What do motor oil additives do?

Auto parts stores are jam-packed with aftermarket motor oil additives and oil treatments that promise a great number of advantages and benefits. These claims include:

Increased fuel economy

Reduced friction

Maximum horsepower

Improved engine cleanliness

To provide this additional performance, aftermarket motor oil additives use chemical components to boost the motor oil formula. Some aftermarket motor oil additive products have added ingredients like Teflon, molybdenum or graphite. Some have used chlorine, which can be highly corrosive when mixed with water.

We often get questions about if installing an oil catch can will affect the current warranties on that vehicle.

First, let's get what an oil catch can does with your vehicle. As most of us know an oil catch can filers out and catches carbon, oil, acid, and water from entering your engine. These contaminants will over time cause your engine to lose performance and gas mileage from engine coking from blow-by. Blow-by is not something new with modern engines. It has always been around. Back in the day when we had no concept of protecting the environment the "dirty" air produced by the vehicle's engine was in released into the air. All that nasty oil residue was allowed to drip out of the engine onto the roads. With the event of emission laws, the auto manufactures idea was to have all those contaminants recycled back into the engine. This solved the emission problem but made a different type of problem. Since then Auto Manufactures have changed their engines quite a bit to get better gas mileage and performance but the truth of the matter is a gas engine is going to produce blow-by. It is the nature of the beast and carbon, oil, acid, and water will always be a by-product of GDI Engines.
