Personally, my cars all genuinely seem to run better after they have been thoroughly cleaned, though I don't expect that is actually the case!

If you had a "classic" 996 it would likely simply recommend 5W-50 Porsche Classic Motor Oil for Group 1 countries of which Australia belongs.

Porsche frequently issue updates to their oil recommendations for their cars to make the most of continuing improving oil technology (or to correct previously poor oil recommendations!)  If you Google "Porsche Recommended Engine Oil For Model Year 1984 and Newer Porsche Vehicles" you should be able to locate the most current issue.

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

Hi everyone I'm planning my move back from the UK along with my 997. Currently I'm using Millers oil here and find it works really well. I was wondering what the general consensus is on choices of available oils people are using. Thanks in advance everyone.

POST 2Original post

Quotes source post: 358984

Kul, my mechanic has changed my 996.1 GT3 to Penrite 10Tenths Racing 15W 50.  Penrite is quite well regarded in Oz, and my car seems to like the new drop 🙂 Maybe different grade would be appropriate for your car given different requirements. And when you get here, make sure you only use BP or Caltex / Ampol fuel.  Best quality of the options available here..

POST 3Original post

In my 997.1 C2S I’m also using Penrite but it’s 10 tenths 5w50.

POST 4 / ORIGINAL POSTEROriginal post

Thanks for the updates. I appreciate it. Also, just wondering what sort of oil temps your cars run as its a bit warmer over there than it is here.

POST 5 / ORIGINAL POSTEROriginal post

Just been looking on the inter web - is this oil any good: ULX110 Motor Oil?

POST 6Original post

Liqui Moly Molygen 5W-50. Changed it this weekend after running 5W-40 and it seems a little better on a long run.

Can't say I've ever heard of that one I  must admit........

POST 8Original post

I have found that my Turbo likes the LiquiMoly synthetic.

POST 9Original post

Quotes source post: 359100

Agree, I reallly like the Liqui Moly products and so do the cars (996.2, Amarok and RR Velar)

POST 10Original post

Not meaning to be provocative, I do wonder about how much placebo effect there is in some "my car runs better on X" opinions. Any of you guys have any data / test results which support otherwise subjective views? Personally, my cars all genuinely seem to run better after they have been thoroughly cleaned, though I don't expect that is actually the case!

POST 11Original post

Validating fuel usage, engine temps etc. via ECU logs (aftermarket and stock ECU's), vbox readings, oil analysis and of course the highly calibrated seated pants potentiometer give you a good idea of whether oil or oil additives make a difference. We have on some of the race cars noticed substantial differences in wear rates, engine performance at temp (temp stability etc) on dyno and track as well better results in the oil analysis. IMHO, oil performance isn't always about more power.

POST 12Original post

IMHO oil performance is never about power - it is about thermal, mechanical and chemical stability and the impact that has on component protection given the intended use case. The biggest objectively measured variation in power/ wear / response I have seen across race and road cars is significantly more a derivative of oil viscosity range when using quality engine lubricants.

Kul, You will quickly learn that there is no value is asking oil questions on a forum. The best way is to work it out yourself through 3 easy steps: 1) Check the Driver's Manual For your car it will recommend a number of viscosities depending if you commonly drive the car above or below -25 degrees C.  For Australia's ambient temperatures it is likely SAE 0W-40, 5W-40 and 5W-50 viscosities will be recommended. It will also likely recommend suitable ACEA or API oil classifications.  However it is most likely for your car it will just say to use "Porsche Approved" oil. 2) Check the Latest Porsche Technical Bulletin Porsche frequently issue updates to their oil recommendations for their cars to make the most of continuing improving oil technology (or to correct previously poor oil recommendations!)  If you Google "Porsche Recommended Engine Oil For Model Year 1984 and Newer Porsche Vehicles" you should be able to locate the most current issue. It will likely simply recommend their "A40" Porsche approved oil.  If you had a "classic" 996 it would likely simply recommend 5W-50 Porsche Classic Motor Oil for Group 1 countries of which Australia belongs. 3) Visit Your Favourite Local Car Parts Provider Identify the oils on the shelves that have the required approvals/viscosities specified above and select the one that appeals the most. For your car this is likely to be Shell Ultra 5w-40, Mobil 5W-50 and Mobil 0W-40 (which was actually the factory fill oil) as these are the most commonly available oils here with "A40" approval.
