Best Fuel Saving Additives

First, let’s get one thing; it is important to distinguish from oil additives developed by companies that have been tested, and others, usually by individuals without these tests and documentation. Anyone can put an additive package and a label. There are many on the market, which have no real test, though they say they do. This is where the additives have received a bad name. On the other hand, there are a number of companies that sell additives that have extensive research and development teams who tested their additive packages. For example, Lubrizol www.lubrizol.com whose incomes were over $ 4 billion for 2005 specializes in particular in the fuel additives and engine parts processing. Any person who makes that kind of volume is not selling snake oil to millions of dumb consumers-just does not happen. This is only a partial list of companies that have well documented additive products.

Indeed, the additives are used in most lubricants, because even the best synthetic base oils cannot protect vital parts, as there are additives that do all the work. Let's concentrate on the internal combustion engine to consider the need for additives. According to the American Petroleum Institute the powerful watchdog for oil companies, the temperatures and types of service in which an engine is operated vary markedly. Moderate speed on short trips or stop-and-go driving in traffic uses only a fraction of available engine power. Because the cooling systems must be able to meet the requirements of the engine cooling at high speed, they overcool May engine short trip driving. In this slight service engines and motor oils warm up slowly and often do not reach the proper operating temperature.

Under these conditions automatic chokes will provide the engine of the rich air-fuel mixture it needs to function well at cold temperatures, but this wealth will result in incomplete combustion. Soot and partially oxidized hydrocarbons subjected to oxidation in the crankcase, forming deposits of sludge and varnish. These screens May plug oil or plug oil rings, interfering with oil circulation and control, or if they cause May hydraulic valve lifters and valves to stick. Corrosive acids are formed at the origin of the wear of piston rings, cylinders, and occasionally on piston skirts. Steam from combustion condenses on cylinder walls and drains in the crankcase. Water, often in combination with acidic gases, cause May valve lifters to rust and stick. It May also create rust deposits on piston pins, rocker trees, stems and valves. Liquid fuel leak past the piston rings dilutes the lubricating oil and reduces its value. These are some of the effects of the operation of engines in cold temperatures.

In contrast legal speed limit driving and long trips and to allow the engine oil warm p properly. The choke is open, and the carburetor is feeding the cylinders with a lean, clean combustion air-fuel mixture. Therefore, little or no incomplete combustion to produce soot other residue. In these conditions, water is not a compensation issue or the dilution of engine oil in raw fuel. Additives have been developed to address these problems that most of us qualify much time for driving in severe service conditions. In addition, the API of course "Under certain conditions it is impossible to maintain a film oil between moving parts, and there is intermittent metal to metal contact between the high spots on sliding surfaces. Lubrication engineers call this boundary lubrication. In these circumstances, the burden is only partially supported by the film of oil. The oil film is broken, resulting in significant metal-metal. In this case, the friction generated between the surfaces can produce enough heat to cause two or metals in contact to melt and weld together.

why r piston pins offset?

to reduce piston slap or to keep thr thrust face of the piston angled in the bore

Actually, its both. Racing engines have more pin offset than normal engines to increase down-force on the piston, but they are not concerned with noise from "piston slap".
