Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion · Original poster
If you’re tracking the car heavily, the ESP X3 0W-40 is still robust enough, though some enthusiasts opt for alternatives like Motul 8100 X-Clean GEN2 5W-40 (also C40-approved) for slightly better high-temperature stability—perfectly legal under warranty as long as it meets C40.

Coverage and how to read this overview

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.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Guys - I’m getting a little confused over which oil I can use in my 718 GT4. Owners handbook says Mobil1 C40 (0W-40) which Google suggests is the “ESP X4” which was previously X3. But there’s also a GT specific oil which I think is only for the RS. Can anyone help, with a link if possible? UK based. Grok says: For your UK 718 GT4, stick with Mobil 1 ESP X3 0W-40 (or X4 if available), as it meets the C40 spec required for your GPF-equipped engine and is Porsche-approved for your model. The Mobil 1 C40 GT 0W-40 is meant for the GT4 RS and similar 9K RPM engines, not the standard GT4. If you’re tracking the car heavily, the ESP X3 0W-40 is still robust enough, though some enthusiasts opt for alternatives like Motul 8100 X-Clean GEN2 5W-40 (also C40-approved) for slightly better high-temperature stability—perfectly legal under warranty as long as it meets C40.

Grok pretty much correct. I would run Mobil 1 ESP X4 0W-40 (C40) C40 GT only for the engines specified below : https://www.mobil.co.uk/en-gb/engine-oil/mobil-1/c...
