KUALA LUMPUR, May 20 (Reuters) - Malaysian palm oil futures edged lower on Wednesday, after three consecutive sessions of gains, weighed down by weaker crude oil prices and supported by firmer rival edible oils.

The benchmark palm oil contract FCPOc3 for August delivery on the Bursa Malaysia Derivatives Exchange slid 26 ringgit, or 0.57%, to 4,559 ringgit ($1,146.63) a metric ton in early trade.
