This is a fantastic tool I found for calculating viscosity at ANY temperature. One thing I always hated about the oil data sheets is they only give you two cSt viscosity, one at 100C/212F and the other at 40C/104F. But that tells you absolutely nothing about your oil viscosity at 10, 20, or 32 degrees Fahrenheit or even -20 and everything in between. The standard oil data sheets don’t have the cold morning calculations, and now that I know our 4Runner have an oil cooler this will be a really good tool with helping explain a future post.
