I have been using 20-50 VR1 in my 80 MGBLE but I see from the website that you provided that it should not be used in cars with catalytic converters which my 80  MGB has. In fact, all of the recommended oils with zddp should not be used in cars with catalytic converters  so what should those of us with RBBs use? we need the zddp but not the added  aggravation  of concern about our cats?

Maybe you haven't looked hard enough.  I bought two quarts of 20W50 VR1 yesterday at my local Autozone.  The other local stores carry it too.  The first bullet on the back label calls it "High Performance/Racing Oil". Here's a blurb from Valvoline's website: https://sharena21.springcm.com/Public/Document/18452/18bdee61-0a7e-e711-9c10-ac162d889bd3/a61538b4-0cbd-e711-9c12-ac162d889bd1

I've been using  20W50 VR1 in my '69 MGB for the last 5 years or so.  I use synthetics in my newer cars.

  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.

    Sorry, I don't agree unless you see Valvoline as a specialty motor oil supplier.

      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 Collectors Choice (Moss).

        I've been reading up on it to refresh my memory.  A lot of folks just take other peoples' word for it.

            Right, but there are other brands. I use Mobil1 15W50. Others use Royal Purple, Joe Gibbs, Kendall or AMSoil brands.
