Here's the issue. I've performed a UOA at 40229 miles(9378 on oil)and at 56177(8385 miles on oil). In both cases Blackstone reported that everything was close to universal averages except for lead, which was 22 ppm in both samples(the universal average is 6 ppm). TBN was low on both samples as well; 1.4 for the first test and 0.4 for the second.
So... Any thoughts, questions, or rude remarks?
