It is also unwise to redline a new car that is still getting the engine broken in, most new cars come from the factory with inferior oil until the first service because manufacturers know it will need to be replaced very soon anyway.
Older cars equipped with carburetors would often have two stages, the first set to lower or regular acceleration and the second opening either at full throttle or higher load, dumping as much fuel as possible. Modern cars on the other hand will have different engine maps built into the ECU, often marketed as economy and sport mode, this is far more precise than an old carb engine just sending more fuel into the combustion chamber. These engine maps will be holistic, with every parameter taken into account from air temperature, to the rev limit setting. It is important to check functionality for both, whether it is the old second stage of a carb or that your ECU unlocks the horsepower your car was designed to make.
Not only will taking your engine to the redline test every component, but it will also make sure that when you actually really need more power it will make that power reliably and not let you down with something as minor as a clogged jet or injector.
Over time every single combustion engine will suffer from this issue, in modern vehicles with more precise engineering, this will be felt more as the loss of efficiency will quickly lead to a loss of power.
It is easy to reduce the effect though, firstly using the right gas and oil is crucial to the performance of the engine. There is a multitude of reasons manufacturers will recommend certain oils, obviously as soon as a brand is mentioned it is marketing. However, sticking to the right grade of oil and for modern engines and using only premium gas will greatly reduce the buildup.
Redlining your engine should not be done regularly, nor should it ever be done while an engine is still cold, but doing it occasionally helps get the engine beyond the normal operating temperature. This will burn off a lot of the unwanted carbon living inside the engine, effectively cleaning it out.
All engines are different, some will be more efficient than others. Older, less efficient engines will need this the most but will also likely feel the adverse effects the least, until it is too late and then instead of cleaning a component you will need to repair or replace the component.
Make no mistake, it can be a bad thing if left unchecked or if it occurs in the engine, but most of the time it is a good thing. The sludge that forms in an oil pan is essentially debris collected by the oil and pulled or filtered away from all the engine components. This will mostly be made of tiny iron fillings from the engine, normal wear, some of it will be debris from the fuel if the owner uses lower octane gas or gas that is stored in old tanks, and the rest will be carbon.
"'Redlining' is the discriminatory practice by banks or other financial institutions of denying or avoiding providing credit services to consumers because of the racial or ethnic demographics of the neighborhood in which the consumer lives."
Redlining gets its name from "residential security" maps drawn by agents of the Home Owners Loan Corporation, a federal agency, between 1933 and 1940. On these maps neighborhoods would be grouped into four color-coded categories, with highly desirable neighborhoods shaded green and the least desirable neighborhoods shaded red.
HOLC agents very often made decisions on neighborhoods based on race, class, and ethnic composition. Financial institutions would use this information to decide who was a good lending risk; people from the "redlined" neighborhoods were considered too risky to loan to simply because of where they lived.
In the map to the right, created in 1937 by HOLC and available online through Mapping Inequality: Redlining in New Deal America, the red neighborhoods were home to the city's Black community and recent immigrants to the United States--mainly Italian and Polish.
Mapping Inequality: Redlining in New Deal America is an interactive map created through a collaboration between four universities. Warning: most maps include comments about each neighborhood from HOLC agents--many using language we would find offensive and racist today.
Zoning is how cities and towns all across the United States regulate land use. In Connecticut, every city, town, and borough has their own regulations. Some activists are now claiming that zoning laws in wealthier towns are deliberately exclusionary, and that requirements like minimum lot size and prohibitions on multi-family housing discriminate against people of color.
