Yeah, it ran quieter and yeah, dodgy seals wouldn't leak as bad.
Leading evidence: 'Run quieter and yeah, dodgy seals wouldn't leak as bad' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Recommend by the manufacturer' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
I guess I should have used 15W-50 on the popcorn machine instead of the 0W-40, which was recommended by the manufacturer!

Using heavier oil used to be a trick for making a clapped out engine seem healthier when you were trying to sell a car.
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.

Was looking at the newest TSB
http://www.wrightune.co.uk/downloads/approved_oils.pdf
and noticed that Porsche is adding more oils to the list, specifically 5W oils. Do you think this might mean a change in the factory fill to 5W? Certainly would prevent an older engine from leaking as much!

Agreed. Using heavier oil used to be a trick for making a clapped out engine seem healthier when you were trying to sell a car. Yeah, it ran quieter and yeah, dodgy seals wouldn't leak as bad. But you weren't doing it any favours...
Remember the 0 and 5 weights are the viscosity at 0 degrees F. At 60F, 70F, or 80F they would be substantially thicker. In fact if you live in an area that does not get as cold as 0F you will never have your oil get as thin as the W number.
Actually yes it does....
"Multi-weight oils (such as 10W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature. This page from the Sci.Electronics.Repair FAQ offers the following very interesting description of how the polymers work:
At cold temperatures, the polymers are coiled up and allow the oil to flow as their low numbers indicate. As the oil warms up, the polymers begin to unwind into long chains that prevent the oil from thinning as much as it normally would. The result is that at 100 degrees C, the oil has thinned only as much as the higher viscosity number indicates. Another way of looking at multi-vis oils is to think of a 20W-50 as a 20 weight oil that will not thin more than a 50 weight would when hot."
WOW, I was going to pop come corn but my popcorn machine threw a rod and went kaput! Too many oil threads lately. I guess I should have used 15W-50 on the popcorn machine instead of the 0W-40, which was recommended by the manufacturer!
Keine Scheisse!
But doesn't that mean it starts off at one viscosity and doesn't thin as much as a normal single-weight oil? Thus appearing to be a higher viscosity at high temp?
