Just got a 2008 CX-9 AWD. I know the fluids need to be 80-90 and 75-140. But I'm having trouble finding them without limited slip additive. I looked at the ford motorcraft ones but I'm not seeing the API gl-5 on those. Anyone know if it's ok to run these fluids with that limited slip addative in there? Or if I can use 75-90 instead of 80-90. The 75 just seems to be a lot more common.
