Just wanted to 2nd your opinion of Rotella T6. I know it has been said many times before BUT Rotella T6 is one of only a small handful of oils that are PURE synthetic and ranks at the top of the oil ladder, along with Redline, Motul, and Amsoil. There are perhaps 2 or 3 others that are nearly pure. All the others are variations of blends with Dino oil whether they are hydrocracked or otherwise. I'm certainly not saying these other oils aren't very good, because they are. They just aren't PURE synthetic. The legal definition of synthetic can get a little shakey too. I'm still running Victory's best, but will be changing to Rotella T6 on my next service. I ran Rotella and it's predecessor (long before they came out with T6) in all my BMW's for 43 years and hundreds of thousands of miles without a glitch. Ten years of Harley's before the BMW's (but that's another story) . Now I have finally seen the light and switched to Victory (XC, that is) and have not regretted it at all. Have a good ride!!!
