Yes, great price but please be aware that very well qualified M96 experts(not me!) do not recommend Mobil 1 for the M96. Search threads for "JGDT40" for more.

Plenty of threads for oil debate! And plenty of Mobil 1 users as well; enjoy the cheap oil if you're one of them!

Been running Mobil 1 for over ten years and 100,000 miles. Think I'll stick with what the Doktor recommends.

Walmart?


Wal MART?


WALMART in a 986 post on Porsche?


You actually drive your Porsche into a Walmart parking lot?


Someone take that man's man Porsche keys!







Just kidding :D

I drive it to Wally World every once in a while, but I always feel dirty afterword. :p

My car has 90k + and has always had Mobil 1 (full service records). I think I'll stick with it. ;)

Have you changed out your IMS bearing? ;)

My wife and I just got back from Walmart in our 01S....sometimes we like to feel a little dirty :rolleyes:

Saw a Tesla in the Walmart parking lot this evening.

No problem with IMS and Mobil 1.

The best time to do the IMS is before you have any problems.

Mobile 1 checking in. 0-40W.

The oil debate is one of the things that makes me hate the Internet. You have relatively normal people who will yell and scream at other relatively normal people, neither willing to budge from their positions, neither with any actual evidence of superiority of their position and both with the riteous indignation that their position is the correct one. The result is entrenchment, name calling and butt soreness with nothing gained for the trouble.

That being said Mobil 1 is what is written on my car and that is what I use.

Mobile 1 here, but after reading Bob is the oil guy and other posts here it appears there may be better options than the Porsche recommendation. I'm at "good enough" with Mobil 1 for my backyard shade tree mechanic rebuild.

are you sure it's 5qts? Our walmart is 4qts at that price

I was referring to your belief in the "Doktor", who also gave you your infamous IMS... :cheers:

Which, by the way, has not failed me in over 100,000 miles. I'm pretty satisfied.

The formulation of Mobil 1 has changed significantly since it was originally recommended by Porsche for the M96.
Check the JGDT40 threads and Bitog site for specifics.
Tribology has advanced a lot since the 1990's ,so it is possible to spec an oil more closely to the M96's peculiar needs now than it was 20+ years ago. These criteria become more important as the miles accumulate on an M96 ?
Just compare the specs of the Old vs.New Mobil 1 and JGDT40. Significant differences .

Need more than that
 

How about some hard facts, I use Mobil 1 in my 01S and my E36, Nissan SR and Honda CRV and have had nothing but good luck. Im not being a Mobil 1 fanatic, I believe actually any top leading oil should be fine as long as the engine is in good condition and has been kept serviced....but show some serious facts please.

Everyone's a fargin expert
And opinions are like iceholes, everyone's got one and some are smelly and stinky

In any case, $24 for 5 quarts is a bargin

Its for real
 

Mine has wobble and no grease at 130k miles. I'd consider it. Glad I didn't skip it.

My 04 has the Mobile 1 sticker.

Hold on. I'll do that math. Seems 20+ year claim is too much.

Hey. 11 years. :confused:

^ Bingo.

We have heard from people who take these engines apart AFTER 100K miles, and they all seem to be on the same page. If you can budget for a better quality oil, you definitely want to do so. This isn't a Jetta.
And none of these engine experts are wild about Mobil 1 on these older cars. The Tony Callas piece in Excellence Magazine some time back was interesting to me. Here is a magazine that is heavily "influenced" by having a good
relationship with Porsche (and their official oil) and they still printed his opinion that "mass market" oil are not such a great idea anymore as they see fewer and fewer protective additives going in. And not surprisingly.... the prices have been coming down, even before this (temporary) crude oil collapse. Meanwhile those protective additives.... yep still expensive.

Like anything else in life, as the engine gets older, it needs more looking after. When you've got a brand new engine and you're getting every one of the ponies you paid for, the old Mobil 1 was probably okay (so as long as you drove the car frequently and didn't let it sit). As it gets older it needs some extra protection. Buying oil you'll change once a year, in most cases, on the basis of which is the cheapest acceptable option is nuts.
What's worse is if you register low mileage and the car sits for long stints, then the cheapest acceptable option isn't really worth the $50 you saved and spent on dinner that night.

Where are the specs for JGDT40? I can't find the ZDDP numbers for example.

This is a good article. Really long but informative.

I am not all that convinced the above link is something I would trust,

If he is that good of a of an engineer I would of expected a write in a professional organization magazine.

Think I will stick with what is working for me.

Mobil 1 0W-40 has been fine for me. It also makes recycling the used oil easier pouring it back into the 5 qt jugs, instead of messing with trying to pour the used oil into all those 1 qt bottles.

You listen Jake Raby? We need the the DT40 in 5 qt jugs!

If we had ZDDP numbers for JGDT40,would we know if it is good/bad ? Tribology is a tough enough subject to master but when you overlay the M96 quirks on the subject it becomes fiendishly complicated to figure out which is best oil based on any data.
It comes down to faith in whoever makes a recommendation. So it is a 1990's Mobil spec that is no longer available vs.JGDT40 Lake Speed/Raby.
This link gives some comparative data for Mobil 1 vs. JGDT40.Just scroll down to the piece on oil.

No...but it's a start. And they specifically advertise the product as "high zinc". "High" is relative. I'm a science person - I want to see numbers back up a claim.

No offense since you seem like a good guy with good intentions, but these statements made my jaw drop! :eek:

I never take a manufacturers word for their product as they are obviously trying to turn a profit. It's not difficult to make the choice to educate yourself on a subject. ;)

Yes, I want the ZDDP numbers for JGDT40 and yes, anyone can choose to understand them.
Personally, I never make an uneducated choice based on "faith".

...and the next step is entrenchment and then name calling.

And then
 

The pie throwing :rolleyes:

And then...
 

...Cats. :D

I'm totally in for cat throwing.

Been using Royal Purple for 5 years now. I like it because it looks the same going in the filler tube as it does coming out the drain pan, keeping the mystery alive. Is it cleaning or not? Who knows!

It never goes on sale at Wally world :(

have you had an oil analysis? I don't think we've had a member using RP post one in the GD section.
