The Ford Barn - View Single Post - STP and Transmission: any negative experience ?

Hi

Before you hate me this isn't a thread to ask about the best oil to use in the model A transmission. There are many searching this forum.

What I would like to know, is something simple.

Those, who are using 100% STP in the transmission have experience any negative point ?

Like :

have the external temperature affected the viscosity such that it was not shifting smoothly ?

Or have you experience any other issue that make your mind change, regretting the use of STP ?

Or....you got the idea.

We do not need to enter in another discussion of all the 600 W oils that can be used. I have read them almost all.

In those threads I have NOT read anyone saying something bad about using 100% STP. Because the threads were NOT pointed to get that type of comment, then here we are.

To 100% STP users:

Are you happy with the results ?

Anyone stop using it ?

Will I regret my decision of using 100% STP in my transmission?

Thank you !!!

Cheers
Forddan
