A friend of mine gave me 6 quarts of this stuff in 10W-30 (said he didn't need it. Didn't ask him why). Anyway, I'm about due for an oil change on my 97 Dodge Ram 1500 5.9L V8 and I considered using this stuff rather than just letting it go to waste. I know its SL rated with a high zinc content and some people fear it will "ruin" their catalytic converters. I'm not worried about that. I was just curious what the add pack is like. Obviously this isn't made to clean up sludge as some oils are marketed, but is the add pack more akin to something like VWB? What kind of OCI would be appropriate for this oil? I asked on another forum and someone mentioned not going past 1000 miles which seems a little silly.
