    Engine Oil and Oil Filter Replacement
    Removal Procedure

    Important: In order to completely drain the oil from the oil pan internal baffling, the bottom of the oil pan must be level during the oil drain procedure.

    I've read the that oil REALLY comes outa there. Usually overshoots the drain pan. Also have read about people having different readings as related to the 6 quart fill. Most people will put in 5-1/2 quarts then check the stick. If stick shows full, the so be it. Believe the stick.

    Be sure to get the right number oil filter. There was a change. Not sure what year it was. Stay away from Fram.

    Lots of discussion. But can be overwhelming at first.

    I change it on my GPas 07 5.3 Avalanche, no big deal at all. Same as changing oil in anything else. Never Fram filters, ACDelco or NAPA Gold, nothing else IMO!

    The correct oil filter is ACDelco PF46 for the record.

    Advice I can give on changing the oil filter is that a lot of oil comes out when you take it off, so what I do is unscrew it little by little and let the oil run over the side. You WILL get it on your arm, so be ready. And yeah, the oil really does come shooting out of the drain plug, so I try to hold the pan right up to it.

    You can sucessfully use the PF61 as well...

    If you are lucky, look for the PF44 (short) & PF59 (long), those are the old GM mfg filters, whereas the PF46 & PF61 are made by champ..

    I've owned 2 1995 monte carlo Z34's (3.4L DOHC) and they both take just over 6 quarts of oil. Crazy.

    Actually that is incorrect. The dipstick is not certified by the department of agriculture as a scientific measuring device. Add 6 quarts if it calls for six, and where ever the oil is after that is you full mark. If you put 5.5, there is not enough oil. If you put six and its not on the full mark, then add more to get it to the mark, it will burn it off rather quickly and lead you to believe you are burning oil.

    on my 2003 Trailblazer- it says 7 quarts with Filter.
    I change oil and filter and simply refill with 7 quarts.
    where ever the oil reaches my dipstick- thats the full mark.
    And I do let my oil go about 10,000 miles- with very little oil use- almost no oil used.

    I agree with all your tips. The oil filter is very easy to get to from the drivers side. You might want to get a wrench that doesn't look like a cup though- mine slips alot. I also don't understand why the plug is pointed back vs down!! I always get some oil somewhere where it isn't supposed to be!

    6 quarts in it, and it uses a 46 filter, or you could use a 59, both work, and doesnt seem to change the amount of oil in the engine.

    easy to change oil on it, actually you dont even need jack stands or anything.

    uses a 15mm drain plug bolt.
    There are no stupid questions, just stupid people.

    Not to be contrary, but isnt it a 13mm? I just changed it today on my GPa's Avalanche, and I thought it was 13?
