My posts were at no one in particular. Yes, and you did say "some". What my comments are pointed at are statements like this:
"It's been mentioned that the high detergent washes off the ZPPD stuff."
And this:
Detergents affect the surface tension of the oil. When the engine is shut off a high detergent oil will run off surfaces quicker than a low detergent. Picture rain water running off freshly waxed paint compared to clinging like a sheet to unwashed paint."
And this:
"Joe Gibbs is another company that says the ultra-high detergent levels in Diesel oils harm the effectiveness of the ZDDP."
With no test data or source (web link) to back up their statements.
