Years ago, most folks (me included) would probably have told you to stay with CastrolGTX, it was generally considered the number one oil, and Fram filters were also considered number one as well.....but now we have the internet....and we have learned about....THE FORCE........
just had to do that...
I think most folks at this time that will advocate using standard petroleum oil will probably choose the Chevron (or Havoline now that the two have merged), but it is still a close call for most of us on here. Oil manufacturing technology and marketing have gotten to the point now where:
1) all "SL" rated oil is good
2) it is rather confusing as to who makes what oils...
personally, I go with Havoline/Chevron
I also use the Walmart filters with 3k changes
see ya
