I found this interesting. Had my oil changed last Thursday by the dealer truck was purchased from. Saturday morning I noticed a patch of oil on my driveway. Filter was loose a full turn! Estimate about 1/2 quart lost and the instrument gauge showed 2 bars from full. Took the truck back in to top off what was lost. After service department "checked" the oil, they decided to do a completely new oil change. Not even your dealer trusts the instrument cluster.
