The grade and viscosity of the motor oil you use is important, and if you drive in harsh conditions, we recommend multi-grade oil. If you're noticing a drop in performance, an engine oil flush for Buick Regal gets rid of the gunk and sludge and keeps it from affecting the fresh oil after you drain the old. It's especially important to clean your engine if you do a lot of stop-and-go driving. AutoZone provides the right products at the right prices, so you can rest assured that you're scoring unbeatable deals when you shop with us. Stop by your local store today and benefit further from free battery charging and engine diagnostic testing while you shop our incredible selection.
