OK. First--I did a search under the backyard mechanic and here and only found "how to change oil" posts.

Here's my question: I Had an oil change done. I questioned the mechanic as the Nissan owners manual states 3.5 to 3.75 quarts of oil. They put in almost 5! They checked the dip stick several times and this was a few hours later. Oil levels were fine. I showed them the owner's manual and they were adamant that in their experience, there was no way a 6 cylinder could only take that little oil. They said that the manual was probably generic and referring to the 4 cylinder base model. They even called up the service area of the local Nissan dealership and asked--Nissan dealership told them 4.8 quarts!

So, given all of this, plus the fact that the dipstick levels were fine--am I in danger of blowing the seals and doing something bad to the Xterra? How is it that ebven the dealership stated that it used 4.8 qts instead of the 3.5 recommended. Any thoughts? I do not want to risk damaging this vehicle. The same place that did my oil change is the place I purchased it from (who did an initial change prior to purchase) So I must have about 4,300 miles on this with that much oil being used.

Any help or insight appreciated.
