<p class="MsoNormal" style="margin-bottom: 12.0pt; line-height: normal;"><span style="font-size: 14.0pt; mso-bidi-font-size: 12.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Arial; color: black;">Hi, </span></p>
<p class="MsoNormal" style="margin-bottom: .0001pt; line-height: normal;"><span style="font-size: 14.0pt; mso-bidi-font-size: 12.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Arial; color: black;">Thanks all.<span style="mso-spacerun: yes;"> </span>As is usual there is a lot of good discourse and experience shared by the list. <span style="mso-spacerun: yes;"> </span>What triggered my question on oil and oil additives was the observation of a bottle of Red Line 10W40 image that did not display the usual statement that it contains ZDDP. <span style="mso-spacerun: yes;"> </span>For decades I have used that oil as it carries proper oil pressure, suites the climate, etc. <span style="mso-spacerun: yes;"> </span>However, if Red Line stopped including ZDDP, I would find another oil. <span style="mso-spacerun: yes;"> </span>I also recalled that some time back, Bob Spidell having to find a new outlet for Valvoline 20W50 as it seemed that it no longer cleared some California rule changes. <span style="mso-spacerun: yes;"> </span>I wondered it this happened to Red Line.</span></p>
<p class="MsoNormal" style="margin-bottom: .0001pt; line-height: normal;"><span style="font-size: 14.0pt; mso-bidi-font-size: 12.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman';"> </span></p>
<p class="MsoNormal" style="margin-bottom: .0001pt; line-height: normal;"><span style="font-size: 14.0pt; mso-bidi-font-size: 12.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Arial; color: black;">So, I sent off an inquiry to Red Line and not getting a rapid response sent one to our Healey group. <span style="mso-spacerun: yes;"> </span>The Healey group was much faster to respond. <span style="mso-spacerun: yes;"> </span>While most business are slowed down by COVID-19, a Red Line response did come. <span style="mso-spacerun: yes;"> </span>The assurance is that Red Line Motor Oil 10W40 (SKU 11404) contains good ZDDP levels, plenty for an Austin Healey's flat tappet cam and lifters; 1225ppm zinc and more importantly 1375ppm phosphorus.<br style="mso-special-character: line-break;"><br style="mso-special-character: line-break;"></span></p>
<p class="MsoNormal" style="margin-bottom: .0001pt; line-height: normal;"><span style="font-size: 14.0pt; mso-bidi-font-size: 12.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman';">As to their break in additive, their Web site indicates that a half bottle is enough to add to a conventional oil.<span style="mso-spacerun: yes;"> </span>It also has bit of sulfur, 16.6 grams.<span style="mso-spacerun: yes;"> </span>I have to wonder if adding it to their 10W40 could result in too much.<span style="mso-spacerun: yes;"> </span>I am just not inclined to experiment.</span></p>
<p class="MsoNormal" style="margin-bottom: .0001pt; line-height: normal;"><span style="font-size: 14.0pt; mso-bidi-font-size: 12.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman';"> </span></p>
<p class="MsoNormal" style="margin-bottom: .0001pt; line-height: normal;"><span style="font-size: 14.0pt; mso-bidi-font-size: 12.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Arial; color: black;">The 3000’s owner’s manual only mentions 30 weight oil, even for tropical heat.<span style="mso-spacerun: yes;"> </span>However, the “Work shop Manual” (the Green Book) has a much more expansive table that promotes a lot of weights depending on the manufacturer.<span style="mso-spacerun: yes;"> </span>The aspect that modern oils are a bit different than those available when the book came out adds a bit more uncertainty.<span style="mso-spacerun: yes;"> </span></span></p>

<p class="MsoNormal" style="margin-bottom: .0001pt; line-height: normal;"><span style="font-size: 14.0pt; mso-bidi-font-size: 12.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Arial; color: black;">I am confident using the 10W40.<span style="mso-spacerun: yes;"> </span>I used 10W50 in my Triumph, but it was an air-cooled engine and was REAL hard to start in freezing weather.<span style="mso-spacerun: yes;"> </span>There were also a lot of reputable recommendations that led me to Red Line’s 10W40.<span style="mso-spacerun: yes;"> </span>The oil pressure is proper, so I don’t see an upside for me to use a heavier oil.</span></p>
