Preheat oven to 350 degrees F. Grease loaf pans (can make in bundt pans but need to adjust timing). Mix oil, sugar, and eggs together in a large bowl. Mix in pumpkin puree. Stir together flour, soda, baking powder, salt, and spices. Add to pumpkin mixture and mix until just combined. Fold in nuts and raisins and spread evenly into desired baking pan. Depending on oven, bake for 45 minutes-1 hour or until done. Set aside to cool on wire racks before slicing.
