Does not seem like very much Phosphorus, wt % 0.085 Zinc, wt % 0.094 Larry Jabin San Francisco From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of lettercars@xxxxxxx Sent: Sunday, November 14, 2010 5:27 AM To: paulholm@xxxxxxxxxxxxx; mckanical-marvels@xxxxxxxxxxxxxx Cc: chrysler300@xxxxxxxxxxxxxxx Subject: Re: [Chrysler300] Oil All: I have a simple question for those who know. Do diesel engines use flat tappets or roller type? Seems like the answer to that would help decide the correct oil for us. Personally, I have used Castrol diesel oil in the 300F since the first change. So far, so good with six meets under its tires. 300ly, Gil Cunningham Yet another perfect day in Tally-town, FL In a message dated 11/13/2010 8:22:25 P.M.
