HELLO

I have a jato 3.3 i run it on and off road but mostly on road racing in a parking. We kinda made a course that has a couple turns and some straight aways.
I was wondering what differential oil weight should i uses. I want to be able to get some better tration but also make some pretty good turns.

Thanks for any help

I think 30,000wt is stock. I have 60,000wt. Its like honey. locks well and still turns sharp
