Yes, I'm sure Porsche is wrong. Thanks Thom, and Happy Easter to you too.

Thom

Yes Porsche is wrong on this matter, whether you like it or not.

Is that bird looking for Easter Eggs?

Luis de Prat

Oh, I'm quite content with Porsche's criteria. You're the one posting sarcastic vignettes instead of contributing to the thread with some facts that I'd gladly entertain.

The only factual contribution you've made here is that we must assume all the OPCs in the world filling cars as per the Porsche list of approved oils are "wrong" because Thom says so.

Wouldn't be the first time race spec is counterproductive in a street application, either.

Thom

I am not going to make any factual contribution on a subject that has been done to death especially when people like you still don't get it and take no acount whatsoever on the significant field experience available.

You keep beating a dead horse based on datas that aren't factual and I'm pretty sure anyway we will always be able to resume this "discussion" in whichever oil topic in any coming year.

Anybody else can ensure me that driving 5w-60 is safe enought?

RAPID944

Yes.

I run 10w60 castrol - 2 bar idle with hot engine in heavy trafic ( 1or 2 hours with first and second) . Otherwise 2.2 - 2.5 at idle in the summer. 195 000km. Oil pump changed wit new one at 150 000km.

Luis de Prat

I've already posted Porsche's list of approved oils. There's nothing to "get" and there's no dead horse here. This is what Porsche says, not me. Look at the list of approved oils. There's not a single 10W-60 viscosity oil on the list, either.

If there's so much field experience available (aside from Charles Navarro telling us to switch back to dino oil when the world is on synthetic) then why don't you post a link to something constructive? Topics get brought back all the time.

I get the same readings with Mobil 1 5W-50. Why was your oil pump replaced?

20w50 VR-1 or Castrol with ZDDP.

At idle:
5 bar when cold.
3.5 when normal warm/hot temp.
3 when it's very hot(100' day, AC on).

I'm switching to ELF 15w-50 this spring so I'll have to see if that changes anything.

eniac

5w-60 may be ok but I would never use that in my car, nor suggest it.

Something just bugs me about that wide of a range....kinda like how all season tires bug me.

Cold start, traffic, and track are the pertaining factors relevant to this discussion. Perhaps some of these aren't relevant to you Luis? When someone (OP) comes on and creates a thread asking about oil pressure at idle, that includes all of us, in all of those circumstances. Therefore we give our views. For me and several others all 3 of those factors are relevant. Just because you have found a list of approved oils that is supposedly generated by Porsche worldwide (?) doesn't mean it's right. Same as when they were running around the track with their racecars emblazoned with a certain brand when they were known to have been using another. Which one should I use in that case? I would doubt that any list that Porsche currently quote would be taking our cars into consideration anyway.
So you keep using the oil you're happy with and we will do the same. No problem.

Luis de Prat

If you read it, it clearly states that it applies to Porsche cars built from 1984 onwards. If you have a 951, then it applies to your car.

No problem here, just reiterating readily available information which again, if you read it, was published by Porsche AG. Just like several other tech bulletins, recalls, etc. that are definitely worth taking note of (cracking single piece 951 manifolds, 968 M030 caster blocks on 17" wheels, etc.).

These docs are published by the manufacturer which in and of itself has more credibility than a thread on an internet forum.

After about an hour of city driving I get down to 3 bar at hot idle running Penrite HPR 15 with is a 15w-60, http://www.penrite.com.au/products.p...&id_products=3.
Had previously been running Mobil 1 and didn't like the look of the low oil pressure seen on track days, so am giving Penrite a go. Valve train seems a lot quiter also. Says in the specs that it meets Porsche GM 6094M whatever that means.

Heres a FAQ entry on ZDDP I found on the Penrite website-
"Zinc Dialkyl, Dithio Phosphate or just plain zinc ? whatever you call it, this is the anti-wear additive of choice used by lubricant manufacturers around the world. It?s used for its ability to protect your engine when actual metal to metal contact occurs. With a good quality oil, this will rarely occur, but if it does, the zinc compound reacts with the metal to prevent wear. There have recently been concerns about lubricant blenders reducing the level of zinc in their oils."
