I last changed my oil just over a year ago. I used castrol, don't remember what grade, and the car slightly smoked. So i changed for mobil 1 SOMETHING? and it ran great with no smoke and hardly any ticking. I don't remember what mobil grade i used. So, what Mobil oil should i use. 66 289 4 bbl rebuild in 2005 with no mods. Thank you
