Gasoline Octane

[Belledan]

Can anyone confirm if the 986 ( mine is a 1998) can be safely run on 87 or 89 octane? The manual suggests that lower ocatne can result in engine "damage". They put quotes around this which makes me wonder why they are qualifying the word damage, A recent find on the internet discoverd the follwing from Porsche's own engineers...

All Porsche engines are designed for premium, too, but it's not available everywhere. "Our cars must be able to drive all over the world, and so we are able to run on regular," says Jakob Neusser, director of powertrain development at Porsche's research and development center in Weissach, Germany. "You don't have to feel that a mechanical problem or anything else will happen" using regular gas, even in the highest-performance, regular-production Porsches.
