This was reformulated years ago and reduced the zinc levels.

Valvoline VR Race 20/50 is my preference and is available both on the shelf at S-K (local speed shop) or mail order for a fair price and free shipping with Prime.

Not according to recent request to shell's tech department that I have seen.

If you want less viscosity than 20w50, the VR-1 also comes in 10w30. Most parts stores seem to keep 20w50 only on the shelf, but my local NAPA also keeps some 10w30 in stock, but I have to ask for it.

I have heard this as well, and only really had 1 or 2 guys using it back then. I didn't care for it too much to be honest so I haven't really looked into whether or not they changed it.

Unfortunately the VR1 isn't offered in 10/40 that I know of, but our builds predominantly use the 20/50 stuff anyway and like Adam mentioned, it's real reasonable price wise.

I have been using this 20/50 for a couple years now no issues what so ever and the local parts store had it on sale last month for cheap money, I cleaned them out
