Assuming you are in canada with Petro-Can?  87, 89, 91 and 94 are fine. I mainly use 87 in my 6.2 and it runs fine. If in towing/hauling or off road, ill toss in 94 from cheveron (only have one in edmonton) since it has no ethanol.

If you want the full benefit of the 6.2 run 91 or higher octane.  Otherwise the engine keeps the timing retarded to prevent  knocking from the lower octane and so you loose power/performance.

You bought a 6.2L, enjoy the full power and performance of the engine, use nothing less than 91 octane in it! Otherwise there is a possibility to have the engine start knocking “per GM owners manual”

Maybe find one of these stations, then report back on how it ran on the "far left selection".

Oof, I was just in Seattle on a layover and gas was $3.35 there. Spokane was $3.25 and across the boarder in Idaho was $3.13 lol.

 

Needless to say I got fuel in Idaho before giving the rental back.

I dont we we have 93 in all of canada. Alberta and BC have 94, not sure what other provinces.  Its best not to use gas with ethanol as that will kill you fuel mileage compared to the same octane without it. I did a trip from Edmonton to Oliver BC (1000kms each way) to a race track and didnt want to fill up in BC with their high gas prices. So i filled up the truck just before the alberta/bc boarder with 91 from shell, had 55L of 91 from Canadian tire (same gas as shell) in jerry cans and was able to make it to the track back to alberta without stopping in BC for gas.

Nice so you're from edmonton i assume, i am from Fort McMurray my self. I checked every gas station here, didnt see any 93. 
 

so shell with 91 octane has no ethanol?

Yes im in Edmonton. And yes that is correct. Shell/Canadian Tire are from the same refinery so both are ethanol free. Also if you have Chevron yup there, the 94 from there is not only 94 ethanol free but its on a separate pump so no mixed fuel in the hose from the last user.
