Can we get a chart made with all of the factory oil weights made for the vehicles? This way if we want "Thicker" we know our starting point.
Great Idea!

Thinner than what? Thicker than what?
It depends on how you want it to handle. The manual will give you a starting point. It tells you what is already in there and you can go up from there Kind of up to your driving style really. There are a lot of threads on this...

Thanks for taking the time to reply.
I'm feeling really stupid, I can't find the threads, and have the manual in my hands right now and can't find a spec on what kind of grease to use. I drive a fair mix of high speed open field blasting, rocky dry river bed/ moderate climbing, pretty tame jumps, drift being used the least.

Have you heard of High Temp Green Super Lube from Hot Racing?

Here's a useful chart to help you choose what weight thickness you should use your front, center and rear diffs.

Just got my first RC in over 25 years. Can you recommend what diff oils to use on an Arrma Kraton for keeping the power to the ground and hard dirt track racing? Also I am using it on 2 3S batteries, should I try 4S for more control? Thanks

Most here start with 100 cst in the center and go from there.

Hello there! I just have a few questions in my mind for my granite mega 2wd truck.
1. What is the stock weight of granite mega differential oil?
2. If it is a 2wd, does that mean that I only have rear differential and not have center and front diffs?
3. When do I have to change my diff oil and shock oil?
4. Is it okay to use a 3-in-1 oil for lubricating gears and other movable parts instead of grease?
5. What brand do you recommend for a cheap diff oil (and specific weight), shock oil for both rear and front (and specific weight), and also grease ( or is it okay of I use the 3-in-1 oil?)?

Thank you very much for your patience in answering!

Regards,
Ces'tLaVie

1. As a guess, I'd imagine it was like my Kraton and filled with machine grease (approx. 1000cst) - Consider cleaning out and replacing with 30k-50k cst silicone oil.
2. Yes.
3. When they break, leak or you want to change the driving characteristics of your car.
4. Not really. It's thin and will be flicked off and ultimately only provide lubrication for a short period of time. Also, mineral oils and petroleum products aren't great for rubber o-rings and seals.
5. For all oils and lubricants on an RC, I'd suggest using silicone-based oils. Diff oil - 30,000 cst - 50,000 cst. I use Team Associated oils because my hobby store sells it. Shock oil - No idea - Guess at 700 cst?

Also, for #4 - don't use any lube on the pinion/Spur. Same for dog bones/drive cups. Run them dry. For the gears internal to the gearbox, use white lithium/moly grease. Inside the diff, use the Silicon diff oils. 3-in-1 is great for bearings, though.
