I use Raggtop, as do a lot of other folks here. General consensus seems to be that it is the best product to use.

As to the oil, don't worry about weight, not important. If you get to know the folks at your local garage you can get them to save the stuff they drain out of other cars for you. Just pour it through some cheesecloth to filter out the chunks before you put it in your engine.
You really want me to tell you where you can put your jack?
