A smog check inspection is performed by a station that has been licensed by the California Bureau of Automotive Repair (BAR). Depending on the situation, the owner may be required to take the vehicle to one of the following types of smog check stations: Test-only station, one that can perform the smog check test, but cannot make repairs.
Striped: Both safety and emissions testing required. In the United States, vehicle safety inspection and emissions inspection are governed by each state individually. Fifteen states have a periodic (annual or biennial) safety inspection program, while Maryland requires a safety inspection and Alabama requires a VIN inspection on sale or transfer of vehicles which were previously registered in ...
Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. [1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil ...
Since January 1, 2013, the OBD2 testing has led to an average of 10% failure rate. [26] On 1 April 2017, the $30 fee for a drive clean test was eliminated, however if failed the first time, $17.50 will be paid for subsequent tests. Vehicles manufactured before 1988 are exempt from the test. [27]
The Clean Air Act of 1963 (CAA) was passed as an extension of the Air Pollution Control Act of 1955, encouraging the federal government via the United States Public Health Service under the then-Department of Health, Education, and Welfare (HEW) to encourage research and development towards reducing pollution and working with states to establish their own emission reduction programs.
A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.

A true grease consists of an oil or other fluid lubricant that is mixed with a thickener, typically a soap, to form a solid or semisolid. [1] Greases are usually shear-thinning or pseudo-plastic fluids, which means that the viscosity of the fluid is reduced under shear stress. After sufficient force to shear the grease has been applied, the ...
