Number of engines?There is a reason.
I will try to find the quote when I have time, but Pennzoil mentioned it before (in 2014ish) on this site and others, that some of their detergent (or could be dispersant, can't remember 100%) additives give the used oil a red tint after a certain amount of operating cycles.I figure I could post this question here and save me an oil analysis fee. And it's not a question that is gonna change my life or anything.
I am merely curious. That is all.
What would you think would make used engine oil at a 3000-5000 mile OCI have a red tint? It's actually quite attractive but no other oil
that I have ever used turns this color. I am not bashing the oil. I thought it was my engines issue but it did it on multiple cars. I experimented with
another oil and it does not tint red. Could there be some special additive? Some secret ingredient?
When I say red tint, the oil looks like used oil in the drain pan. It's when it fans out during the drain or when you swirl the drain pan that the red tint
shows up. Or on your paper towels during clean up.
I enjoy sarcasm so have at it
