Is anyone developing lifetime engine oil

BMW, Mercedes, Audi, and Volkswagen all sell lifetime transmission fluids and guarantee that the original fluid will not fail for the entire life of the transmission. Let’s take, for instance, a 2009 BMW. Pick your model, and it makes no difference. All new BMWs come with an 8-year/50,000-mile (80,467 km) warranty that includes oil changes. However, a transmission fluid change is not listed anywhere on the service schedule.

Owners of high-end vehicles need to check and change their engine oil regularly, but they don’t have to change their transmission fluid. You would think that lifetime engine oil is the next step. Wrong. It’s a different ballgame with engine oil.

Engine oil has three main functions and is not like a transmission fluid. Oil lubricates the engine’s internal components, such as the crankshaft, bearings, camshafts, and lifters. Most people know this well. The primary functions of oil are cooling and cleaning. Oil cools the internal engine components and keeps temperatures under control, while detergents or additives clean carbon buildup and dirt from the crankcase via the combustion chamber. Transmission fluid cools and lubricates, but it is completely sealed. The transmission doesn’t need to deal with any outside elements, such as those entering the intake or combustion chamber. Transmissions don’t generate the same heat as other types.

Let’s look at oil from a different perspective and see if it can create lifetime liquid gold.

Oil: Your Lifeline

Unlike transmission, power steering or brake fluid, engine oil has the additional responsibility of cleaning the engine from soot and dirt. The transmission has a sealed system that prevents dirt and debris from entering its interior. A motor, however, is open to dirt, pollen and water. Although gaskets, piston rings and piston rings are very good at keeping the engine cycles separate, exhaust, soot, and dirt will eventually find their way into the crankcase.

Engine oil has a limited life span because cleaning is one of its main duties every time it fires up. You may have ever wondered what makes engine oil black. It’s because it contains dirt and soot. All that dirt and soot can be removed from engine oil by using additives or detergents. Oil can be thought of as blood within the human body. Oil cools, lubricates, and removes dirt. Blood transports oxygen throughout the body to all organs. All the dirt and grime in oil give you that black colour. Some synthetic oils can still work even if they are very dirty. This is why you see the black colour. However, there is a limit to how cleanable it can be. This is why lifetime engine oil is not practical.

Another factor is heat. Engines can reach temperatures of up to 275 degrees Fahrenheit (135.5 degrees Celsius). High temperatures can alter the chemical composition of the oil. Synthetic oils are better at handling heat, while conventional mineral oil oils can break down at high temperatures, losing their original chemical composition. According to traditional wisdom, your engine oil should be changed every 3,000 miles (4 828 km). You can last much longer between oil changes with synthetic oil. BMW recommends that the MINI Cooper receive an oil change once every 15,000 miles (24.140 km).

Synthetic oil is the closest to life-engine oil at this time. Synthetic oil is different from refined oil or mineral oil in many ways, including the cost. Synthetic oil will cost you three to four times as much. Synthetic oil will prolong the time between oil changes. Pure Power Inc. sells a lifetime washable oil filter for $199. That’s roughly the price of 40 disposable filters. However, this does not solve the filter part of the equation. You must change your oil regularly, at least for the moment. Your vehicle’s engine is dependent on oil. Oil is your engine’s lifeline.
