"Cheap gas" will not be any different from "name brand"gas except for the munufacterer's additives, which are such a small percentage of the fuel as to make no difference at all in combustion. The raw distillate all comes from the same place, refinery. The only thing that will cause a ping id the octane level. A 91 octane from a Sunoco, an Exxon, or a Global is still a 91 octane.
You should hear a loud ping when either running at very low RPM under load try running in 5th gear at a low RPM and giving it some gas. Or run it up a hill, again in 5th gear at low rpm, you should also hear a loud ping.
If the engine really is pinging, take it to another dealer for a check. Wow, it sucks not being able to get 93 octane where you live! Yet this engine should run normally on 91 octane, says so in the manual.
