Everyone among the LSx crowd has their favorites. Castrol German 0w-40, Mobil 1, Royal Purple, and Amsoil are among the popular choices. I don't think you can go wrong with any of them personally. |
Thanks for your reply CSX. I was hoping to eliminate the subjective by trying to find independent lab tests demonstrating which one is best. Castrol Edge claims that independent lab tests put it 8 times better tham Mobil One but I'm not certain how "Independent" their tests are.
I also heard that 1-2 years ago, Mobil One changed their formula to use cheaper base materials including cracked carbon which is not as good as their original formula.
My own personal experience has been that Royal Purple is great but I've never tried Amsoil. I am about to try Castrol Edge for the first time.
Thanks in advance to anyone who can point us to good, independent data to help us make good choices on oil.
