Yes, no problem. The blended oils are rated that way to indicate they will function in varying temperature conditions (i.e. summer/winter), with the high value associated with high-temp/reduced viscosity and the low value reflecting low-temp/high viscosity (hot and thin vs. cold and sludgy). Thus, the more extreme-range oils would be good for colder climates, such as the northern region of the U.S. In your neck-o-the-woods, 80/90 is plenty-fine... <img src="/forums/images/graemlins/kewl.gif" alt="" />

I figured 75-90 or 80-90 was fine. We do hit negitive temps in Kansas City.
