hey guys, i just want to update and keep this thread alive.

i stopped at the dealership today and made an appt to get the oil changed next Thursday so that they can monitor my VX for oil consumption.
they're gonna check a rattle that i have as well as the EGR tube, etc as well.

i had a conversation with the Isuzu service manager for awhile and he said some interesting things.

1.) He said the VX takes 6.2 quarts of oil. I told him it takes 5 and he told me i was wrong. I made a copy of both the owners manual page and the page in the service manual where it says 5 qts with a filter change and I will be taking them in to him on Thursday.

2.) He told me that he wouldn't use anything but an OEM filter and went into some "scare tactic" story about filters blowing up because they're the wrong size.
I was waiting for him to say something about "voiding the warranty" but luckily (for him) he didn't. I told him that I think the Purolator Pure One filter is just as good if not better than the OEM filter. Does anyone know who make the OEM filter? He started saying that the OEM filter has some feature that the aftermarket ones do not, but couldn't remember what it was and said he would ask the Isuzu tech on Monday.

In regards to #1, I am very concerned. If they put 6.2 qts, it will be way overfilled. Then I come in after 1000 miles and they check the oil level it will probably be on "full" since it started way above that and then used oil down to there.

I don't care what he says, I know how to change oil and if i put in 5 qts and run the vehicle and then check it and the oil is at the full line, then that's what it takes. Anyone have any opinions?

I'm gonna call Isuzu on Monday to see what they say the VX takes with an oil and filter change.
If they say 5 qts, I will make sure that the dealership does not put more than that in.
