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.

POST 1 / ORIGINAL POSTEROriginal post

Did my first oil change yesterday on the C4S yesterday. Ramps and jack stands for space and a lot of oil. I ordered PU 5w-40(is a Porsche A40 approved oil). Decided to stick with the cartridge filter. Cut the old one open and all looked well. The PU I ordered on line as "24 quarts" it arrived last month but I didn't do more than a cursory check to see if the oil was the right stuff. Well yesterday found no quart bottles. Only a 24 quart BAG of oil. It's like having the box-wine of oil only not so cheap. Sent from my iPhone using Rennlist

POST 2Original post

That's actually kinda cool. I'm a Rotella user myself and I've considered just buying the 5-gallon buckets since almost all of my vehicles use the same oil.

POST 3Original post

what was the damage for that box o oil ? never seen it sold like that

POST 4 / ORIGINAL POSTEROriginal post

The oil was $190 delivered. That is $7.91/quart. When I ordered it it was the cheapest but right now there are cheaper available as 6 quart packs on Amazon Sent from my iPhone using Rennlist

Smoking deal on the Ferrari limited edition oil

POST 6Original post

I've been using Mobil 1 0W-40 on my BMW's and my Porsche for a while now. I noticed the guy with the 400k mile 911 Turbo uses that weight exclusively and that's good enough for me.

POST 7Original post

That's cool, but how will you access your tools now?
