Hello,

My son and I are building a car and have a question we aren't sure about. This group has been great helping and getting him going so thanks in advance.

Below is where we are. We didn't get differential oil in the kit. Is this something one has to go and buy? We have some 3 in 1 oil around and will this work or is it something different? ( I would assume so) If different, what can one use and where can one purchase it?

Being new it is likely I cannot upload an image yet. We are building a PR S1 V3 FM SPORT 2wd Buggy kit and the spot in question says:
The recommendable density is 3000-5000 differential oil, please pour in the differential oil earched up to 80%

Does this also mean we fill this 80% full of the differential fluid?

Thanks again.

You should be able to get it online or at your local store if its open .
Not being familiar with your model , I would follow the manual regarding oil weight . And yes , 80% full sounds about right .
AMain does some good videos on youtube , the one on changing diff oil should explain everything for you .

80% full means that they want you to leave space for the planetary gears to fit, I simply install all the gears and wipe the fluid flush to the back of the gear like this so it's 100% full with all gears installed:
