Valvoline makes three fluids (at least) that will work in the power steering system of my wife's '02 Corolla: MaxLife Dex/Merc which is a synthetic and obviously has all the high mileage additives, Import Multi-Vehicle which just seems like a synthetic Dexron-compatible fluid, and regular Dex/Merc which is a dino Dexron-compatible fluid.
I know using MaxLife in power steering systems has generally proven to be fine if not recommended. I assume the high mileage additives either help somewhat or do next to nothing and that the fact that it's a synthetic fluid is what makes it 'good', but it is a bit thinner than regular dino Dexron according to the product information sheets. The Import Multi-Vehicle is a synthetic but has very close to the same viscosity as regular Dex/Merc. So is the thinner MaxLife not really as good an option as Import Multi-Vehicle if I just want to use a synthetic Dexron fluid? Will the fluid viscosity change how the system works for better/worse?
