Agree, had quite a stash myself but culled it down to only the 0w20 based on these UOA reports. I did have a sundry of single quarts, and made a custom jug which is probably an additive clash of 0w20, 5w30 and 5w40 Total, but its being used in OPE so probably wont explode but Lake Speed Jr might be frowning a big frown.
Still have 4 quarts of 10w60, will probably use it to help along burning brush this fall/spring.
