I took my truck in today for a free oil change (I had a coupon) and to check my brakes. I really expected to need at least front brake pads because it has been around 6 years since I had new ones and they were making noise. The place was swamped with customers on this holiday weekend and they were turning away all walk-ins. Luckily I had an appointment but had to wait 30 minutes for the shuttle driver to get back so he could drive me home. Just as I was leaving with the shuttle, they brought my truck in to the bay. I got home and they called me 10 minutes later with the prognosis.
They said my brake pads were still ok and only made noise because they were low grade. They recommended upgrading to ceramic pads. I said thanks I'll do that later when I actually need to replace the pads. Then they said that the air filter looks really bad and there may have been some pack rat activity in there. Ick. I hate pack rats. I told them to replace the filter and do the oil change. An hour later they said it was finished and I asked to have the shuttle pick me up. TWO HOURS LATER! the shuttle driver showed up. I wasn't expecting to spend my whole day without a truck.
Later, as I was paying I remembered that the air filter is not included in the oil change. I probably could have handled changing the air filter myself. The total for my free oil change and air filter? $24.90. Ouch. They charged me $19.99 for the filter. I looked it up on the Checker auto parts website and I could have bought it for $12. And the Checker guys probably would have told me how to change it. Oh well. I learned my lesson.
