Adding to what WIchix said, the 15-91 has open oil wicks. It has grease wicks in the motor area, but they are enclosed.
I also agree to oil being the correct lubricant. Somehow, I'm not sure that grease in an open area would reach the right temperature to melt and if it did, wouldn't a lot of it run off?
I pulled up the wick for the photo. It's usually not seen.
