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.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

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

The Mobil 1 you buy in the gallon container (which is a completely different product than the stuff you buy in a quart) is excellent, and is supposedly used by Farnbacher Loles.

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.

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

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

POST 1 / ORIGINAL POSTEROriginal post

what is the current favourite manual trans. oil to use?

POST 2Original post

I've tried Royal Purple in my Mazda and it did improve the smoothness and action especially when cold even though it was pretty good to begin with. The shift action is light years better than the Boxsters. I'll probably try it in the Boxster next and hope it smooths out the trans since it doesn't feel so smooth right now.

POST 3Original post

Redline is the best stuff, not sure if they have the correct ones for our cars tho.

POST 4Original post

I've tried Castrol full synthetic and was not too happy with it. I switched to Mobil 1 and it's fine. The car is still difficult to shift when cold, but once warmed up it's fine. Still I'd try something different the next time I change the trans oil. I'd still prefer something a little slicker than the Mobil 1. Kirk

POST 5Original post

I have the Redline 75W90 in my box right now, and it's fine. The Mobil 1 you buy in the gallon container (which is a completely different product than the stuff you buy in a quart) is excellent, and is supposedly used by Farnbacher Loles. While I have not tried it, according to Paul Guard (of Guard Transmission fame), the best stuff available is from Lubrication Engineers.

POST 6Original post

I've used Royal Purple in my 5 speed boxster and I liked it.
