They don't test for fuel in sample? No TBN? No TAN?Here is a analysis for GMs dexos 2 syn blend for our cars it was put in after I bought the car at 24,000 View attachment 178329 It has 5668 miles on it . I am running the Fuchs Titan Gt1 Proflex will run till 10000 miles and have it analyzed to see the difference in a blend and a synthetic.
Am I staring right at it?
