Hi all. Second oil change I've done and 6.5 quarts puts the level just above the top safe line both times. I know the stick could be wrong, but what would you do, put in 7 and have it way up on the stick or 6.5 and a correct reading? Am I better off with the chance of a half quart over or under? I'm changing on ramps so I'm also wondering if I'm not getting out the full 7. Thanks.
