Did you all know that Huber does free oil changes on all GM vehicles? That's including Chevy, pontiac, oldsmobile, buick and GMC. No strings attached, and you didn't have to buy your vehicle there. The oil changes are supposed to last for 7,000 miles. Just thought I'd share since we've been going there for awhile now and loving free service. Oh and they rotate your tires for free too. They are great!
