Fraud at Jiffy Lube

It can happen anywhere. Not just China-Mart and Jiffy Lube.

back in the 90s I had a Nissan mini truck. I took it to the dealer to get my free oil change form buying it. I took it home when they were done, only to find that I had no oil in it when I reached the driveway. The oil light wa son. I get out, and see a trail of oil down the street. I open the hood, and check out the filter. the filter was tight, but I noticed that the outside edge of the filter was smaller then the mating surface on the block. I called one of the guys at my shop and he ran the numbers on the filter in a catalogue, sure enough, the goober at the Nissan dealer slapped a V6 filter on my 4 cylinder engine.
