Definition of Base Stock and Slate by API 1509 Appendix E
E.1.2.1 A base stock is a lubricant component that is produced by a
single manufacturer to the same specifications (independent of feed
source or manufacturer’s location); that meets the same
manufacturer’s specification; and that is identified by a unique
formula, product identification number or both. ……..
E.1.2.2 A base stock slate is a product line of base stocks that have
different viscosities but are in the same base stock grouping and
from the same manufacturer
E.1.2.3 A base oil is the base stock or blend of base stocks used
in an API-licensed oil
21
Is YUBASE plus the same slate ?

Definition of Base Stock Slate by ATIEL CoP
A base stock slate is a product line of base stocks that:
(i) are produced by the same manufacturer
(ii) meet the ATIEL definition of base stock
(iii) are in the same ATIEL Base Stock Group
(iv) may have different specified viscosities and other properties
(v) have been demonstrated, in lubricants for which compliance with
ACEA Oil Sequence is claimed, to be technically substitutable by
other appropriate base stocks on the same slate
A manufacturer may have more than one base stock slate

Summary
Higher VI Group III Basestock, now available
Base oil manufacturers continue to search for innovative ways to
maximize iso-paraffins and small-ring naphthenes in base oils
YUBASE plus is the first higher VI Group III base stock in the
merchant market
There are no advisable effects in low temperature low shear
property, seal compatibility and fuel economy
YUBASE plus is the same slate as SK’s Group III base stock,
but different base stock
In several API engine tests, YUBASE plus based oils showed better
results, and ACEA engine tests are conducting to demonstrate
Base Oil Read Across between existing YUBASE and YUBASE plus
