You might consider a "crack filler" that is more of a mastic than hard cement.
Look on Amazon where people rate the stuff.
If you could somehow grind or cut so bottom is wider than top that would be good.

How much does FlexSet cost?

From what I've seen Caltrans uses a rapid-setting resin that's the only stuff to hold up well for patching concrete cracks and potholes.
(I don't know much about crack filling. I've tried a few times, and that's it.)
Eh, about $100 for a 5 gallon bucket.

Joints are put in concrete to try and control where it cracks.
For the patch, I'd just search home depot and amazon for product reviews. Some two-part epoxy / or urethane should be a good bet - but I haven't looked into what's recommended.

Experts think that the concrete at the center of the Hoover Dam still hasn't cured after 75+ years, despite the network of water-cooling tubes they ran through it.
If the crack opens and closes with temperature or ground moisture, you'll need something flexible. Otherwise you'll force the crack further apart.
A smaller crack can be directly filled with epoxy, but that's a pointlessly large expense with a 1" crack.

Not the Hoover, but my great grandfather was one of the designers on the Grand Coolie Dam. The water tubes were there to pull the heat away from the cooling cement I believe.

I believe they also used ice in the concrete to cool it even more.

If you have a 16' crack that varies from hairline to 1 inch in width you have bigger problems than crack filler can cover up.
A crack that long and that wide is indicative of some serious movement of the slab. Find someone who knows what they're doing and get it stabilized. Not only has the slab moved an inch, but everything attached to it has moved an inch.
Crack filler in this case is just masking a serious structural problem.

I have had by best experiences filling concrete cracks with anchoring cement.

Yes, its likely an old slab and possibly didn't have enough if any rebar put in it!
OP: my dad wouldn't have input on filling cracks, unless you want to rip it all out and do it right! He didn't mess around with patch jobs b/c they weren't worth the $ and won't come out right (in his opinion).

I had about a half gal of 2-part epoxy and mixed it with concrete mortar. Filled a 30 ft half inch crack. Held up nice!

The ground is fairly Level, my property is Lake front and was Cleared to put a house on it. I have little doubt the crack is the result of the ground settling and being parked on too soon, the garage is solid, ive looked at the struckture and there is no risk of any of it coming apart, it was put together very, very well. I have inspected myself all the studs and Joyces and tehre is no risk of any of it coming apart. I asked the previous owner about the crack and he said it happend as he parked his 1500 pickup on it too soon after it was poured and it cracked.
