Are European GDI and TGDI engines somehow immune from LSPI? Or do they have ways of addressing beyond changing the oil formulation? Just about every Euro spec’d oil I’ve seen (including, LL-01, LL-04, 229.5, 229.51, A40, C30, etc.) are high Ca (2,000-2,400 for A3/B4 and around 1,600 for C3) with essentially no Mg. Even the more recent specs don’t seem concerned with calcium doses. It makes me wonder how much changing the calcium content really can impact LSPI. Thoughts? Ever seen a low-Ca C3 oil?
