1. A surface cooler, comprising: an oil layer, through which oil flows;a separating plate disposed in heat transfer communication with the oil; andfins extending into an air flow pathway and being disposed in heat transfer communication with the separating plate, the fins being arranged with varied configurations at each of two or more sections sequentially defined along a predominant direction of air flow along the air flow pathway,the two or more sections comprising a leading section, a rear section and an intermediate section interposed between the leading and rear sections,the fins at the leading and rear sections comprising sloped leading and trailing ends, respectively, the sloped leading and trailing ends including slopes transverse to a plane of the separating plate that begin to protrude from and terminate at the plane of the separating plate, respectively, wherein the fins at the leading section are thicker than the fins at the rear section. 2. The surface cooler according to claim 1, wherein the fins at a rearward portion of the leading section comprise a flat top surface. 3. The surface cooler according to claim 1, wherein the fins at the intermediate section are formed with a repeating pattern. 4. The surface cooler according to claim 1, wherein fins at the intermediate section have thermally efficient shapes. 5. The surface cooler according to claim 1, wherein the fins at the intermediate section have high thermal performance shapes. 6. The surface cooler according to claim 1, wherein the fins at the rear section comprise a sloped rear end. 7. The surface cooler according to claim 6, wherein the fins at a forward portion of the rear section comprise a flat top surface. 8. A surface cooler, comprising: an oil layer, through which oil flows;a separating plate disposed in heat transfer communication with the oil; andfins extending into an air flow pathway and being disposed in heat transfer communication with the separating plate, the fins being arranged with varied configurations at each of two or more sections sequentially defined along a predominant direction of air flow along the air flow pathway,wherein the two or more sections comprise a leading section, a rear section and an intermediate section interposed between the leading and rear sections, andwherein the fins at the leading section are thicker than the fins at the rear section. 9. The surface cooler according to claim 1, wherein the fins at the leading and rear sections are substantially straight. 10. The surface cooler according to claim 1, wherein the fins are formed to define first and second transition zones between the leading and intermediate sections and between the intermediate and rear sections. 11. The surface cooler according to claim 10, wherein the fins are formed in a predefined pattern at the first and second transition zones. 12. A surface cooler, comprising: an oil layer, through which oil flows;a separating plate disposed in heat transfer communication with the oil; andfins extending into an air flow pathway and being disposed in heat transfer communication with the separating plate,a leading section of the fins having a first thickness, being substantially straight and being arranged with a sloped leading end,a rear section of the fins having a second thickness, which is thinner than the first thickness, being substantially straight and being arranged with a sloped rear end, andan intermediate section of the fins being arranged between the leading and rear sections with a repeating pattern of high thermal performance shapes. 13. The surface cooler according to claim 12, wherein the fins at the leading section comprise a flat top surface rearward of the leading end and the fins at the rear section comprise a flat top surface forward of the rear end.
