Hopefully that doesn't mean they are closing it out. I can still get it from the local Oriellys, but they only stock a few jugs at a time, sometimes they have 20-5o, sometimes 10-40, rarely both at the same time
I use conventional VR-1 10W30 and I've only seen it in Orielly's on occasion, but they will order it. More common is 20W50 and straight weights.
