Hey MZ-Bird - Have you considered trying Pennzoil Synthetics? We are currently recruiting for our 2016 Pennzoil Used Oil Analysis program, and you seem like a great candidate. You may have seen it on BITOG last year, but through the program, we'll send you a sample of our motor oil along with testing supplies for a complimentary UOA from Blackstone. That way, you can compare our oil to the competitive motor oil you're using. If you're interested, please send us a private message, and we can fill you in on additional details. Looking forward to your response! - Gena & The Pennzoil Team
