Has anyone heard of non-detergent gear oil? Motor Meister recently rebuilt my 5 speed for me and requested I break it in with non-detergent 85-90w gear oil. I have looked all over Houston and I cannot find it. Any suggestions? Who makes it, who carries it?

Thanks,

Stephen:

I'd suggest that you get a gallon of Swepco # 201 85w-90 gear oil.

Thats everything you need and no "break-in" of that tranny is required unless something is wrong with the internals.

Gear oils are rated by their EP index from GL-2 to GL-5. All Porsche trannies need a GL-5-rated lubricant to handle the high stresses on the ring & pinion gears.

BTW, detergent and nondetergent oils really applies to engines which must deal with the byproducts of combustion; something not found in transmissions.

Thanks Steve. That is what all my race friends said as well. I am just paranoid and especially after reading all the posts about MM on other forums.

I just hope I have few problems with the rebuilt engine and transmision.

Thanks again,

I too, hope that you do not have any problems as I've seen 3 MM engine jobs here.
