Understanding manufacturer oils

[Bushmonkey]

Hi all. I'm looking at grabbing the oils I need to build my new car. In my manual (kyosho) its recommends shock oil #450 which takes me to 450wt oil and #7000 diff which just says sil7000.

 

Is the 450wt actually 450wt or 45wt???

 

I've read a graph about how losi have their own ways sometimes, my traxxas is simple wt 

 

It's a 1/7 scale 2wd buggy

 

Need to get them ordered today ready for the weekend. Thanks in advance guys

The viscosity between brands is slightly different so a direct comparison is not correct, but close enough. 

 

There also is not direct comparison between WT (45wt) and Cst (450cst). They're different ways of measuring the viscosity. 

 

Generally, you'd choose a brand and run that and just use their fluids so you can say 450cst was too thin, I'll try 550cst of the same brand for slower dampening. 

 

Associated shock and diff fluid has both measurements on the bottles for reference.

Cheers @Derka. in your opinion, which oil would be somthing in the middle?? This is the 1st time I've built a car from scratch.

 

Just looking to get it running, I'm happy to change oil later, but need middle reference if that makes sense. For diff and shocks

I'd personally go with what weight/cst fluid the manual suggest and then tune from there.

 

There is no one correct answers as it depends on surface, grip and whether just bashing or racing?

On a 2wd buggy, I'd keep it soft. Start with 45wt at the rear, maybe slightly higher up front. Then work from there. 

 

I started with wt, so that's all I know.

Ok good stuff. And 7k diff oil???

[Derka]

Yeah 7000cst in the rear gear diff would be a good place to start.
