Im sure it would be fine. I don't use the AE grease either. The tube that came with my kit is still unopened. I have been using a big tub of gorilla snot grease I bought a couple years back. I like it because its super sticky and it stacks to gears and doesn't fling off like most grease does. I just use it on everything since its always handy sitting open on my bench. Anything is better than nothing, so use what ya got. If its a pretty thick grease I'm sure it will be fine.
