HELP! My fiance's very kindly offered to do a basic service on my Palio. He's just battling to get the sump plug open!!! Apparently it's quite a common problem. ANY SUGEGSTIONS? Does the righty tighty lefty lucy rule apply no matter which angle you're taking it from? Sounds daft I know, but when you're battling for hours trying to turn a little plug, one's basic knowledge of physics comes into question!!! Will putting spraying some oil on it help, or will that just make the allan key slip? I could just take it off to a garage but he's got so far...! Any suggestions would be greatly appreciated! Thanks!
