Suggestion

Swepco and a couple other smaller oil companies, who have always made a decent profit from their superior (but more expensive) oils, don't seem to be short-changing their customers in this way.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Since I switched to Swepco 201 tranny fluid the car seems hesitant to leave first for the first couple of hundred feet it's driven. Anyone else experience this? 01' 6-spd

POST 2Original post

Swepco 201 is the wrong lubricant for your transmission. The factory fill is a Mobil product that is not generally available in the U.S. except from the dealer, but my dealer always seems to have it on back-order. Lufteknic sells a product that seems to work pretty well.

POST 3 / ORIGINAL POSTEROriginal post

I was aware of this when I put it in but the local Porsche racing shop said it was fine as well did Suncoast Motorsports...... If it continues to bother me I will change it the recommended Mobil product. Thanks

POST 4Original post

Swepco is great in my old 911's 915 tranny but I was told by my indy and the dealer not the right lubricant for the 996

POST 5Original post

Swepco 201, as with any dino oil, requires a warm-up period of a few minutes before it will allow smooth shifts. Mobil 1 or other synthetics will likely provide better shifting in the 996, but probably not better protection for internal components (than 201).

POST 6Original post

I replaced my tranny oil with Royal Purple and its fine. Its not as smooth as the Mobil1 though. Just make sure the spec grade is the same as Mobile 1. I believe its 90 NS GL5 with a friction modifier.

POST 7Original post

The 901 Shop quit using Royal Purple after seeing a new OEM 8:32 disintegrate after 4 hours race time. It's suspected that the Royal Purple gear lube has been reformulated to be "more economical to produce" (as we've seen over the past couple years with numerous engine oil producers). Swepco and a couple other smaller oil companies, who have always made a decent profit from their superior (but more expensive) oils, don't seem to be short-changing their customers in this way.
