Soaring temperatures put a major strain on your vehicle’s fuel efficiency. Many drivers assume that warm weather improves fuel efficiency, and in some cases, that is true—engines reach optimal operating temperature faster, and cold-start inefficiencies are reduced.

In this month’s blog post, we review what vehicle owners need to know about how hot weather affects fuel efficiency—and what can be done to minimize the impact.
