The Evolution of the Car Lubricant

Car engines have changed in many ways over the years. Below are a few factors that have forced the creation of better quality lubricants to keep modern cars on the road and working efficiently.

1) The Need For More Power

Smaller engines with fewer pistons have fewer gas burning chambers and are thus more fuel efficient. However, cars still need power to transport humans, handle challenging terrain and simply do their job. Car designers handle this need by creating small engines with more internal pressure to deliver power similar that delivered by larger engines.

Lubrication scientists had to come up with a way to protect these hotter-burning engines from damage caused by heat that builds up as the engine burns fuel. This heat causes materials in the lubricants to burn and cling to the engine in deposits known as varnish. This lubricant or oil has to be filtered and pumped through the engine regularly to keep the car on the road.

2) The Need For Lighter Materials

Car bodies currently contain a great deal of fiberglass and new technologies include the creation of carbon fiber body construction.

In addition to building more lightweight car bodies, car manufacturers are working to build engines from lighter materials such as aluminum. While aluminum is lighter than the steel alloys traditionally used in engine construction, keeping aluminum free of varnish deposits and protected from moisture exposure can be challenging.

3) Moisture Released When Fuels Are Burned

Moisture is released when hydrocarbons release their energy, more commonly known as igniting or burning. Inside your engine, moisture can be extremely destructive. In addition to the moisture caused by burning the fuel, you warm engine will eventually cool down and may be at risk for condensation.

Modern lubricants must contain additives that protect them from moisture contamination and help them to filter out deposits or sludge. These additives must also protect the engine from corrosion. All of these additives will have their own burn point and will fail at a particular temperature. Automotive lubricant manufacturers must work with car designers and additive makers to create lubricant blends with moisture resistance and corrosion protection.

4) Planning Ahead

New automotive designs will continue to push this development. Drivers want fuel efficient cars but don’t want to lose engine power. Environmental protection organizations guard us against excessive exposure to toxins. Automobile manufacturers want to produce cars, SUVs and trucks that the public will be able to drive trouble free.

Car engines have changed in many ways over the years. For the best results in your car, follow the lubrication schedule and the driving guidelines offered by the manufacture for long-term driving safety.
