Oil Change time?? Which oil????
 

Guys,


Im going to change the oil tomorrow. I would like to know if i should stay with castrol gtx 10w30 conventional oil or go with full synthetic mobil 1 10w30...

My car is driven only on street and never raced. Its a weekend car that is all bone stock. Also, its going to get warm here in socali, should i change viscosity to 20w50?

I read the posts on synthetic but still confused....

We do not allow any more oil debates. There are countless threads....the summary is:

*synthetic is not harmful for rotaries and is better for the turbos
*synthetic costs more and benefits are not proven
*I don't know of anyone who's had a motor failure due to the oil they were running.....
