Just check and if it says it contains petroleum don't use it. If it doesn't contain petroleum then by all means use it. I personally use white lithium grease I got in a 10oz can off of amazon. It contains petroleum but I tested it on some o-rings and it hasn't damaged them at all in the past 3 weeks. I am still going to get some non-petroleum white lithium grease eventually.

There have also been a ton of posts on this if you search...

He's right, you could have just searched the forums for "grease" and it comes up with a ton of results.

Since the question was answered I will go off topic a bit. The search function on this forum is still not the greatest, as it filters out words that are used too often, such as "vsr". This makes people ask questions that have been answered countless times because the search wouldn't allow them to find it. It really isn't the greatest.
