I live in Austin. My '18 CRV EX has over 22k miles. I have no issues with oil dilution, AC cooling, or warmup in what passes for winter here. In winter, my car warms up enough to produce heat within about a half-mile of driving. I have no need to run in ECO mode when I get 32 to 33 mpg combined city/highway. All in all, I find it to be a very good car.
