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.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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

I've always had the suspicion that I got slightly better mileage with Chevron. Just due to the routes I drive, I either fill with Chevron or Shell high test. Opinions/suspicions are ok, but I prefer data. I was working on some tax numbers today and happened to review the numbers for the Porsche. As I use it in business, I keep a log. During 2007, I put 7057 miles on my '03 996. About half the time I filled with Chevron; about half the time I filled with Shell. By the end of the year, I had 24 visits to Chevron & 20 to Shell. Mileage, gallons & type of fuel were logged. Taking into account what was actually in the tank when the mileage numbers were created, overall, I got 22.76mpg for the year. Chevron = 22.4; Shell = 22.8. The difference isn't significant. So, what this tells me is that it really doesn't matter & just shop for price or convenience. Worth knowing. Discarding a misconception can be more powerful than learning something new.

POST 2Original post

Good post. Assuming same refinery area, pump gas has very little variance from name-brand to name-brand in the actual fuel, it's really just the additives that differentiate them.

This is a source reference. Confirm exact model applicability in the original material.
