Looks like ZDDP Maxx and the Eastwood packaging are all going defunct now. The little bottles have been redone before, and the old stock sold out for cheap. Beware, old stock will settle out part of the ZDDP solids in the bottles over time .... cut your bottles open to check on this after you empty them or refill them with clean oil and reheat and agitate strongly to get the goodie out of the bottle.
We had a theory that it was all really the same company at one point in time, with different brands being sold at different price points, with Eastwood being the cheaper brand and ZDDP Plus being the primo brand. And now we have the ZDDP MAXX brand as well.
Who knows ?? -- assume you can use whichever small bottle ZDDP concentrate you buy at the list mix ratios as found in the tech section.
