i changed oil this weekend, used to use MOBIL 1 synthetic switched to CASTROL synthetic just to try it, now after driving i notice burned oil smell inside the car not strong but noticeble and outside when near the car , never had this when MOBIL 1 was in, now i dont believe chaning brand of oil would make this happen, any idea why this would be happening?

 

You changed the filter and got it on the exaust?

 

i dont believe so, but again i am not sure, ill check it out

 

Try sliding the "inside / outside" air selector to the left. ITs the one just under your hear control.... recirculate or not to recirculate?
