I just picked up 0w40 at Wally world for $22 and some change.  Great price after paying $34-$36 at Advance for the same 5 quart jug.  That is all I have ever run in my 99'.  
Can anyone show me what benefits there are for changing from the manufactures recommended weight and using a heavier weight oil like 10w40?
