It probably won't be a problem, since the dino grease is such a low
percentage, BUT, I would not recommend mixing greases. Here is why, with
regular greases, different greases are not made with the same base. And
because of that, if you mix them, then they break down very quickly.
With a synthetic grease, I don't know if there is such a thing as a
base, but the base in the Dino grease may react with the synthetic. The
suggestion to check with the synthetic supplier is a good one, but you
will want to ask them if they have experience with using synthetic as a
replacement grease.

What's it going to cost you to rebuild the unit, if the bearings sieze
later on?

However... The bearings have already been packed with dino grease and I
want to put in high-temp synthetic grease. Does anyone think the 2% dino
will adversely affect the Synthetic grease I plan on packing the unit with?
