You can use linear interpolation on a linear log graph (temperature linear X axis, viscosity Log Y axis). Someone is bound to show it later in the thread.

I agree with Patman...only 158F?

I believe most engines typically run closer to 100C (212F) Your oil temp should typically run the same or higher than your coolant temperature.

I studied some rheology in uni a few months ago, and its very obvious in the lab that oils do not display linear behavior when it comes to viscocity vs temperature. More like exponential or sigmoidal in some cases. So no, a direct interpolation will not yeild accurate results at all...
