dass,
Did you get to the .pdf document on Pennzoil's site? If so, and if you got errors when trying to view the .pdf document, try going to Adobe's site here and getting the latest version of Acrobat Reader. Problems reading .pdf files usually result from the file being created with a newer version of Acrobat than the version of your reader.
I'm attaching a jpeg conversion of the .pdf file. Hope it isn't to "fuzzy" too read well.
