Rotella T6 for my 986

[Fuzzuki]

Never heard of anyone using Rotella T6 in their Boxster.

I love using it in my wife's Suzuki Sv650.
Price is right. Works really nice.

Is it OK for the Boxster?


How much old does it take?

[Fintro11]

Not sure about T6 but had nothing but problems with rotella in our work vehicle ended up switching to chevron and have never looked back.

I use motul in the boxster

[BoxsterSteve]

I've read of its use in M96's, only consideration being extended high RPM usage which can cause excess foaming.
Oil capacity is 8.5L, give or take.

Motul 8100 X-Cess 5W-40 is a good choice
20 liters delivered on amazon is ~$125

If you really want a validated recommendation ,just "Search" JGDT40.
There are lots of Ford turbo diesel approved oils(like some grades of Rotella ) and their attraction is lack of foaming.But this is only significant if you operate at very high revs with the M96. They usually have good shear and thermal stability but JGDT40 outperforms them in most relevant specs. Given the vulnerabilities of the M96, why take a risk ? The slight premium for the best suited oil may be valuable piece of mind ?
Another consideration is that if you buy the JGDT40 from RND you can get a free UOA from an M96 expert. Now that IS significant imho.

t6 diesel 5w40?yep i change it every 3-4k though

Ok if "Porsche A40" is printed on the bottle.

If not, no.

Just think ... Porsche oil at a Walmart ...

Here is a link to what A40 means:

updated here, doc is garbled but the Posts cover the gist of it:
http://rennlist.com/forums/996-forum/923972-new-2015-list-of-porsche-approved-a40-oils-and-a-strange-change.html
The list does not include some oils that exceed the A40 spec for the M96 specifically.
The benchmark for comparison of M96 oil is JGDT40 according to the M96 experts.
Obviously the engine will not explode as soon as you fill it with something else but unless someone is both a tribologist and an M96 expert,how can they credibly contradict the experts and mislead(perhaps) other Forum members ?
I am neither a tribologist nor an M96 expert,I just pass on a digest of many prior discussions of this subject.

I read years back Rotella was good for break in of engines due to it's higher Zinc content....but not sure now.

For that specific role there is JGDT Break In oil.
I mention this because if you just spent the $$$$$ to rebuild an M96 ,why would anyone worry about a few extra $ for what the experts say is the most suitable oil ?
I am all in favor of using Walmart oil - if it is just as good as JGDT -but how can you be certain?
Just imagine the Thread title: " My newly rebuilt M96 exploded - do you think it was the cheap oil I used ?"

Actually IIRC, you are referring to one M96 expert who was involved in the development of DT40.

There are plenty of other experts that don't drink that kool-aid.

Is DT40 a good oil, I would think so, as are several others

[Gelbster]

"There are plenty of other experts that don't drink that kool-aid."
Where are these alternative experts and any posts on oil development for the M96 ?
We need as many as possible, I agree.

See Post 10 ?
This is just a list of oil companies that paid Porsche to have their product endorsed by Porsche. Very little tribology involved and certainly no mention of the M96.

They DO sell Rotella T6 !

Ok, here's a new game:
Whenever anyone asks about oil, tyres, cats, or the IMS, don't type a new reply. Just pick a favorite quote from an old thread and repost it:

Yes, you can use the Rotella T6. You could also use Joe Gibbs DT40, which is another excellent choice.

Just curious, what makes DT40 the benchmark?
