Ok, after some time playing I realized it is not 2 minutes: it seems to be random, the about 2 minutes occurrence being just a "low dice row". That being said the wireless generator used up 3 gasoline cans while a regular generator used only 1. There is definitely something wrong going on here, it just seems very inconsistent and hard to reproduce.

And I am looking into the same issue. came back several times to the Wireless Generators empty of fuel. In the past I could set my AA Wireless Generators to max radius and it would consume less fuel than a generic generator. Now it consumes fuel at a rate of about 2 times faster than a generic generator. I do run both types since I started building vanilla before adding mods on my server.

note to the note: I am also having an issue with my AA Smithicator bottom where there are NO folders or engrams. I read in another thread that the issue is with using Super Structures; the OP switched to Structures + and said his smithicator is now working normally. I wonder if the issue is with Super Structures as I use this mod, myself. Also I now wonder if the generator issue is because of super structures.

You can control consumption with FuelConsumptionIntervalMultiplier, set it higher if you want less fuel to be consumed.

My issue had to do with mod load order. When I spoke with Blitz about it, he never mentioned this setting. When I searched the discord threads about the setting, it came up during the time period covering the 2.0 version.
