Abstract
An automotive engine is provided with an improved multifilter oil lubrication system. At least two filters are provided wherein the majority of the oil flow is through a primary coarse filter. At least one fine secondary filter is provided to filter the oil not going to the coarse filter. The oil from the fine filter is delivered directly to the engine. The improved system may be used with a smaller pump using less horsepower than previously possible by multifilter bypass systems. The addition of the fine filtration increases engine life.
