Q: With gas prices being so high, is there any advantage using the premium unleaded gas when not required for any vehicle?
A: That’s a loaded question for many reasons. First, engines that are designed for the premium unleaded will perform best if they use premium. In some cases the use of premium gas in an engine designed for regular gas can actually cause hard starting and hesitation when started in cold weather. In other cases the use of premium in some regular gas engines can give the engine some added boost in power.
