2004 Overland Oil Change - 10W30?

Had Jeep dealer perform oil change today on my 2004 GC Overland. Parts listed as follows:

1 PK5281090 Oil Change Kit
1 5281090 Filter EN 9057006
6 68026603-AA Penzoil 1081090

Is that oil the required (WJjeeps) 10W30 for the 4.7L HO? Manual lists 5W-30 for both 4.7 &4.7HO. Will call to confirm tomorrow, but any clues from the part number?

As much as I don't trust the dealers for prices, I can't see them putting the wrong type of oil in their own brand of vehicle.

I m being told by the service rep they put in 5W20 "as required". Should I be heading into the service manager to discuss?

in general the first number is the weight of the oil when cold, so you really want a lower number for winter while the second is the weight when hot, which some believe you should not go down when changing and be cautious when going up. The 10w30 is most likely fine, I personaly switched from 10w30 to 0w30 and my jeep is running better. It's less stress on the engine during start up and the same at running temp.

So, is the 5W20 they evidently put in a problem? Should I have it changed to correct?

Look at your manual. It gives a chart with 5w30 or 10w30 (the 5 goes to a few lower in the temperature range). Last time I tried putting in 5w30 conventional, the engine had big issues. I'm sticking to 10w30 synthentic. I'd suggest 10w30.

Called northpoint jeep today and they said 5w-30 has always been used in my 04 4.7 HO overland. Looks like my owners manual was right.

I will be vigilant at next oil change and insist on 10W30, but is the fact they just used 5W20 a potential problem for next 3K miles? Not trying to be over thinking it, but I would like to drive this Jeep for a long time and am willing to take care of it in exchange for a long life with it.

IMHO you should be fine. Winter is starting to set in so you shouldn't see high temps. Oil pressure once warmed up may be a few #s less, but that isn't a major issue. If you do a lot of highway cruising, keep an eye on the oil level to make sure it isn't "consuming" some of the thinner oil.

My dealer did the exact same thing to me a couple of years ago -- 5W20 in a 4.7 non-HO going into the heat of summer. No problems.

It will be just fine. A lot of newer engines use 5w-20 even the Fords LOL. My WK2 5.7 uses 5W-20.

Yep 5w-30 is the recommended viscosity range in all 4.7s made before 08. 10W-30 should be fine in hotter climates but colder climates should use either 5w-30 or 0w-30 in the case of below freezing temperatures.

What issues? im curious.

In general, any engine can use a veriety of oils, but only as long as the chosen one stays consistent from the start and only gets heavier (on the second digit) switching an older, leaky engine to a lower weight should have some problems, as the oil will be more viscous and seep through smaller holes than the heavier one could.
The first number should have no impact on running temp oil viscosity.

and i cant find the article i learned this from so you are going to have to do your own research, which I recommend you do. Don't search what oil goes in your jeep, figure out why the numbers on the oil matter.

One of the differences between conventional and synthetic is that synthetic molecules alre smaller and it can therefor get through cracks a conventional couldnt. some people say that synthetic made their engine leak, which is definately not true, the synthetic just made dormant symptoms more visible. In which case you can just switch back to dino oil. Not all synthetics are created equal. Figure out for yourselves which is better and which one sucks.
