I use different oils in different cars depending on much I care about them.

I use the first one, which is what my porsche expert recommended.

I haven't done my own oil change on my 911 yet but I will either use that or use what the previous owner gave me, I forget off hand what it is but I know it's been recommended here before.

Thats one reason why some workshops specialized in Porsche recommend Liqui Moly over Mobil, because you are always sure that you are getting the European version (Liqui Moly doesnt manufacture for US like specific market)
Recommend product itself since porsche a40 oils have limitations

From the many threads I've read here in the 996 forum, it appears many people are looking for a "better" alternative from a Porsche A40 product or the factory recommended product itself since Porsche A40 oils have limitations.

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.

Go with Motul X-cess 8100

I use the first one, which is what my porsche expert recommended. Actually although both fulfill the Porsche 04 standard, if you see, one is BMW LL 01 (Longlife spec for fully synthetic) and other is BMW LL 98 (an older spec for LL semi and full)
I ended up with the second one (Synthoil Premium). Haven't dumped it in yet. Still have the Mobil 1 0W40 (as far as I know) in the engine from the previous owner. This actually gets a high rating for wear protection on the
super
motor oil blog.
Has anyone used this?:
Amazon
Amazon
It's the highest rated 5W40 at the super blog (for wear protection).
I am kind of "brand" guy when it comes to aftermarket parts (maybe because I work for an OEM and aftermarket parts brand). I would never buy an oil from a brand that I dont know. Castrol, Mobil1, Liqui, Total, Motul, etc... your choice. I trust on that brands and their top products. I could say the same about, filters, sparkplugs, bearings, tires, etc.
My recommendation is to put your confidence on those companies with higher resources for R&D more than in the internet tests or forums. For instance, it can happen that you have a good rate in wear protection... but that is achieved with a trade off on detergent or any other oil aspect.
Do you consider
Joe Gibbs
one of those "brands"?
There are a lot of crappy oils out there from brands like Mobil 1 and Castrol. My confidence does not extend to companies that use marketing hype and process/ material thrifting. It was a simple question. Don't want to start the typical - not to be discussed topic: a) politics, b) religion, c) type of oil to use.
No I don't. Actually I had never heard about that brand and probably I would never use their products if I can choose.
Of course there are also good and bad products from well know brands, but I know how the big players trusted by OEMs work, and yes, there is a lot of money in marketing... but there is much more in R&D and Quality processes.
But as I said, is not for starting a debate. Is only about personal preferences. Sorry if I border you with my answer
No worries. I understand your perspective and can't argue against it. You probably wanted a different word, I certainly wasn't bordered with your answer.
Is all Mobil 1 0W40 the same? The 0w40 on the blog that is high on the list is the Mobil 1 FS "European Car" blend. Note the local Napa carries two types:
https://www.napacanada.com/en/p/ESS110538
- Regular Mobil 1?
https://www.napacanada.com/en/p/ESS124034
- FS Mobil 1?
If that isn't bad enough, there is a Mobil 1 0w40 "ESP" version, which maybe can see into the future.
With Mobil1, you have to be sure to go for the: "
Mobil 1 FS 0W-40 European Car Formula (North America) or Protection Formula (rest of the World) Advanced Full Synthetic Motor Oil
"
UK Page

I dont know which are the differences with other Mobil1 0-40W, but that one is the one Mobil1 recommends for a 2002 911.
Here you can see the difference in certifications between two options

