Here is the reply from Christopher from Zico concerning gear and shredder blade lubricant:

You can use a lithium grease for the gears and axles of the shredder, as long as it's away from the blades. The blades don't have any grease, but you can dab a bit of vegetable oil on a leaf every now and then to keep things moving.

[/FONT]So any lithium will do - since the gears are isolated from the shredder blades it doesn't matter. I'm going to stick with a red lithium since that is what the factory used, either the Lucus or LMX, LMX seems to have better reviews online so I might order that from Amazon.
I like the recommendation to put a dab of vegetable oil on a leaf to lubricate the blades now and again but I know from experience - only use a tiny bit and not too frequently. And it goes without saying, that won't be a smokable (?) leaf - maybe even the next couple leafs if it has any traces of veggie oil.
I used vegetable oil instead of shredder oil or something light like sewing machine oil on a paper shredder many moons ago, only did it every couple hours of shred time but used too much each time and eventually the blades got all gummed up. It was a cheap shredder so it didn't matter much but it was a teaching moment.
