Places like Midas and such are not to be trusted any further than you can throw your car (my view). A quick way to do a check is to take it to the place that uses the oil that you want. Say, Jiffy Lube for Pennzoil. They, like the dealership will do all the extra checks...whether you want them to or not. This is ok...just remember that YOU want them to do ONLY what you brought the car to them for..NOTHING else. So they come in and tell you this is low or that is low...and to give them a little credit, they may be right. Like the oil level may be a hair (I am not kidding...a hair) below the full line. Then you say top it off, they add a tablespoon and charge you for a qt. I think enough of the TV networks have done exposes on these shops to at least warrant you being extremely careful. So back to the inspection. Let them go through the trouble of removing your cabin filter (Yes, most of you have them) and they will show you all the leaves, etc that are on it. Tell them no, you don't want it changed at this time. Good answer for everything they say. Next, when you get home, you can top off the fluids, etc. You can go to Advance and buy a cabin filter and if you don't know where it is, just watch when they go back after you say no, and see where they put it. Believe me, it is cheaper to spend 5 minutes changing it out than it is to have them do it....a lot cheaper.
