There are a few that will work and like pacecarta said go reccomended or close viscosity for a stock engine. ...,,Personal experience has shown me that the brad penn is a very good oil, the cost is reasonable, buy a case and 2 good wix filters and your good for a year. ......... These oil matters are really over complicated needlessly and are not always based on a good internal inspection,..... I base my opinion on engines I have torn down and there internal condition which has been excellent on all critical wear surfaces with brad penn......all I have used in a performance engine the last 6 years......no need to over play this.
