Just google
oil comparision. There have been lots of tests. The syntec is better than the traditional but still not great. Also there is a thread on CC about using Rotella T with links to the sources. And actually, i stand corrected. Pennzoil was the worst. Then Castrol.
I use valvoline VR1 20w50 in my race car and it hasn't failed me. of course it is changed about every 4 nights at the longest.
