Hey All,

I hope this is not a redundant post. But, the Porsche Classic dept just recently released 2 different grades specifically designed for all air-cooled Porsche engines. Hopefully I've summed it up correctly:

Mineral based 20w-50 (All engines up to 3L in displacement)
PAO based 10w-60 (All engines 3L and above)


Info directly from Porsche:

What is of more interest is:
1) What specifications must these grades meet?

2) What grade are you using now?

3) Are you/why are you interested in changing grades?

I have no reason to use either of these. This was merely meant as an FYI and to start a more in depth discussion on these two different oils.

If an in-depth discussion is what you would like, why not answer my other two questions? Or do you want the rest of us to discuss this while you sit silent on the sidelines?

That's what I was thinking. More garage art.

Oil Changer, I think the OP is bringing up some news he believes will be of interest to some members. He doesn't necessarily have to conform to your concept of the ideal post.

You don't need to guess. He came right out and said he wanted an in-depth discussion. Crazy for me to think he wanted to be involved in his own post, ha?

Many thanks to the OP for posting. Great info!

The snide comments, however, mystify me.

Thanks for the post.

Too bad they haven't posted any specs. I'd be curious to see how these oils compare to any other 20w-50 or 10w-60.

Very interesting!

Now that I've found the perfect oil, I'll have to start searching for the car to go with that oil...always been "Porsche-curious"...

Cheers,

Oil Changer, good lord man! Just thought folks here might be interested to see this.I know nothing about this oil, other than what was on the website. I thought this would be a relative post for others who might be interested. To answer your 3 questions:

1)No freaking clue

2)M1 0w-40,T6, TGMO. Look at my sig and figure it out for yourself

3)Not interested in changing anything.

Give the guy a break. He posted what he could find, in hopes someone else here may have more info on these.

I liked the details provided of why these heavy, lower detergent oils may be more suitable in the referenced older air cooled engines. The comparison to a 0W-30 was interesting (there isn't a 0W-30 on the A40 list) having a more optimum cold start behaviour but it's use could result in leaks, higher oil consumption and lower oil pressure due to the engine's higher production tolerances.

I have a friend with a '72 911 with a rebuilt engine and he has no problem maintaining sufficient oil pressure on using M1 0W-40.
Previous owner was using 20W-50 even after the engine was rebuilt, as most owners of air cooled Porsches do.
The engine runs so much better with the lighter higher VI oil.

My advise to owners of all older cars, is to take advantage of the advances in modern lubricants if you can. If the engine hasn't been rebuilt, is loose and consumes a far bit of oil then sure run a 20W-50 or a 15W-40 if you can maintain OP, but once an engine has been rebuilt use a modern light oil.

Hi,
ianj3vr6 - Thanks for the info

These lubricants (viscosities) are what the Factory's Museum in Zuffenhausen uses!

Previously knowing some of the people there including the Director I can assure you they know what they are talking about...................
