I think all LG has going for them in this new product is their LXE wax esters and a compatible viscosity for Honda's P/S...

I think the LG PS fluid looks good in terms of additive chemistry for the older Honda PS spec.

Redline is using their MTF additive package for the PS fluid.

When did Redline reduce their PS fluid to a lower viscosity? Do you have an older VOA to show us?

oops, my mistake - was in a hurry to get to work when posted

apparently I was hung up on their website's description of "Lightweight fluid avoids power loss"

the Red Line PSF VOA from 2017 matches the current manufacturer's specs:

Honda's need a better cooler for their steering fluid. The ones that still have hydraulic steering that is.

I'm bringing this back up because I finally realized that this does _not_ match my UOA of Honda PSF P/N 08206-9002. Here is the viscosity I obtained after 14,000 miles of use in my Honda pickup. There would have been a small amount of Red Line PSF mixed in from before the swap back to Honda:

cSt @ 40C = 37.5
cSt @ 100C = 10.0

Can anyone comment or elaborate on whether Honda changed P/N 08206-9002 PSF since 2017?
