7 year old Mobil 1 oil, looks fine, change?

To the OP. This is a joke right? Just trying to see how many forum members are stupid enough to recommend you not change it? Why anyone would even consider not changing the oil and filter under these circumstances is absolutely amazing. Most oil manufacturers list the shelf life of new oil in UNOPENED containers as 5 years. There was a car collector on a forum I used to frequent that actively sought and bought barn find classic cars. Just for the fun of it, he had UOA performed on the oil in a car that had been sitting for 25 years. The oil checked out OK. Just another example of why I consider UOAs to be a supreme waste of money.

Exactly,ridiculous advice to leave 7 year old oil in any car. Original poster,do yourself a favor and change the oil and the filter. There is moisture in your oil.If you do not change the filter,you run the risk of parts of the media breaking off blocking critical passages.

Dodge gave me a nice pair of boots to take a test drive in that vehicle.
Change the oil and all the fluids before any real use. If for nothing else to get a better look at all the working systems. The brakes would be a very iffy thing after sitting that much.

Oil is probably ok. I'd be concerned about the filter
Photos, as requested. It's a 5 speed manual, cruise control, has AC (not working, but all components there, so hopefully just a charge). No power steering.
The bucket seats are actually quite comfortable. It also has a 1980s era cargo cover that is easy to fully remove, and also locks down. The shifter is floppy. But I googled, and on the Omni forum it actually seems like a fairly common issue. There's even a kit made to correct it.
And, if Wikipedia is to be believed, it's actually half-ton rated.

LOL. Part of the appeal in getting it was just how different and weird it is. I do wish mine had an original two-tone 80s paint job with all the decals.

I drove it home, well over an hour on the freeway, and have driven it around town a bit, on the oil it has. I am intrigued by the UOA suggestions.

I wish EVERYBODY would realize that.

The oil probably checked out OK because the oil was, in fact, OK.
But if you prefer your opinion to facts (and who doesn't?) then facts obviously have no value.

Seems to be worse than that. This keeps coming up, so here it is again.

Its titled "Lubricant Storage Life Limits - Industry Needs a Standard " but if you read it you might reasonably conclude that "industry doesn't need a standard", since they don't appear to have one, nor any basis for one.
Like most "pitches", what it doesn't say is as significant as what it does. There is absolutely no evidence reported here for on-shelf deterioration of motor oils. Instead, its served up as a ready-cooked "given" with a side order of "The sky is falling" Chicken-Little panic salad.
They survey industry recommendations. Table 4 (recommended shelf life for indoor storage at 20C) is especially instructive

1 year (!) isn’t very long, and 1 year to infinity is a pretty wide range. I think you could say there's a certain lack of concensus.
IF the 1 year has a basis in fact, it could mean that the major oil companies massive (but of course secret) testing of their latest oils, extending over several decades, has told them that their oil is particularly fragile.
OR it could be that their general knowledge of the chemistry of their product makes them think it might be particularly fragile, though its odd that the PAO, plausibly believed to be more stable in an engine, is just as fragile on the shelf.
OR it could be that they wanted to cover their big fat corporate arse, and pulled the smallest number out of it that they thought they could get away with, assuming no one would notice that it was completely unbelievable.
(One might also conclude that either the re-stocking (or re-labelling) costs associated with this short life are carried by the retailer, or the supplier thinks closout specials are good for bizniz.)
Perhaps I'm too cynical, but I've found its actually quite difficult to be TOO cynical, and often quite an effort to be cynical enough.

Yes, you can tell it's not their car we're talking about.
Working on my 3rd year on oil in the jeep, no intent to change the oil until miles have racked up enough to change...

Cool truck, nice catch
I'm right there. No cold separation, no high condensation issues, I'll bet that oil is quite good
I left the syn-blend in my BBC Chevy truck for 5 years because it just ran a few thousand a year. After 5 years it had 7,500 miles on it and looked it. Out it came. If this oil has less than 3K, it should stay. Garage queens are special cases as far as deterioration of anything
