service or up to 15,000 miles or one year, whichever comes first, in severe service.

AMSOIL Synthetic Grease

Greased bearings and linkages endure heavy loads on RV vehicles. In addition, wheel bearings, U-joints and suspension points are extremely susceptible to the harmful effects of dirt, water and mud.

AMSOIL Greases are especially suited for all types of motor home applications. The tough synthetic formulations provide outstanding protection against friction, heat and wear, even in high stress applications. AMSOIL synthetic greases offer superior low temperature pumpability, resistance to water washout and thermal and oxidative stability.

AMSOIL Fuel Additives

AMSOIL Diesel Concentrate is a total cleaner and lubricity improver for all types of heavy and light-duty diesel engines. Formulated with Ultra Low Sulfur Diesel fuel (ULSD) in mind, Diesel Concentrate controls the problems created by EGR systems by neutralizing acids during combustion, minimizing acidic cylinder wear, reducing the rate of TBN depletion and maintaining oil quality. Cleans fuel injectors and combustion chamber for improved efficiency and better sealing and minimizes soot loading. Improves the oxidation and thermal stability of diesel fuel, improves fuel economy by up to five percent, restores horsepower and protects against water contamination. Compatible with all types of exhaust emission systems, including diesel particulate filters (DPF's). Also recommended in heating oil furnace applications.
Diesel Cold Flow Improver is recommended for low temperature applications below 40 deg. F. Effectively modifies wax crystal formation at low temperatures to depress diesel fuel pour point and improve cold flow filtration properties. Lowers the cold filter plugging point by as much as 20 deg. F and decreases the need for #1 diesel fuel diluted with kerosene. Contains jet fuel-type deicer to help prevent ice formation in fuels contaminated with water. Compatible with diesel particulate filters (DPF's).
AMSOIL Cetane Boost improves combustion efficiency to increase power in diesel engines. Raises Cetane three to seven numbers. Also improves low-temperature starting, fuel ignition quality and reliability. Treats up to 200 gallons.
AMSOIL Performance Improver is the most potent gasoline additive available today. As a concentrated detergent, it is unsurpassed in cleaning combustion chamber deposits, intake valve deposits and port fuel injector deposits. AMSOIL PI helps maintain peak engine efficiency, fuel economy, power and drivability in newer low mileage engines. In engines with accumulated deposits, testing showed AMSOIL PI provided the following clean-up benefits after only one tank of gasoline: Improves fuel mileage an average of 2.3% and up to 5.7% Reduced emissions hydrocarbons (HC) up to 15% carbon monoxide (CO) up to 26% nitrous oxides (NOx) up to 17% Restored power and performance Reduced need for costly higher octane fuel Reduced noise from carbon rap and pre-ignition Better drivability Smoother operation AMSOIL PI works as an "emissions passer." It is ideal for use prior to emissions inspections. Unsurpassed Deposit Clean-up Port Fuel Injector Deposits form after the engine has been shut down and there is no gasoline flowing through the injectors. During this "hot soak" period the injectors heat up and the gasoline remaining in the injectors degrades and forms deposits. This can happen very quickly with the use of poor quality gasoline and short trip driving. Because the clearances within the injectors are extremely tight and injectors must deliver precise amounts of "atomized" fuel, even small amounts of deposits can cause injectors to malfunction. Fuel flow is reduced and spray patterns are disrupted, decreasing engine efficiency, power and fuel economy, while increasing exhaust emissions.

Kudos for AMSOIL

Coast to Coast magazine, written for the RV market, (Nov/Dec 1999) explores extended oil drains, by-pass filtration, oil analysis and recommends AMSOIL as "the best place" to get synthetic lubricants.

"For a variety of reasons," writes Bill Farlow in his regular "Under the Hood" column in Coast to Coast, "synthetic lubricants have recently attracted a lot of attention. For one thing, synthetics have proven to be, for want of a better term, more slippery. With so much emphasis on increased miles per gallon, anything that can reduce friction and increase fuel mileage has come under serious consideration. Less has been said about the decreased wear from using synthetics."

Farlow notes that synthetic lubes have been used in military and commercial aviation for decades, due to the inability of conventional oils to operate in the temperature and pressure extremes of aircraft. "There has been little doubt that they [synthetics] offer superior lubrication and longer engine life, but are they worth the extra cost when the vehicle will be disposed of in 100,000 miles or so? The answer for most car and light truck owners has been a resounding 'no'. But suppose synthetics cost no more than conventional lubricants. Would you be interested then?"

Farlow does a great no-nonsense job of explaining the use of synthetic oils, by-pass filtration and oil analysis for safely extending oil drain intervals. "For the past 20 years or so, there's been a rumor that by using synthetic engine oil you could stretch oil changes to 25,000 miles. Many owners have played with the idea, but most get a bit chicken after a while and start worrying about their engines and go back to short changes of conventional oil. But a small group has been doing something else. They've been eliminating oil changes almost completely.

"Synthetics don't oxidize. Keep them clean, and they can be used for extremely long periods. How do you keep them clean? You can't reduce the filtration size of full-flow filters to less than 20 microns. But you can add another filtration system. It's called a bypass system, and it uses a filter that removes particles down to one micron or less . . . Synthetic engine oil can be used almost forever with such as system.

"Well, maybe. Even with the best of lubricants, some engine wear is going to occur. Also, there's always the possibility of something going wrong inside the engine. Maybe a copper bearing cracks or a small chip falls off or any of a thousand things go wrong. With conventional oil changes, these small particles are removed with the used oil, and you never know about them. With synthetics and no oil changes, they're removed by the filters, and you would still never know about them until something goes seriously wrong. Not to fear. There is an answer.

"Draw off a small sample of engine oil every 10,000 to 20,000 miles -- you set up the interval you're comfortable with -- and have it analyzed. The lab will send you back a thorough report showing the amounts of a wide variety of contaminants and a suggestion to either continue using the oil or replace it. Contrary to conventional procedure, you know what's happening inside your engine, and you never need to change oil until the lab finds a problem developing."

Farlow also mentions other synthetic lubricants. "Synthetic transmission lubricants are especially interesting because they not only decrease transmission temperatures but also withstand high temperatures much better than conventional fluids.

Does Farlow put his money where his mouth is? You bet. "I'm using AMSOIL’s 15W-40 diesel synthetic and bypass filters in my latest truck Big Red. But Big Red isn't my first truck to get the AMSOIL treatment. I've used it since 1991 with excellent results.
