</>Common questions about Bottomless Tank
What does Bottomless Tank do in Construction Simulator?
Bottomless Tank keeps the fuel tank of every machine you drive in Construction Simulator permanently full. Flip the master switch on and your excavators, trucks, cranes and loaders stop burning diesel, so you never break a job to reach the depot or a fuel station. It's built for long earth-moving sessions and remote sites where refueling is a chore. Bottomless Tank is a premium mod in the ProjectMods catalog, the community-first PC mod manager and desktop app for 400+ games, and switching it off any time returns your machines to normal fuel use.
How does the Bottomless Tank master switch work?
Bottomless Tank runs off a single master switch called Enabled. Turn it on and the mod tops up every machine you climb into across Construction Simulator, keeping the gauge pinned at full no matter how long you dig, haul or drive. There's no amount to set and no per-vehicle menu to manage, so one flip covers whatever you're driving. Turn Enabled off and fuel starts draining normally again, so you can switch back to a realistic run whenever you like. Because it works on your current machine, swapping between an excavator, a dump truck and a crane keeps them all fuelled without any extra steps.
Does Bottomless Tank keep every type of machine fuelled?
Yes, Bottomless Tank tops up whatever machine you're actively driving in Construction Simulator, whether that's a compact excavator, a heavy dump truck, a mobile crane or a wheel loader. As long as the Enabled switch is on, the vehicle you're in holds a full tank, so hopping between machines on a big job never leaves you stranded with an empty gauge. It doesn't matter which manufacturer or class the machine is; if you can drive it, it stays fuelled. Turn the mod off and every machine goes back to burning diesel at its normal rate again.
Can I still let my machines burn fuel normally?
Yes. Bottomless Tank is deliberately simple, so the only control is the Enabled master switch, meaning it's all machines on or all machines off. There's no per-vehicle exception list in Construction Simulator, so if you want a realistic run where diesel actually matters, just leave the mod switched off. Flip it on for a long session when refueling would only slow you down, then flip it back off when you want the fuel gauge to mean something again. That on/off simplicity makes Bottomless Tank easy to drop in and out of a save without changing anything else about how your machines behave.
When is Bottomless Tank most useful in Construction Simulator?
Bottomless Tank shines during long, uninterrupted Construction Simulator sessions, like big earth-moving contracts, sprawling road builds, or remote job sites where the nearest fuel station is a long drive away. Instead of watching the gauge and planning depot runs, you keep digging and hauling until the work is done. It also pairs well with Turbo Diesel for fast cross-site trips that would otherwise drink fuel, and with Job Done when you're powering through a whole map's worth of contracts. Any time refueling feels like busywork rather than a fun part of the job, this is the mod to switch on.
What options does Bottomless Tank include?
Enabled
Master switch. Turn on to keep every tank topped up; turn off to fuel up normally again.
