That was not my intention. And I didn't state that it was some trusted data. I was just posting that as a reference, to show "xgmad" what myself and "ofelas" are referring to in posts #21 and #22, as it didn't seem that he caught that reference for what it was. (Sorry xgmad if I'm wrong.)
I have like 50 gallons of this SN rated Chevron 400 XLE 10W30 diesel syn-blend (AZ special "private" clearance $5 a gallon) and have run it in my Suburban/Silverado 4K mile OCI's to see how they do with VERY good results !!
