    Mike......IIRC the original Cayennes had an oil change interval of 20k kms. Our '09 has the revised interval of 15k kms in the owners manual with recommendation to use Mobil oil.

    I chose to ignore both recommendations using full synthetic Shell Rotella at 10k kms interval with a new oil filter and have being doing so since we owned the SUV. At +250k kms and counting with no engine issues and no oil consumption at all between changes Id say its working fine
    '93 928 GTS 5 speed
    Polar Silver/Linen, 192k kms

    '88 928 S4 A/T
    Black/Ivory, 190k kms

    '09 Cayenne GTS Tiptronic
    Nordic Gold/Black, +290k kms

    '88 928 S4 A/T
    Red/Champagne, 110k miles (US car)

    Neighbour had an Ď08 Turbo, started to make a funny ticking sound so he sold it immediately. Sounds like the same issue.

    Definitely. You cannot change your oil too often. I think Range Rover was peddling the same nonsense but happily the one I bought had documented oil changes every 10,000 km. I'm sticking to an 8,000 km interval in that car from now on.

    Jake Raby has done videos on bore scoring that are interesting. He doesnít have a definitive conclusion as to the cause, and occurs in other makes as well. Best answer is Nicasil cylinder liners.

    I'm sticking to that with my Cayenne TT as well - I figure a couple of jugs of oil and a filter are cheap insurance.

    Hello Gents,
    My 2cents...... Was bore scoring ever an issue with older cars? One theory (Jake Raby) out there is that it is due to fuel dilution, especially with direct fuel injection engines. Leaky or poor performing fuel injectors, combined with long engine oil drain intervals can lead to problems? He suggests adding an injector cleaner to the gas occasionally.
