what's up everyone, before i go out with my car when it's cold i make it idle till it's a little hot. if i do that i don't see any smoke but if i'm done driving i come home make the car idle for let's say 5 min or so, when i do that then there comes white smoke of the exhaust, today i serviced my car i put 10w-40 in the engine and now it smokes more, previously i drove on 10w-30. can anyone tell me what this is?
