My son has a Dodge pick-em-up with the new Hemi in it. He was out of town for a couple weeks and left me the keys. Also he left a note (and suprisingly, the MONEY) to get his oil changed. He takes it to a Pennzoil quick change place.
The Hemi in a 3/4 ton holds 7.8 quarts of oil. The tech at the oil change place didn't believe that. He insisted "NO ONE EVER BUILT AN ENGINE WITH MORE THAN 5 QUARTS". I showed him the manual. He said it was a misprint. After pouring in 5 quarts, he checked the level. Still low. Add one more. Still low. Add another. STILL low. Then Einstien pours in TWO more. Now it's OVER-filled. He drains some off. Too much in fact. Now we're low again. Add more. FINALLY. after emptying 10 quarts of (expensive synthetic) oil, it was at the right level.
I go to check out. Young Einstien has billed me for TEN QUARTS of oil.
The fight's on.
I refused to pay the bill. He kept threatening to "call his manager". My reply was, "What's his number? I'LL call him".
After an hour of debating the issue, the manager shows up. He's younger (and more Einstien-ish) than the tech. By now, I'm getting the story I insisted on pouring 10 quarts in the engine from the get-go.
After a while, I figured the bill WITH 8 QUARTS of oil, left the money on the counter and walked out the door.
Same place took a BRAND NEW air filter out of my daughter-in-laws car, replacing it with another. They said it was old and dirty. It was installed by my son, not 15 minutes before the car went to the oil change place. They got away with that one.
I'll promise you this much, they won't get another penny from my hand.