Thats one reason why some workshops specialized in Porsche recommend Liqui Moly over Mobil, because you are always sure that you are getting the European version (Liqui Moly doesnt manufacture for US like specific market)
I use the first one in my Audis and have never had a problem. I also add in one of their mos2 anti-friction additive every oil change. I haven't done my own oil change on my 911 yet but I will either use that or use what the previous owner gave me, I forget off hand what it is but I know it's been recommended here before.
I am going to get flamed.
5w40 Castrol Edge. What is wrong with it? It has the vw, Porsche, API, bmw etc. Certifications.
I hear criticisms of Castrol that it is from oil stock, not truly synthetic etc. The main reason to be quite blunt is that it is reasonable price, easy to get.
Can it predict when my engine will fail, if I use it?
That is one of the
wonderful
things. Just about every maker has two or three "varieties" of the same grade. Mobil 1 is one of the worst offenders. And yes - what's left of my 5-qt jug is the "FS" formula. If the blog is to be trusted, the Liqui Moly is significantly lower rated in wear protection. But then again - he's only tested one of the two formulas listed in the OP. Maybe I got lucky and order the
right stuff.
...
lol. It could be argued that your list should have: d) what's the best tire?
I'm not fanatical about any particular brand. I look at specs and if a quality oil comes up on sale, I'll pick up a case or two. I use different oils in different cars depending on much I care about them.

That is one of two I bought off of Craigslist to make a trophy for an annual vintage BMW event that I co-host. It is the
Captain Hazelwood Perpetual Trophy
. Each year it is awarded to the attendee whose car leaks the most oil on the ground.
For what it is worth, the Synthoil is not Porsche A40 approved. If that matters to you 996 guys that is, I suspect it may not. Take note that it will not hold 22.5 from Mercedes so it will have too high of a NOACK # to claim that spec (usually north of 9%) so oil consumption, oil thickening and poor additive retention can be key factors here. Our X-cess 5W40 will be Porsche approved, higher in ZDDP vs the M1 0W40 and better additive retention too so you'll have a nice step up in oil performance vs that product.
Molygen is also not a Porsche approved product with a surprisingly high NOACK of 11%- this is also the same reason the Castrol Edge 5W40 product is only 229.3 approved and not 229.5. The LQM 2332 is the Porsche approved product and is at the max limit for NOACK at 10%. I think you could do better here...
First and foremost, LQM makes a great product BUT there are clear differences in the formulation. I mention the NOACK as our Porsche approved 8100 X-cess 5W40 will have a NOACK in the 8's. So in theory, you'll have a 20-30% less volatile product as it relates to oil evaporation and oil thickening which then leads to higher engine wear, poor oil circulation and higher oil temps. All big concerns with an engine in the rear of the car.
Hope this helps anyone with their oil choices on this thread. -Nick
I recently switched for good to Motul 8100 X-cess from Lubro Moly.
Ln engineering recommends it and Dt40 for the 996. It works in my jetta Tdi also. It is only 37 bucks for a 5 quart jug on Amazon prime. Can't beat that.....
Hi Scott,
What I implied was in fact the opposite- sorry about that. That 996 owners appear to take their oil choices may be even more seriously than other sub forums here. Meaning, 996 guys may not care about the Porsche approval considering the infamous dialog in regards to ZDDP and the speculation (or fact) that it is related to IMS bearing failures. From the many threads I've read here in the 996 forum, it appears many people are looking for a "better" alternative from a Porsche A40 product or the factory recommended product itself since Porsche A40 oils have limitations. Sorry again if that was unclear. -Nick
Where are you reading that it is not Porsche approved? It's even got Porsche A40 on the bottle...
https://pim.liqui-moly.de/pidoc/P001758/8576-MolygenNewGeneration5W-40-32.0-us.pdf
Specification/recommendation does not equal approved. Please see below for the differences of their approved product (Leichlauf)- where the approvals are listed separately from the "recommendations." Where Molygen only lists the recommendations since it carries no approvals actually. This is not unique to LQM, we as many others have a product line that lists specs too but are not approved.
Lesson being, looks for "approved, approvals" when buying your oil. It is easy to assume "performance, specifications, recommendations" mean the same thing. They do not. -Nick
Molygen technical data info:
Leictlauf technical data info:
For the same reasons sighted above- 20%-30% less oil consumption, improved flow rate and better additive and viscosity retention over your respective drain interval.
See ya next week lol. -Nick
PS: We do not stock any oil in Cypress.
That's some amazing information! I bet you hang out over at Bob is the oil guy.
