I've seen reference to the fact that lead may read high in a UOA when Techron and certain other fuel system cleaners are used. What I haven't seen is why.
Is this some compound of lead that's in the Techron itself and reading as lead from blowby?
Is this actual bearing wear from something else in the Techron blowing by, getting in the oil and attacking lead?
My dad had a spike in lead on a UOA about a year ago that may have been a particle streak or something. He wanted to do another UOA 12-18 months later to see if it is a chronic condition or a fluke. The catch is that he's a snowbird and just spent the last 2 months burning Chevron 93. He was hoping for an accurate UOA, is the pre-mixed dose from the station going to skew a UOA or does it take higher concentrations than that? He also doesn't understand why lead is high (ie. is it actually wear or a false reading) and I can't tell him much.
