<div dir="ltr">I don't claim exhaustive knowledge about all racing oils. Valvoline VR1 is primarily made for racing, and I'd call it a specialty oil. Not something I've seen on the shelves at local auto parts stores. The most non-specialty oil I've seen is Mobil 1 15W-50, with an API classification SN, that has 1200 ppm zinc, and isn't recommended for extended use in cars with catalytic convertors. <div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jul 6, 2019 at 6:40 PM Charley Robinson <<a href="mailto:Charley38@twc.com">Charley38@twc.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<div>As classifications change, old oil formulations become
obsolete, the appropriate oil for flat tappet engines has
become pretty much the product of specialty oil companies like
Royal Purple, Driven/Joe Gibbs, Red Line, Lucas, and
