Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.
0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

I'm about a quart low and not ready to do a full oil change. My local Walmart only has Mobil 1 0-30. Is there a problem mixing in a quart of 0-30 with the 0-40 that's in the engine? The temp in LA (where I live) is in the 70's these days.
I was told that 40 weight is the lowest to go. I almost did the same thing but then referenced the post Loren did about the oils, and 0-30 was not an approved Porsche weight. I got a couple of boxes from Kragan they had it in stock auto zone also did, but pep boys did not.
Purist would say NO Pragmatist would say Yes How can it hurt?
