95 Legend grey exhaust smoke
 

Just purchaced a 1995 Legend with 135000 miles. Car runs great but noted after engine has warmed up the exhaust emmits grey smoke and will continue while driving, It take a good 10 minutes after starting cold for it to start. I understand it is an oil burn but wondered if anyone else has seen this at this some what low milage and is there something else I should look for,
Thanks in advance

Check the spark plugs.
