Being 75, sick, broke and driving just a few miles isn’t the issue. Maintenance is maintenance.

I say go for it, it will be fine. As for the tires if they are less than 10 years old I wouldn't worry about them. I have had tires older than that with no problems, look at the condition, if they are cracked or weather checked then they need to be replaced! Most tire companies say 10 years if they are in good condition. On edit. I missed the 10000 miles on the oil. I wouldn't drive anything 10000 miles on an oil change whether it is synthetic or dino. I think that is just too far! I would say 5000 with syn oil. 3000 with dino oil.

I can't see how anyone can say it's OK to put 10K miles on that engines oil without knowing waht exact eng and year it is. A lot of Cummins engine didn't have anything near a 10K mile oil change interval.

As far as the acidic thing and old oil, I don't buy it. I once let an old car (1964 Thunderbird) sit for roughly 6 years and then I rebuilt the eng. The bearings didn't show any signs of being eaten by acid.
I can see the reasoning behind the theory but in pratice it doesnt seem to be an issue.

Normally I'm not a fan of testing oil, (in lieu of changing it) but in this case, he could spend +-$40.00 and have the oil tested by a lab to see if it's fit for continued use.

Or there's the oil blotter test using a clean white business card for free.

I would at least change the filter. if there was any moisture in the oil it could have caused the paper to deteriorate in 5 years. acid in the oil is'nt the problem that it was in the past due to ultra low sulfur diesel

I know very little about synthetic oil, just wondering does synthetic age or break down with age as much as real oil?

Use the oil but I’d worry about the tires.

I sent my oil in for analysis after ~4 years and 14,227 miles and it was still perfectly fine and I could have left it in there.

My oil is going on 5 years and last year I only put on about 350 miles. Blackstone labs says to keep going as the oil is good and I am running Dino, not Syn. I would not worry about it especially for the short haul though I would put enough miles on it during the moves to get the engine and oil hot, maybe a 30-45 minute drive on the highway and not city streets.

I would be more concerned about the tires sitting for so long than the oil. I would forget about the oil and drive a little slower than normal to get to the destination. Of course you want to make sure that the tires are properly inflated with maybe some extra to keep them cooler. After the engine warms up it will burn off any moisture that has gotten in to the oil.
