A blast from the past

I saw this on Pinterest, a 1969 Porsche 917 with a quite large oil can, thinking it was the 'Ring or Zeltwig. Since this is an oil forum, here's what I found out from Shell in Germany. It is an SAE40, mineral based synthetic oil. Guessing Porsche and Ferrari ran on it

That's pretty awesome. If you are into t-shirts, Blipshift (no connection to them) occasionally have some 917 shirts.
