Yep, all three stated above. And I think they all charge just under $4. Compare the inferior (IMHO) Maxlife Engine Protector, which often sells for nearly $6 and from VOA data has nowhere near the goodies the Synpower stuff has. I have three bottles of the Synpower stashed and may buy more. My main use is to thicken 10w30. The additives are a bonus.
Hmmm, I don't recall ever seeing it at Meijer and they recently sold off their Maxlife Engine Protector at $3 a bottle.
