I’ve been using the cheap gas for years. Why use high-test for my equipment now?

Engines manufactured since 2008 have had to meet increasingly restrictive EPA guidelines. As a result,equipmentis nowrunning much leaner than older equipment. It doesn’t take much to knocka lean-running engine off kilter. 93 octane gasoline is cleaner and has additives that the cheaper gas doesn’t. As a result, your engine will run more smoothly.
