An oil filter reservoir includes a reservoir housing having a filter, which divides the housing into an oil inlet chamber and an oil outlet chamber. A housing inlet and a housing outlet circulate oil in and out of the reservoir housing. The filter includes a permeable wall and a bypass valve, which releases the increased oil pressure and volume in the inlet chamber during cold temperature operation. A baffle in the outlet chamber is spaced apart from the bypass valve and permits limited oil flow through the baffle. The baffle separates the outlet chamber into a reserve chamber and a bypass chamber. 1. An oil filter reservoir comprising:a reservoir housing;a filter in the housing, dividing the housing into an oil inlet chamber and an oil outlet chamber;a housing inlet in communication with the inlet chamber;a housing outlet in communication with the outlet chamber;the filter including a permeable wall and a bypass valve, the bypass valve opening in response to increased oil pressure and volume in the inlet chamber, for allowing a portion of the oil to bypass the permeable wall; anda baffle in the outlet chamber, the baffle including openings permitting limited oil flow there through, the baffle being spaced apart from the bypass valve, the baffle further separating the outlet chamber into a reserve chamber and a bypass chamber, the housing outlet and the bypass valve being in fluid communication with the bypass chamber.2. The oil filter of claim 1 , wherein the baffle includes a wall extending into the bypass chamber claim 1 , with some baffle openings being on one side of the wall claim 1 , and other baffle openings being on another side of the wall claim 1 , the wall limiting oil access to the baffle openings on the other side of the wall so that more viscous oil is encouraged to flow out of the housing outlet.3. The oil filter of claim 1 , wherein the wall has a u-shaped cross section.4. The oil filter of claim 1 , wherein the filter is secured in the reservoir ...
