What grade of oil should I use in my 2004 GMC Envoy....10/30 or 10/40 and how many quarts if changing oil filter?


The oil recommended by the manufacturer is 5W-30. You will need 7.0 U.S. quarts or 6.6 Liters

Bought the envoy w/ 70,000 miles, fresh oil change. @ 74,000 miles it was 1.5 qrts low, put in 5w30, checked oil 2 weeks later it was 1 qrt low. do not see smoke or any leaking.


I just bought a 2005 envoy too. I read in the manual that the 4.6 6 cyl engine needs 7 qts total. 2 Over the normal oil change. Is it possible it wasn't low to start? I noticed when Walmart changed the oil they charged extra for the change because it needed the two extra qts. However my dip stick has oil over the full mark. Seemed strange but I haven't had any leaks and after 3k mile no change in level. Make sure you had the correct about the first time.

Warning light come one and oil pressure gauge goes to zero. could this be somthing other that the oil pump ?? how hard is oil pum to change on 2005 envoy xl ?


check oil sending unit first. could be that it has failed and is sending a bad signal to the instruments. if it is the pump the engine has to be removed to change the pump.

2004 envoy sounds as if it has no oil. no oil lights are on though. where should the oil pressure gauge be ? the need is in the middle. It sounds as if it is riding hard. I remember a car I had that...


The Envoy's oil pressure gauge is not showing actual oil pressure, the computer calculates the reading based on engine RPM and the on or off signal from the oil pressure switch. You need to first check the oil level on the dipstick, than have a mechanic put a manual oil pressure gauge on the engine to read the actual oil pressure.

Oil pressure low ,stop engin this message appear in computr car envoy 2003


Check oil level via dipstick , if it is full check oil filter is not blocked (You need to have a mechanical knowledge to do this ) if both ok then oil pump is on its way out or there is a blockage in the engine oilways

Where is the oil filter on an 02 gmc envoy


under vehicle, passenger side, way up pass the frame, closer to front of truck, hard to get out.
If not there, look for a panel near bumper with 2 bolts, filter behind that.

My 2003 gmc envoy oil pressure keeps going up and down while i am driving. i recently just changed the oil.

RE: Oil Pressure going UP & Down!

I'm going to assume you had someone or a shop change your oil.
If you did I would immediately take your car to another place as your oil gauge should not be doing this. Worst case is you have an oil leak so check your oil immediately and add oil if necessary before driving.
Most likely someone put in the wrong oil filter and your oil is having trouble circulating since this is a fairly new car!
Also, if your oil was overdue a change.....have it changed again to clean it up as this could just be it's still dirty and clogging the new filter.
I wouldn't worry too much if your oil dipstick is showing it full!
But do a follow-up asap!
