Oil Coolers

For those that race their Escorts, what are your feelings towards oil coolers. Are they really necessary on cars that are doing maximum 10 lap events? We're talking 2L Pinto's here.
My Grp C car originally did, but it will never do 140+ laps around Bathurst again so I'm questioning whether it needs it for sprint events.
