HPL, Redline and Schaeffers

[Mainia]

I currently have Motorcraft syn blend 5W30 and a quart of HPL EC in my 3.7 F150 that I posted about recently. I do plan on running HPL from here on out but this is Bitog and just for fun Im considering doing a 8k run each of HPL 5W30, Redline 5W30 and Schaeffers 5W30 and see how they compare with a UOA. Are these oils pretty comparable to each other? I like that Redline 5W30 has a film strength equal to a 40 grade.

Redline Performance at least in the past before reformulation of some of their performance series oils, caused a spike in lead do to opinions of add pack incompatibility. Happened to me, and I was working with Polaris Labs, and when I kept running it. my lead dropped to zero after 2 oil changes running the same Redline 5W-30 Euro. That oi lhas been reformulated since then, so who knows if that issue is still valid.

That's likely just chelation, the removal of oxidized top layers of soft metals. (harmless) It's a common side effect of using a high ester oil in an application that hasn't seen ester prior.
