so what does this calcium subject mean relative to Ecoboost... using both ESP and PUP (both off Amazon) - did I pay too much for the wrong oils when Walmart base version of M1 & PP are fine???
Guess one would alternate chemistry rotating those two ...
Besides people throwing around their own theories without any substantial evidence or data.... absolutely nothing. Use an oil that meets Ford's spec and you'll be fine. Its all speculation. How much calcium is too much, does anyone actually know? If LSPI was that big of a deal for the ecoboosts Ford probably would have created a different spec for it. There are thousands of ecoboosts run on PP and M1 with no issues.
I would opine that if it weren't an issue, ILSAC GF-6 wouldn't be developing standardized tests to establish how motor-oil chemistry needs to change to address it. Until then, there have been a few studies pointing the finger towards Calcium. Chevron Ornite, SAE, and ILSAC to name a few. To your point, not every T-GDI is affected by LSPI. In fact, i doubt the majority are. I don't know of any Ford engine platform that is.
