UOA is in kilometers not miles.

Switched to Red Line CVT. Previous fill was Amsoil CVT.

A ton of owners on the HRV forum are reporting transmission failure with mileage under 100k because the fluid isn't changed regularly and the belt fails.

I'm going to keep changing it every 6 months from here on out.

I think every 6 months is excessive, I'd do it every 25K Km.
Even once every 25K km is too soon IMO it should be every 40-50K Km, but still cheaper than a new tranny.

I think for the environment and type of driving this car does, there's a chance the viscosity might be too thin if doing 40-50k km.

If you look at sample 1, the OCI was 28k km and the viscosity at 100C was 5.1 cSt

According to an old UOA from Blackstone, they said cSt at 100C should be between 5.1-7.9.

As I have stated before a CVT shears oils much more than do manual and step-shift transmissions which is why I recommend more frequent fluid changes than for manual or step-shift transmissions.
What would be a good starting point in terms of frequency? I tend to do the CVT annually because it’s very easy to do and the fluid is cheap.
