What is the deal with the green vs. silver caps?
I noticed the dexos1 logo is different on each.
No "gen2" on either of them. It does appear the green cap is relatively new.
Old shelf stock at Walmart for the silver cap one?
On the back of the bottles, if the dexos1 license begins with GB... then its the old generation 1, otherwise Gen2.
I think that stuff has been low Ca, high Mg for a few years, so probably fine for LSPI anyway. I dunno about the timing chain wear test though!!
