:angry: After doing oil changes myself I had a Firestone dealer do my last (40000). I had bought tires and was offered a free oil change. I asked them to put in three qts. and give me the 4th. qt. They said they could not do it as they have the oil in a bulk container. I asked them for the old crush washer after changing oil, they countered with, Oh, we use the same (old) washer! I was shocked. They do this on all cars. I checked my oil, they had topped it off to full. ( I looked at the carb throat and it looked OK ) So I got away clean there. On my tire purchase I asked the dealer if the bead pressure was the same on the new tires? ( 44 lbs) They said yes, so I had them at 44lbs! Again I was shocked to read the tiny print on the side walls that the bead pressure was 40 lbs. So I had been running 4 lbs over bead pressure! The sidewall warns that overpressuring (over bead) CAN cause an explosion. Fortunately there is apparently some fudge factor there so no problems occured. Aside from the possibility that the center tread has been slightly more worn for the last 10000 miles. End advice is never trust the guy who is working on your car or the Mgr, UNTIL verifying every single detail. Change your own oil.

The washer is made of some type of fiber and it compresses to assure a tight fit. I wanted it as proof they had changed it. Truthfully, I have been using the original washer for eight oil changes now, I always check for leaks tho. So......maybe the professionals know what they are doing.

The new oil makes it real difficult to read the dipstick while older oil is much darker. The crush washer is a craps game. On my other Toyota I have changed or forgotten to change it for the seven years I have owned it wthout a leak. As long as the drain plug doesn;t leak you are OK. If it does leak it's a pain since you almost have to chage the oil again or buy a new plug in order to quickly switch them. Or you can get a "helper" to plug the whole with a finger while you switch the swashers.
