Versaabbo,
Read the motor oil bible (link above). Skip the prosteletizing intro if you want. Or at lease look at the rating tables in the back. The tables give you the specifics of each product for comparison.
The XL7500 is Top-o-the-line stuff. However the S3000 has a higher TBN number so it might last longer. However as I said above, unless you're willing to really streatch out your drain interval, you're not going to come close to wearing this stuff out. S'probably better to go with the higher VI of XL7500.
EDIT: I just looked at the AMSOil site and I can't find the 7500 that's quoted in the MOB. Maybe they don't make that anymore, maybe they just lowered the ratings. The MOB has those specs dated Apr-03 so??
Looking at what's listed there today, the ASL is probably better stuff. And they charge a $ more per QT. But the XLF is probably fine. Both have very good ratings. The ASL has a higher TBN and will neutralize more acid, but that might be moot in a small engine with a drain interval of 7500.
