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.

31 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.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 2Original post

Mobil Purple? Royal 1? You're out of my league!

POST 6Original post

How long for this to start? Do I have time to get popcorn? Could also add...... Which is the best fuel to use?

POST 7Original post

Is it too late to add a tire brand recommendation question too?

POST 9Original post

For street use? It really won't matter, and as far as I'm concerned M1 is fine. For the track, if you have removed your cats, then go for a higher ZDDP content racing oil.

POST 10Original post

I have heard KY can irritate some women... So vasiline? But that is just so hard to wash off....

GG, its like this.. This topic gets way out of hand on this board. Some are very passionate about it to the point of actual arguments. I can tell you I like RP... its just so damn much $$.. I use RP in my gearboxes. In fact its a good fix in a 928 early early year 5 speed box with a grinding 2nd gear. So.. if you ask me.. Yes I like RP.. Is it better? I dunno... I run M1 and change every 3-5K miles. M1, has changed their original formula. Some say.. its like me... As good once, as I ever was, but not as good as I used to be. Or you can say its like the New Coke

POST 18Original post

Unsalted? Really?? I'll have to try it that way. I always used salted on clams, especially on the 1/2 shell.

POST 19Original post

you are ruining your clams (or other shellfish) with putting anything on them other than heat (beit steam, water or fire) El' Natural = the bestest....maybe a splash of saute'd chives/soy sause on my Oysters, thats IT ! butter - EWE!!

IIRC Bruce Anderson covers engine oils and Porsches in his column in the latest issue (May?) of Excellence. And in this month's PCA Panorama Tech Q&A section Slausen also covers oils and Porsches. Read them and then decide. Sincerely, Macster.

POST 23Original post

What a bunch of snobs. You're the reason Porsche owners get a bad rap. if you don't want to help the guy out, why post?

POST 24Original post

Because some people might use the 'search' button to find out what has been discussed so many times before. Snobbery has nothing to do with the above response.

POST 25Original post

Well maybe pointing him in that direction would be the correct reply.

Macster, did you catch Slausen's error? He stated the only two approved viscosities of Mobil 1 are 0W40 and 5W40. Why did he omit the 5W50 approval?
