It may be old school, but the price was right. Free!

I have the lithium grease on hand for working on motocross race bikes. We use it quite often for small parts that need lubed. A good silicone spray or lube will work also. I wouldn't even consider a heavy oil or grease for my pedal. Attracts dust and dirt into the bearings, which will wear on high hat and pedal parts real fast.

I'm sure it will be a while before I have to do my bass drum pedal. I've had a DW 9000 pedal for a while and it's never had to be greased. Check on the warranty period for your DW pedal. I'm not sure, but it may be 5 years. They may fix that squeek for free.
