Here's a post with the email response from Valvoline about the bottles with API SP markings.
I have to double check my new jugs but I think they are all labeled GF-6A and API SP. My new bay box is GF-7A and API SQ. Also has a date on it. June 2006. I forget exact date.
Must mean June 2026. The Valvoline bottles that have pretty new date codes that are labeled GF-6A/SP most likely meet GF-7A/SQ.
I emailed Valvoline about this on the Valvoline Extended Protection I bought back in May and this was their response.
