Are you purposely being obtuse or is that a serious question?
In case you missed it, the OP said he's read a lot of positive reviews on the product. So I'm offering up my experience with the product - nothing more, nothing less. I even stated the product may indeed work for some but for me it didn't. And if I were seeking strictly the opinions of 68 VW Bus owners about the product, I'd post the question in a VW owners group or I'd at least state that in my post.
And while I don't have a '68 Bus, I think it's totally relevant to the discussion the effect the product had on my oil. Had I read a testimonial like that prior to purchasing the product, I probably wouldn't have. It was as I stated, a costly mistake.
I did not think such a small ammount of liquid could actually change the viscosity of the host oil enough to trigger a low pressure situation.
I dont think the ATP caused your CEL.
More likely the strong solvent loosened or liquefied a piece of whatever muck was in the screen and it end up in the oil pressure sending unit hole temporarily giving a false low reading.
