I filled mine to the middle of the cross pins. Just like setups you can't go by what works for someone else. It's going to take some testing to figure out what works for your track and driving style. I tried what I thought would be the two extremes in 1k and 10k and found 10k was better. I might go even heavier next time I race to see how I like it.

I believe you guys about the diff oil wieght, but looking back into threads, I thought many sc10 drivers thought 1k was too thick. They were going with 20w shock oil or black grease. 10K for outdoor and 3k for indoor seems thick in comparison.
How full are you filling yours. In 8th scale, I used to fill to the cross pins, to leave room for expansion due to heat. I know you can overfill them.
