manual gear oil suggestions?

[jhandy]

I was going to change my gear oil in my 2002 S manual this weekend, but I can not seem to find two people that agree with what to put in there.

the car has 65K miles and I drive in south texas heat.

What brand and weight oil would be the best regardless of price?

Also does anyone have a DIY link for this?

thanks,
James

Call Sunset (503-641-8600) as they usually have a little better pricing:

There is a basic reason why you cannot get agreement on what type of gear oil Porsche uses; because they use a totally unique product that is made just for them. As the result, most major gear oil companies (the truthful ones anyway) simply say they do not have a suitable replacement, while the hucksters will tell you theirs is a perfect substitute……

Knowing how much these gearboxes cost, and that the OEM fill is a readily available and inexpensive full synthetic product, going to Sunset and buying the OEM fill is your best bet.

There has been a lot of postings on oil and some are pretty comprehensive. I remember reading a great one by Charles Navarro on why he does not recommend oil but if you go to LN engineering's site you will see what they think is good enough to distribute.
I replaced mine recently with Royal Purple and ran TTs, AXs and DEs without any noticeable difference. (I'll try Motul next).
For the DIY, Bentley's is your best help. Not too bad of a job (Except measuring the oil level).

What???

Jhandy is asking about manual gear oil....not engine oil. And yes, Charles clearly recommends specific oils on his web site. Did you read his entire "Freq. Asked Questions" link? Excellent reading. You will see that he recommends specific oils, and recommends oils to shy away from (like Mobil 1).

The OEM fill on race cars from the factory used to be (and might still be) Mobil 1 SHC, which was rebranded under their industrial lube name Delvac 1. We've used it for years, when it was only available in 55 gallon drums. I used to even bottle it for customers, until Mobil started offering it in gallon jugs. It's different from the M1 gear lube found at Autozone, etc., and I've used and recommended it for years.

Charles, an interesting response, particularly in light of the fact I had read the same explanation elsewhere and asked our Mobil rep about it some time ago, got a totally confusing answer and then was referred to their “technical group” who responded, “Mobil no longer produces a suitable gear oil for the Porsche transmission. You should consider contacting a Porsche dealer for an appropriate replacement.”

Any thoughts?
