i was close to 30K on the odo and was thinking of changing from the oil the dealer uses to the synthetic mobil one but not sure the weight to use. doesnt the car equire 5/30 and some people have used a lower numbered multi like 0-20 or something like that? <_< anyone who have changed the oil to a diff weight plz let us know what is good and what might not be....
Stick with the factory weight 5w30. However going to Mobil1 cannot hurt. You could have done it sooner, much sooner.
