Motor Oil Info

Equipment manufacturers and motor builders have redesigned two-cycle motors to reduce emissions and increase fuel economy. These changes have increased operating temperatures, reduced oil consumption and incorporated direct fuel injection and exhaust power valves. AMSOIL 2-Cycle Oils are designed to maximize performance in all types of engine designs and are optimized for select applications.

Even though AMSOIL 2-Cycle Oils have been optimized for specific applications, they are multi-functional and recommended for use in many areas. Saber Professional 100:1 mix is a excellent choice for chain saws, lawn mowers, weedeaters, mopeds, scooters and go-carts, and it’s smokeless, and it’s cost-effective compared to oils mixed at 50:1 or richer. Lean mix ratio helps prevent plug fouling and exhaust port deposits. One mix ratio for everything eliminates confusion. At 100:1 produce lower emissions than oils mixed at 50:1.

Wear particles can scour away piston liners, cam lobes, piston rings and other engine parts, reducing combustion efficiency and causing the engine to burn more fuel to produce maximum horsepower. Wear in the valve train can disrupt timing and valve movement, while ring, piston and liner wear reduces volumetric compression and contributes to blow-by.

By-pass Filtration that removes particles smaller than 10 microns directly correlates to reduced engine wear and optimum efficiency. In the article “Clean Oil Reduces Engine Fuel Consumption” on Machinery Lubrication magazine’s website, the author surveys a number of studies that confirm this. Studied over 50,000 miles of service, buses fitted with Cummins six cylinder 8.3 liter turbocharged engines achieved 2 to3 percent gains in fuel efficiency while operating with six-micron by-pass filtration. A second study of a six-cylinder diesel engine saw dramatic improvements after installing a by-pass filter rated 75 percent efficient at six microns: oil contamination dropped 98 percent, friction decreased 2.9 percent and fuel economy increased 5 percent.

When an engine is started or running abnormally, some unburned fuel in liquid form is deposited on cylinder walls. That means raw fuel leaks past the rings into the crankcase, where it reduces the viscosity of the oil. Dilution lowers the film strength of the oil and increases oil consumption. Usually this is a minor problem when engine operation is at high-speed or high-temperatures, but it can be a problem in vehicles consistently used for short-trip driving.

While all of the processes by which a motor oil is contaminated are not fully defined, the use of high-quality motor oils such as AMSOIL Synthetic Motor Oils allows motorists continued protection of their engines along with extended drain intervals, all while limiting the contaminants in the oil and prolonging engine life.

Motor oil becomes unfit for service after a period of use. Two main reasons for this are the accumulation of contaminants in the oil and chemical changes (additive depletion and oxidation) in the oil itself. These factors cause deterioration of the oil and prevent it from doing the job of lubricating amd cooling engine parts.

Design limitations of air cleaners, some oil fill caps, and crankcase ventilation systems allow some dust and dirt to enter the engine. Leaks in the intake system also permit unfiltered air to enter the engine. However, proper maintenance of the engine and its accessories can minimize the amount of contaminants entering the lubrication system and extend engine life.

AMSOIL synthetic motor oils allows motorists continued protection of their engines along with extended drain intervals, all while limiting the contaminants in the oil and prolonging engine life.

Example, a four-cylinder engine could have two plugged injectors, while the other two may only be mildly plugged or not plugged at all. The oxygen sensor indicates to the computer that the engine is not receiving enough fuel, so it increases the fuel supply to all four cylinders. Now the two injectors that weren’t plugged are providing more fuel than necessary. As a result, it creates a situation where two cylinders are running rich and the other two are running lean. Removing fuel injector deposits allows the engine to operate as it was designed, improving fuel economy, lowering emissions and contributing to improved drivability and increased power.

Whether deposits have built up over a relatively low number of miles, or they have accumulated over 100,000 miles, P.i. fuel additive effectively removes them. Because fuel injector deposits and the associated performance issues usually build up slowly over time, motorists often attribute the decreased performance to the increased age of the vehicle. When the deposits are removed, the performance improvement is immediate and significant.

Fuel injectors provide drivers with more precise control of fuel, improving fuel efficiency and minimizing emissions. However, in order to work efficiently, they must be kept clean. Because performance suffers as fuel injectors become dirty, the U.S. goverment mandated in the mid-1990s that all gasoline sold in the U.S. be formulated with a lowest additive concentration (LAC) level of detergent additives to help keep engines clean and emissions under control. However, it takes a very low level of additive to pass the tests, and most gasoline on the market contains as little as 123 parts per million (ppm) of additive.

The low levels of detergent additives in modern gasoline allow deposits to build up on critical fuel system components, and most motorists are unaware of how dirty the insides of their engines are. AMSOIL P.i. Improver is an effective one-tank, total fuel system cleaner. More potent than other fuel additives on the market, P.i. effectively cleans everything the fuel touches, including fuel injectors, intake valves and combustion chambers, in only one single tank of gasoline, removing the deposits that have built up over thousands of miles. Removing engine deposits with P.i. effectively improves fuel economy, reduces emissions, restores power, performance and acceleration, reduces octane requirements, increases engine life and reduces maintenance costs.

AMSOIL Synthetic Motor Oils and Lubricants are manufactured from top quality synthetic base stocks and performance additives according to a stringent quality control protocol in computer-controlled AMSOIL manufacturing facilities. AMSOIL synthetic lubricants may be counted on to deliver the same top-quality performance and protection every time they are used, no matter where in the world they are purchased.

AMSOIL synthetic lubricants’ heat stability and friction reducing ability keep wear rates low, which helps increase the time to first teardown, increases the interval between teardowns and increases overall equipment life.

Today, synthetic motor oils and lubricants have become mainstream. Modern vehicles and equipment demand the protection and performance that only a synthetic can deliver. Synthetic Lubricant sales are especially strong in Europe, where they account for approximately one third of lubricant sales and are used as factory-fill lubricants in one third of new vehicles sold there. Interest in the U.S. has also spiked in recent years.

The vehicles of the future will continue to have smaller engines, stricter emissions requirements, higher performance characteristics and better fuel economy. According to Pathmaster Marketing, Synthetic lubricants will show continued growth in the years ahead as the market continues to demand higher-performing lubricants. They’re not just talking about trucks and cars on the road, but also gearboxes, industrial hydraulics and other equipment.

Sludge Formation is caused by oil being subjected to abnormal operating conditions such as high heat, excessive blow-by gasses, glycol contamination or poor crankcase ventilation. Sludge formation, if severe enough, can block the oil passages and oil pump pick up screen, resulting in oil starvation.

AMSOIL Synthetic Motor Oils have better oxidation resistance, detergency and dispersancy than conventional petroleum oils, and they do a better job of resisting sludge. However, they will not stop sludge formation under abnormal engine operating conditions. The use of synthetic oil for the best possible engine protection is endorsed by Consumer Reports.
