Why Motul? Well, in my experience cars runs cooler, oil PSI a little higher, no oil consumption and finally great reports back from Blackstone labs!!!

NAM VET

my GT3 ran at hot idle 1.5 bar with 0-40 Mobil 1 and 2 bar with 5-40 Redline. But then I don't think it takes much oil pressure to protect an idleing/no load motor. Both pegged the oil pressure with any rpm at all. I use the appropriate Mobil 1 oils (the ones with the higher levels of anti-wear additives) in our other cars, but my GT3 gets Redline.

All modern engine oils are superb lubricants, some are even bette.

All the best....

This was my first thought but now I am not so sure. I believe Motul is superior to Mobil1 but this is (was) a problem for me.

Yes. meant sensor. Tx

My concern w spin on stuff is that there are times when you want the filter to be bypassed, ie in extremely cold weather or in the case of a clogged filter. Sometimes the alternative to bypassing filter is no oil ie dry running engine. I have yet to see a long term test of engine wear between these systems and in different climes or conditions.

I'm going to have to follow up on this. Just cost me 1200$ for coils, plugs, service so I'm laying low for a while. I'll post what if nething I find. Thanks

UPDATE: testing sensor using test suggested by fellow 6 Spdrs

(IE: with motor off, turn switch to acc. position. Gauge should show no deflection)

it appears the fault lies with the gauge readout. The coincidence needed for this to happen is huge and hard for me to believe
but I will have sensor replaced and go back to Motul in the future. We will see what happens.

Thanks to all for the input.

Yeah, mine read with the engine off too. You'll be good to go with a new sensor.

The part is pretty cheap and it's not a bad DIY.

You can also try cleaning the contacts but I had no luck with that.

Ok thanks

I occasionally get about 1 bar of oil pressure wit my engine switched off (like cold, prior to starting it). Ask me if I worry about it? The stoooopid thing lives its own life. And clearly enjoys it too. Talk to Ferrari owners who swear their cars are possessed. Just enjoy gremlins in your OP gauge.
My baseline is 200*F = 2 bars of oil pressure at idle speed with 5W-40. IF the stoooopid gauge behaves well. Big, fat IF that is.

I wish it was that simple my friend:



Just listen carefully what actually Porsche people have to say. And keep in mind that the 996's have already been inducted to the 'Classisc'.

No one I know or have read advocates for the use of modern synthetics in vintage water cooled motors. Water cooling allowed for tighter running tolerances thus meeting stricter pollution standards. I'd argue that 996 falls into later category and is best served by synthetics. Among the current synthetics I'd say Mobil 1 is a Red Label Dewars compared to the Johnny Walker Black top shelf Motul and Redline offerings. Mobil does pay a lot for advertising. It will do the job. Motul has the advantage of being plant based and renewable for us tree lovers. Cheers and thanks for the clip.

Every single specification has a range: from - to.
I prefer Macallan.
996 is classic:

What I'm trying to say is that it will take Porsche another 20 years to admit that the A40 isn't quite applicable to 996 and 997 as both platforms age.

Happy to help.
