The manual is wrong (are you sure it's a 1997 manual you are looking at?) - there was an addendum in 1996 showing that the actual oil capacity is 8.5 including the filter.... Gen 1 engines had the additional capacity. Then the Gen 2 oil pan was changed and capacity reduced. Then in 2000 the capacity increased to 10 quarts again... So its not you.... I'd drain at least a quart out - and recheck the level - the last thing you want is it over filled and sloshing up through the valve covers....
FYI - we looked at 3 different Owner's Manuals that we have and the 1997 manual shows 8.5 quarts. We also have 1996 manual that shows 7.5 quarts, and there is a third one (1996) upstairs that has the addendum for 8.5 quarts. There appears to have been several revisions....
