Bill's mail was of interest to me if not all. I make the following comments from discussions over 50 years of Healey operation but based on mineral oil;</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>. When I converted my race car from vegatable based Castrol R the oil company chemist advised to flush the oil system and do one or two quick changes of oil and filter. </div><div><span class="Apple-tab-span" style="white-space:pre"> </span>.Use a good quality oil, not necessarily the best or most expensive and change it more often. Remember oil is also a coolant and flushing process to absorb contaminants. Especially with cold starts and short runs where the oil does not get hot enough to vent off moisture and fuel.</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>.The base lubrication fluid that seperates metal parts is mineral oil and is the similar in the majority of oils. The auto manufacturers have demanded the addition of all sorts of additional materials to extend oil change periods and control their design limitations etc.</div><div><br></div><div>But although all oil companies product will comply with the nominated standard they may start with a different base quality crude. Some oil fields yield lovely thick honey like oil whereas other locations yield a dirty thin base and therefore the seller must add a lot more additives to meet the standard stated on the container.</div><div>Healey six design weakness is the early wear on cam lobes and followers. The cam and followers will continue to open and close valves but check whether they all have the same lift, ie the same degree of wear.</div><div><br></div><div>One other issue and thing to remember is that high oil pressure does not guarantee you are getting oil into all the small clearance areas and therefore lubrication. I dare not mention the obvious connection to the benefit of multi-grade oils.</div><div>For those followers of single grade oils how many people follow the manual and operators handbooks that talk about warm up before moving off and putting the engine/transmission under load?</div><div>An engine builder of record holding blown V8 dragster told me he uses lubricant as low as 5W multigrade</div><div><br></div><div>Basically it is all black magic</div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> WILLIAM B LAWRENCE <<a href="mailto:ynotink@msn.com">ynotink@msn.com</a>><br><a href="mailto:healeys@autox.team.net">net</a>><br><span style="font-weight:bold">Subject: </span> Re: [Healeys] FW: Oil again<br></div><div><br></div><div><style><!--

Mountains participating in the Glenwood Springs Rallye when it started and
frankly I wish I still were. However, at the risk of being called ignorant,
uninformed, commie pinko or whatever I have a little information that may be of
help in sorting out the oil confusion.
<div><br></div><div>Engine oil comes in generations as defined by the additive packages which
are blended in to tailor them for specific purposes. These generations can be
traced by the API codes which are located on the container. </div><div><br></div><div>The API code is two letters found on the label. <span style="FONT-SIZE:12pt;">The first letter is either a C, which denotes the oil is
intended for use in a compression ignition engine, or an S which denotes it is
intended for use in a spark ignition engine.</span></div><div><br></div><div>The second letter denotes the type of use intended and follows the
development of the internal combustion engine from the most primitive (A) to the
most sophisticated (I think they are at O Now). protective amounts of zinc were
dropped from the additive package at SM. Any oil before that, or say from SD
through SL, still contains zinc.</div><div><br></div><div>It may be true that zinc is not necessary for engines after the camshaft
break-in, but I prefer to be cautious on that score so I look for oil that is SL
or earlier. I'll let the more informed and adventurous members conduct that
experiment...</div><div><br></div><div>Some heavy duty oils such as Chevron Delo or Rotella are rated for both
compression ignition and for spark ignition service and will show both a C and
an S rating. In some cases those oils will still have an SM or later
rating.</div><div><br></div><div>The one oil type I have found that is reliably rated below SM is four
stroke motorcycle oil because motorcycles don't have catalysts. Typically it is
rated SF or SG. <span style="FONT-SIZE:12pt;">Since the oil has no way of
knowing it is being run in an automotive engine and my Healey doesn't know the
oil it's spewing is meant for a motorcycle I have been running Castrol 4T in
20W-50 grade quite happily.</span></div><div><br></div><div>As for the controversy part, if we start banning contentious topics we soon
won't have anything to talk about like most modern college campuses.</div><div><br></div><div>Bill Lawrence</div><div>BN1 #554<br><br><div><hr id="ecxstopSpelling">
