Engine Lubrication System Technology

    There are basically two types of oil systems in vehicles:wet sump and dry sump.

    Most cars use a wet sump system. That means the oil pan is at the bottom of theengine, and the oil is stored there. The advantage of a wet sump system is its simplicity.The oil is close to where it will be used; there aren't too many parts to engineer or repair,and it's relatively cheap to build into a car.

    Some cars,especially high-performance cars,use a dry sump system. That means thesump isn't underneath the engine一in fact,it can be located anywhere within the enginecompartment.A.dry sump system gets you a couple of bonuses:First, it means the enginecan sit a little lower, which gives the car a lower center of gravity and improves stability atspeed.  Second,it keeps extra oil from soaking the crankshaft,which can lowerhorsepower. And,since the sump can be located anywhere, it can also be any size andshape.
